Umm I read from that link you provided and it's vegan propaganda. How is this diet natural and wholesome if a lot of foods that you're eating have to be 'fortified' with nutrients? That's not natural at all. Yeah, "sure you can go on this diet that's doesn't fill your nutritional requirements, just make sure you eat stuff that has been artificially fortified with all the good nutrients your body requires." How would you expect people in parts of the world who don't have access to these fortified foods to prosper on a vegan diet? Right, they can't. Don't try to use Indians as an example because a lot of them secretly eat meat. Plus, while they may not suffer from high obesity rates, they do have high rates of diabetes and heart disease. And they generally preform poorly in sports.

On a different note, consider this. Quinoa, which contains all of the essential amino acids, used to be the poor man's food in South America. Then one day, the white man discovers this 'super' food and starts marketing it to the masses of first-world folks. Eventually, the prices for quinoa quadruple, leaving the poor person there unable to afford their staple food and suffering health-wise because of that. How is that fair to those poor people who are now suffering because of this? How is that good for the environment? How much energy is wasted shipping those foods from far away countries to your local grocery store?

So you see there's negative aspects in regards to plant-based foods, not just meats. The Wal-Mart corporation does a lot of harm for the environment, why don't you boycott them instead of boycotting meat to feel better about yourself?
