Agriculture Pollution

Excess pesticides can end up in the water supply due to runoff water or seepage through the soil.

Furthermore, factory farms pollute drinking water sources. Manure and fertilizers are rich in nitrates and phosphates, which are very unhealthy for living things. They pollute groundwater sources by seeping in through lagoons of waste sewage that factory farms create. Lagoons of animal feces and spent fertilizers are a very cheap way of dealing with waste (NRDC). The chemicals travel through the soil to groundwater that the local communities depend on. Ingesting nitrate tainted water will lower the amount of oxygen a person can intake. This can lead to death for infants. Some of the pollutants can reach open waters if they are carried by rain or irrigation water, called runoff. Runoff pollutes ponds, lakes, oceans, and other open bodies of water. Polluted waters with high levels of nitrates kill fish, aquatic plants, and other aquatic organisms because they experience the same problems with oxygen intake. High levels of phosphorus in our waters cause algae blooms in open bodies of water. Algae blooms disrupt the ecosystem in the water and kill the organisms living in the water. They use up all the oxygen in

Pesticides and preservatives are not only harmful to human beings, but they are also harmful to our environment and ecosystems. Pesticides used in organic farming may run-off and contaminate nearby bodies of water. If enough contaminated run-off from pesticides and artificial fertilizers get into water, it is able to poison animals and fish that live there. According to Raloff, recent studies have demonstrated that exposure to hormones has a substantial effect on the gender and reproductive capacity of fish, throwing off the natural cycle, (1). This is not only harmful to the animals that live there, but if enough fish are dying because of poisoned run-off, the fish industry could suffer and it will affect humans as well. The same chemicals that poison bodies of water could seep into our groundwater and affect the well water we drink and use daily. This does not happen with organic farming, because no chemicals are ever sprayed on the fields and there is much more run off because of tilling practices.

Although the amount of pollutants from a single town or construction site may seem insignificant, the combined concentrations of contaminants threaten our lakes, streams and wetlands. When things such as: human and animal waste, decaying plants and animals, discarded litter, or food waste enter surface waters, either dissolved or suspended in stormwater runoff, they can deplete the supply of dissolved oxygen in the water. When dissolved oxygen is reduced below a certain critical level, it can impair or kill aquatic plants and animals (CNYRPDB, 2011).

Environmental Protection Agency (EPA), "High levels of nitrogen and phosphorus in our lakes, rivers, streams, and drinking water sources cause the degradation of these water bodies and harm fish, wildlife, and human health." In the 2000 National Water Quality Inventory, states reported that agricultural nonpoint source (NPS) pollution was the leading source of water quality impacts on surveyed rivers and lakes, as well as the second largest source of impairments to wetlands, and a major contributor to contamination of surveyed estuaries and groundwater. Agricultural activities that cause NPS pollution include poorly located or managed animal feeding operations; overgrazing; plowing too often or at the wrong time; and improper, excessive or poorly timed application of pesticides, irrigation water and fertilizer. Since the 1960s, the high input of agriculture production has resulted in the surplus of nitrogen and phosphorus in farm fields, which run off into surface waters. High concentrations of nitrates and phosphates in surface waters could lead to eutrophication and instability of the aquatic ecosystems. Eutrophication is caused by the over-enrichment of water with phosphates and nitrates, a problem that has become a widespread in rivers, lakes, estuaries, and coastal

Other pollution sources include chemical plants, coal-fired power stations, oil refineries, nuclear waste disposal activity, large animal farms, plastic factories, and metal production factories. The soil becomes contaminated by many chemicals and pathogens; this passes on to humans through direct contact via food and water. Overuse of pesticides and chemical fertilizers causes toxins to enter the food chain.

