Suppose that we have the ability to make mosquitoes extinct, what would the side-effect of such extinction be other than the fact that there won't be any mosquitoes left? Is it worth it to make mosquitoes extinct if there is a side-effect?
There was actually just such an article in Nature recently.
"They don't occupy an unassailable niche in the environment," says entomologist Joe Conlon, of the American Mosquito Control Association in Jacksonville, Florida. "If we eradicated them tomorrow, the ecosystems where they are active will hiccup and then get on with life. Something better or worse would take over."
