It can also cause premature births. DDT has a dangerous effect on humans.
.
Another reason that we should not use DDT is the effect that is has on Animals. DDT has a large effect on birds. Bioconcentration is very high in birds. After birds like brown pelicans and bald eagles lay eggs they usually end up finding omelette like substances in their nests instead of eggs because their shells are not strong enough to support the weight of the tiny bird inside. Also, DDT has been demasculinizing alligators. It has been known to turn male into female fish that can bear viable young. .
The last reason that DDT should not be used on the environment is because it takes it a long time for then to degrade and can spread even to where it isn't used. Even though DDT was banned in the United States of America in 1972 they can still find traces of DDT and DDE in the soil today. DDT can be sprayed here in Canada and found in the fat of a polar bear in the arctic due to bioaccumulation. DDT takes a long time to exit the environment and can spread to anywhere.

DDT should not be banned in countries where they use it to prevent malaria and other diseases. DDT is an excellent mosquito repellent, and quite inexpensive, therefore it is favoured in countries where they do not have a lot of money to spend. Many countries have witnessed the amazing ability that DDT have on reducing malaria. Greece saw malaria cases drop from about 1 to 2 million cases a year to close to zero thanks to DDT. In India, malaria deaths went from 2,800,000 in 1948 down to 17 in 1964. Then in 1969 when DDT was taken away the cases rose back up to 2,500,000. When Sri Lanka stopped using DDT, the number of malaria cases rose again to 2,500,000. Other diseases that DDT prevent is break-bone fever, lyme disease, and leishmaniasis where the virus erodes away at the face leaving the person horribly disfigured. Cases have been reported in hunting dogs in the United States and Ontario, Canada.
