You could be killing 100,000 people a day if things go differently than you expect.

Caution is in order.

I am not sure why this is downvoted, this is a legit point. If we eradicate mosquitos and they evolve to survive while creating another problem other than malaria, you literally can end up killing 100000 people every day instead of 1000.

Nobody has a way of eradicating mosquitoes. Particular species of mosquitoes are what is being targeted.

It is inconceivable to me how eradicating the malaria parasite by eradicating a few of the thousands of species of mosquitoes could end up killing hundreds of thousands of people every day. The much more likely scenario is that doing nothing allows the malaria parasite to evolve into something much more deadly (and that is pretty unlikely, given how long malaria has been around).

Clearly no one you know is in the malaria danger zone.

Care to spell out the "100,000 people a day dying" scenario?
