Document Summary

Livestock production impacts air, water quality, ocean health, and greenhouse gas emissions. Livestock production uses the largest land space altogether globally. Beef production requires 28 times more land, 11 times more irrigation water and. 5 times more greenhouse gas emissions than the average of the other livestock categories. Cropland where food and feed are grown is the central, limiting resource for food production. Greenhouse gas emissions from the agriculture sector account for about 22% of total global emissions. Similar amount of emissions as industry sector. Methane and nitrous oxide contribute much more to this sector"s warming effect than co2. Therefore, halting the increase of greenhouse gases from agriculture, especially livestock production. Livestock production however is expected to increase substantially over the next. Total requirements, including pasture land, amount to ~3. 7 million km2, equivalent to ~40% of us land. Feed production requires ~ 45 billion m3 of irrigation water, which is equal to.
