This document discusses the environmental impacts of animal agriculture. It notes that 75% of global soy production is used to feed livestock in the meat, dairy and egg industries rather than being consumed directly by humans. Animal agriculture is responsible for 71% of deforestation in South America between 1990 and 2005 due to cattle grazing. Producing animal products, especially meat and dairy, requires significantly more water than producing plant-based foods. The animal agriculture industry produces over 5 tons of waste for every US citizen each year, far exceeding human waste production and causing widespread water and air pollution. Other impacts discussed include greenhouse gas emissions, ocean dead zones, overfishing, marine debris, and the environmental footprint of different milk options.
