Vegetarian diets can easily meet all the recommendations for nutrients. The key is to consume a variety of foods and the right amount of foods to meet your calorie needs. Nutrients that vegetarians may need to focus on include protein, iron, calcium, zinc, and vitamin B12.

Protein has many important functions in the body and is essential for growth and maintenance. Protein needs can easily be met by eating a variety of plant-based foods. Combining different protein sources in the same meal is not necessary. Sources of protein for vegetarians and vegans include beans, nuts, nut butters, peas, and soy products (tofu, tempeh, veggie burgers).

Iron functions primarily as a carrier of oxygen in the blood. Iron sources for vegetarians and vegans include iron-fortified breakfast cereals, spinach, kidney beans, black-eyed peas, lentils, turnip greens, molasses, whole wheat breads, peas, and some dried fruits (dried apricots, prunes, raisins).

Calcium is used for building bones and teeth and in maintaining bone strength. Sources of calcium for vegetarians and vegans include calcium-fortified soymilk, calcium-fortified breakfast cereals and orange juice, tofu made with calcium sulfate, and some dark-green leafy vegetables (collard greens, turnip greens, bok choy, mustard greens). Calcium supplements are another potential source.

Zinc is necessary for many biochemical reactions and also helps the immune system function properly. Sources of zinc for vegetarians and vegans include many types of beans (white beans, kidney beans, and chickpeas), zinc-fortified breakfast cereals, wheat germ, and pumpkin seeds.

Vitamin B12 is found in animal products and some fortified foods. Sources of vitamin B12 for vegetarians include fortified breakfast cereals, soymilk, veggie burgers, and nutritional yeast. B12 supplements are another potential source.

 - Build meals around protein sources that are naturally low in fat, such as beans, lentils, and rice. Don't overload meals with high-fat foods to replace the meat. 

 - Calcium-fortified soymilk provides calcium in amounts similar to milk. It is usually low in fat and does not contain cholesterol. 

 - Many foods that typically contain meat or poultry can be made vegetarian. This can increase vegetable intake and cut saturated fat and cholesterol intake. Consider:

 - pasta with marinara or pesto sauce

 - vegan pizza

 - vegetable lasagna

 - tofu-vegetable stir fry

 - vegetable lo mein

 - vegetable kabobs

 - bean burritos or tacos

A variety of vegetarian products look (and may taste) like their non-vegetarian counterparts, but are usually lower in saturated fat and contain no cholesterol.

 - For breakfast, try soy-based sausage patties or links.

 - Rather than hamburgers, try veggie burgers. A variety of kinds are available, made with soy beans, vegetables, and/or rice.

 - Add vegetarian meat substitutes to soups and stews to boost protein without adding saturated fat or cholesterol. These include tempeh (cultured soybeans with a chewy texture), tofu, or wheat gluten (seitan).

 - For barbecues, try veggie burgers, soy hot dogs, marinated tofu or tempeh, and veggie kabobs.

 - Make bean burgers, lentil burgers, or pita halves with falafel (spicy ground chick pea patties).

 - Some restaurants offer soy options (texturized vegetable protein) as a substitute for meat, and soy cheese as a substitute for regular cheese.

 - Most restaurants can accommodate vegetarian modifications to menu items by substituting meatless sauces, omitting meat from stir-fries, and adding vegetables or pasta in place of meat. These substitutions are more likely to be available at restaurants that make food to order.

 - Many Asian and Indian restaurants offer a varied selection of vegetarian dishes.

Deforestation causes drastic loss of tropical forest biodiversity, and most deforestation occurs due to animal agriculture. Remaining areas of undisturbed and recovering forest provide the last refuge for many species unable to withstand the impact of human activity.

As one of the most comprehensive surveys of the impacts of disturbance on tropical forest biodiversity ever conducted, an international team of scientists found where forests had been cleared for animal agriculture, plant and animal life was impoverished and remaining species invariably consisted of the same subset of the original flora and fauna. There is irrefutable evidence that biodiversity is declining across the tropics due to animal agriculture.

The rapid growth of animal agriculture is the leading cause of deforestation. 70% of the Amazon Rainforest has already been destroyed and is now occupied by pastures and feed crops. One of the main crops grown in the rainforest is soybeans used specifically for animal feed. Tropical deforestation and forest clearing have adverse consequences that contribute to climate change, biodiversity loss, reduced timber supply, flooding and soil degradation.

Deforestation through farming also has a major effect on species loss and simplification across large areas. The lower species diversity in degraded forests indicates that many species are restricted to undisturbed forests. And the way in which they are altered by human activity has an impact on which species survives.

To preserve maximum species diversity, we must shift from animal-based agriculture to plant-based agriculture. Already 56 million acres of land are used to feed farmed animals, while only 4 million acres produce plants for human consumption. It takes 20 times less land to feed someone on a plant based diet than it does to feed meat eaters.

Studies have also determined that reserves should not be concentrated in one part of a region, but as a widespread network of forest reserves. These should include secondary forests where no primary forests remain. While there remains a widespread assumption that concentrating conservation efforts on the protection of isolated reserves is the best way to safeguard biodiversity, areas of private land already disturbed – which dominate much of the tropics – need to be maintained and protected as a wide network of forest areas. Without such a landscape-scale approach, many species will go regionally extinct.

The unsustainable ways in which we produce eggs, meat and dairy is damaging our environment. Switching to plant-based agriculture results in significant reductions in climate change, rainforest destruction and pollution of our air, water and land.

The food that people eat is just as important as what kind of cars they drive when it comes to creating the greenhouse-gas emissions that many scientists have linked to global warming, according to experts.

Both the burning of fossil fuels during food production and non-carbon dioxide emissions associated with livestock and animal waste contribute to the problem.

The average American diet requires the production of an extra ton and a half of carbon dioxide-equivalent, in the form of actual carbon dioxide as well as methane and other greenhouse gases compared to a strictly vegetarian diet. However close you can be to a vegan diet and further from the mean American diet, the better you are for the planet.

The average American drives 8,322 miles by car annually, emitting 1.9 to 4.7 tons of carbon dioxide, depending on the vehicle model and fuel efficiency. Meanwhile, Americans also consume an average of 3,774 calories of food each day.

Energy used for food production accounts for a large percentage of fossil fuel use. And the burning of these fossil fuels emits three-quarters of a ton of carbon dioxide per person. That alone amounts to approximately one-third the average greenhouse-gas emissions of personal transportation. But livestock production and associated animal waste also emit greenhouse gases not associated with fossil-fuel combustion, primarily methane and nitrous oxide.

An example would be manure lagoons that are associated with large-scale pork production. Those emit a lot of nitrous oxide into the atmosphere. While methane and nitrous oxide are relatively rare compared with carbon dioxide, they are--molecule for molecule--far more powerful greenhouse gases than carbon dioxide. A single pound of methane, for example, has the same greenhouse effect as approximately 50 pounds of carbon dioxide.

Vegan diets are the most energy-efficient. Fish and red meat are the least efficient. Research also indicates that plant-based diets are healthier for people, as well as for the planet.

