Animal agriculture inefficiently consumes natural resources, contributes to deforestation, and produces immense quantities of animal waste, threatening water and air quality and contributing to climate change. The Food and Agriculture Organization (FAO) of the United Nations estimated in 2006 that animal agriculture was responsible for 18% of global, anthropogenic, or human-induced, greenhouse gas emissions and was ―by far the single largest anthropogenic user of land. Climate change poses significant challenges to India‘s agricultural sector, which is already facing increased competition for land and water.
