Effects of Soil Erosion Essay examples

When you think of problems in the world today, water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain water and most need water to survive, so water pollution is a big problem. If severe, the pollution can kill off birds, fish, and any animals that use the water source. In some cases even killing an entire species.

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

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).

The polluted water supply that results can become harmful to humans. Aquatic life quickly suffers the effects of watershed pollution.

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

Franklin D Roosevelt once said, “the history of every Nation is eventually written in the way in which it cares for its soil.” The United States began seeing sustainable management practices in farms, and healthier soil through this act. In 1982 through 2007, the United States soil erosion had declined by 43%” (Montanarella, 2015). Every year the United States loses about $400 billion dollars due to crop soil that is eroded. Soil is a limited resource and the largest resource for growing food, accommodating diverse ecosystems, and providing food resources. Therefore laws, acts, and provisions are necessary to protect this natural resource.

Congress declares soil erosion “a natural menace”. Under Hugh B. Bennett, the SCS will develop programs to save the topsoil and irreparable damage to the land. New farming techniques are put in place and farmers are paid to practice soil-conserving techniques as

The chemicals found in water can be dangerous toward our health. We live near the Great Lakes which supplies 20% of the World’s fresh water. It also has chemicals that threaten the life evolving around the fresh water. There are medical drugs that are being introduced to the fresh water lakes. Stuff like antibiotics and steroids. These pharmaceuticals are posing danger for the environment. This could affect the lake life,s growth.

While rain does help replenish and dilute polluted fresh water, it also can contaminate it just as fast. Sewage waste and runoff fills the waters with pathogenic microorganisms and chemicals that reduce the dissolved oxygen levels. A loss in oxygen kills off fish and leaves their habitat murky and dark. High levels of nitrogen and phosphorus from runoff cause growth of algae and other harmful aquatic life. In an article on water pollution, it is stated that “many fish species require a minimum of 4–5 mg of dissolved oxygen per liter of water” (Scholz, Nathaniel). Scholz is saying that fish in the areas that become over polluted die off or are forced to leave their natural environment due to a lack of oxygen. The article continues to explain that the fish living in these poor conditions are consumed as food and the levels of toxins can multiply as it goes up the food chain, potentially leading to illnesses for humans. As more water is demanded, more water filtration plants are put into place to get consumable water to all in need. One gallon of contamination can make one thousand gallons of water undrinkable. In 1993, Michigan received heavy amounts of rainfall which affected Lake Michigan and the drinking water. The study of this incident is included in John Gary’s book, Can We Cope?, and is stated that:

Because of farm fertilizer, an excess quantity of nitrogen and phosphorus can be wash down

Water pollution is when, “one or more substances have built up in the water to such an extent that they cause problems for animals and people” (Woodford). Water pollution is also bad for humans and animal’s health. Sewage, chemicals, radioactive waste, oil pollution, and plastic, are some causes for water pollution (Explain That Stuff). When water from rain runs off roofs and roads into rivers it carries away trash, toxic chemicals, dirt, and harmful organisms (NRDC Water). Some solutions to these are to throw things into the correct bin, use water wisely, and not throw chemicals, oil, paints, and medicine down the sink, drain, or toilet. Also plant lots of trees and have cities develop a sewage treatment plant to minimize pollution (eSchool Today). It’s important to protect our

According Oraclethinkquest, "Water pollution has the potential to have a harmful effect on all living things including plants and animal species. Chemicals, radioactive waste, industrial waste in the water can affect species and their development. There is no

The chemical pesticides used in farming affect the quality of water because of run off which then go into lakes or rivers. In chapter four, Carson concentrates on the water pollution caused by pesticides. The pollution can be unsafe for use and causes fish to die. An example used is a study done by the United States Fish and Wildlife Service in 1960 that showed that “our waters have become almost universally contaminated with insecticides.” (pg.41) The pesticides are especially threatening to groundwater which is an important source of drinking water for humans. Consequently, the chemicals in pesticides can cause cancer and other harm effects on our health. Another issue is that the pesticides in water and can mix with other chemicals and become a new chemical. Therefore, it can lead to the creation of an unknown chemical with harmful

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

Erosion removes the surface soils, containing most of the organic matter, plant nutrients, and fine soil particles, which help to retain water and nutrients in the root zone where they are available to plants. Thus it affects the productivity of plants. The remaining, the subsoil, tends to be less fertile, less absorbent and less able to retain pesticides, fertilizers, and other plant nutrients. There are over 17,000 soil types recognized worldwide. They vary widely in structure, erodibility, fertility, and ability to produce crops. A generalized soil profile for a humid, temperate climate is showed. When the natural vegetation is cleared for agriculture, soils become exposed to erosion and loss of soil fertility. The removal of the above-ground natural
