Or a gene drive that renders male offspring sterile.

You say "stupid", I say "recurring revenue".

Do you actually have arguments to object this from a moral standpoint or it's just a snarky comment? Because I would really love to hear some moral objections to the matter.

While I'm all for wiping out the race of mosquitoes, I think it's arrogant on our behalf to assume that we can just remove a species completely from an ecosystem without consequences. If we're really lucky, the consequences will be minimal: spiders and other predators will simply find something else to eat. But if mosquitoes had some heretofore undiscovered critical purpose for the environment, we might have seriousl…

There's nothing stopping us from preserving enough specimens in labs around the world so that we can repopulate.

This problem has been studied: https://www.nature.com/news/2010/100721/pdf/466432a.pdf

But what if mosquitoes are actually bad for the environment? By not removing them we can be screwing things up!

The 'environment' is often in balance. Any abrupt change can cause oscillations and crashes. May as well ask "By not removing this brick from the wall, I may be screwing the wall up!"

Or perhaps it's prudent and by design. Mosquitos are part of a complex ecosystem that we barely understand. Irreversibly wiping out a _species_ without fully understanding the consequences is a drastic measure.

Maybe it's true, but usually it's human hybris. I doubt that we understand our ecosystem enough to make these kinds of judgements.

You could make the same hand-wavy "what-if" arguments about removing smallpox from the ecosystem.

Or polio.

Or malaria.

Because they used to not exist in these areas. That's what the word "invasive species" means.
