DDT
The use of the chemical, dichloro-diphenyl-trichloroethane (DDT), is a prime example of how public health benefits and environmental costs tradeoff. DDT was extensively used worldwide beginning in the 1940’s as a means to kill insects; it was also used to prevent malaria from spreading and control agriculture pests. DDT became so popular that at one point the U.S. was the leading producer, developing thousands of metric tons of DDT. With years of scientific research, researches came to find that effects of DDT were a serious threat. In return, as Kathleen Walker from the U.S. Environmental Protection Agency and Marie D. Ricciardone and Janice Jensen from the U.S. Department of State report in the International Journal of Hygiene and Environmental Health, the United States alongside ninety-one countries signed the Stockholm Convention on Persistent Organic Pollutants (POPs) on May 23, 2001, “thereby pledging their commitment to protect human health and the environment from 12 toxic chemicals of global concern”( 1); DDT was one of the twelve hazardous chemicals designated by the Stockholm Convention. By the 1970s, the EPA cancelled all use of DDT on crops in the U.S. In 1972, the United States and ninety one other countries banned use of DDT. The illegalization of DDT was a crucial safety measure that ensured the prevention of harmful effects caused by DDT. To fully understand why the global ban came to be, a discussion of DDT’s historical background including empirical examples of DDT use is necessary. An understanding of the chemical properties followed by the long term effects of DDT on both the environment and humans will help explain why controlling DDT use became a top priority. Swiss entomologist, Dr. Paul Muller, won the noble prize in 1939 for being the first to discover the effectiveness of DDT to kill insects, even though the existence of DDT dates back to the nineteenth century. The use of DDT during World War II prevented insect-spread epidemics

    The Silent Spring was the right science book published at the right time. It brought the concerns about environmental to the general public. It led to a nationwide ban on DDT and the creation of the U.S Environmental Protection Agency. DDT’s insecticidal action was discovered by the Swiss chemist in 1939 ("DDT"). The widely use in agricultural started after the World War II. The Swiss chemist was even awarded the Nobel Prize since DDT was so efficiency to kill inserts. Nevertheless people did not notice that DDT was also a great threat to the environmental and wildlife especially birds. People like to talk about sustainable development in recent years; DDT is a great counter example of it. Although it is very efficiency to kill inserts, it…

    4. The ingestion and accumulation of DDT and other insecticides even when foods directly treated with these chemicals are avoided is possible because it can be present as tiny residue on foodstuffs that was not necessarily injected. DDT and other insecticides are passed on from one organism to another through all the links of the food chains and can also be passed on from mother to offspring. Storage at low levels then makes these chemicals a threat that is able to persist for a long time.…

    Unlike most pesticides, DDT is not limited to destroy just 1 or 2 different types of insects. It kills hundreds. In 1945 DDT became accessible to the general public, however just a few of individuals who were able to draw distinctive conclusions about this new wonder compound. The first being author Edwin Way Teale, who cautioned, "A shower as unpredictable as DDT can agitate the economy of nature as much as a transformation upsets social economy. Ninety percent of all insects are great, and in the event that they are killed, natures balance is altered.…

    Pesticides are widely used in modern agriculture in order to increase crop yields by inhibiting predation and competition (Berkley). Large corporations have flourished under the demand for more affective pesticides and have in result developed stronger and more effective pesticides. In their race for wealth and influence is it possible that the greater good of man and an outlook for a sustainable future was overlooked? Could these companies have developed products that, used abusively will wreak havoc on natural ecosystems? Through this paper different aspects of pesticides, with a focus on Monsanto’s Roundup® will be assessed on their effects on the environment. Impact will be weighed and a conclusion will be drawn on the use of pesticides such as Monsanto’s Roundup’s overall negative effect in…

    This entry focuses mainly on the chemical DDT, which is over consumed on various vegetation, however, the overall idea is regarding our environment and how human actions are abolishing it, although it may be unintentional. To be more specific, the central idea consists of the environmental actions that are backfiring on our population in a negative way. Furthermore, in my opinion, Rachel Carson desires to spread awareness about the harmful deeds that are destroying our environment and our society’s health.…

    The book, Silent Spring, by Rachel Carson is regarded as the most significant environmental novel as it was the start of the environmental movement. This book highlights the human poisoning of the biosphere through chemicals aimed at pests and disease control, particularly dichlorodiphenyltrichloroethane (DDT). DDT pesticides were particularly harmful because as they entered the biosphere, they not only killed the bugs but also entered the food chain. DDT accumulated in the fatty tissues of animals and humans which had potential to cause cancer and genetic damage. This also contaminated world food supply as DDT can enter any animal that we eat. Despite the immense effect of DDT some insects survived and passed on their resistance resulting in tougher descendants, so more toxic insecticides needed to be…

    It was the one of the first ever man-made insecticides that 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 also effecting humans…

    The DDT had also killed many of the wasps that killed the caterpillars that ate the wood on their houses. The caterpillars had nothing to stop them in taking down the palms provided shelter for the local people. This was disregarded because at least they got rid of the mosquitos and wasps. Even though the local people no longer had shelter and could not sleep. With all of these other things now taken care of the flies became the major issue causing more disease. The DDT was then sprayed on the ground to help take care of the problem. Of course it was not taken into account that cats ate geckos and geckos ate flies. No one had a concern about taking care of the flies until the cats started dying and the rat population grew and took over again creating new issues and…

    DDT is an organochlorine used for its properties as a pesticide. Following WWII, DDT was used widespread in agriculture in the United States. DDT, in the form of “sprays, dusts, and aerosols,” was “applied almost universally to farms, gardens, forests, and . . . [had] the power to kill every insect, the ‘good’ and the ‘bad.’” In 1962, Rachael Carson published Silent Spring in which she discusses the impact DDT usage had on the environment and public health. Even though “the intended target may be only a few weeds or insects,” it killed everything and left behind “a deadly film.” She insisted that DDT “not be called ‘insecticides,’ but ‘biocides’” due to its dangerous effects. For example, Carson correlates the use of the pesticide with cases of cancer and showed evidence to suggest that DDT was especially hazardous to bird populations. The chemical caused the shell of bird eggs to be thinner than normal, making them more fragile. Populations of Bald Eagles and certain species of hawks plummeted. In addition, Carson argued that DDT was “of concern to us all” and that “if we are going to live so intimately with these chemicals . . . we had better know something about their nature and their power.” A proper investigation of the long-term health effects of DDT was never carried out prior to the release of the chemical to the general public. Big industry responded to Carson by working to discredit her. They did not want to admit their mistake and take responsibility. DDT was ultimately banned in 1972 from agricultural use; however, the damage had already been…
