Effects of livestock wastes to the environment.According to the report of the United Nations food and Agriculture Organization (FAO) shows breeding industry has caused serious environmental problems such as soil degradation, climate change, air pollution, water shortages, water pollution, loss of biodiversity. The total area dedicated to livestock accounted for 26% of the surface area not covered with snow and ice of the Earth, added that is 33% of the cultivated land area are devoted to the production of animal feed. So the expansion of livestock lead to forest loss makes the soil erosion in the rainy season and drought in the dry season. In the process of raising the amount of CO2 emissions accounted for 9% and the amount of CH4 (a kind of gas has the ability to cause the greenhouse effect 23 times higher CO2) accounting for 37%. The amount of CH4 generated primarily in ruminant animals, the bacteria that decompose Cellulose in the grass to create energy is an anaerobic process, a process which caused the escape of gases CH4 through belching. Breeding process also generated 65% of the amount of NOx (capable of causing high greenhouse 296 times the CO2 doubling) and produces 2/3 of the total NH3 emissions, a major cause of acid rain destroys ecosystems. The world is currently facing serious freshwater shortages, according to predictions by 2025, the 64% of the population of the world will have to live in conditions of stress on water supplies. Meanwhile the development of livestock breeding increases water use demands we account for about 8% of the total amount of water used, and human waste water intake from animal husbandry was the environmental pollution by antibiotics, hormone, the chemical disinfectant, ... affecting human health. In addition livestock sector also reduces the amount of water added for the Lode due to forest loss and degradation, land hard bottles reduce possibility of osmosis. All of the negative impacts of livestock on the environment leads to the result is degrade biodiversity
