"More than a third of all raw materials and fossil fuels consumed in the U.S. are used in animal production. Beef production alone uses more water than is consumed in growing the nation’s entire fruit and vegetable crop. Producing a single hamburger patty uses enough fuel to drive 20 miles and causes the loss of five times its weight in topsoil. In his book The Food Revolution, author John Robbins estimates that 'you’d save more water by not eating a pound of California beef than you would by not showering for an entire year.' Because of deforestation to create grazing land, each vegetarian saves an acre of trees per year."
i am not going to start preaching vegetarianism to my friends over meals, but... just know that you prevent a *lot* of environmental damage by not eating meat. not to mention saving yourself from many health problems. think about it?
