Livestock environmental impact. Raising livestock generates 145 per cent of global greenhouse gas emissions that are very bad for the environment. Based on the most recent data available Livestocks long shadow impacts plus the environmental effects of related land use changes and production of the feed crops animalsconsume. Section 12 addresses air pollution and climate-change related impacts.
It is organized by medium of impact. Livestock production has a major impact on the environment. At present this methodology has been widely used in livestock systems of beef 222331 pork 112632-34 and chicken 2627333536.

The application of process engineering principles and. Diesel equipment used on the farms may also be contributing to reduced air quality. It finds that expanding population and incomes worldwide along with changing food preferences arestimulating a rapid increase in demand for meat milk and eggs while globalization is boosting trade in both.
Livestocks presence in vast tracts of land and its demand for feed crops also contribute to biodiversity loss. Intensive livestock farming generates secondary particulate matter PM formation especially ammonium nitrate as a consequence of ammonia NH 3 emissions from animal manure and urine and has been estimated to have a substantial impact on air quality.
