Livestock and Climate Change
by Robert Goodland and Jeff Anhang
Livestock and Climate Change: What if the key actors in climate change are…cows, pigs, and chickens?
The environmental impact of the lifecycle and supply chain of animals raised for food has been vastly underestimated, and in fact accounts for at least half of all human-caused greenhouse gases (GHGs), according to Robert Goodland and Jeff Anhang, co-authors of “Livestock and Climate Change”.
A widely cited 2006 report by the United Nations Food and Agriculture Organization, Livestock’s Long Shadow, estimates that 18 percent of annual worldwide GHG emissions are attributable to cattle, buffalo, sheep, goats, camels, pigs, and poultry. But recent analysis by Goodland and Anhang finds that livestock and their byproducts actually account for at least 32.6 billion tons of carbon dioxide per year, or 51 percent of annual worldwide GHG emissions.

1.3 billion tons of animal waste produced in the U.S.
Pollution strength up to 160 times greater than raw municipal waste.
Animal wastes contribute to large oceanic “dead zones,” which extended to nearly 7,903 sq. miles in the Gulf of Mexico during Summer of 2007.
In the U.S. alone, livestock is responsible for:
- 55% of erosion and sediment
- 37% of pesticide use
- 50% of antibiotic use
- 33% of nitrogen and phosphorus in freshwater
