Agricultural pollution

By-products and wastes from agriculture pollute water, soil, and air. The use of pesticides and fertilizers in food production also produce a range of dangerious pollutants. The waste from cattle, pigs, and other stock raise the level of nitrogen in water supplies to unacceptable levels. Where the stubble of harvested crops are burned high levels of air pollution result.

Agricultural production and animal farms often produce significant amounts of waste, which, when it's not effectively managed, can contribute to air and water pollution. Many communities, especially those in developing countries, dump sewage waste into the water system or directly on the streets. Without efficient sanitation systems, this can pose direct health risks in a contaminated water supply and ingested air particles.
