DDT

chemical pesticides during that time (Introduction). She believes that citizens must have the right to “be secure in his own home against the intrusion of poisons applied by other persons” (p xv under Introduction). In the face of obvious toxic effects of DDT and other chemicals, she reports that at the time, new chemicals were being introduced at the rate of 500 per year. (p 7). Thus, Carson coins the term “biocides” due to pesticides and insecticides’ effects to the environment and the circle…

Then, in 1947, the U.S. government declared war on mosquitoes. The main weapon? A powerful insecticide called DDT, which kills mosquitoes and other pests. More than 4 million homes in the South were sprayed with DDT. Airplanes dropped it over swamps and other wet areas. SOme people use ot in their homes and even doused there skin with it. DDT worked well-so well that by 1949, malara was no longer a health issue in the U.S. Today, is someone in the U.S. gets malaria, he or she…

The episode “Deadly Messengers” in the video series, RX For Survival, shows the deadly diseases transmitted to people by mosquitos and black flies. The mosquitos served as transmitters to deadly diseases like the West Nile Virus, Yellow Fever and Malaria. Another insect born disease was River blindness, which was transmitted through tiny black flies. The video also shares how public health professionals helped the targeted populations reduce the risk of coming into contact with mosquitos as well…

DDT, introduced as a pesticide shortly after WWII, as well as shooting and habitat loss, almost eradicated the bald eagle. Fish eating birds were most affected by the chemical, as it thinned the eggshells, causing eggs to shatter under the weight of their parents while being incubated or break while they were being laid. The DDT, originally in a low concentration, was concentrated by bioaccumulation, ensuring that the birds had a large amount of DDT in their diets. Other additions…

In my expert reports for the Fox and Kalamazoo matters, submitted in 2009 and 2015 respectively, I concluded that the weight of evidence prior to the time when NCR eliminated the substance from the paper did not indicate potential environmental hazards posed by the Aroclor 1242 in NCR CCP. I found that it was not credible to suggest that a company such as NCR had sufficient knowledge to be concerned about using a substance such as Aroclor 1242 in its CCP, especially in the absence of…

During the 1940s powerful chemicals, such as DDT were used to remove crop-destroying insects. In Rachel Carson’s “The Obligation to Endure”, she argues that harmful chemicals are not only killing insects but also modifying its surroundings(604, par.1). She develops this argument using poignant diction, explaining that the environment take milleniums to adjust and that human pollution is advancing further than the Earth can keep up thus causing irreversible damages to the environment. Carson’s…

to inform the American society about the dangers of a specific pesticide known as DDT. Carson describes many environmental impacts that coincide with the widespread spraying of DDT in the United States, questioning the logic of the large use of this chemical without completely understanding the environmental and human complications that could potentially arise. Throughout, “Silent Spring” it is illustrated how DDT entered the food chain and then began accumulating into the tissues of animals…

Vaccines and Autism Andrew Wakefield, a British gastroenterologist caused a widespread panic with a now vastly discredited and retracted paper from 1998 that linked the measles, mumps, and rubella (MMR) vaccine and autism. Since his paper, there has been a ton of scientifically unsupported theories linking vaccines and autism. Many parents also stopped vaccinating their children as a result (Gross, 2016). In 2011, Dr. Mercola published an article titled How to Help Eliminate the Hidden Enemy…

Spring was panned as a controversial, a criticism because sides of the argument as a scientist were not presented. Criticizers claimed that she should have include the pros and cons of widespread pesticide usage. Unfortunately, she was wrong about DDT and subsequently the error costed millions…

The goals of the Rockefeller Foundation and Soper had shifted – whereas the Rockefeller Foundation emphasized vaccination, Soper felt eradication was only possible with the elimination of the vector. Despite this difference, Soper’s efforts in Brazil were lasting and between 1930 and 1949, Brazil spent $26 million on yellow fever work (in addition to the prior $14 million spent by the RF over 28 years). Stepan is skeptical of the effectiveness of such large investments in the fight against a…
