Why I am a Vegan

[xise]

By going vegan, America could feed an additional 390 million people, study suggests

Here's what they found:


Imagine an area of land that can produce 100 grams of edible protein from plants. If you take that same amount of land and use it to produce eggs instead, you would end up with only 60 grams of edible protein — an "opportunity food loss" of 40%, the study authors found.

And that was the best-case scenario.

If that land were used to raise chickens, it would produce 50 grams of protein in the form of poultry. If it were devoted to dairy cows, it would provide 25 grams of protein in the form of milk products. If that land became a home for pigs, they would provide 10 grams of protein in the form of pork. And if you put cattle there, you'd get just 4 grams of protein in the form of beef.
