What does this button do again?
Well in this case, maybe it's used because the pros outweigh the cons. Maybe the mindset is that saving thousands of human lives is more important than the detriment to wildlife and the environment that DDT can cause? Or are less things affected there/ has DDT been modified at all? I'm a little unfamiliar with the spraying in Africa.
There is no environmental impact when it's used indoors. Its when DDT was being used outside that it caused all of the issues with bird eggs.
