I would like to pick your brain a little bit more in regards to DDT use. Some proponents are suggesting to open the floodgates again for using DDT in to control the Zika virus. As you may know, there is currently no medicine or cure for Zika, and so far, only DDT is the most potent solution as seen with its results in controlling malaria. How do you stand in regards to lifting the ban on DDT for this particular purpose, at the expense of the environment?
