Yet in many cases, scientists acknowledge that the ecological scar left by a missing mosquito would heal quickly as the niche was filled by other organisms. Life would continue as before — or even better. When it comes to the major disease vectors, "it's difficult to see what the downside would be to removal, except for collateral damage", says insect ecologist Steven Juliano, of Illinois State University in Normal.
There's a certain strain of environmentalist that sees deindustrialization, technological regression, and human population decline as the solution to the world's problem. This perspective misses the mark, I think.
Human population decline would solve a lot of our environmental problems and is not necessarily tied to technological regression. In many developed countries it happens by itself and it could rather easily be helped along with some financial incentives, say, a tax on children.
The last thing we need is a tax on children in societies with sub-replacement fertility. A world without growth is a terrible place. (Before you object: yes, economic growth isn't the same as population growth. But to get economic growth with a declining population, you need productivity to grow faster than the population declines, and we're already having trouble keeping productivity growth up.)
