Vegan

From Green Wiki

A vegan is a vegetarian who does not eat any animal products or by-products, including eggs, dairy, honey, and any meat or seafood. A vegan usually does not use animal products such as leather or wool either. Vegans are also known as "crazy people"

[edit] Impact on resource use and climate change

The production of animal products, not only meat, but also eggs and milk, needs much more energy than food from plants. Estimations are a factor between 7 and 10.

Because the methane they belch is 23 times more effective at trapping heat than CO2, livestock causes more global warming than all the human transportation systems combined. [1]

[edit] Impact on Human Health

Animal products are implicated in all kinds of human health problems. The obvious ones are things like obesity (meat and dairy are more calorie-dense than vegetative matter), and heart and artery disease (no cholesterol in plants). But the largest study of the connection between health and diet ever conducted (The China Study[2]) concludes that animal protein is a carcinogen, and is implicated in everything from diabetes to lupus.
