Animal Agriculture Causes Global Warming
In a groundbreaking 2006 report, the United Nations (U.N.) confirmed that raising animals for food generates more greenhouse gases than all the cars, trucks, SUVs, planes, and ships in the world combined. Senior U.N. Food and Agriculture Organization official Henning Steinfeld reported that the meat industry is “one of the most significant contributors to today’s most serious environmental problems.”
Carbon dioxide, methane, and nitrous oxide together cause the vast majority of global warming. Raising animals for food is one of the largest sources of carbon dioxide and the single largest source of both methane and nitrous oxide emissions. A recent University of Chicago report determined that going vegan is 50% more effective than switching from a standard American car to a hybrid.
