Factory farming's downsides seem to be on everybody's mind these days, so here's one more to consider: It's creating an ungodly amount of pollution. Just Tyson Foods alone, one of the world's biggest meat producers, is responsible for dumping more crap into U.S. waterways than almost every other big company, according to a new report by eco-advocacy group Environment America. Companies are required to report pollution from their processing plants to the EPA, and Tyson's numbers make it the country's second-worst polluter from 2010 to 2014, the most current year on file. It gets edged out by steel-and-coal behemoth AK Steel Holding -- 104 million pounds of discharges into waterways, versus 107 million -- but the Department of Defense is a distant third with 63 million pounds. In fact, by this rubric, Tyson pollutes more water than Cargill and ExxonMobil put together, or, for one more fun comparison, more than rivals Pilgrim's Pride and Perdue Farms plus Koch Industries.
