DDT

argument is that pesticides (she like to calls them “biocides”) have detrimental effects on the environment. She said that Dichloro Diphenyl Trichloroethane is harmful to bird populations and can be harmful to humans or even small to large animals. DDT is a chemical pesticide that is used for killing disease-carrying and crop-eating insects. (Pesticide action…

technologies, everything comes at a price no matter how little or small it may seem. For example, malaria carrying mosquitoes, were being eliminated by a designed toxin (DDT) however, the genetics of the mosquitoes had mutated. As a result, the disease was difficult to erase and more toxins were used to improve the outbreak. The DDT affected the food chain and integrated into the egg shells of birds causing a high bird mortality rate. As well, considering that the fact that mother nature is…

world that we live in. Rachel Carson mainly argued that pesticides have an adverse effect on our environment. She said that they are properly termed as “biocides” since their effects were hardly limited to targeting the pests. Carson spoke a lot about DDT as a prime example as well as other synthetic pesticides several that are subject to bioaccumulations. Carson has accused the chemical industries of spreading wrong information on purpose as well as how public officials then were uncritically…

crucial for agriculture. However, the use of these pesticides have brought more harm than good. Methoxychlor is a synthetic, organochlorine pesticide developed to replace dichlorophenyltrichloroethane (DDT) in 1948. It was preferred due to its low toxicity in mammals and shorter half life than that of DDT, thus decreasing its levels of persistence in the environment (Ye et al, 2014). Methoxychlor was used as an insecticide effective against a wide range of pests and was used on field crops,…

In the book Silent Spring, by Rachel Carson the thesis was that pesticides were harming the environment and wildlife, especially birds. Carson focused her attention on the pesticide DDT, which was first made in 1874. DDT was used heavily during World War II to try and control the diseases typhus and malaria. So she presented research that pesticides can cause cancers, other ill effects and how they can gather in animals bodies through a process called bioaccumulation. Rachel Carson was a…

Written in 1962, Silent Spring by Rachel Carson was one of the most influential texts of the environmental movement in the 1960’s and on. The book reported the adverse effects of pesticides in the environment and what our society could do to dampen the flame. Carson divided her book into seventeen chapters, each of which is an independent essay of its own, nonetheless the chapters fuse together to create a continuous non-fiction novel. In the first chapter, Carson provides the reader with a…

Rachel Carson’s Report: The use of chemicals as pesticides was not as prominent as it was in the 1960s when it was diligently sprayed by civilians in almost everything. From crops to insects to birds, everything was contaminated with chemicals such as DDT. One certain marine biologist and writer, Rachel Carson, decided to reveal the heavy truth about the effects of chemicals in her book: The Silent Spring (in particular-Chapter 2). The Silent Spring is an investigative journal concerning the…

against what was accepted as truth. The controversy surrounding her was and is largely because of the assertions she made in her most widely read book, Silent Spring. It proposed the -then radical- idea that pesticides, especially the commonly used DDT, had profound effects on our environment and should be used with reserve. It cautions that many pesticide’s abilities to reduce populations are not limited to insects and that a more accurate name for pesticides would be biocides. The book…

Though the information on environmental concern and the effect of pesticides (especially DDTs) were already available to the public, Carson’s book was unique in that it synthesized all the information in a comprehensive accessible way. She pieced together environmental concerns of urban and industrial reforms with the ecological issues that…

why is because its telling you all about the different chemicals and how they can harm the environment. The author had said that we use to use these chemicals, such as DDT, PCB, 2,4,5-T and lead And probably a lot more. The chemicals we use to use were very dangerous. People use to use them on there lawns. Farmers also used DDT to keep the bugs away from there animals and crops. the insects soon trembled and died. Fish turned belly up in the streams. Frogs and other amphibians were killed.…
