The Negative Effect of Pesticides on the Environment 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.
The nutrients do not come back to the soil until the crop decomposes so when you add fertilizer, the process is sped up and plants grow faster. The question is asks if the use of chemical fertilizer is bad for crops. Our group argues yes. Yes, chemical fertilizer is bad for crops and the environment around it too. Our first reason is that chemical fertilizers contain many elements that are bad for crops.
The food given to these animals are supposed to make them grow faster, but it is also causing serious digestive problems for the animals. According to the Sustainable Table, “recent studies have shown that chemical additives in feed may accumulate in animal tissues, potentially exposing consumers to unwanted chemicals such as veterinary drug residues and heavy metals.” This is not fair for the animals and humans to have to suffer through something like this just so unhealthy food can be produced. Environmental Impact of Unsustainable Foods One of the big problems that came along with unsustainable foods is its terrible impact on the environment. The factory farms that have produced these unsustainable foods have caused a lot of pollution.
Modern agriculture has also benefited from this new technology. Of course if pesticides were regulated things may run a bit more smoothly, however, once regulated there runs the risk of not enough pesticides being used and certain species either adapting or becoming more dominent with their predators diminishing. Perhaps even more bacteria would be produced should pesticides be used less. We could end up facing a new age of nature’s baterial and viral weaponry that we simply cannot afford to face.
Remembering that these compounds were once used as a chemical war agent, the adverse affects of the anti-cholinesterase inhibiting pesticides are varied and extreme at acute and accumulating doses. The delicate balance of chemistry within the biological system must be maintained or the previously mentioned range of symptoms can occur. However the use of OPs remains high even despite advances being made in new classes of pesticides. With little or no control over agricultural use of pesticides, home consumers should be aware that many insects can be managed without insecticides. Physical removal, biological and organic control, and sanitation can eliminate most home and garden pests.
Both affect each other in many ways. For example, continues use of fertilizers currently causes of greenhouse emissions. This environmental problem can affect the agricultural field, because high concentration of carbon dioxide cause the leaf pore shrink and diminishing tree cooling power, this will resulting in decreasing crop production and at the same time global warming phenomenon. Besides, agriculture also has both harmful and beneficial effects on the environment by changing the quality and quantity of soil, water, air, biodiversity and landscapes. Farming is currently a main source of water pollution.
Chemicals are constantly being developed or improved to enhance the competitiveness and adaptability of crops, and to kill the parasites and weeds which plague the agricultural sector. . This however is not always good as the plant and the pests then become resistant to these new chemicals defeating the purpose of it being used. The new chemicals which are produced to kill these strong pests and weeds may be more harmful to other plants and remove nutrients within the soil in turn reducing the yield of agricultural crops. The benefits of these characteristics are seen in Argentina according to Pelletier (2010) as they use glyphosphate resistant soybean which allowed the comeback of this crop, as the so... ... middle of paper ... ...9).
Chemical Water Pollution Many industries and farmers work with chemicals that are dumped into water. These include chemicals that are used to control weeds, insects and pests. Metals and solvents from industries can pollute the sources of water. These chemicals are poisonous to the living organisms in water and may slow their growth, make them sterile and can kill them. 8.
The United States relies heavily on pesticide to meet the nation’s food demand. Pesticides eradicate pests by giving a bad taste to the produce, or causing a disease. This can affect humans, however (Huff). Because of constant spray usage, natural selection causes the pests to become more and more resistant with the passing years. The harmful effects on the environment and humans are usually irreversible, and life-long.
As pesticides are extremely complex and created to often destroy weeds and bugs, they also can affect plants, ecosystems, and animals. Because pesticides are insanely toxic to animal environments and humans, alternative ways to prevent bugs and weeds must be executed. With the growth of demand on crops, farmers want to maximize their crop’s outcome. Because of pests and parasites, countless crops were destroyed and were deemed inedible. Since farming was initially used, people have tried to discover ways to prevent this.
