In its early days, DDT was a popular pesticide because it was toxic to a wide range of insect pests, yet it appeared to have low toxicity to mammals. DDT was also persistent, which meant the pesticide didn’t break down rapidly in the environment and therefore did not need to be reapplied often and since DDT was insoluble it did not wash off by rain or other weather conditions.

This discovery created wide public interest and made people aware that chemicals were polluting the environment. As a result DDT was banned for use in North America and other countries in the early 1970's. Though pesticides, such as DDT, may decrease the number of insects, throughout history it has been proven that there is a detrimental effect upon the environment, animals and humans as a result.
DDT is acolourless chemical pesticide, also known as dichlorodiphenyltrichloroethane, whose purpose isto eradicate disease-carrying
and crop-eating insects. It wasfirst isolated in Germany in 1874, but not until 1939 did the Swiss Nobel Prize-winning chemist Paul Müeller recognize it as a potent
nerve poison on insects. Thus, DDT wasfirst used heavily in World War II for preinvasion spraying, DDT was disseminated in great quantities thereafter throughout the world to combat yellow fever, typhus, elephantiasis, and other insect-vectored diseases. In India, DDT reduced malaria from 75 million cases to fewe…
