Lots of misinformation here on the impact of eating or not eating animals....
Approximately 40% of the worlds grain is fed to agricultural animals. Stop producing food animals and you free up all that food for human consumption. Or reduce it by have and you still have more food available. In the United States alone we feed enough grain to animals to feed at additional 840 million vegetarians. For every pound of meat produced 6 pound of grain are used. This means more water, fertilizer and land use for a meat based diet than for a plant based diet.
It takes about 220 gallons of water to produce 16oz of soybeans, and about 2000 gallons of water to produce 16 oz of beef.
