The animal agriculture industry’s toll on the environment is old news—the United Nations has been reporting for years that factory farms collectively produce more greenhouse gas emissions than the automotive industry. Recently, a study was released by Chalmers University of Technology that reveals that in order for humans to effectively combat climate change, we need to drastically alter our eating habits and decrease the amount of meat and dairy we consume. “We have shown that reducing meat and dairy consumption is key to bringing agricultural climate pollution down to safe levels,” says study author Fredrik Hedenus. “Broad dietary change can take a long time. We should already be thinking about how we can make our food more climate friendly.” The researchers also suggested that the government tax greenhouse emissions as a way to increase the price of meat and decrease animal consumption.
