Recommended: Impact of malaria on people
Introduction
Nearly half a billion people are infected with malaria each year and more than a million people die from this disease. Malaria is transmitted through the bite of a female Anopheles mosquito infected with malaria parasites. When the parasites enter the human body, it slowly destroys the body’s red blood cells, eventually killing the patient if left without undergoing immediate treatment (Stanmeyer 2007). One of the means employed to counter the spread of malaria is through the use of DDT as an insecticide to kill the mosquitoes before they are able to infect more people.
DDT is an organochlorine insecticide that is absorbed through surface contact and kills by poisoning the nervous system (Pesticide Action Network UK 2012). It has become highly effective in combating insect-borne human diseases among military and civilian populations (U.S. Environmental Protection Agency 2011). Currently, through the Stockholm Convention, which was signed during the United Nations Environment Programme 2002, 12 chemicals have been banned, one of which is DDT. However, production and usage was granted to control disease vectors provided recommendations and guidelines of the World Health Organisation (WHO) were adhered to, until locally safe, effective and affordable alternatives were available (van den Berg 2009). Thus, this study is to investigate the effectiveness of the usage of DDT to combat malaria and addresses the controversies surrounding this method by looking at how it affects humans and the environment.

Can be used indoors for the prevention of mosquito breeding as wettable DDT powder can be mixed in water. This mixture is then sprayed through a compressed air sprayer and not applied as an...

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 pesticide DDT banned in 1987 was a detrimental to the environment leading to it to be banned in 1987. DDT remains in the soils for a long period of time. The chemicals affect the ecology of the soil and water run off causing contamination of livestock and native animals and aquatic species. Studies indicated a range of human health impacts from DDT including cancers, infertility, miscarriage and nervous system impairment. The social and economic impact of DDT use in viticulture was significant.
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
Early in history DDT was a very effective chemical that killed many parasites and stopped the mass spread of malaria. But the reward is not worth the damage that it does to the environment, especially in modern day where we have other ways to prevent parasite and diseases from getting to us. "Top of the Food Chain" by T. Coraghessan Boyle, is a story about the absolute absurdity of things that human beings do to their world and to their fellow living beings. Set during a Senate hearing by a chemical company executive on the defensive about the effects of DDT in Borneo. Basically, poison was used to get rid of mosquitoes. Didn't work. So they brought in geckos, that died from the poison. Cats ate dead geckos, and cats died. This brought on rat infestation. So they brought in more cats and cycle started over again. He is arguing that humans are wrong for destroying their planet with pesticides and other harmful things; this satirical piece effectively supports his argument.
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

In likeness to Aids, the malaria virus can be in your body for up to
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...
The use of pesticides such as DDT and PCBs that helped to reduce the population of harmful insects that plague fields before the 1970s. Nevertheless,
Each year, people all over the place begin their battle against the bugs, especially mosquitos who need blood to reproduce. Most people in warmer, wet climates spend a small fortune each year, trying to figure out how to eliminate these nasty, infection spreading, blood sucking, insects from their home and their lawns. Due to the fact that people hate them so much, there are numerous ideas on possible alternatives to bug spray that are cost effective. Most are things that we have in our homes anyway. For instance, the rumor is that Listerine works to repel mosquitos, but there are many who question whether it is true or false. Does Listerine repel mosquitoes? Here is the truth about Listerine for mosquitos.
In many countries, an effective mosquito repellent is the difference between life and death. Every sixty seconds a Child dies from a mosquito transmitted illness. Most of the alternatives used today are hazardous or outdated. The price for a quality mosquito repellent is far too expensive for the average consumer, purchasing repellents on a regular basis. Mosquitos can track a human’s carbon dioxide exhalation for up to the length of a 100 yard football field. The kite patch blocks the scent of carbon dioxide using natural, non-hazardous material protected the user for 48 hours. If the Kite patch can ...
Each year there are 10,000 pesticide related poisonings. On July 4th 1985, over 300 Californians became sick after eating watermelons treated with the pesticide tenik. Testing supermarket produce is a way of determining the amount of exposure the consumer receives through common produce like carrots, tomatoes and lettuce. 44% of foods that were tested in supermarkets were found to have some traces of pesticide residue on them. Of all the pesticides found, nineteen of them were a pesticide called DDT. DDT was banned in this country 12 years prior to the testing. It was believed that these chemicals might have entered this country from another country that doesn’t have pesticide restrictions as the U.S. does.
Frequency of application is defined as how often an insecticide is used that influence resistance development. Resistance can happen in many ways such as met...
“Ancient Romans killed insect pests by burning sulfur and controlled weeds with salt. In the 1600s, ants were controlled with mixtures of honey and arsenic. By the late nineteenth century, U.S. farmers were using copper acetoarsenite (Paris green),calcium arsenate, nicotine sulfate, and sulfur to control insect pests in field crops” (Delaplane, 1996). DDT was developed as the first modern synthetic insecticides in the 1940s. DDT was initially used to treat malaria, typhus, a...