Despite their reputation, pigs have many positive attributes including cleanliness, intelligence and a social nature. Pigs are indeed clean animals. Yes, they do roll in mud, but only because they can't sweat like people do; the mud (or water) actually keeps them cool. If available, pigs, who are excellent swimmers, prefer water to mud. Pigs also carefully keep their sleeping area clean, and will designate a spot as far from this area as possible for waste. Even piglets only a few hours old will leave the nest to relieve themselves.

Those who know pigs can't help but be charmed by their intelligent, highly social and sensitive nature. Pigs are actually more intelligent than any breed of dog. Like dogs, piglets learn their names by two to three weeks of age and respond when called. They are also very discriminating eaters, and are particular about their living space. Pigs enjoy novelty and are extremely active and inquisitive.

When free to roam, pigs spend much of their day enthusiastically smelling, nibbling, manipulating objects with their snouts and rooting ("nosing") about in the soil for tidbits. Rooting is so essential to a pig that some animal scientists say that "a rooting pig is a happy pig." Their powerful but sensitive snout is a highly developed sense organ. A pig's sense of smell is so keen that the animal is trained in France to unearth truffles. Using their snouts as shovels, pigs toss clumps of soil and twigs high into the air, searching for the rare and delicious fungus that grows underground near the roots of oak trees. They are also used by police to help search for drugs.

Few species are more social than pigs; they form close bonds with each other and other species, including humans. They are quite gregarious and cooperate with, and defend, one another. Adults in the entire social group will protect a piglet, leaving their own litters if necessary to defend an endangered youngster. If one pig starts to dig out tree roots, others invariably join in.

Touch and bodily contact are especially important to pigs. They seek out and enjoy close contact, and will lie close together when resting. They also enjoy close contact with people familiar to them; they like being scratched behind the ears and shoulders, and, at the touch of your hand, will grunt contentedly and roll over for a belly rub.

Pigs are vocal and communicate constantly with one another. More than 20 of their vocalizations have been identified. Pigs most often say "gronk" (more commonly known as "oink"), and will say "baawrp" when happy. They have an elaborate courtship ritual, including a song between males and females. Newborn piglets learn to run to their mother's voice, and the mother pig sings to her young while nursing. After nursing, a piglet will sometimes run to her mother's face to rub snouts and grunt. Pigs also enjoy music.

When she is ready to give birth, a sow selects a clean, dry area apart from the group, sometimes walking several miles to search for a good nest site and to gather preferred bedding materials. She hollows out a depression in the ground and lines it with grass, straw or other materials. For several days after her babies are born, she defends the nest against intruders. When her babies are five to ten days old, she encourages them to leave the nest to socialize with the other pigs.

Weaning occurs naturally at three months of age, but young pigs continue to live with their mothers in a close family group. Two or more sows and their piglets usually join together in an extended family, with particularly close friendships developing between sows. Young piglets play with great enthusiasm, play-fighting and moving or throwing objects into the air. Pigs appear to have a good sense of direction, too, as they have found their way home over great distances. Adults can run at speeds around 11 miles an hour, and can trot for relatively long distances.

Yet many pigs do not lead such noble lives; the hog industry confines many female pigs to farrowing crates, claiming these are necessary to protect piglets from being crushed by their careless mothers. Yet when given more room, sows are very gentle with their piglets. Before a mother pig lies down in a bed of straw, she roots around to make sure all the piglets are out, a safeguard against accidentally harming one of them.

Peacocks, also known as peafowl, are medium sized birds most closely related to pheasants. Peacocks inhabit warm climates of the Southern Hemisphere. All peacocks are believed to have originated in Asia, but they now inhabit Africa and parts of Australia. They are most common in India. Peacocks live in deserts, dry savannas, forests and dense foliage areas.

There are three main types of peacock, the Indian peacock, the African Congo peacock and the Green peacock. All three peacock species are known for the elaborately colored feathers and tales of male peacocks. Female peacocks are dull brown.

The giant tail feathers of male peacocks, called coverts, spread out in a distinctive train of over 60 percent of the peacock’s body length. It has vibrant eye shaped markings of blue, red, gold and other colors. Microscopic, crystal-like structures in the feathers reflect different wavelengths of light creating the bright, fluorescent colors.

The train of a peacock is used for mating and defense. Male peacocks attract female peacocks by showing off this array of elaborate feathers. When threatened, they also fan their tails out in order to look larger and intimidating. When the peacock quivers his feathers, they emit a low-frequency sound inaudible to humans. The peacock can change the sound to communicate different messages. Male peacocks shed their train each year after mating season.

Despite their giant tail feathers peacocks are able to fly, though they do not fly very far. When in danger, peacocks fly up into trees. They also spend nights in trees. Peacocks can also run quickly.

Male peacocks are called peacocks, while female peacocks are called peahens. Male peacocks are usually about twice the size of female peacocks. Male peacocks look especially larger than female peacocks when displaying their plumage (feathers). When male peacocks are not displaying, their tail feathers, called trains, drag behind them.

Peacocks are omnivores, feeding on plants, seeds, flower heads, insects, small mammals, amphibians and reptiles. They are known for their snake-fighting abilities.

Peacocks are social birds, but very aggressive towards invaders of their territories. They often play together, especially under the sunlight. Playing peacocks always follow one direction. Peacocks usually travel in groups of up to 10 peacocks.

Peacocks are one of the loudest animals on earth, calling out to each other during the morning and late evening. Peacocks make meowing sounds when it is going to rain. They also make alarm calls when they sense danger. Male peacocks sing to attract female peacocks.

During the mating season, male peacocks mate with up to six different female peacocks. Peahen lay 4 to 8 brown eggs. Mother peacocks incubate the eggs. Peacock babies hatch following an incubation period of about one month. Mother peacocks take care of the peacock chicks without assistance from the father peacock. Male peachicks do not begin to grow their trains until they are about 3 years old.

Peacocks have numerous natural predators, including dogs, cats, raccoons, tigers and the mongoose.

Peacocks live 20 years or more in the wild.

THREATS TO PEACOCKS

Peacocks are threatened due to habitat loss, smuggling, hunting and predation. Peacock populations are declining. Congo peafowl is a vulnerable species, and the Green peafowl is an endangered species.

The poaching of peacocks for their feathers is one of the main reasons peacock populations have decreased by more than 50 percent.

Peacocks face habitat loss like most bird species, causing them to have fewer sources of food, shelter and water. Mining, timber harvesting, animal agriculture, acquisition of their eggs, and hunting are all contributing to reduced numbers of peacocks.

Peacocks are also victims of the pet trade and animal entertainment industry.

Consumers who avoid meat for ethical and/or health reasons often still consider dairy foods nutritious and humane. But products made from cow's milk are far from "natural" for humans and anything but humane for cows and their calves.

Cow's milk is suited to the nutritional needs of calves, who, unlike human babies, will double their weight in 47 days (as opposed to 180 days for humans), grow four stomachs, and weigh 1,100-1,200 pounds within two years. Cow's milk contains about three times as much protein as human milk and almost 50 percent more fat. 

No other species besides humans drinks milk beyond infancy, and no other species drinks the milk of another species (except domestic cats and dogs, who are taught the habit by humans). After four years of age, most people develop lactose intolerance, the inability to digest the carbohydrate lactose (found in milk), because they no longer synthesize the digestive enzyme lactase. Lactose-intolerant people who drink milk can experience stomach cramps, gas, and diarrhea. By some estimates, up to 70 percent of the world's population is lactose intolerant.

