there is no expert or science that can fully understand the whole ecosystem and how it works, mosquitos and many insects are at the base of the food chain, the impact will probably be a domino effect that will make many other species extinct, where will this lead? nobody knows
Ok, this. This is the chain of reasoning I'm talking about.
It is the very height of hubris to say that the people who manage and study ecosystems don't understand them, and to imply that they are ignorant of something so basic as the food chain. I don't understand where this is coming from.
And there will probably be a domino effect that will wipe out many species? "Probably"? Like, more than 50% odds? Really?
When multiple professionals are willing to go on record saying the impact will likely be negligible, what makes you so darn sure they're wrong? The only place I can imagine this is coming from is some combination of "Science is Hard" and "Nature Messes You Up Whenever You Mess With It In The Movies"!
