Did you know that roughly 9 billion animals are raised for dairy, meat and eggs each year in the U.S.? Most of these animals are crammed together by the hundreds or thousands. Not only do these factory farms have poor or nonexistent animal welfare standards—but they’re also environmental nightmares.
Here are the top five ways factory farms are hurting the Earth:
- Animal agriculture generates 18% of the world’s greenhouse gas emissions, including 9% of carbon dioxide, 65% of nitrous oxide emissions and 37% of methane emissions. Most of that methane comes from belching cows and rotting manure.
- In the U.S., confined animals generate three times more raw waste than humans generate. Their manure is commonly stored in open-air “poop lagoons,” which release dangerous toxins such as hydrogen sulfide, ammonia and methane into the air and leach heavy metals, drugs and other additives given to the animals into the ground water. That’s just gross!
- The waste is often used as crop fertilizer and over-applied to nearby fields, resulting in further air pollution and high levels of phosphorus and nitrogen in the water supply. Excess nitrogen robs water of oxygen and destroys aquatic life.
- Factory farms deplete our water by using large volumes for cleaning, cooling and drinking.
- The fossil fuels required to raise this staggering number of animals and produce their food emit 90 million tons of carbon dioxide worldwide every year. More than half of the world’s corn is fed to animals, and corn requires more nitrogen fertilizer than any other crop.
