1 The Cost of Consumption: Pollution of the Livestock Industry Clemente Velasco-Annis University of Massachusetts, Amherst

2 Livestock Estimated 1.3 billion cattle worldwide 26% of the world’s landmass US Cattle and Beef Industry in 2010: – $74 Billion

3 Impact Greenhouse Gasses – Climate change and air pollution Deforestation – Grazing land and degradation Water Pollution – Water depletion and poisoning Loss in Biodiversity Policy Options

4 Greenhouse Gasses Energy reflecting off of Earth is trapped by greenhouse gasses inside the atmosphere. Enteric Fermentation CO 2, CH 4, NO 2 through belching In 2002, created 5.5 million tons of methane in the US 19% of the country’s methane emissions for the year. Emission through manure 4% of the country’s methane emissions for the year. Global CO2 emissions due to livestock processing: ~10 million tons / 30 million tons. Due to processed livestock transport: 0.8 million tons 65% of global NO2 emissions 64% of ammonia emissions

5 Deforestation 26% of the world’s landmass and increasing Pasture “Feedcrop” land Inflated price of land Intensification Multiple cropping Shorter fallow period Demand for meat Consequences of intensifiation” Erosion Decreased soil fertility Reduced biodiversity Eutrophication of rivers and lakes Pollution from application of fertilizers and degradation of land. Deforestation in the Amazon rain forest for grazing and feedcrop land

6 Water Pollution 2.5% of the world’s water is fresh water 70% of freshwater dedicated to agriculture Water use increasing Population of people living in water- stressed areas increasing. Feeding livestock Cleaning and processing Runoff from feeding area Over abundance of N and P in nearby bodies of water. Diseases transferred through water (for drinking or further for livestock processing. Feedcrop watering 45% of agriculture use water is for feedcrop

7 Biodiversity The endangered Peruvian Plantcutter of the Amazon Rain Forest Habitat and climate change Invasive species Narrowing genetic base of livestock and crops Overexploitation Competition with wildlife Direct competition Indirect competition over food and water Pollution

8 Policy Options Greenhouse gasses – Sequestering emissions – Improved diets – Improved manure management Water depletion/poisoning – Improved efficiency – Improved waste management Land use – Limitations on livestock land requirements – Correcting distorted land prices Institutional development Awareness building, education and information
