Cowspiracy takes a somewhat extreme view on this, but the overall message is correct. IPCC numbers estimate the emissions from agriculture at 24%, though that may not count full life cycle costs or the effects of damaging ecosystem carbon sinks. It's scientific consensus that agriculture, and especially ruminant animal agriculture is one of the largest contributors to climate change. https://www3.epa.gov/climatechange/ghgemissions/global.html https://www3.epa.gov/climatechange/ghgemissions/global.html This proportion is also likely to go up significantly in the next 30 years. If you want to get a more visceral sense of that, try changing the "Diet" settings in this climate change mitigation model http://tool.globalcalculator.org/ http://tool.globalcalculator.org/ . For more of an eye opener, change the "examples pathways" to IEA 6DS (current trends) and then just manipulate the "Type of meat" parameter. Simply by replacing 64% of expected ruminant consumption (beef, lamb etc.) with other meats (chicken, pork, etc.), we can decrease total worldwide emissions by 43%.
