Some ecologists who have again taken to claiming there is some special "balance of nature" and engage in butterfly effect speculation about ecosystems. They insist that Aedes aegypti mosquitoes are not ecologically useless, they are even necessary, but there is nothing positive they do that the 3,500 other known species of mosquitoes could not do, without killing millions of people per year. No new organism would magically appear in its niche and be even more effective at spreading diseases. Such claims that the cure would be worse than the disease were debunked as "metaphorical" concepts long ago. We don't allow "balance of nature" speculation to inform policy about other species - why worry about overfishing tuna if another species will magically appear and be even better than tuna? - so clinging to what scientists lament as an "enduring myth" is a disservice to those plagued with yellow fever, dengue, Zika, and more that we allow loud voices to insist that one mosquito being wiped out would set off an ecological catastrophe.
So let's accept that science is not what Thanos claimed in those Marvel movies or whatever other pop culture gibberish environmental groups promote. How to kill these ecologically useless disease vectors is what requires thought. DDT works, obviously. Though it was banned for use in the United States due to political reasons, and the EPA which banned it over the objections of the science community literally writes the book on how to spray it inside homes in other countries, it is never coming back here. Citizens in progressive states are overwhelminlyg on the anti- side when it comes to vaccines, GMOs, and natural gas, they grew up listening to Joni Mitchell songs, so unless it can be shown that DDT kills coronavirus they will oppose it.
