According to the book, Food Fight: The Politics of Food Industry, Kristin Wartman suggests that CAFO manure and fertilizer runoffs are one of the biggest main cause of pollution in oceans and lakes. Many industrial factories produce CAFOs - that contain fertilizers from the food they consume- to maximize their economic wealth. This results in large quantities of wasted manure, and will overtime, soak into the soil and pollute it. To add on, fertilized manure will travel down farm runoffs; creating a polluted sea, affecting the health of the marine animals, and will additionally pollute our air. Therefore, CAFO manure and fertilizer runoffs can significantly affect the environment.
