DDT VS. Malaria

Observation and Background information

Malaria is a disease that is in the blood; it comes from the plasmodium parasite. Malaria is carried from a mosquito to person then it spreads from person to person. (Kar,N) There are over a hundred species with malaria parasite that are highly populated in Africa these parasites are called Plasmodium falciparum. (Kar,N) when a parasite gets into a humans system it finds its way in the liver where it creates approximately ten thousand more. (Kar,N) Female mosquitos transmit malaria. (Kar,N) Two weeks in the body parasite move into the blood stream where it starts messing up the red blood cells. (Kar,N) It usually takes 10 days to four weeks after …show more content…

(NPIC) Years down the line a scientist named Mueller also discovered DDT in 1939. (NPIC) DDT was a well-known pesticide used to control insects in the United States until it was canceled in 1972 by the United States Environmental Protection Agency. (NPIC) People that served the military at the time of World War II used DDT for public health purposes. DDT was used to control all of the following malaria, typhus, body lice, and bubonic plague. (NPIC) DDT is still available to be legally produced in the United States, it can only be sold and used by foreign countries. …show more content…

(Dyson, J) DDT is toxic to birds when ingested. (NPIC) I would rather for the insects to be killed instead of malaria getting out of hand and killing humans. The World Health Organization estimates that there are 300 to 500 million cases of malaria each year and around one million deaths. (Dyson, J) These numbers are going up to 20 percent a year in some areas. (Dyson, J) Its been proven that when countries quit using DDT malaria gets out of hand. (Dyson, J)
DDT has been proven to lower the number of malaria caused deaths. For example India’s malaria of 800 000 a year death rate was cut to zero by the late 1960s. In Sri Lanka DDT was reduced to 2.8 million cases a year to just 17. (Dyson, J) The US National Academy of Sciences in 1970 stated that DDT had prevented millions of deaths that would have been inevitable. Small amounts of DDT can affect small microorganisms. (Duke.edu) DDT microorganisms don’t usually die, they tend to keep the DDT in themselves this makes it bad for those predators who eat these organisms.

    By the name of “superspecies” we try to change the world feature and control the nature with science. With science, a lot of technology has been invented to support people demand for products. Without anticipation about the bad consequences, sometime the invention is causing more damaged than it provide in later on. In 1930, DDT that use for killing insect was discovered by Paul Mueller, working for the chemical company Geigy in Switzerland. For this reason, the benefits of using DDT became immediately obvious (65). Years letter, the unbelievable side effect of using DDT was found. While Biologists investigated the decline of eagles and hawks, they discovered the hitherto phenomenon of “biomagnification”, which compounds gather as they are ingested up the food chain (67). DDT phenomenon proves that thinking like science is only to understand the world in separate pieces. It is lack of understanding the rhythms, patterns and cycles of the nature. Therefore, we need to think beyond the science to see the connections between us and nature because in the reality this world is the world of

    The Baby Boomer generation and the time period has a lasting effect on the economy and the environment. The baby boom for the United States was similar to other countries after World War II. Several economies also blossomed, but overall with very little care for the environment. After World War II the use of industrial made chemicals increased in popularity throughout the United States and the world (The “New Environmentalism” OF THE 1960S). The chemical DDT was originally being used widespread to eradicate disease vectors, such as mosquito carrying Malaria ("The DDT Story."). DDT influenced more than just mosquitoes as it had lasting effects in the environment where it noticeably bioaccumulate in the food chain and caused high mortality in young bald eagles ("The DDT Story."). Rachel Carson’s book, Silent Spring released to the public in 1962 which is the time period in which environmental health and human health were connected (The “New

    The documentary about DDT and Silent Spring is really sad. DDT is an innovation that was seen positive by the public yet they did not studied about it hard enough to find out what will the effects of it will do. At first I saw a positive light about it because it is said to help farmers and neighborhoods kill pests. It really does kill the pests but it has effects to all life forms too.

    In his short story, “Top of the Food Chain”, T.C. Boyle effectively argues that humans are destroying their planet with chemicals and that the general consensus of the public is that it is okay. He argues this efficaciously through the use of rhetorical and satirical devices, which are used throughout his story. Overall, I agree with Boyle’s argument that DDT is an especially harmful chemical to our planet, and while it may have had a place at one time, there is no need for it any longer.

