I am not sure where you got the impression that what I am advocating is about mosquitoes. I have ONLY made general statements about the craziness of messing with the ecosystem without understanding it. *You* are the one taking the very easiest example on your side. You are willing to risk the continued existence of humanity without even checking first. I am not. As to extinctions WWF says: " The rapid loss of species we are seeing today is estimated by experts to be between 1,000 and 10,000 times higher than the natural extinction rate.* These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. If the low estimate of the number of species out there is true - i.e. that there are around 2 million different species on our planet** - then that means between 200 and 2,000 extinctions occur every year. But if the upper estimate of species numbers is true - that there are 100 million different species co-existing with us on our planet - then between 10,000 and 100,000 species are becoming extinct each year."
