Malaria as "population control"?

The latest column by Walter Williams, Deadly Environmentalists, includes a couple of quotes that I'm sure have been widely commented on around the blogosphere. But they are so striking, I thought I'd quote them in case readers haven't heard them. After noting some of the proven benefits of DDT, Williams writes:

Environmental extremists see DDT in a different light. Alexander King, co-founder of the Club of Rome, said, "In Guyana, within almost two years, it had almost eliminated malaria, but at the same time, the birth rate had doubled. So my chief quarrel with DDT in hindsight is that it greatly added to the population problem." Jeff Hoffman, environmental attorney, wrote on grist.org, "Malaria was actually a natural population control, and DDT has caused a massive population explosion in some places where it has eradicated malaria. More fundamentally, why should humans get priority over other forms of life? . . . I don't see any respect for mosquitos in these posts." Berlau's book cites many other examples of contempt for human life by environmentalists and how they've made politicians their useful idiots.

Ouch. Malaria as human population control? Respect for mosquitos? DDT use is bad because it added to the population problem? I don't have the context for these quotes, but based on Williams' use of them, I don't think these guys were joking when they made these statements.
