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.

Impact on resource use and climate change Edit

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]

Impact on Human Health Edit

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.
