"I care not what role mosquitoes serve. We will help the planet adapt to their absence. Like IP lawyers, they should be made extinct."
Very well, please explain to several species why they are ordained by our idiocy to extinction. Then, explain to those who predate upon them for survival.
You can also explain how new products will be brought to market without profit, as copyright and patents would go extinct, in a scarcity economy.
The very first part of examining a problem is examining what the problem is and next, what mitigation will do in terms of good and harm. If the mitigation creates significant "ripples", it is intensely scrutinized and either abandoned as unpredictable or guarded considered further.
A prime example is to consider Microsoft Windows as a mosquito (or Martin bird, if you prefer), exterminate it and the overwhelming majority of malware in the world would disappear.
Regrettably, the overwhelming number of computers in the world would also cease to operate. Costs would abound in training staff on using permitted operating systems, support costs would crush entire economies.
Yes, that is the reality of it, like it or not.
Personally, I'm OS agnostic, using a half dozen quite happily for various purposes.
But, in a complex environment like a planet, making a significant change could eliminate dozens of species that may very well include the species causing the significant change.
Much like making a significant change in DNA coding for a protein. The result may work out brilliantly, but most of the time, indeed, the overwhelming number of times, it is not rewarded with survival.
