but if you read the article, it gave me the impression that millions upon millions would be dying in short order here...
how much of that birth rate comes from those areas that are affected by THIS?
Where's "here"? The article was published in an Australian newspaper. And it mentions nothing about a risk from malaria in the United States, Australia, or indeed in the industrial world... it specifically says that most of the deaths are in Africa. (I'll wager that the majority of the remainder are in southeastern Asia.) Millions of people are dying; over a million a year, over 50 million since DDT was banned.
how much of that birth rate comes from those areas that are affected by THIS?
A very large part of it, considering that the birth rate is highest in the developing nations, which are also the poorest and hence least able to afford alternatives to DDT, and home to many infectious diseases that have been largely conquered in the industrial world.
