How Factory Farms Affect the Environment
Transcript of How Factory Farms Affect the Environment
They pollute waterways with manure
They pollute waterways with antibiotics
Antibiotics that pass through the animals they are fed to end up in the billion tons of manure produced annually. This manure, if not spilling out of open-air lagoons, is being sprayed on nearby fields, and it then drains into waterways, making more animals and humans resistant to antibiotics.
Fun Fact: 80% antibiotics produced in U.S. are fed to animals
Animals release a significant amount of methane
Cows can release 250 - 500 liters of methane a day, which means that cattle alone contribute to 2% of greenhouse gases causing global warming.
They have a huge water footprint
85% of the world's water usage comes from agriculture! And the biggest portion of that 85% comes from growing feed for the animals!
Fun Fact: 68% of grains produced in U.S. are for animal feed
According to the Natural Resources Defense Council, manure is placed in massive, open waste lagoons that are prone to spills.
In 1995, a lagoon burst in North Carolina, spilling 25 million gallons of waste and killing 10 million fish in the New River.
In 2011, a lagoon in Illinois burst, spilling 200,000 gallons and killing 110,000 fish.
They clear land excessively for livestock raising
70% of the world's agricultural lands are used for livestock and cattle alone have caused 80% of deforestation in the Amazon.