In addition to being an unnatural food for humans, cow's milk, like other dairy products, is unhealthful. Dr. John A. McDougall calls dairy foods "liquid meat" because their nutritional contents are so similar. Rich in fat and cholesterol, dairy products, including cheese, milk, butter, cream, yogurt, and whey (found in many margarines and baked goods), contribute to the development of heart disease, certain cancers, and stroke our nation's three deadliest killers. Robert Cohen, author of Milk: The Deadly Poison, estimates that, by the time the average American is 50, he or she has consumed from dairy foods the same amount of cholesterol found in 1 million slices of bacon. Perhaps most surprisingly, the consumption of dairy foods has also been linked to osteoporosis--the very disease milk is supposed to prevent.

Osteoporosis is a debilitating disease characterized by low bone mass and deteriorating bone tissue. Contrary to the protestations of the dairy industry, this bone loss is not halted or prevented by an increased calcium intake so much as by a drop in protein consumption. Indeed, after studying the diets of 78,000 American women over a 12-year period, researchers at Harvard University concluded that "it is unlikely that high consumption of milk or other food sources of calcium during midlife will confer substantial protective effects against hip or forearm fractures"; participants in the study who consumed more than 450 milligrams of calcium from dairy foods per day actually doubled their risk of hip fractures. Foods high in animal protein, such as meat, eggs, and dairy products, leach calcium from the body in order to buffer the acidic byproducts that result from the breaking down of the excess protein; this causes a net loss of calcium. Societies with little or no consumption of dairy products and animal protein show a low incidence of osteoporosis. Furthermore, Dr. McDougall notes, "Calcium deficiency caused by an insufficient amount of calcium in the diet is not known to occur in humans."

Other illnesses are also more prevalent among those who consume significant amounts of dairy products than among vegans. Ninety percent of asthma patients who were put on a completely vegetarian diet (without meat, eggs, or dairy products) experienced great improvements in the frequency and severity of their attacks. According to the American Academy of Allergy, Asthma & Immunology, milk is the leading cause of food allergies in children, causing symptoms as diverse as runny noses, ear problems, muscle fatigue, and headaches. Dairy foods have also been implicated in congestive heart failure, neonatal tetany, tonsil enlargement, ulcerative colitis, Hodgkin's disease, and respiratory, skin, and gastrointestinal problems.

At least half of the 10 million cows kept for milk in the United States live on factory farms in conditions that cause tremendous suffering to the animals. They do not spend hours grazing in fields but live crowded into concrete-floored milking pens or barns, where they are milked two or three times a day by machines.

Milking machines often cause cuts and injuries that would not occur were a person to do the milking. These injuries encourage the development of mastitis, a painful bacterial infection. More than 20 different types of bacteria cause the infection, which is easily spread from one cow to another and which, if left unchecked, can cause death. 

In some cases, milking machines even give cows electric shocks due to stray voltage, causing them considerable discomfort, fear, and impaired immunity and sometimes leading to death. A single farm can lose several hundred cows to shocks from stray voltage.

Large dairy farms also have a detrimental effect on the surrounding environment. For example, in California, which produces one-fifth of the country's total supply of milk, the manure from dairy farms has poisoned hundreds--perhaps thousands--of square miles of underground water, rivers, and streams. Each of the state's more than 1 million cows excretes 120 pounds of waste every day equal to that of two dozen people.

Cows on today's farms live only about four to five years, as opposed to the life expectancy of 20-25 years enjoyed by cows of an earlier era. To keep the animals at high levels of productivity, dairy farmers keep them constantly pregnant through the use of artificial insemination. Farmers also use an array of drugs, including bovine growth hormone (BGH); prostaglandin, which is used to bring a cow into heat whenever the farmer wants to have her inseminated; antibiotics; and even tranquilizers, in order to influence the productivity and behavior of the cows. 

Many of the country's dairy cows are routinely injected with BGH, which manufacturers say increases a cow's production by 20 percent. That's not all BGH increases. According to the government warning that, by law, must accompany packages of the Monsanto company's BGH, the use of this hormone "has been associated with increases in cystic ovaries and disorders of the uterus" and may increase the number of cows afflicted with mastitis. The increased rates of infections in cows have led to an increase in the use of antibiotics at a time when scientists say the overuse of antibiotics has caused more and more strains of bacteria to become drug-resistant. Consumers Union, the publisher of Consumer Reports magazine, warns that higher infection rates in cows also mean more pus in the milk people drink.

Some researchers also worry about the long-term effects of consuming milk from BGH-treated cows. For example, Dr. Samuel Epstein, a professor of environmental medicine at the University of Illinois School of Public Health, believes such milk could increase the risk of some types of cancer in humans.

Perhaps the greatest pain suffered by cows in the dairy industry is the repeated loss of their young. Female calves may join the ranks of the milk producers, but the males are generally taken from their mothers within 24 hours of birth and sold at auction either for the notorious veal industry or to beef producers. If the calf is killed when young, his fourth stomach is also used in cheese-making; it contains rennin, an enzyme used to curdle (or coagulate) milk to turn it into cheese. Rennet, from whose membrane rennin is an extract, can also be used in this process. It is possible to make rennetless cheese (available at health food stores), but the close connection between the dairy, veal, and leather industries makes it cheaper for cheese producers to use calf parts than a vegetable-derived enzyme. 

Within 60 days, the cow will be impregnated again. For about seven months of her next nine-month pregnancy, the cow will continue to be milked for the fluid meant for her older calf. A typical factory-farmed dairy cow will give birth three or four times in her short life. When her milk production wanes, she is sent to slaughter, most likely to be ground up into fast-food burgers.

Reduce or eliminate milk and dairy products from your diet.

Rodeos are promoted as rough and tough exercises of human skill and courage in conquering the fierce, untamed beasts of the Wild West. In reality, rodeos are nothing more than manipulative displays of human domination over animals, thinly disguised as entertainment. What began in the late 1800s as a skill contest among cowboys has become a show motivated by greed and profit.

Standard rodeo events include calf roping, steer wrestling, bareback horse and bull riding, saddle bronc riding, steer roping and wild cow milking. 

The animals used in rodeos are captive performers. Most are relatively tame but understandably distrustful of human beings because of the harsh treatment that they have received. Many of these animals are not aggressive by nature; they are physically provoked into displaying "wild" behavior to make the cowboys look brave.

Electric prods, sharp sticks, caustic ointments, and other torturous devices are used to irritate and enrage animals used in rodeos. The flank or "bucking" strap used to make horses and bulls buck is tightly cinched around their abdomens, where there is no rib cage protection. Tightened near the large and small intestines and other vital organs, the belt pinches the groin and genitals. The pain causes the animals to buck, which is what the rodeo promoters want the animal to do in order to put on a good show for the crowds.

In a study conducted by the Humane Society of the United States, two horses known for their gentle temperament were subjected to the use of a flank strap. Both bucked until the strap was removed. Then several rodeo-circuit horses were released from a pen without the usual flank straps and did not buck, illustrating that the "wild," frenzied behavior in the animals is artificially induced by the rodeo cowboys and promoters of rodeo events.

