What are the advantages and disadvantages of using DDT for malaria?

since Rachel Carson's book, Silent Spring , has launched chemical DDT on infams, a strong pesticide was the subject of controversy. Responsible for the devastating environmental and health impacts that have received the chemical, its bad name, DDT as an insecticide also won the Nobel Prize and support many medical activists fighting malaria. The use of DDT for malaria has many advantages and disadvantages that cause environmental organizations, health organizations and governments to fall on both sides of the fence. The main questions to be asked in this subtle argument are whether long -term health and ecological impacts of DDT outweigh the health benefits of DDT for malaria and whether there are alternatives that could work better at lower costs. Malaria is a potentially deadly disease caused by a parasite that will be on certain types of mosquitoes. Because the parasite itself is so difficult to kill in large numbers, it was generally aimed at killing carriers. Since World War II people use DDT forMalaria and agriculture with great success. However, there are some major DDT problems.

DDT was banned, first in the United States and then worldwide, because of its harmful health and environmental impacts. As a persistent organic pollutant, DDT remains in the environment, especially in the soil, for a long time and does not dissolve in water. As they accumulate and the animals expose, the impact of health begins to appear in fish, other sea animals, birds and even mammals such as humans. Birds have shown that DDT causes eggs in eggs and is considered to be partly responsible for almost the extinction of the bald eagle. In humans, there is evidence that DDT causes deterioration of genetic integrity, cancer, breastfeeding difficulty, timely abortion and lower sperm quality, including negative health effects.

There are also convincing reasons why we should use DDT for malaria and the worldThe medical organization (WHO) supported the limited use of DDT for such health purposes. Malaria is most common in poorer countries, especially in Sub -Saharan Africa, so DDT is an attractive choice as a relatively cheap insecticide. The climate in these regions is also suitable for faster degradation of chemicals, which reduces its persistence. When so many people die of malaria, many DDT supporters cannot see any justification that or fighting disease with any available tools.

Many critics of DDT, such as Rachel Carson, promote cautious, limited use of DDT for malaria. Yet even the limited use of DDT in the field of affected malaria has led to serious health problems, negative environmental impacts and very danger of dDT mosquitoes. Some supporters claim that DDT restrictions should be abolished for more effective fight against malaria. Others say that this would only increase the above problems and would not ease the disease, especially in places where the climate allows mosquitoessurvive all year round. Alternative pesticides, physical barriers for mosquitoes and drugs to prevent and treat malaria are also available as substitutes or tools to be used in tandem with DDT for malaria.
