DDT is a dangerous pesticide that kills and repels mosquitos more effectively than any other known substance. This chemical was used widely in the developing world to prevent malaria, a disease that not only kills the populations of these areas, but the economies, but has been stopped due to pressures from the developed world. The developed world wants use of DDT to stop because it is a chemical that takes years to decompose, and it bioaccumulates in humans, which could be dangerous.
The continued use of DDT would hurt the environment as it is a pesticide that would accumulate in animals, leading to deaths. Also, the discontinued use of DDT would increase the mosquito population, increasing the cases worldwide of malaria.
Should use be stopped now or should developing countries use DDT?

Post due 12/4
In India alone, 140 million people drink water that is contaminated with pollutants, despite measures to improve water quality. Sarvajal is a company that is trying to tackle this problem with water ATMs, created with sensory equipment and cloud technology. This invention not only provides clean water to many rural areas, but allows for the women and children who used to spend their time only retrieving water may now divert their attentions.
The still growing population of India will begin to stress the water supply beyond capacity, creating a detriment to the region as the water table will fall. The fall of the water table will not only hurt the human populations of the area, but all natural habitats as well.
Will the improvement of water in India be enough to halt over use of the area's resources?