Dr. C.G. Haber, a veterinarian who spent 30 years as a federal meat inspector, worked in slaughterhouses and saw many animals discarded from rodeos and sold for slaughter. He described the animals as being "so extensively bruised that the only areas in which the skin was attached (to the flesh) were the head, neck, leg, and belly. I have seen animals with six to eight ribs broken from the spine and at times, puncturing the lungs. I have seen as much as two to three gallons of free blood accumulated under the detached skin." These injuries are a result of animals' being thrown in calf-roping events or being jumped on from atop horses during steer wrestling.

Rodeo promoters argue that they must treat their animals well in order to keep them healthy and usable. But this assertion is belied by a statement that Dr. T.K. Hardy, a Texas veterinarian and sometime steer roper, made to Newsweek: "I keep 30 head of cattle around for practice, at $200 a head. You can cripple three or four in an afternoon . . . it gets to be a pretty expensive hobby."

Unfortunately, there is a steady supply of newly discarded animals available to rodeo producers when other animals have been worn out or irreparably injured. As Dr. Haber documented, the rodeo circuit is just a detour on the road to the slaughterhouse.

Although rodeo cowboys voluntarily risk injury by participating in events, the animals they use have no such choice. Because speed is a factor in many rodeo events, the risk of accidents is high.

A terrified, squealing young horse burst from the chutes at the Can-Am Rodeo and within five seconds slammed into a fence and broke her neck. Bystanders knew that she was dead when they heard her neck crack, yet the announcer told the crowd that everything would "be all right" because a vet would see her. Sadly, incidents such as this are not uncommon at rodeos. For example, in 1999, three men and seven horses died at the Calgary Stampede in Alberta, Canada.

In San Antonio, yet another frightened horse snapped his spine. Witnesses report that the horse dragged himself, paralyzed, across the stadium by his front legs before collapsing. During the National Western Stock Show, a horse crashed into a wall and broke his neck, while still another horse broke his back after being forced to buck. Bucking horses often develop back problems from the repeated poundings they endure. Because horses do not normally jump up and down, there is also the risk of leg injury when a tendon tears or snaps.

Calves roped while running up to 27 miles per hour routinely have their necks snapped back by the lasso, often resulting in neck and back injuries, bruises, broken bones and internal hemorrhages. Calves have become paralyzed from severe spinal cord injury, and their tracheas may be totally or partially severed. Even San Antonio Livestock Exposition Executive Director Keith Martin agrees that calf roping is inhumane. Says Martin, "Do I think it hurts the calf? Sure I do. I'm not stupid." At the Connecticut Make-A-Wish Rodeo, one steer's neck was forcefully twisted until it broke. Calves are only used in one rodeo before they are returned to the ranch or destroyed because of injuries. Frequently, animals break loose from their pens and escape. They are often shot by police unfamiliar with and untrained in capturing livestock.

Rodeo association rules are not effective in preventing injuries and are not strictly enforced, nor are penalties severe enough to deter abusive treatment. For example, if a calf is injured during the contest, the only penalty is that the roper will not be allowed to rope another calf in that event on that day. If the roper drags the calf, he or she might be disqualified. There are no rules protecting animals during practice, and there are no objective observers or examinations required to determine if an animal is injured in an event.

If a rodeo comes to your town, protest to local authorities, write letters to sponsors, leaflet at the gate or hold a demonstration. Check state and local laws to find out what types of activities involving animals are and are not legal in your area. For example, a Pittsburgh law prohibiting cruelty to rodeo animals in effect banned rodeos altogether, since most rodeos currently touring the country use the electric prods and flank straps prohibited by the law. Another successful means of banning rodeos is to institute a state or local ban on calf roping, the event in which cruelty is most easily documented. Since many rodeo circuits require calf roping, its elimination can result in the overall elimination of rodeo shows.

Processed meats are now considered “carcinogenic to humans,” according to the World Health Organization.

Recent estimates by the Global Burden of Disease Project, an independent academic research organization, found around 34,000 cancer deaths per year worldwide are attributable to processed meat.

The World Health Organization’s International Agency for Research on Cancer (IARC) delivered a damning report linking meat consumption and cancer. IARC is the leading authority that determines the cancer-causing risks of exposure to substances. IARC classifies substances from Group 1 (carcinogenic to humans) to Group 4 (probably not carcinogenic to humans).

Processed meat, according to WHO, refers to “meat that has been transformed through salting, curing, fermentation, smoking, or other processes to enhance flavor or improve preservation.”

WHO states that most processed meats contain pork or beef, but processed meats may also contain other red meats, poultry, offal, or meat by-products such as blood. Examples of processed meat include hot dogs, ham, sausages, corned beef, and beef jerky, as well as canned meat and meat-based preparations and sauces.

Processed meat has been given a Group 1 classification, putting it in the same class of cancer risk as tobacco smoking and asbestos. Red meat has been categorized as a Group 2A carcinogen, “probably carcinogenic to humans,” the same classification assigned to the pesticide glyphosate.

The Group 1 category is used when there is sufficient evidence of carcinogenicity in humans. In other words, there is convincing evidence that the agent causes cancer. The evaluation is usually based on epidemiological studies showing the development of cancer in exposed humans.

The recommendation was based on epidemiological studies suggesting that increases in the risk of several cancers may be associated with high consumption of red meat or processed meat.

In the case of red meat, the classification was based on evidence from epidemiological studies showing positive associations between eating red meat and developing colorectal cancer, as well as strong mechanistic evidence.

The IARC Working Group considered more than 800 different studies on cancer in humans (some studies provided data on both types of meat; in total more than 700 epidemiological studies provided data on red meat and more than 400 epidemiological studies provided data on processed meat). The IARC Working Group consisted of 22 experts from 10 countries.

One of the top causes of world hunger is the focus on the production of animal-based foods. A breathtaking 925 million people all over the world, mostly in the underdeveloped and poor countries of Africa and Asia, are suffering from hunger. Out of those, 870 million are suffering from malnutrition. The 925 million hungry outnumber the current population of the European Union, United States, and Canada, combined.

The world contains so many people plagued by hunger to almost fill up two continents. On a yearly basis, more than 2.5 million children under five years old lose their lives due to starvation.

Nonetheless, it is a fact that the Earth can provide enough food to nourish every last person on the planet. But, if that is so, how is it that people around the globe keep starving? A big part of the answer has to do with the production of food that is based on animals, such as dairy, meat, and eggs. Although there exists enough plant-based food to nourish the entire human population, most of the crops are fed to livestock for rich nations – not excluding the crops grown in starving countries. Add the fact that it takes a lot more plant food to produce animal-based foods causes a compromise of the food supply chain, ultimately leading humans to starvation. 

For example, consider the food (mostly comprising grains) that a cow consumes in its 18 to 24-month life (that’s when most cows are slaughtered for meat on average). If you could pile up all that food, you would end up with a mountain of food provided to the animal to live all those months. It gave him the required energy, it restored his cells, grew his muscles and bones, and allowed his heart to beat and his lungs to draw air. Now, imagine that cow is slaughtered and cut into pieces of meat. If you place the meat on a pile next to the first one, which one would be enough to feed more people? The pile of meat that comprised the cow’s body, or the mountain of grains that fed and nourished it? This equation is the basis of the unsustainability and irrationality of animal farming.

