Rachel Carson‚ a renowned environmentalist‚ wrote this book to express her concerns over the human abuse of the environment. In this work‚ Carson vividly expresses and documents how the use of pesticides in agriculture indiscriminately affects the natural environment. She primarily focuses on how

especially many chlorinated hydrocarbons that are used as pesticides. Common chlorinated hydrocarbons include DDT‚ dieldrin‚ and PCBs. These chemicals are insoluble in water‚ but highly soluble in organic solvents like animal fats and plant oils. Due to their insolubility‚ they are persistent in the environment and cannot be broken down by any natural processes.

It goes in to detail about widespread use of DDT and our desire to have a “chemically sterile‚ insect-free world”. She notes that for the first time in history‚ humans were being subjected to enormous amounts of chemicals and poisonous substances and they had been recovered from most of the major

ENG 102 22 April 2013 Environmental Issues Today Rachel Carson had a passionate belief that mankind had launched a personal war on itself inadvertently due to the war it had launched on insects and its insistence of contaminating the air‚ land and water by doing so. At a rate of more than 500 new chemicals per year‚ of which 200 from the1940 ’s to the 1960 ’s were pesticides‚ the public market is flooded with more pesticides than it knows what to do with. More often than not‚ each new insecticide

It also symbolizes the first victory of change agents‚ because ten years later the United States of America will forbid the DDT (Hodgson‚ 2010). Gradually‚ the conservation movement developed in importance and lead to a ban of certain pesticides in the United States of America (Online ethnic centre‚ 2010). As a result‚ we can say that Carson’s text triggered the birth of the

types of widely used pesticide organic phosphates and chlorinated hydrocarbons. Chlorinated hydrocarbons consist of DDT‚ dieldrin‚ aldrin‚ chlordane‚ hexachlor‚ lindane‚ and heptachlor; in the 1950’s through 1960’s these were commonly applied to vast tracts of land in hopes to improve farming by eliminating plant-consuming insects. The legal supposedly safe amount was one pound of DDT per acre or one part per million but it was concentrated as it was moving up the food chain and metabolized. It

was used to regulate insect populations and increase crop yield. DDT was used by the military‚ government‚ cities‚ and even residents for gardens‚ suburb insect control‚ and to battle malaria. All its intentions seemed fantastic; no more bugs in a homeowner’s community‚ deadly diseases were beginning to become eradicated‚ and the production of crops was going to become exponentially higher. There was baggage attached to the use of DDT; it was extremely toxic to the Earth‚ animals‚ plants‚ and it was

and commercial pesticide use are long from over. Carson’s book described numerous environmental impacts of indiscriminate spraying of DDT in the United States and questioned the logic of releasing large amounts of chemicals into the environment without understanding their effects on the environment or human health. Her book facilitated the ban of the pesticide DDT in 1972 in the United States and the creation of the Environmental Protection Agency. Through her masterpiece Silent Spring‚ she accused

decade there has been a tremendous increase in the yields of various crops to meet the demand of overgrowing population‚ achieved by using pesticides and insecticides. These are chemicals that are sprayed over crop to protect it from pests.

It uses extraordinary rhetoric and accurate scientific accounts to confront the dangerous use of insecticides such as DDT and the negative impact that they have on humans and the surrounding environment. While there are countering viewpoints that believe that the benefits of using insecticides like DDT outweigh the negative affects they can have‚ I believe that the main essence that Carson was trying to portray‚ which is that these man made chemicals can be
