UN Food and Agriculture Organization (FAO) reports that cattle-rearing generates more global warming greenhouse gases (ie methane), as measured in CO2 equivalent, than transportation.
Methane is roughly 23 times more harmful as a greenhouse gas than CO2. 37% of all human-induced methane emissions are produced by livestock.
Nitrous Oxide is even worse, at 296 times the Global Warming Potential (GWP) of CO2. The livestock sector generates 65% of human-related nitrous oxide, mostly from manure.
30% of the earth’s entire land surface is used directly for livestock, with another one third of all arable land used to produce feed for those livestock.
Demand for livestock production also induces forest clearance. 70% of Amazonian deforestation has been to create areas for grazing.