The production of soybeans and corn globally accounts for millions of tons. Approximately 40 to 50 percent of the corn and 80 percent of the soybeans are directed towards feeding animals that are to become human food.

In a study conducted by researchers from the Institute on the Environment and the University of Minnesota, scientists investigated agricultural resources and the problem of world hunger. It was found that if humans consumed the crops instead of feeding them to animals, the world supply would be enriched by approximately 70 percent more food, which would adequately support another 4 billion people. The surplus alone would be sufficient to feed more than half the Earth’s population, many times more than the 925 million hungry people of our time.

Livestock is doing a poor job converting the food they eat into muscle and energy, which is evident from the need to feed 13-20 pounds of grain in order to increase a cow’s muscle mass by 1 pound. The direct consequence is that 13 to 20 times more people could be nourished if those grains were simply consumed by them directly. In the same manner, approximately 7 pounds of grain are required for one pound of pork, and 4.5 pounds of grain are needed to grow one pound of chicken.

The animal agricultural system is even more flawed if you think that cows and other grazing animals, which provide dairy, meat, and leather, were never evolved to eat so much grain as the farming industry feeds them. They were meant to consume grass instead. But since current demands for animal products are so high, and farmers are compelled to increase their production quota and speed, they feed the animals immense amounts of grain like corn. That’s why industrial farming only needs 18 to 24 months to get a cow to the desired weight and then kill it. A constant grain diet (that could have fed many more humans instead), and growth hormones, make this possible.

Still, grass-fed livestock is far from a viable option. Grazing puts native and endangered species at risk through displacement and destruction of their habitat, while also causing erosion that can create deserts out of fertile farmland. According to reports by the U.N. Food and Agriculture Organization, approximately 70 percent of the Amazon rainforest has been cut and burned so that cattle can have more grazing space. In the end, regardless of being used to grow feed crops or to feed grazing animals, when land and other natural resources are exploited to produce animal food products, horrible inefficiency takes place.

Economic and political experts are projecting that water, food, land and other precious natural resources that humans need to survive will be the reason for future wars. As the human population has grown past the 7 billion mark in an ascending trend, it is only natural that resources will become even scarcer. The time for a solution to world hunger, a global crisis, has come, and what should be done is self-evident. If we want to ensure that every individual can be fed, we must contemplate deeply and pick the most healthy, compassionate and sustainable path. Veganism.

The American Medical Association passed a resolution that calls on hospitals to provide healthful plant-based meals and eliminate processed meats. Processed meats are considered “carcinogenic to humans,” according to the World Health Organization.

The American Medical Association’s House of Delegates adopted the resolution co-sponsored by the Medical Society of the District of Columbia and the American College of Cardiology.

"RESOLVED, That our American Medical Association hereby call on US hospitals to improve the health of patients, staff, and visitors by (1) providing a variety of healthful food, including plant-based meals and meals that are low in fat, sodium, and added sugars, (2) eliminating processed meats from menus, and (3) providing and promoting healthful beverages."

Numerous scientific studies show that healthful, plant-based meals can prevent and even reverse heart disease, diabetes and obesity. The AMA’s second recommendation, to remove processed meat from menus, is also supported by strong scientific evidence. The World Health Organization warns that processed meats are “carcinogenic to humans” and there is no amount safe for consumption.

The Physicians Committee—a nonprofit of 12,000 doctors—commended the AMA on its leadership in improving hospital food environments.

"Hospitals that provide and promote fruits, vegetables, whole grains, and beans are likely to reduce readmissions, speed recovery times, and measurably improve the long-term health of visitors, patients, and staff," stated James Loomis, M.D., M.B.A., medical director of the Barnard Medical Center.

The American College of Cardiology (ACC) also recommends hospitals improve patient menus by adding healthy plant-based options and removing processed meats.

"Too many heart disease patients have had their recovery undermined by bacon and hot dogs on their hospital trays," stated Physicians Committee president Neal Barnard, M.D. "Hospitals that ban processed meats and promote plant-based meals will do a better job at helping patients’ hearts heal."

A study published in the journal Preventive Medicine Reports also found that establishing hospital gardens for staff, patients and the community lowers obesity rates in the communities they serve and reduces public health disparities by providing easy access to fresh, healthy, plant-based foods.

The ACC’s and AMA's recommendations reflect the Physicians Committee's Make Hospital Foods Healthy campaign, which urges hospitals to improve patient and cafeteria menus by banning processed meats and offering more disease-fighting plant-based meals, and by hosting restaurants that offer only healthful, low-fat, cholesterol-free meals.

Humans like eating meat more than the thought of eating animals. Scientists conclude that humans choose not to really think about what we eat, because if we do we lose the appetite.

When we eat beef, chicken wings, hot dogs or spaghetti bolognese, we do it in denial. Already by referring to what we eat as “beef” instead of “cow”, we have created a distance between our food and an animal with abilities to think and feel.

“The presentation of meat by the industry influences our willingness to eat it. Our appetite is affected both by what we call the dish we eat and how the meat is presented to us”, says Jonas R. Kunst, a postdoctoral fellow at the Institute of Psychology, University of Oslo.

Kunst and his colleague Sigrid M. Hohle conducted five studies in Norway and the U.S. In the first study, chicken was presented at different processing stages: a whole chicken, drumsticks, and chopped chicken fillets. The scientists measured participants’ associations to the animal, and how much empathy they felt with the animal.

In the second study, participants saw pictures of a roasted pork – one beheaded, the other not. The scientists examined their associations to the animal, and to which extent they felt empathy and disgust. They also asked participants whether they wanted to eat the meat or would rather choose a vegetarian alternative.

Participants felt less empathy with the pig without a head.

“Highly processed meat makes it easier to distance oneself from the idea that it comes from an animal. Participants also felt less empathy with the animal. The same mechanism occurred with the beheaded pork roast. People thought less about it being an animal, they felt less empathy and disgust, and they were less willing to consider a vegetarian alternative.”

In a third study participants saw two advertisements for lamb chops, one with a picture of a living lamb, another without. The picture of the lamb made people less willing to eat the lamb chops. They also felt more empathy with the animal.

Philosophers and animal rights activists have long claimed that we avoid thinking about the animal we eat, and that this reduces the feeling of unease. This mechanism is described by the “disassociation hypothesis”. Celebrities have spoken up for the animals as well. Founder of Facebook, Mark Zuckerberg, ate only self-slaughtered meat for one year, claiming, “Many people forget that a living being has to die for you to eat meat”. Vegetarian Paul Mc Cartney said, “If slaughterhouses had glass walls, everyone would be vegetarian”.

Kunst and Hohle are the first scientists to test the hypothesis empirically, and it gains support from all five studies. We do have a tendency to distance ourselves from the thought of what we actually eat; this reduces discomfort and increases the willingness to eat meat.

In the three first studies, the scientists examined processing stages and presentation. In the next two studies, they investigated the use of words and phrases. They found that replacing "pork" and "beef" in the menu with "pig" and "cow" made people less willing to eat meat. The choice of words also affected feelings of empathy and disgust. Lastly, researchers investigated the effect of using the word "harvest". Traditionally the word has referred to plants, but in the U.S., it is now increasingly replacing words like "slaughtered" or "killed". The scientists found a clear effect: When the word "harvest" was used, people felt less empathy with the animal.

