A question from Yahoo! Answers:
Why do people continue to buy and eat meat even though we could solve world hunger if we were all vegetarians?
We could solve world hunger, vegetarian or not. In fact, it can be said that we have solved world hunger; the world consistently produces more food than it consumes. Some governments, however, like to have wars that drive people off their lands, so they can’t feed themselves. Others like to monopolize international trade in foods, so people can’t buy what they lack abroad.
