Water Is An Important Factor That Affects Sorption

However, agriculture is the central issue. While pesticides are being used to keep crops alive, a benefit to farmers, the natural ecosystem is not exactly experiencing the same effect; the ecosystem is being destroyed. An effective way agriculturists can improve on decreasing the amount of pesticides is to use continuous production, where it is reusing the fields, without wasting and hurting them.

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

The Everglades used to be a very beautiful tourist attraction, but have been largely affected by the existence of pesticides. However, the majority of pesticides is not specifically targeting the pest only but they also affect non-target plants and animals during their application. The Effect of pesticide runoffs on the Everglades is destroying one Florida’s major tourist attractions due to the cultivation of sugar cane just to mention one of those responsible and creates a loss of natural habitat, water pollution, and threatens existence of wildlife. Many pesticides are not easily degradable; they persist in soil, leach to groundwater and surface water and contaminate wide environment.

Modern farming and agricultural operations contribute to the degradation and contamination of our environment as well as the neighboring ecosystems. Fertilizers, pesticides, herbicides, animal manure and other Argo-chemicals are rich in chemical nutrients and toxic substances which are often the major sources of agricultural pollution. The use of these various types of products can affect water quality when it rains, and the contaminated soils and water is washed into the waters or into ground waters. These chemicals can also be absorbed by plants which are then consumed by animals and even humans, harmful to animal and human health. There are many causes of this pollution.

San Joaquin County is known for its heavy usage of pesticides and is one of the 15 counties in California that has been labeled for using heavy amounts of these chemicals. Pesticides are a chemical based spray that is used upon crops of fields to prevent damage to the crops being grown by farmers. Pesticides have been able to form a multibillion dollar industry alongside the farming industry. While some pesticides have been deemed as unsafe for the county, state population; they are used in spraying over our crops and can lead to a health and safety risk for the population.

However, pesticides are used to control pests, which include insects, mice and other animals, unwanted plants (weeds), fungi, or microorganisms like bacteria and viruses. Often misunderstood to refer only to the insecticides, the term pesticide also applies to herbicides (that control weeds), fungicides (that control fungi), and substances used to control other pests. In addition, because many pests tend to travel between farms, resistance to pesticides can evolve at an inefficient rate. Farmers can increase the economic efficiency of chemical use by adapting integrated pest and resistance management practices, such as rotating crops and pesticides, reducing reliance on a single pesticide, adjusting planting and harvesting dates, scouting fields, and using more benign, and biological control

By using these chemical pesticides on the plants, it causes dissolved oxygen depletion in the water, phytotoxicity to the plants, and poisons the animals (Environmental Effects of Pesticides). From the greediness of crop cultivation, millions of species of fish will disappear. These pesticides do not only get into the ocean by spraying it, they get into the ocean when small particles fly over from the drift of the wind. This is especially common at beaches where people spray chemicals on the grasses nearby to prevent other people from being bitten by insects. Not only do pesticides affect the oceans, but the plants as well. These pesticides cause phytotoxicity refers to plant injury. By using these chemical pesticides, it damages the plants, especially those genetically similar to weeds. They can progressively result in mutations little by little until eventually there will be a period of time where the plants now will be very different. Even though this is what is happening now, Hawthorne, an author from 200 years ago, also thought that scientists were being evil. In “Rappaccini’s Daughter,” when it states “Dost thou deem it misery to be endowed with marvellous gifts, which no power nor strength could avail an enemy?...Wouldst thou, then, have preferred the

This suggests that the roadsides was once beautiful and bloomed with healthy and lively vegetation; however, they are now destroyed due to the use of pesticides. From these examples, it can be shown that even though pesticide is beneficial, its deadly effects outweigh its benefits; in addition, it is a dangerous substances to the environment, organisms, and even human.

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

"It is not possible to add pesticides to water anywhere without threatening the purity of water everywhere. Seldom if ever does Nature operate in closed and separate compartments, and she has not done so in distributing the earth's water supply" (Carson 42).

America the Beautiful! So why are we destroying it everyday with the use of pesticides? It has been proven that pesticides have affects on it's surrounding, although made to improve earths resources, they typically take there negative effect on the environment in time. Pesticides affect more than the environment; they also affect the animals and humans living in the environment. There are alternative, to this major problem but, we as the caretakers of earth must act fast. In the following paper I'm going to share with you what pesticides are. I'll tell you why they are not safe to use and some of the affects of pesticides. Last, I will talk about some new alternatives there are

The chemicals that are sprayed on the ground, even household weed killers, have a tendency to wash into local streams and rivers with the first rain. This has caused many incidents of fish, numerous miles down a river, to be found dead due to the toxins in the water. Carson states that the best way to eliminate a pest problem is to use natural predators, which are non-toxic, and a better long-term solution then pesticides, since many pests will become immune to most chemicals.

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

Many varieties of genetically engineered crops have been designed to decrease the need for chemicals, particularly pesticides. Herbicide-tolerant varieties are among the most widely used type of genetically-modified crop, which enables farmers to use a single herbicide to eradicate weeds rather than rely on a cocktail of pesticides and herbicides. Eliminating weeds in this fashion also decreases the need for soil tillage, which can negatively impact soil ecology. (Ford,

pesticides end up ruining the complete area and stripping it of the natural beauty of the land. The