In total, more than 1000 people participated in the studies, and most of them were meat eaters. For some of them, eating meat was difficult, for others less so. Everyone disassociated meat from animals in their daily lives, but those that spent the most effort on disassociating were more sensitive when the presentations and descriptions of meat changed.

“We did not test whether these sensitive persons ate less meat than others in general. However, we all have a sensitivity in us, but this sensitivity is rarely activated because of the presentation of meat,” said Kunst.

He is not a vegetarian himself, but during these studies, he has become more aware of his meat consumption.

“The science results support a line of philosophers and animal rights activists who have said that the way meat is presented and talked about in our culture, makes us consume more of it”, said Kunst.

The results are published in the journal Appetite and might help authorities limit people’s meat consumption.

“For instance, authorities can influence people’s diets by presenting pictures of the animals in meat advertisements or contexts where meat is consumed. However, the will to do this is probably limited, since there are strong financial interests involved,” said Jonas R. Kunst.

The average consumer may not be aware of the suffering of billions of birds raised for meat and egg production in the United States each year. Billions of "broiler" chickens and "egg" chickens, and millions turkeys, are killed for food each year. In addition, millions of birds die as a result of disease, injury and during transportation.

Egg-laying hens in the United States number more than 459 million. Of these millions of birds, 97% are confined to "battery" cages, tiny cages roughly 16 by 18 inches wide. Five or 6 birds are crammed into each cage, and the cages are stacked in tall tiers. As many as 50,000 to 125,000 battery hens, in sheds with minimal light, strain to produce 250 eggs per year, ten times the number of eggs they would produce in the wild.

Battery cage confinement does not allow birds to turn around or take part in any other natural behavior, such as preening, dust bathing, and foraging for food. Prolonged forced confinement causes unnatural behaviors such as cannibalism and increases the incidence of disease and injury. Laying hens are also forced to live in a polluted environment due to toxic feed ingredients, accumulated feces, and excretory ammonia fumes. A successful battery system relies heavily on antibiotics that are routinely administered to laying hens to decrease the incidence of disease among these immune-repressed birds.

Battery hens often die in their cages as the result of disease or injury. Those who survive but stop producing adequately are considered "spent" hens and are sent to slaughter to be used for human and animal food. Male chicks are of no value to egg producers. Each year more than 200 million male chicks are killed or left to die after hatching.

Egg-producing birds that are not confined to battery cages seldom fare much better. Eggs labeled "Cage Free" or "Free Range" simply mean that the birds are not confined to battery cages, not necessarily that the hens are allowed a more natural existence. Neither guarantees that they have adequate space to move around, or that they are allowed outdoors to roam about and forage or dust bathe.

Molting is the natural process of shedding old feathers and the growth of new feathers. Molting initiates a new egg-laying cycle. The natural molting process takes about four months to complete. However, on factory farms, poultry producers induce starvation to control egg production in laying hens (eggs for human consumption) and breeding hens (eggs that hatch into birds used for meat or egg production) to reduce the molting period to one to two months. Performed to increase farm profits, this "forced molting" is extremely stressful to hens. Forced molting methods include food and water deprivation, medications and simulated light and dark cycles. A Poultry Science report found that forced molting in combination with a Salmonella infection created an actual disease state in tested hens. Salmonella infection can be passed on to consumers through egg consumption.

Debeaking is a painful procedure whereby the bird's sensitive beak is sliced off with a hot blade. Poultry meat and egg producers that use battery cages and crowded floor systems remove one-half to two-thirds of the birds' beaks to discourage cannibalistic pecking, a behavior that occurs when birds are kept in close confinement with no regard for their natural behaviors. Behavioral studies indicate that debeaked birds are often unable to eat, drink, and preen properly. They also exhibit behaviors associated with chronic pain and depression.

Toe-clipping is the amputation of a bird's toes just behind the claw. This painful procedure is performed to reduce claw-related injuries on factory farms.

Genetic engineering of broiler chickens and turkeys often results in a bird too heavy to stand or walk. They suffer from pain in their legs and sores on their feet that are induced by their extreme, unnatural size. Kept in polluted dark sheds with as many as 25,000 birds per shed, these birds suffer many of the same ailments as battery hens, such as being debeaked and being forced to live in a toxic environment. Thousands of these birds never make it to slaughter -- they will die while still on the farm from injuries, disease or their inability to reach food and water.

Millions of birds die during the loading of trucks and while en route to slaughter. These sensitive birds, often in very poor physical condition, are grabbed by their legs and thrown into densely packed cages to be transported by truck to slaughterhouses that are sometimes hundreds of miles away. Many die from shock, injury, and suffocation in the process.

The U.S. Federal Humane Slaughter Act does not apply to poultry, meaning that there is no federal law that requires birds to be stunned prior to slaughter. This allows for diversity in commercial poultry slaughter approaches and stunning equipment. When slaughterhouses do use stunning equipment, lack of regulation often results in birds allowed to raise their heads prior to reaching the water bath stunner and therefore not adequately stunned. Problems also exist in neck-cutting equipment, which may result in prolonged and extreme pain caused by necks improperly cut during the killing process.

Decrease or eliminate foods containing poultry products from your diet. The Dietary Guidelines for Americans published by the USDA and the U.S. Department of Health and Human Services endorses a vegetarian diet.

It’s starting to become common knowledge that animal agriculture is damaging our environment. While more people are switching to a vegan diet, and studies are being conducted that show the environmental impact, the world is waking up to the the link between environmental damage and animal agriculture.

While it may seem shocking, animal agriculture produces significantly more greenhouse gases than all of the traffic in the world combined. Spouting out huge percentages of carbon dioxide and nitrous oxide, the industry is leaving behind pollutants known to remain in the atmosphere for more than 100 years. Then there is the issue of animal waste which produces toxic levels of methane and ammonia, which leads to climate change as well as acid rain.

Livestock animals produce toxic excrement from the high levels of antibiotics and hormones they are given. Factory farming is responsible for 18% of CO2 greenhouse emissions and 64% of ammonia which creates acid rain.

Cows and sheep account for 37% of the total methane generated. Cows alone produce approximately 120lbs of manure per day, as many as 20 to 40 humans. And their manure produces about 150 billion gallons of methane per day. Methane is 25 to 100 times more damaging than CO2.

The overpopulation of animals in factory farms creates unmanageable amounts of waste which is collected in cesspools. It is either sprayed on fields or left to sit. The toxic fumes from the pools are emitted into the air and harm the environment – causing health issues to the people living in those areas.

In addition to the pollution of the air we breathe, animal agriculture is also destroying our waterways. Aside from the animal excrement itself, there are also hormones, antibiotics, pesticides, fertilizers and other chemicals running off into rivers, lakes, streams and our drinkable water. These practices are also causing dead zones in the oceans, rivers and lakes, leaving patches of underwater habitats with very low oxygen and causing marine life to die.

