"The livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems , at every scale from local to global . The findings of this report suggest that it should be a major policy focus when dealing with problems of land degradation , climate change and air pollution , water shortage and water pollution , and loss of biodiversity . In the report , senior U.N. Food and Agriculture Organization official Henning Steinfeld reports that the meat industry is Â “ one of the most significant contributors to todayÂ ’ s most serious environmental problems `` [ 3 ] and that `` urgent action is required to remedy the situation . '' [ 4 ] Other points the report makes are that the world 's livestock industry `` generates 65 per cent of human-related nitrous oxide , which has 296 times the Global Warming Potential ( GWP ) of CO2 `` [ 5 ] and `` that livestock are responsible for 18 percent of greenhouse gas emissions , a bigger share than that of transport .
