In a 2013 report, the Food and Agricultural Organization of the United Nations (FAO) stated that 14.5 percent of all human-induced greenhouse gas emissions (GHG) came from the livestock sector. That is more than all cars, ships, planes, and other modes of transportation throughout the world combined. Of those emissions, 41 percent are caused by beef production, milk production makes up another 19 percent, pigs, chickens and eggs contribute most of the rest.
Producing meat requires massive amounts of natural resources. One kilo (35 ounces) of beef takes 15,415 liters (more than 4,000 gallons) of water to make. And an average person in an industrialized country eats 75.9 kilos of meat a year!
Since most lifestock these days doesn’t get to graze on endless prairies, the cow that is eventually turned into a burger usually gets fed soy, corn or other crops – food we could eat directly, saving a lot of energy and emissions in the process.
Growing all that food to feed our food takes space. A lot of it. That is particularly apparent in the Amazon Rainforest, where about 80 percent of deforestation is due to cattle ranching.
Happy eating!