Animal agriculture is also using up our valuable water supplies. In the US 55% of water is consumed by animal agriculture, while only 5% is used by households. 1 cow drinks up to 50 gallons of water per day. It takes 683 gallons of H2O to make 1 gallon of milk. 2,400 gallons of water are used to make 1lb of beef. 477 gallons are needed to produce 1lb of eggs, and 900 gallons are used in the process of making cheese.

Animal agriculture takes up over 40% of the planet. Whole communities around the world have been displaced in order to make room for factory farms.

56 million acres of land are used to feed factory farmed animals, while only 4 million acres produce plants for human consumption. It takes 20 times less land to feed someone on a plant based diet than it does to feed meat eaters. 70% of the grain grown in the US is used to feed farmed animals. It takes 10lbs of grain to produce 1lb of meat.

Livestock factories lead to deforestation. As much as 80% of the Amazon Rainforest has already been destroyed and is now occupied by pastures and feed crops. Tropical deforestation and forest clearing have adverse consequences that contribute to biodiversity loss.

Nearly two thirds of land on our planet was once covered by grasslands, but much of these magnificent ecosystems have been lost to farming. The result is a catastrophic reduction of critical wildlife habitat. Remaining grasslands cover about half of African lands, while less than 4 percent of prairies survive in the United States.

Unlike sustainable farming systems that work harmoniously with the natural environment by rotating crops to help replace nutrients, unsustainable industrial farming uses one crop that is not rotated which leads to loss of soil fertility. Low soil fertility causes farms to continuously move from place to place which leads to deforestation and rapid growth in weeds.

The use of herbicides to combat weeds and pesticides to eliminate insects both harms the soil fertility and ultimately contaminates our water sources through runoff. Land based factory farming has caused more than 500 nitrogen flooded dead zones around the world.

For the the health of our planet and the future of its animals, agriculture must shift from animal production to providing vegetable based food sources. Reducing the devastation caused by animal factory farming begins with you. Choosing to buy vegan, 100% plant-based food and products is an easy way to help save the planet while also reducing the suffering of an animals.

Swimming gracefully across a pond or waddling comically across the land, ducks are a common feature of the landscape of most of America. There are statues devoted to them in a park in Boston, and every year that city holds a parade for the Bostonian ducklings. Walt Disney created the sputtering Donald Duck, and Warner Brothers followed with a less feisty, yet still speech-impaired, Daffy Duck.

Ducks are very social animals. Males and females sometimes live in pairs or together with their ducklings. They communicate both vocally and with body language. At other times ducks spend much of their time—during both day and night—in larger groups.

The domestic duck has a normal life span of ten years. By contrast, a pair of geese will get together to raise a family and, for the most part, will stay together the rest of their lives (up to 25 years), raising new families each year.

One of the most distinguishing characteristics of geese is that they form a giant "V" across the sky. This amazing trick actually helps each bird fly further than if flying alone. When a goose falls out of formation, she will feel the drag and move quickly back into formation to take advantage of the lifting power of the bird in front of her. When the lead goose gets tired, he rotates back into formation leaving another goose in the front position. They even honk to encourage those up front to keep up their speed.

Geese have very strong affections for others in their group (known as a gaggle). If one in the gaggle gets sick, wounded, or shot, a couple of others may drop out of formation and follow the ailing goose down to help and protect him. They try to stay with the disabled goose until he dies or is able to fly again, then they catch up with the group or launch out with another formation.

Much of a goose's time is spent foraging for food, most of which is obtained by grazing. They honk loudly and can stretch their long necks out to great length when scared or threatened.

Ducks and geese are wild animals, but they have domesticated counterparts who are raised for their eggs and meat, down and feathers. They're less commonly known as farm animals, yet they can certainly fall within this category.

When people think of goats, they often think of a clothesline-munching vagrant. Goats and sheep, however, are more often the source of clothing than the consumers of it. The fibers that become textiles—wool and cashmere, among many other types—are shorn from these animals.

Sheep and goats, like cows, are ruminant animals. They have a four-chambered stomach, using the first chamber to store food (cud) which they then bring back into their mouths to chew again before fully digesting it. These grazing animals often prefer noxious weeds and plants, which makes them great environmentalists.

Goats are shy at first, but will show adoration and devotion once you have gained their trust. They're frolicsome and have a gentle disposition, but when angered, they can retaliate quickly with a strong head-butt.

Goats are also clever animals who have been known to use their horns to open gates and feed bins, create and enlarge holes in fences, and batter down boards in confined areas. They also use their horns as back scratchers. Goats are most comfortable in groups, which are known as "tribes."

Like goats, sheep like to stick close to one another for comfort and security. Either black or white, these animals are incredibly gentle. Lambs form strong bonds with their mothers, but they have also been known to bond closely with humans. If a person hangs a piece of clothing outside, a goat who has bonded with that person will run to it for safety when frightened.

Goats and sheep deserve the same love and compassion from humans that they show to each other.

The veal calf industry is one of the most reprehensible of all the kinds of intensive animal agriculture. Male calves used for veal are taken from their mothers one or two days after birth. They are chained inside tiny crates barely larger than their bodies and are usually kept in darkness, except to be fed two or three times a day for 20 minutes. During their brief lives, they never see the sun or touch the earth. They never see or taste the grass. Their anemic bodies crave proper sustenance. Their muscles ache for freedom and exercise. They long for maternal care. About 14 weeks after their birth, they are slaughtered.

The veal calf's permanent home is a veal crate, a restraining device that is so small (22 inches by 54 inches) that the calves cannot turn around. Designed to prevent movement (exercise), the crate does its job of atrophying the calves' muscles, thus producing tender "gourmet" veal. The calves often suffer from open sores caused by the constant rubbing against the crates.

In 1996, the European Union voted to ban the veal crate across Europe. Yet it is still perfectly legal in the United States.

The calves are generally fed a milk substitute intentionally lacking in iron and other essential nutrients. This diet keeps the animals anemic and creates the pale pink or white color considered desirable in veal. Craving iron, the calves lick urine-saturated slats and any metallic parts of their stalls. Farmers also withhold water from the animals, who, always thirsty, are driven to drink a large quantity of the high-fat liquid feed.

Because of such extremely unhealthy living conditions and restricted diets, calves are susceptible to a long list of diseases, including chronic pneumonia and "scours," or constant diarrhea. Consequently, they must be given massive doses of antibiotics and other drugs just to keep them alive. The antibiotics are passed on to consumers in the meat and that's not all that's passed along.

Federal agents have found more than a dozen veal production companies giving calves clenbuterol, a dangerous and illegal drug that speeds growth and increases anemia in the calves, producing more expensive white meat. Calves treated with clenbuterol can be sold for slaughter at 12 to 13 weeks, rather than the standard 16 weeks. Even trace amounts of clenbuterol can cause severe illness in humans, including increased heart rate, tremors, breathing difficulties, fever and even death.

Veal calves are a byproduct of the dairy industry; they are produced by dairy cows, who are kept constantly pregnant to keep milk production high. Their female calves are raised to be living milk machines like their mothers...confined, fed synthetic hormones and antibiotics, artificially inseminated, and slaughtered after their milk production drops or they are slaughtered for the rennet in their stomachs (used to make commercial cheese). Since male calves cannot produce milk, they are often taken away from their mothers at 1 or 2 days old and put into crates to be killed for veal. The milk that nature meant for them ends up on our supermarket shelves instead.