Agricultural societies were sedentary, which means the members lived in one place for pretty much their whole life. As a result of this, the waste products that were produced by the people build up and were hard to eliminate safely. This was definitely not an issue for hunter-gatherer and pastoral societies, as they were always on the move so filth was just left in one area while the grouped moved on. Pollution accumulation is a vast problem across the world, that was started at the beginning of agriculture. It has detrimental effect on people and the environment. When I was driving by a large lake in my town, I noticed that there were several bottles, cans, plastic bags, and other waste things. The only way this happened is because many people settled in this area since agriculture requires a stationary lifestyle. Prior to the Agricultural Revolution, humans would leave a little waste behind and move on, which barely had an affect on the environment. My local library had records on the fertilizers and pesticides used in the area over the last few decades, and I realized that agriculture has demanded the use of more fertilizers to increase crop supply. This fertilizer can be washed away by rainwater, and end up in bodies of water where it can kill fish. The Agricultural Revolution is the main reason why there is such enormous amounts of

Agricultural runoff is another big factor in water pollution and it is similar to the storm water process but only with more dangerous pollutants. Agricultural waste runoff from the barnyards finds its way into the drainage emerging with the water bodies. The runoff from the barnyard being polluted by the multiple fertilizers used in the crops, pesticides, and livestock waste. Then the polluted water from the runoff makes contact with the water bodies such as lakes and rivers polluting them. There are two essential chemicals for the growth of crops and livestock: nitrogen and phosphorus. However, nitrogen and phosphorous are very dangerous chemicals when they make contact with water or soil. High concentrations of nitrogen and phosphorus in

The pesticides are not only poisonous to the insects and larger animals, but also to the people who live on the land. Another item that plays a big role in the pollution is the fertilizer used by the farmers, and that also enters the water systems. Not to mention it also destroys all of the other sensitive vegetation in the area. Once the fertilizer enters the water it makes the algae grow at increased rates while killing the organisms that feed on it. The final result is the algae overwhelming the other aquatic plants and life, while restricting water flow.

REMIEDIATING AGRICULTURAL WATER CONTAMINATION Remediating Agricultural Water Contamination: Problem, Solution, and Barriers Paper Problem Concerns about water pollution are generally focused towards sources that are highly visible and chemically oriented. However, the greatest causes of water contamination and quantity abuse in the United States come from agricultural production (United States Environmental Protection Agency [EPA], 2012a), which is defined as a nonpoint source that pollutes with nutrients. In 2011, nine

Industrial or commercial farming places a large amount of pressure on our natural resources, and us as humans. Animals in these factories produce an extreme amount of fecal wastes, which leads in pollution of our air, land, and water. The residents who live in areas where industrial farming takes place have already seen and personally lived through the outcomes of such horrendous form of food production. It is known that industrial farming effects our health, but there is more to this. Residents who live near these kinds of areas face lower property values because of how close they live to these factories and the contamination that has spread into their homes and possibly in their bodies. In addition, the natural cycle of renewal is interrupted when

One concern about pesticides and herbicide usage is the amount of residues left on the end product of crops sprayed with the chemicals, and their effects on human health. (Williamson, 2007, p. 184). However, these effects are closely tested and levels are strictly regulated to ensure there is no danger from possible pesticide residues. Since 1910, many rules, regulations, and agencies have been formed to monitor the safety of the pesticides and herbicides used in conventional farming. These chemicals must meet specific safety standards in order to be registered for use, and regulations on levels of each product safe for use are also put in place. (Tafel et al.,2007, p.184). All pesticides are rigorously examined to ensure they have no significant effects on human health, or the environment. The residues in the food chain are closely monitored, and regularly tested, to ensure they are below legal limits. In a recent survey of residues

Current conventional farming practices are also responsible for many pollution problems that would not exist otherwise. The land where we live and grow our food, the water we drink, and the air we breathe are all being contaminated. The large amounts of synthetic pesticides and fertilizers used on our crops are poisoning the soil, air, and water. Toxic heavy metals such

The largest source of contamination is runoff from land. Toxic runoff can be sewage, rainwater flowing over exposed topsoil, flooding or agricultural runoff. Rain can cause runoff of chemicals or waste that can seep into creeks, rivers and other waterways that lead to the ocean. Some of the chemicals found could be antibiotics or waste from animals, pesticides from crops or from pollutants, originating in the air, which have settled on land and washed away. Unless a solution to pollution runoff is found, this type of contamination will continue indefinitely and contribute to the deterioration of the ecosystem in the

One of the leading causes of water pollution is from agriculture. Some of the reasons for this are that agriculture is close to most bodies of water, agriculture is the most widespread land use in the U.S., and agriculture uses chemicals and nutrients to improve production. Figures
