That upsets me for various reasons.

And while I understand that keeping mosquito populations in check helps combats many diseases I also KNOW mosquito, as maligned as they are, have a function in an ecosystem. Their juvenile form feeds some fish and amphibian populations, their adult form feeds some spider, insect, bat, and even bird populations. Both forms play host to microscopic life. And as an arm chair enthusiast of Things Biological I strongly suspect their bite not only transmits harmful bacteria and viruses but also beneficial bacteria and viruses. At this point there is this deeply ingrained belief that we will fix the consequences of our tinkering with more tinkering. Ie. "That's a future fight." We're such an optimistic species.
