And a top UN official is urging people to eat less meat in an effort to tackle climate change. Rajendra Pachauri, chair of the United Nations Intergovernmental Panel on Climate Change, told the London Observer, “In terms of immediacy of action and the feasibility of bringing about reductions in a short period of time, it clearly is the most attractive opportunity.” The animal welfare group Compassion in World Farming has calculated that if the average British household cut their meat consumption in half, it would cut greenhouse gas emissions more than if car use was cut in half.
