The Giant Sprayings

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.

Rain washes the pesticides that are used in our Australians households and then become run-off in drains and sewers. They then make their way into nearby water bodies, wether that be creeks, rivers or even oceans and settle within the soil by sticking to small particles, including tiny living organisms like phytoplankton (M. Barwick, 2003, pp. 471-502). Small fish consume these tiny organisms, which may then be eaten by a larger organism and this continues until the top order consumer is reached. The concentration that first began in the phytoplankton and has multiplied sufficiently as it moves along the food chain. The amount of the pesticide has reached a highly toxic level in the top order predator, whether that is birds or even humans. As a result of the biomagnification of pesticides and other chemical the marine environment and the organisms that live within it are heavily affected. The build up of heavy metals, for example, it interferes with the formation of red blood cells, creates liver and kidney implications and forms reproductive defects in many organisms. This hinders an organism’s ability to survive and reproduce and can create a decline in species

Some research studies show that these chemicals are also the cause of birth defects in children. With the increase in the use of these chemicals, there will be an increase in birth defects. According to research done by the University of California, pregnant mothers who live within a mile away from crops that are sprayed with pesticides are more likely to develop autism in their babies. If the use of pesticides continues to grow, one day the human race with completely diminish.

“The study proved that this type of pesticide is only transmitted through diet” (Parvin). Although this study focused on only one particular pesticide, many of the possible pesticides we ingest through non-organic foods are the result of farmers using these pesticides on their crops, which later are absorbed by the body, possibly causing damage through various bodily systems.

To understand pesticides, we must look at the facts about them. According to the EPA, pesticides are chemicals specifically designed and sold to prevent, destroy, or repel pests from garden, greenhouses, fields, and orchards (Learn About Chemicals Around Your House). Charlotte Gerber’s article, How Do Pesticides Kill Bugs, explained that pesticides targets insects and kills them by attacking the nervous system and then when the muscles are over-stimulated, this will lead to paralysis and death. The effect of the organophosphates that cause that in pesticides was discovered in the 1930's during World War II. They were used in the creation of nerve gas, which was used in chemical warfare. When used in lethal dosages for humans, organophosphates cause extreme excitability, convulsions, paralysis and in most cases, death (Gerber). According to Effects of Pesticides on Human Health, The World Health Organization estimates that there are 3 million cases of pesticide poisoning each year and up to 220,000 deaths, primarily in developing countries (Lah and Glibert 2011). Children, and any other young and developing organisms, are particularly vulnerable to the harmful effects of pesticides. Even very low levels of exposure during development may have adverse health effects. Exposure can even lead to neurological health effects such as memory loss, loss of

In the early 1940’s, a new technology emerged that was able to successfully combat crop-damaging and disease-carrying insects. A new age of synthetic chemical pesticides use arose. After their impressive success in fighting deadly insect-borne diseases during World War II, pesticides were used widely to combat insect pests for agriculture and public health. Few people challenged the benefits of the new scientific and technological products and many embraced pesticide use with enthusiasm. Despite its success, doubts about pesticide use began to appear a decade later in the 1950’s, when the government began a vigorous pesticide campaign across the country against insect pests. Scientists began reporting heavy losses of avian and

Over 500,000 people were exposed to toxic gas from a pesticide plant, leading to thousands of deaths and tens of thousands of injuries.

The higher the trophic level, the higher the concentration of toxins in the species. There may be a tiny bit of pesticide in a plant which is then eaten by a insect which is then eaten by a shrew. The shrew then gets more toxins, then giving the owl which is at the top of the food web the most toxins causing it to become sick and die. Overall, these pesticides in ecosystems can disturb food webs, ecosystems, and hurt

DDT and other chlorinated hydrocarbons are very fat soluble so when these chemicals are sprayed on plants and these plants get eaten by animal the chlorinated hydrocarbon gets in the animal's fat. Then that animal get eaten by another animal and now that has the chlorinated

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

Pesticides also have a great affect on the food we consume. Food is one of the great necessities of life. Yet, a growing amount of evidence indicates that the food supply is being contaminated with pesticides (Mott & Snyder vii). These pesticides are most commonly

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.

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