Many vegans choose to omit meat, dairy, and eggs from their diet because of the inhumane treatment of animals in the agricultural industry. On large, factory style farms, animals are denied care, overfed or underfed, and eventually murdered. Even chickens that lay eggs or dairy cows live under torturous conditions and vegans choose not to support these practices.
Studies show that a vegan diet can have numerous health benefits. A whole foods vegan diet can improve health and combat diseases, such as heart disease, cancer, and diabetes. Some even commit to a raw diet to ensure the absorption of vitamins and minerals that dissipate during the cooking process.
Going vegan is part of sustainable living, a lifestyle in which people try to limit their impact on the Earth. Meat production causes pollution and uses up an abundance of natural resources, such as fossil fuels, water, and land. Studies have also suggested that world hunger would be alleviated by the focus on a vegan diet rather than a less sustainable meat diet.
Almost every religion has limitations on food consumption, either regularly or during periods of fasting. Certain religions require veganism or vegetarianism. These include sects of Hinduism and Buddhism. In Hindu sects, this stems from the notion of non-violence. To support killing or injury of animals would result in negative karma.
