Environmental problems

Agriculture may often cause environmental problems because it changes natural environments and produces harmful by-products.

Some of the negatives effects are:

Nitrogen and phosphorus surplus in rivers and lakes. Detrimental effects of herbicides, fungicides, insecticides, and other biocides. Conversion of natural ecosystems of all types into arable land. Consolidation of diverse biomass into a few species. Erosion Depletion of minerals in the soil Particulate matter, including ammonia and ammonium off-gasing from animal waste contributing to air pollution Weeds - feral plants and animals Odor from agricultural waste Soil salination in dry areas.
