Dichlorodiphenyltrichloroethane: Pros And Cons

As time changes and the human population begin to grow, we get the idea of faster and cheaper to keep the world satisfied. In the mid 20th century a revolution occurred called the Green Revolution. This revolution came about because humans wanted a way to supply enough food for the growing human population by dramatically changing the field of agriculture forever.

The Green Revolution was a period when agriculture yield increased due to new advances and chemicals. One advance was chemical fertilizer, theses fertilizers was able to supply crops with extra nutrients and increase the yield. Not only does adding chemical fertilizer to the soil keeps the land productive by replenishing the depleted nutrients, it also help plants fight off diseases,

Both of these chemicals have their pros and cons. These chemicals were able to control unwanted weeds, kill insects, prevent diseases, and also created a higher productivity. By using pesticides on crops, humans are being exposed to low levels of pesticides residues through their diets. This is a problem because children are facing neurodevelopment effects. One of the most known pesticides is Dichlorodiphenyltrichloroethane (DDT). This chemical was first introduced in1874 by a chemist named Zeidler. It was used for insect control in the United States but was canceled in 1972 by the EPA. Before the chemical was banned it was used on food crops like beans, cotton, soybeans, sweat potatoes and tomatoes. It was also used for pest control. Everyone wanted DDT mainly because it was effective, inexpensive and persist in the

This term shows a situation in which it becomes necessary for farmers to increase the use of pesticides because they are trapped in an everlasting agriculture cycle. The treadmill works by a farmer spraying their crops with a pesticide and the pesticide is no longer effective, the farmer will then try a more toxic chemical and increase the dose so the new pesticide can be more effective and the cycle continues. As the treadmill escalates, the pest that the farmer was trying to eliminate could cause another pest to thrive resulting in the farmer to have to use another insecticide to eliminate the new pest problem. This can lead to more pests and the need for more
