Environmental ethics is the philosophy that considers extending the traditional boundaries of ethics from solely including humans to including the non-human world. There are many ethical decisions made by humans with respect to the environment.
A vegan is someone who tries to live without exploiting animals, for the benefit of animals, people and the planet. Vegans refrain from consuming animal products, choosing instead from thousands of animal-free foods and products. Veganism is a philosophy, not a diet. This philosophy is the belief in the right of all sentient beings to be treated with respect, not as property, and to be allowed to live their lives. Choosing to live a life free from animal products means choosing a path that is kinder to people, animals and the environment.
