The actions of humans have created many threats to wild animals. As human populations increase, these threats multiply, leading to a fewer number of some species, and total extinction of others. All animals contribute to the ecology of the earth and are vital to its health and continuation.
Many wildlife species are threatened with extinction, and many critical wildlife habitats are being destroyed. The need for conservation was created by human beings. The problems are large and complex—requiring the combined efforts and cooperation of numerous groups, organizations and agencies around the world. But most importantly, preservation and protection of wildlife and their habitats starts with each individual human.
Together, we all play an important role in protecting wild animals and their homes. By joining a conservation organization, welcoming wildlife into your yard with native plants, reducing and recycling, refraining from using of herbicides and pesticides, and speaking out for wildlife and nature, you can help wild animals everyday.
Mammals are animals that have warm-blood, fur or hair and usually have live babies. A few mammals lay eggs rather than giving birth to live babies, including the platypus and the spiny anteater. All mammals have some type of body hair or fur, though marine mammals, like dolphins and whales, are almost hairless. Over 5,500 species of mammals have been recorded to date.
Birds are warm-blooded, covered in feathers and lay eggs. All birds have wings, a beak and stand on two legs. Most birds fly, but some cannot. Some species, particularly penguins and members of the Anatidae family, are adapted to swim. Some birds eat only seeds and berries. Some also eat insects. Birds of prey eat small animals. Male birds are usually more brightly colored than females, while females have better camouflage.