Factory farming is an extremely cruel method of raising animals, but its profitability makes it popular. Farm animals are sentient beings that experience all the same emotions we do. The best way to save animals from the misery of factory farming is to stop or reduce your consumption of meat, milk, cheese and eggs.

Some of the most charismatic and versatile domesticated animals, mules have been used by humans for millennia, working as load-bearers, cart-pullers, and even racing mounts. The exact origin of the mule as a species isn’t known, but it’s likely that the first mules were the result of pairings between wild asses and horses that lived in the same habitats; this is a rare occurrence, though, and nearly all mules throughout history and up to modern days have been domestically bred by humans.

Mules were first popularly bred by the ancient cultures of Paphlagonia (a region that’s now part of Turkey), and they were used as valued pack animals in ancient Egyptian, Greek, and Roman civilizations. The mule was also seen as a highly valuable mount in many societies, often being reserved specifically for the use of royalty or nobility.

Christopher Columbus first introduced the species to the Americas in 1495, breeding together donkeys and horses that he had brought with him to the New World for the Conquistadores’ explorations.

The word ‘mule’ itself typically refers to the progeny of a mare (a female horse) and a jack (a male donkey), who, although they belong to two different species, are able to readily breed and produce offspring. Interestingly, foals of jennets (female donkeys) and stallions (male horses) pairings are called hinnies, but they’re far more rare in number, since a jennet’s body is far more efficient at detecting and defending against foreign DNA than a mare’s body. Both hinnies and mules fall under the same species and tend to be classified together as mules.

Although the adage ‘stubborn as a mule’ is widely quoted, in actuality, mules are truly intelligent survivalists, and won’t willingly put themselves in danger from overwork. They’re also widely praised as being anecdotally more patient than horses or donkeys, as well as stronger, more compliant and more curious than their donkey sires, making them hardy, enduring companions. The size and appearance of a mule can vary drastically from individual to individual, and really depends more on the size and lineage of their equine dam. Mules can range from miniature sizes, to smaller pony-types, to tall and lightweight physiques, and even up to moderately heavy weights when they’re bred from draft horses. On average, though, the weight range for a mule is between about 820 and 1,000 lb. In appearance, mules tend to have the thinner limbs, narrower hooves and short manes characteristic to donkeys, but the height, neck length, tail appearance and hindquarters are horse-like, as is their coloration. Mules can appear in sorrel, bay, black or grey, as well as (less commonly) roan, paint, and Appaloosa variations. These personable beasts also have a unique bray, which often sounds different from mule to mule – a humorous combination of ‘hee-haw’ and ‘whinny’.

A fantastic example of hybrid vigour (a phenomenon where hybrid offspring improve upon their parents), and more able to resist common diseases and parasites, mules can survive off of less nutritious fodder, and also typically have a longer lifespan than either horse or donkey. Their skin is less sensitive to pressure and changes in temperature and they’re also adaptable and able to better withstand more extreme climate conditions. Mule hooves are also narrower in size, but thicker and harder in material composition than those of horses.

A mule’s diet (entirely plant-based) tends to depend on the work they do, but, like horses and donkeys, they can thrive mainly on timothy or grass hays, or fresh pasture grazing. Unless they’re frequently working for long periods, most mules don’t need to eat richer alfalfa or grains, since they tend to use the nutrients in their food more efficiently than their equine parents. Mules also tend to be far less likely to consume toxic plants, and won’t generally overeat.

The major growth spurt for mules generally happens later than with horses - around 3-4 years of age - and some mules continue growing in height until they’re 8 or 9 years old. Aside from their slower development rate, the reproductive characteristics of mules are perhaps the most fascinating aspect of these animals. Mules (and hinnies) have 63 chromosomes, which differ from a horse’s 64 and a donkey’s 62. This means that chromosomal pairing typically doesn’t happen correctly if a mule were to mate, meaning that most mules are sterile (not able to produce offspring). There are a few recorded exceptions, however; as historical records since 1527 show 60 cases where foals were carried to full term and birthed from the mating of mule mares with male horse or donkeys.

THREATS TO MULES

Although the use of mules has declined enormously in North America with the introduction of industrial machinery in the late 20th century, mule breeders continue to breed these equids. They are often forced to perform more work than their small bodies can handle. Mules are sometimes kept as "pets", often poorly cared for. Many are left to fend for themselves. They develop deformed and crippled feet, become emaciated or obese and suffer from dental problems and parasite infestation.

Water buffalo, or Asian buffalo, are believed to have originated in Asia, but have been introduced to Africa, Australia, Europe and North America. Wild water buffalo inhabit tropical and subtropical forests. They live in swamps, grasslands, savannas, lowland floodplains, glades and mixed forests – never far from water.

Water buffalo spend much of their time submerged in muddy waters to keep cool and to remove parasites, flies and other pests. Water buffalo hooves are spread out to keep them from sinking into the mud. They are large members of the Bovidae family, the same family as wild cows, the American bison, the African buffalo, the zebu and the yak. The water buffalo is the second largest wild cattle species in the world.

Water buffaloes are black or white in color. They have large, distinctive, curved horns. Males have larger horns than females and are about a third larger than female water buffaloes. The horns of male water buffaloes are crescent-shaped with a ridge along the body of the horns.

Water buffalo live in herds of a few buffalo to hundreds of buffalo. Living in communities provides better protection against predators. Wild buffalo communicate using low grunts and calls. Water buffalo are social animals and are not territorial. Herds are usually led by a dominant, older, female – often accompanied by a single adult male. Water buffalo can be active during the day or night, with feeding usually occurring in the late afternoon and evening.

Water buffaloes are herbivores, feeding on a purely vegetarian diet. Water buffaloes eat aquatic plants when they are in water, but often leave the water to find grasses, herbs and leaves.

Water buffaloes once engaged in long-distance seasonal migrations. They now occupy stable home ranges. Water buffalo travel in single-file, lead by a female adult with calves in the middle and the remaining adults in the rear.

Water buffalo mating season takes place during the rainy season. Males may be aggressive with each other to earn females. After mating, a female water buffalo will chase away the male. The male water buffalo will then seek other females to mate with. Female water buffaloes have one baby every couple of years, following a gestation period of 9 to 11 months. Baby water buffaloes stay with their mother for several years. After about three years, male water buffaloes join all male water buffalo communities. Female water buffaloes often remain with their mother's herd. Older males may lead a more solitary life, or live near female communities.

Water buffalo are preyed upon by large predators including lions, tigers and crocodiles. Their horns are used to protect them against predators. Water buffalo can also run very fast when faced with danger. They are extremely protective of their calves. Female water buffalo will form protective lines in front of their young when threatened by predators. If the threat continues, they flee into forests, tall grass or water.

Water buffaloes can survive over 25 years in the wild and in captivity.

Wild water buffaloes are an endangered species due to loss of habitat and hunting, with less than 4,000 remaining. Their numbers are also diminishing as they are interbred with domesticated water buffalo.

The water buffalo has been domesticated by humans for thousands of years and is inhumanely used to pull heavy machinery, carry heavy loads, plow and transport people. Water buffalo are commercially farmed around the globe for their milk, skin, butterfat and meat.
