According to this
The purpose of this thesis is to remind readers of the nature of spring, which was before the introduction of pesticides. The name was aimed at seeing “silent spring” without “birds”, since all birds were excluded from the pesticides used. Poems. “
Carson made it clear that she was not a proponents of the ban on pesticides. Instead, it advocates the right and responsible treatment and use of pesticides. People should be informed about how pesticides take place in their own environment. Through various case studies, it explains how the chemical pesticide has a negative impact on the environment. It also provides cases where organisms have been affected by chemicals in ill-treatment
These problems were due to the fact that the country paid more attention to economic growth, as well as to the benefits of increased agricultural production, without paying attention to the negative consequences that might arise
Pesticides refer to chemical or biological substances that have destroyed, controlled or destroyed some plants or animals that have damaged the necessary organism. There are two main categories of pesticides that humans use to control pests. These are organic and synthetic pesticides. Dichloro-dipheny-trichloror-ethane (DDT) refers to popular synthetic pesticides. This is classified as a chemical known as chlorinated hydrocarbons. Although extremely dangerous, it is used to destroy insects, and its effects are not immediately implemented. It has long-term effects because it passes through food chains
This means that once it can affect organisms that it has not sprayed directly. Dieldrin, aldrin, chloride
Once the pesticide DDT has been introduced into the environment, the pesticide and its persistence determine the level of harm that it may cause to other organisms that have not been distributed by the user. Most pesticides used are not degradable. Thus, they infiltrate the soil after they have been despicable in the water, and then they harm the organisms that they’re communicating with. Aquatic organisms and those living in the soil are the most affected. Many people believed that DDT was harmless, because in what form it was used, its consequences were not an instant. However, the main enzyme enzyme is prohibited by the active ingredient in the DDT. The accumulation of this pesticide in the body results in harmful effects that eventually pass through the food chain of animals
The DDT may also move through placenta to affect unborn children or animals after parents contact him. It also affects vertebrates, as they are mostly worms. High quantity of DDT was used for sprays of trees. The earthworms ate and euthanate the leaves that fell with this chemical, the birds fed on these warheads, and so they acquired the chemical. There were also birds that ate insects on trees that already had this chemical substance. Most farmers use insecticides in their farms, and they affect fish in ponds. This is because the chemicals are washed out from the trees in the rain and the sediment in the ponds and in other waters
These chemicals also affect people. Most of the field staff were affected by the DDT. Cancer was one of the effects of the DDT for both adults and children. People were consuming these chemicals through the skin. Rachel Carson has conducted an extensive environmental study before writing this thesis. Her dissertation presented the basic ecological concepts in America. Just as in the case of failure to pay attention to the various problems Carson was talking about? How has the effectiveness of governance been limited to this relationship or how has it produced counterproductiveness?
In the last chapter, “Another Road”, Carson offers alternatives that humans can use to save organisms from chemical pesticides. The best alternatives proposed by Carson are biological controls. This is because the use of biological controls is simple. They are also safe for humans and animals, effective and cheap. Biological controls work in natural rules. They don’t have an insect predator. In addition, they do not affect the environment and habitat of their target insects. There are also biological controls that can sterilize insects
Inspiration, similar to what Carson does in his dissertation, is very important in the modern world. Given current technological progress, people simply use pesticides without taking into account their effects on them and the environment. Cancer is a disease that affects adults and children. Buildup of chemicals in the body may be one of the causes of cancer in modern society, but people use chemicals irresisously
Biological controls were typically used in the past, but they were phased out when chemical methods appeared. That’s because people wanted to know if they were effective. Almost the entire population now uses chemical methods, and this is becoming problematic. This is because, even in the case of the danger posed by these chemicals, humans continue to use them and use biological methods to control pests, which appear to be difficult for most people
