    It’s also really important to talk about water pollution. In the U.S., industrial agriculture has polluted 48% of river and stream water and 41% of lake water. The EPA’s list of drinking water contaminants will tell you the source of each of these bacterial and chemical pollutants–fertilizer factories, soil runoff, and animal waste definitely come up more than once or twice.

    On a traditional farm, where animals and plants were raised together, waste could cycle back and forth between elements of the farm. But it’s no secret that industrial agriculture tries to concentrate as many livestock into as little space as possible. The result: far too much animal waste with no clean way of disposing it. Thus, manure and its pathogens overflow into our water table. Fertilizers and pesticides also end up in our water–both inorganic compounds and macronutrients. Nitrogen and phosphorus are necessary for all plant life, yes, but it is possible to have too much.
