Washington Post article tells us the grim story of how manure is becoming one of the largest environmental problem we now have.
Animal manure, a byproduct as old as agriculture, has become an unlikely modern pollution problem, scientists and environmentalists say. The country simply has more dung than it can handle: Crowded together at a new breed of megafarms, livestock produce three times as much waste as people, more than can be recycled as fertilizer for nearby fields.
That excess manure gives off air pollutants, and it is the country's fastest-growing large source of methane, a greenhouse gas.
And it washes down with the rain, helping to cause the 230 oxygen-deprived "dead zones" that have proliferated along the U.S. coast. In the Chesapeake Bay, about one-fourth of the pollution that leads to dead zones can be traced to the back ends of cows, pigs, chickens and turkeys.
Maybe this is part of the reason why most enviro-nutters are vegens.
