Industrial Animal Production System

Pig Production
Resource | Risks (-) and opportunities (+) | Underlying factors
Land | (-) Toxic levels of nutrients in soils | Poor management of animal wastes
(-) Chemical pollution of soils | Poor management of chemical inputs
(-) soil pollution with heavy metals (Copper, Zinc and Cadmium) | Poor management of animal wastes
(-) destruction of vegetation by acid rain | Ammonia emissions from animal wastes
(+) improved soil fertility | Appropriate management of animal wastes. Balanced application of pig manure to the land
Water | (-) pollution of surface and ground water | Poor management of animal wastes Poor management of chemical inputs
(-) depletion of fresh water resources | Increased use of fresh water
Air | (-) global warming: emissions of Carbon Dioxide, Methane and Nitrous Oxide | Increased greenhouse gas emissions
Biodiversity | (-) loss of genetic diversity | Loss of local breeds
(-) increased susceptibility to diseases | Loss of disease resistance
