All of the homes in an entire tropical country can be treated with the amount of DDT that once might have been used on a single farm. Studies have also shown that, properly used, DDT does not pose serious health risks to humans. It breaks down under natural environmental conditions much more quickly than was once thought. Indeed, the proposed DDT ban would be a disastrous example of eco-imperialism at its lethal worst. Dr. Charles Wurster, former chief scientist for the Environmental Defense Fund, was once asked if he thought a ban on DDT might result in the use of more dangerous chemicals and more malaria cases in Sri Lanka.

We have too many of them. We need to get rid of some of them, and this is as good a way as any. His views are hardly atypical. It is our duty to cause them. It is our species' duty, relative to the whole, to eliminate 90 percent of our numbers.