    The history of life on earth could be thought of as a record of living things interacting with their surroundings; for most of history, this has meant that life molds over time by the environment it inhabits; however, very recently, humans have become capable of altering the environment in significant ways (Carson 49). Marine Biologist, Rachel Carson, in her environmental sciences book, The Silent Spring, documents the detrimental effects on the environment by the indiscriminate use of pesticides. Carson argues vigilantly in an attempt to persuade her extremely diverse and expansive global audience, under the impression that chemicals, such as DDT, were safe for their health, that pesticides are in fact detrimental for their health. Through

    When it comes to pesticides in this book it is clear that they are harmful to the environment and humanity when not used properly. Carson describes the importance of this issue and pushed for the improvement of the system. She proposes multiple solutions in order to keep the people and animals safe while getting rid of the insects that have become an annoyance. As a writer and researcher Carson is passionate and determined to find out new ways of solving the problem at hand. Unlike the rest of the people in the book, Carson takes the more educated and logical approach to prove her point that what they have chosen as a solution is not affective and actually more destructive for the environment. She does her research which shows that the pesticides are having negative effects on many aspects in nature.

    It is caused by parasites of the Plasmodium species(in text reference). These parasites are carried by mosquitoes which become infected after biting someone who has malaria. Malaria is then passed on to others when the infected mosquito bites another person. In rare cases malaria can be passed to another person through blood transfusions, organ donations or shared needles.

    However, after the war DDT was used by farmers in the U.S. and all over the world to ward off pest from their crops. DDT heavily affects wildlife in many ways. In a recent report that I did on the Bald Eagle, I discovered that DDT played a huge role as to why the Bald Eagle was listed on the Endangered Species list in 1967. It was discovered that DDT accumulates in fatty tissues and impairs the egg formation, making them thinner then normal, causing a decline in reproduction. This was not only the case for the Bald Eagle but also for a numerous amounts of other birds. Not only does DDT have an affect on birds but other mammals by attacking the nervous system and attacks aquatic life at the plasma membrane says Cruising Chemistry, a website used by Duke University. Throughout “ Silent Springs “ Carson gives multiple examples of the unpredicted dangers of DDT. One example is when she discusses a real problem that occurred at Michigan State University

    Malaria in humans is caused by four species of protozoa, sophisticated one-celled organisms, that can infect red blood cells. These four species are called Plasmodium falciparum, plasmodium vivax, plasmodium malariae, and plasmodium ovale. The worst cases are caused by the Plasmodium falciparum species, which is also the species with the most resistance to drugs. To contract malaria, a mosquito, but not just any mosquito must bite a human. The only type of mosquito that can infect humans with the malaria virus is the Anopheles mosquito. While there are...

    And when I say that it can benefit plants, I mean that it helps growing crops, curing diseases, and can be used often because it is cheap. Now I will tell you how DDT is beneficial. One of the ways DDT is beneficial to use humans is because it cures diseases. From the article “Typhus” it says “DDT comes in a form of a vaccine and helps cure typhus.”

    While the lasting impacts of POPs have yet to be fully understood, scientists do know that the widespread use of POPs in the mid-twentieth century continue to impact the environment today. (Travelling Toxics) Emily Carson began her studies of pesticides and insecticides in the early 1950s and found residues of chemicals lingering in soil where they were applied dozens of years before. (Elixirs of Death) Additionally, it was as early as 1950 that scientists of the Food and Drug Administration declared that it is “extremely likely the potential hazard of DDT has been underestimated.” (Elixirs of Death) The results of both of these findings were that the negative the impacts of the accumulation of POPs first became apparent, however, there was nothing done to address the problem until much later. (Travelling Toxics) As a result, the environmental destruction only increased, until reaching a contamination peak in the 1970s. (travelling toxics) An early example of the destruction caused by POPs was found in Canada’s North in 1988, where scientists found elevated levels of polychlorinated biphenyl (PCB) and dichlorodiphenyltrichloroethane (DDT) in wildlife and humans. (Changing environment, changing times) Women from Broughton Island, the North West Territories and northern Quebec were found to have five times the levels
