16 weeks of green

Many environmentalists underestimate the impact of reducing meat consumption. Nearly 60 percent of the carbon footprint of the average American diet comes from animal products, and meat is responsible for land degradation, water pollution, and the direct endangerment and death of wildlife.


Meat consumption is a major driver of climate change, the extinction crisis and many other environmental problems. Animal agriculture accounts for at least 14.5 percent — and, according to some studies, as much as 51 percent — of greenhouse gas emissions (more than cars, trains and airplanes combined). From growing feed crops to livestock grazing to handling the 500 million tons of manure generated by U.S. livestock each year, meat production destroys natural habitat and ecosystems at an alarming rate. And wildlife also pays a direct price in order to protect the meat industry’s profits: Whether they pose a potential threat of preying on herds or eating livestock feed, native species are routinely killed by Big Ag, often in great numbers and ruthlessly.
