Dichlorodiphenyltrichloroethane (DDT) was an effective and inexpensive pesticide used to kill malaria-spreading mosquitoes. The environmental effects of DDT have been highly debated between scientists. While some scientists believe studies support a negative impact of DDT on the ability of birds to produce viable offspring, other scientists claim that there are major gaps in the research data that leave uncertainty in the findings. With this debate underway, do you believe the U.S. Food & Drug Administration (FDA) has taken a proper position in banning the use of DDT in the United States? With the emergence of other mosquito-carrying diseases, such as the Zika virus, do you think the FDA should revisit its position on the use of DDT?
