I may have mentioned that one of the friends that I hope to live with next year has recently become a vegan. I still have to do some research into these things, but from what he's sent me, it seems like I may be at least significantly reducing my intake of meat. My typical affluent diet includes some meat intake each day. I'm a meat-eater. And as such, I may be contributing to global warming and world hunger. Check out these facts:
A 2006 United Nations report found that the meat industry produces more greenhouse gases than all the SUVs, cars, trucks, planes, and ships in the world combined.
It takes up to 16 pounds of grain to produce just 1 pound of edible animal flesh.
Producing the grain that is used to feed farmed animals requires vast amounts of water. It takes about 300 gallons of water per day to produce food for a vegan, and more than 4,000 gallons of water per day to produce food for a meat-eater. You save more water by not eating a pound of beef than you do by not showering for an entire year.
It should be no surprise, then, that food for a vegan can be produced on only 1/6 of an acre of land, while it takes 3 1/4 acres of land to produce food for a meat-eater.11 If we added up all the arable land on the planet and divided it equally, every human would get 2/3 of an acre—more than enough to sustain a vegetarian diet, but not nearly enough to sustain a meat-eater.
