According to a 2006 report by the United Nations Food and Agriculture Organization (FAO), our diets and, specifically, the meat we consume, are responsible for more greenhouse gas emissions, such as carbon dioxide (CO2), methane & nitrous oxide, than all transportation modes combined. Intensive, industrial scale meat farming and government subsidies has turned meat from what used to be an occasional treat, to an affordable, everyday, every meal product. Demand for meat has increased globally as countries develop and population grows with the total amount of meat produced climbing from 70 million tonnes in 1961 to 160 million tonnes in 1987 to 304 million tonnes in 2012 (FAO 2012a) an increase of 300 per cent in 50 years.
