DDT is commonly used to combat malaria in sub Saharan African homes where malaria is a huge contributing factor in the obituaries. Killing mostly Children and the Elderly this disease has stopped many bright minds from ever existing. Malaria occurs because an engorged female mosquito lands on a victim and then begins to draw/suck the blood out of them. When they are carrying the disease in the old blood in their stomachs they lose a little bit back into the victim when they withdraw their proboscis and if the blood that you get is infected you can get malaria. In 2006 the WHO reversed a 30 year old policy to begin the spraying of DDT in Africa. "Indoor residual spraying with DDT and other insecticides will again play a major role in [WHO's] efforts to fight the disease." Arata Kochi, director of the organization's malaria department, said at a news conference in Washington. "WHO will use every possible and safe method to control malaria." One application in a home costs about $5.00 and most of that is labor. DDT helped the malaria outbreak in North America as well as in Asia and North Korea. John M. Balbus [WHO] had this to say, "Given the severity of the malaria epidemic now in Africa, it is reasonable to be using limited amounts of DDT for indoor use, DDT is not the single answer, but it can be part of the solution until we find a better alternative." The WHO Okaying the use of DDT in Africa has sparked many controversies. The two options are those who urge DDT because it’s not harmful to humans and those who are against it because of the environmental effects. On ScienceHeroes.com they are saying that the environmentalists who are pushing to ban the use of DDT have practically won the battle. However, DDT use is still going on in Africa. On average about 800,000 people a year die from malaria in Africa. Sri Lanka is just an example of what

    Agriculture was first started around the year 8,000 B.C.E. in Mesopotamia. There the plants grew along with food so humans could eat them. These first parts of farming faced many challenges with insects and pests eating away their crops. During the era of 1000 B.C.E. the Chinese began experimenting with elements such as mercury and other compounds to contain the insects. Other civilizations would use chemicals to contain pests. The usage of chemicals has occupied agriculture, and even more recently in the 1940’s inorganic substances composed of various elements were heavily used to contain the insects affecting the crops. The growth of many synthetic pesticides occurred during this time, the most common one was DDT. DDT was used the most…

    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.…

    Malaria in Tanzania effects it’s country economically, socially and environmentally, but by taking the right steps, Malaria can be cured. Malaria is a widespread disease in Africa that is transmitted by the bite of a female mosquito. Malaria impacts a human physically, mentally and emotionally. Symptoms include a headache, fever, fatigue, dry cough, spleen enlargement and continuous vomiting. In Tanzania, approximately 93.7 out of 1000 people die of Malaria each year. NCBI.com states “There are 14-18 million cases of Malaria each year in Tanzania.”3 90% of the population is at risk. Therefore only 10% of the population is safe, but since the cases reported each year are increasing, that 10% will become a part of that 90% meaning the entire population of Tanzania can be affected by Malaria. This disease results in missed school and work days, and an overall loss of productivity. More importantly, the disease causes a negative economic impact, costing Tanzania 240$ million dollars per year.…

    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…

    Individuals living in climates that support the life cycle of these mosquitoes are more at risk than those who do not. If temperatures fall below 68 degrees Fahrenheit the mosquitoes cannot complete their growth cycle. Africa, parts of South America and Asia have incurred the majority of the malaria epidemic (Global Health - Division of Parasitic Diseases , 2010). I this paper I will cover: populations vulnerable to malaria, factors that make these populations vulnerable, modes of transmission, methods used to control the spread of malaria, the role of social/cultural influences and share community health promotion and wellness strategies.…

    Rachel Carson revealed the dangers imposed by indiscriminate pesticide use in her 1962 book, Silent Spring. Although Carson used DDT as her focus, the chemical was an example of the numerous synthesized pesticides employed in many aspects of mankind’s daily lives. As a biologist with the U. S. Fish and Wildlife Service, Carson was alerted to the “numerous case reports of damage to birds and fish after DDT application” and believed that “because DDT was so effective, it unbalanced ecosystems” (Oreskes (2010) page 219). Carson expanded her research and eventually published her revealing book to alert the public and bring an end to indiscriminate use. The book made numerous claims against pesticides, illustrated the destruction caused by prior use and warned of a future in which “over increasingly large areas… spring comes unheralded by the return of the birds, and the early mornings are strangely silent where once they were filled with the beauty of bird song” (Carson (1962) page 88).…

    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…

    During her scientific research, Carson discovered that people were misusing pesticides to kill insects that caused much damage. She became aware of the harm that people were doing to earth and all the living things. Some scientists came up with powerful chemicals that would kill insects effectively. One of them was called DDT. "Their pesticides effectiveness in controlling insects was unchallenged, but many scientists and ecologists became increasingly concerned about the indiscriminate use of the chemicals, whose poisons affected not only pests but also many other life forms, including humans." (Carson "Elixirs," 8) People would spray those chemicals everywhere it was possible because they thought it was harmless to them but helpful to get rid of all the insects that were causing some damage, yet…
