The regular use of these drugs in the food and water of farm animals to (poorly) help them survive the often crowded, unsanitary, and stressful conditions at CAFOs contributes to the rise and proliferation of antibiotic-resistant bacteria. From fertilizer runoff to methane emissions, large-scale industrial agriculture pollution takes a toll on the environment.
