All I want is the facts, ma’am.
Natalia, my stance on DDT began when I looked at the situation and made it the subject of a 15 minute radio broadcast in which I suggested that DDT appears to be the most effective, the safest, and the cheapest pesticide ever invented. I was surprised at the reaction that transcended the bounds of common sense (it seemed to me). Demands that I be thrown off the air, insinuations that I was trying to poison humanity – one lady wrote in that I put the environmental movement back 15 years. (I suppose it didn’t help that I pointed out in another program that 15 years in 15 minutes seemed to be a pretty effective program.) So, I really looked deeply into the whole mess. There seemed to be not a single scientific reason for banning DDT, but a lot of good reasons for continuing its use. However, the propaganda against it was lurid and frightening. Rachel Carson’s musing “a world without a robin” was quiet compare with the shrieks from those who thought DDT was the work f the devil. Not that there was much desire to keep making it. At the time it was banned, only one manufacturer – the Montrose Chemical Company in Torrance California was making it. The big chemical companies didn’t want to make it because there wasn’t much profit in it. The company was messy pouring lots of waste DDT into the sewers that emptied into Santa Monica Bay. I postulated at the time that if the pelicans on Anacapa Island were laying thin-shelled eggs, it could be because of this DDT waste. I was closer than I realized. A study released within the last year or two found an estimated 110 tons of DDT on the bottom of Santa Monica Bay. The waste showed a footprint that leaned to the north – towards Anacapa. Maybe? I don’t know whether DDT is the best solution to the malaria problem – but it does work. And as I found it doesn’t kill off the birds and animals in the process – and there appears to be no record of a single human death solely from DDT in the 25 plus years in which it was used. I suggest that we go with what works. There may be treatments of the problem that are far better, but we cannot experiment with these methods for ten years while people are dying. Maybe WHO should resume the spraying of huts – last time they used 335,000 sprayers treating the huts twice a year. That seemed to work. It would also give a breathing space to the people seeking better methods. Of course, DDT may no longer work. In any event, scientists should be coming up with a similarly benign replacement for use when mosquito resistance builds. The trouble is that they have been turned off by the intense furor from the environmentalists – which is a pity. Particularly as the USP found it might be a cancer inhibitor!

It's difficult to tell. Did you actually read the entire report, or even just the case studies? Saving lives is the objective, and saving more lives is the outcome of an integrated bio-management approach.
