DDT Isn't Cool With Me Essay

It tropical and sub-tropical climates temperature, humidity, and rainfall work together to create a breeding ground for mosquitoes. Mosquitoes are a host for communicable diseases one in particular is called malaria. Malaria is a parasitic disease that infects a particular type of mosquito, Anopheles mosquitoes, which feeds on humans. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness. Although malaria can be a deadly disease, illness and death from malaria can usually be prevented (Global Health - Division of

DDT is a very controversial product… but why? DDT was a pesticide used in the 1950s and it was very effective at killing mosquitoes. This was good because mosquitoes carry a very deadly disease called malaria. But soon the government banned its use in the USA. It supposedly has been decreasing the populations of bald eagles. They think that it makes the eggshells thinner, so when the eagle it trying to keep the eggs warm it might break the eggs on accident. Many people are happy about this ban and others are not. Some researchers feel that evidence supports a ban on DDT while others feel that it is an over reaction to an environmental concern. DDT has been shown to help control the malaria parasite. Evidence supports the banning

Malaria (also called biduoterian fever, blackwater fever, falciparum malaria, plasmodium, Quartan malaria, and tertian malaria) is one of the most infectious and most common diseases in the world. This serious, sometimes-fatal disease is caused by a parasite that is carried by a certain species of mosquito called the Anopheles. It claims more lives every year than any other transmissible disease except tuberculosis. Every year, five hundred million adults and children (around nine percent of the world’s population) contract the disease and of these, one hundred million people die. Children are more susceptible to the disease than adults, and in Africa, where ninety percent of the world’s cases occur and where eighty percent of the cases

Malaria is spread by the female Anopheles mosquito.When the mosquito bites the malaria parasite is passed into the human bloodstream, infecting them and this works both ways, if a human has previously been given the parasite and a unaffected mosquito bites them, the mosquito will pick up the parasite and spread it further. For the mosquito to survive it the humidity must be high, and the temperature must be between 15°C and below 40°C. Stagnant pools of water allow the mosquito to live. It uses areas like marshes, lakes and river pools to breed. Increasing population growth can encourage people to live closer to affected areas that were previously avoided, such as close to river pools. Normally the

First off DDT has the ability to kill insects that carry diseases such as malaria. There is

1. DDT stands for Dichloro-Diphenyl-Trichloroethane. It was commonly used a pesticide and it was also one of the first chemicals used widespread all over the world. It was created and used to try and end malaria and other insect-borne human diseases, and it had great effects in doing so. Also, it was commonly used for control in livestock production in agricultural areas. Although the broad use of DDT worked effectively in achieving the goal to slow down malaria, it created many controversies about the use of the common pesticide.

Dichlorodiphenyltrichloroethane (DDT) is an extremely powerful contact insecticide that has a high toxicity. It can be swallowed or pass in through the epidermis, also known as the skin. Some characteristics of the compound are that it is odorless and colorless, usually found in a crystalline powder form. It is not water soluble, but is fat soluble, which allows for it to accumulate inside of the tissues.

DDT or dichloro diphenyl trichloroethane was a insecticide used a lot during world war 2 for killing insects that carry disease. This chemical was dispersed into environments and it would stick onto the feet of certain insects and kill them as a result. It was developed in the 1940s to mainly prevent lice infections for soldiers because they had to wear the same pair of clothes when in battle. This lice problem pertained to children as well and these people were treated with DDT. However, as time passed DDT was used in more large amounts, and later they developed airplanes to dump tons of DDT among forests. This caused birds and other consumers to either die or become ill, and birds exposed to DDT often produced soft shelled eggs. Humans

It would appear that DDT would be the obvious choice to prevent cases of malaria in developing nations and all over the world. However, DDT is not without its potential hazards. DDT was used as a pesticide in the United States until it was banned in 1972. First employed as an insecticide in 1939, the white powder would kill massive amounts of mosquito larvae. Paul Müller actually won the Nobel Prize for first using the chemical on insects. The pesticide was used throughout the United States to combat more kinds of insect-pests such as gypsy moths. It was not

Reasons why DDT is a bad pesticide that is not only hurting falcons but humans too ever since DDT was starting to get used the Falcon population was declining in the article How DDT Harmed Hawks and Eagles paragraph 3 it states.“The dangerous consequences of spraying synthetic pesticides were not realized until 1962. An American biologist, Rachel Carson, published Silent Spring. The public learned DDT caused cancer in people. The synthetic pesticide harmed eagles and other birds of prey populations. Bald eagles were threatened with extinction in the lower 48 states.”

Name and explain three ecological factors that can be considered obstacles for Malaria eradication by Ferguson et al?

Malaria is a life-threatening disease. It is typically transmitted through the bite of an infected Anopheles mosquito. Infected mosquitoes carry the Plasmodium parasite. When this mosquito bites you, the parasite is released into your bloodstream.The parasites are spread to people through the bites of infected female Anopheles mosquitoes, called "malaria vectors.” There are 5 parasite species that cause malaria in humans, and 2 of these species P. falciparum and P. vivax pose the greatest threat.

Where malaria disease is found depends mainly on climatic factors such as temperature, humidity, and rainfall. The main areas where malaria disease is found are; Africa, Madagascar, India and South America. Malaria is transmitted in tropical and subtropical areas, where the host mosquito, of the genus Anopheles, is able to survive and multiply. There are approximately 430 Anopheles mosquito species, only 30 to 40 of which transmit the malaria parasite.

Where malaria is found depends mainly on climatic factors such as temperature, humidity, and rainfall. For example, at temperatures below 20°C, Plasmodium falciparum cannot complete its growth cycle in the Anopheles mosquito, and thus cannot be transmitted. Outbreaks often occur following periods of increased precipitation. This is primarily the result of positive effects on vector breeding, development rates, parasite sporogony and vector survival.

Other cultural factors interact with malaria susceptible countries to make the situation much worse. For example countries that have been impoverished by war, including civil war, suffer more than other countries. Angola is an example of this. Therefore countries in Africa have a denser malaria concentration if there is great poverty which is often combined with civil war. This is an example of a spatial pattern.
