Meat production is one of the main drivers of environmental degradation globally, and the crisis is rapidly growing worse. Production of beef, poultry, pork and other meats tripled between 1980 and 2010 and will likely double again by 2020. This ever-increasing meat consumption in a world of more than 7 billion people is already taking a staggering toll on wildlife, habitat, water resources, air quality and the climate. And Americans eat more meat per capita than almost anyone else. By eating less or no meat, we can take extinction off our plates and improve our own health along with the health of the planet.
How Meat Consumption Threatens the Environment
Livestock vs. Wildlife
From wolves to elk to prairie dogs, wild animals pay the price of meat production. Some are killed because they prey on cows; others die en masse to make room for agricultural operations; still more are put in harm’s way by pollution and greenhouse gas emissions that exacerbate climate change.
According to the United Nations, meat production is responsible for 14.5 percent of global greenhouse gas emissions — more than all forms of transportation combined. Nearly 60 percent of the carbon footprint of the average U.S. household diet comes from animal products.
Habitat Loss, Water Use and Pollution
The 500 million tons of manure produced annually by U.S. livestock is just the beginning: Animal agriculture has taken over nearly half the landmass of the lower 48 states. And it has polluted 35,000 miles of rivers in 22 states and groundwater in 17 states.
