It would be to allow DDT in malaria-ravaged countries.
How does the US stop Sri Lanka and other countries from spraying DDT?
Do these countries even have stockpiles of DDT, or even the means by which to disperse it on such a massive scale? Once again, only the US has the means to get such a meaningful thing done. Sadly, I believe that it will once again be thwarted due entirely to irrelevant political reasons rather than any sound scientific ones.
