Basically, our issue that we researched is about the negative effects of agriculture on the environment. So here is some basic information about the environmental degredation from agribusiness.

  • Agriculture increases CO2 levels in the atmosphere from the burning of plants and destruction of plant life to convert forests into fields
  • “Agriculture causes harmful levels of pathogens and chemicals in our water and increases levls of greenhouse gases in the air as a result of agriculture”
  • Waterbourne diseases can be found in water systems near animal farms, including Salmonella typhimurium, Cryptospordium parvum, and Giardia duodenalis
  • Harmful bacteria can also be found in food and water near the animal farms including C. jejuni, Campylobacter, Salmonella, and E. Coli
  • Animals from farms can cause overgrazing of the grass, which leads to erosion and salinization
  • Erosion and salinization of the land can lead to the eutrophication of water by adding too much nitrates and phosphates to the water
  • Animal wastes cause a salinity problem due to the large amount of salt in the feces. Each cow defecates about 100 pounds of feces per day (84 pounds of wet, 16 of dry), which contain a lot of nitrates, which can harm the soil or can drain into water systems
  • Cows produce 20% of the methane gas that goes into the atmosphere
  • Animal farms indirectly cause acid rain, because they produce over 100 types of pollutiong gases, and 2/3rds of the amount of ammonia that goes into the atmosphere
  • Agriculture uses up to 80% of the water usage in the United States, which can cause water shortages in many parts of the country
