How do animals affect the environment?
The production of livestock and poultry has marked impacts on the environment influencing water, air, and soil. Manure or animal waste is the predominant source of concern particularly with intensive animal agriculture. At the time of writing, in the USA, livestock and poultry produce 120 million metric tons of manure in dry weight. Some researchers put the impact of animal agriculture at 27% of total human water usage globally for the production of livestock (including water used to grow the feed grains). When there are problems in management, livestock and poultry can reduce water quality. There is contamination of water from livestock and poultry facilities including phosphate and nitrate, pathogens (viruses, bacteria, and protozoa), antibiotics, and androgenic agents. Nitrates and phosphate contamination of waterways and estuaries is leading to algal blooms, eutrophication, and hypoxic areas. Antibiotics are used extensively in pig and poultry production while anabolic agents are used for cattle. Agriculture contributes 11% to global greenhouse gas emissions with ruminants adding methane. Among the gases from livestock and poultry that are potential problems are the following: carbon dioxide, ammonia, total reduced sulfur including hydrogen sulfide, and water vapor together with odors. The latter can be offensive to neighbors of farms and have the potential to impact human health. Moreover, viruses can be transmitted from animal facilities to humans via aerosol particles. Livestock contribute markedly to soil degradation with effects including erosion, salinization (due to freshwater removal), soil loss following erosion after deforestation or overgrazing, “compaction and crusting (of soils) can be caused by cattle trampling,” and waterlogging with water-impaired movement. Soil degradation related to livestock directly and indirectly is made up of overgrazing of rangeland (679 million ha globally) and deforestation (579 million ha globally).

For example, open meadow habitats are important for species like waterfowl, amphibians and for pollinators. Some species even increase in number due to agricultural activities.
Why do grasslands exist?
Grasslands provide habitat to a great number of animals and native plants. These areas have been almost entirely wiped out in other countries of Europe due to modern development or intensive agriculture. In Romania, however, they still exist because of the traditional (low-impact) way of farming and seasonal grazing of livestock by shepherds.
Why is maintaining land important?
Maintaining land for agricultural use can also prevent that land from being developed and urbanized, in areas where native species have difficulty finding original habitat. The United States Department of Agriculture Farm Service Agency (FSA) created seven voluntary land conservation programs for this purpose.
How do plants and trees help the aquifer?
Plants and trees in agricultural systems help to retain and add water to underground aquifers. This process is most effective when the crops being grown are perennials that continue to grow every year and have deep, well-established root systems.
