Hi Everyone! In today’s post, I would be sharing a short discussion around a Hog farming pollution problem in North Carolina. This post was inspired by a youtube video created by Vox. Do check out the video below
The video described a massive problem with industrial Hog farming, where a large number of animals are kept in small places producing large amounts of manure. The manure is then sprayed into a nearby crop field as a waste disposal strategy. However, this releases a large amount of Methane, Carbon dioxide, Ammonia and Hydrogen Sufied into the air. This was found to increase rates of Asthma, Respiratory diseases, headaches and even premature death in the area.
Furthermore, when manure enters groundwater and water bodies, this releases nitrates, phosphorus and Fecal bacteria that cause illnesses in people and algae blooms.
Currently, one of the potential solutions to this poop problem is to process and treat the waste before using it for irrigation. See the diagram below provided in the video. However, this solution is not economically viable and has not been implemented.
This incident illustrates the complexity of solving pollution from food production. As long as consumers are price-sensitive, producers have little incentive to reduce the intensity of farming and properly manage waste from food production. Stay tune for more blog posts on food production.
