So these farmers are mixing up 750,000,000 pounds of chemicals in their barns every year, I guess. They’re definitely not buying 750,000,000 pounds of chemicals from gigantic corporations.
It’s been shown that U.S. farmers have actually used 750 million pounds of some 20,000 different agricultural chemicals in just one year,[21] and those that have been used to kill insects and weeds that threaten crop yields end up poisoning natural ecosystems. Plus, as some weeds and bugs have developed resistance to these compounds over the years, chemists have continued to create ever more powerfully-toxic pesticides that are even worse for the environment.
The residues of these chemicals are found at every level of the food chain, and—through the process of bioaccumulation—become more concentrated the higher up the chain one looks. Meaning, in a system that runs the gamut from micro-organisms to humans, people who eat animal products get the highest dosage of toxins.
Water Pollution
The National Water Quality Inventory report of 2002 noted that agricultural runoff was “the leading cause of river and stream impairment and the second leading cause of impairment in lakes, ponds and reservoirs”[22] which includes fertilizer runoff that typically occurs when rain carries fertilizer into waterways. Runoff from both synthetic fertilizers and animal waste can poison drinking water and aquatic ecosystems, wreaking havoc on human health[23] and wildlife.[24] In the Southern U.S. , where there is an abundance of chicken factory farms, as many as one-third of all underground wells fall below EPA safe drinking water standards for nitrate, a form of nitrogen concentrated in chicken waste.[25]
