Some scientists say a surgical removal of certain species would greatly benefit humanity. Certain species of mosquitoes co-evolved with humans—this means they've adapted to feeding on humans and depend on them for survival. Scientists say targeting these species would significantly reduce the number of deaths caused by mosquito-borne diseases while having minimal collateral damage on the environment.
You have to find out which species are carrying particular pathogens and then you can go after them. It's highly unlikely that you could eliminate them entirely, but there will be regions where the pathogens also occur, and that's where you want to take out the mosquitoes. We want to take out Aedes aegypti, if we can, in the Zika areas. And also yellow fever, which is persisting.
E.O. Wilson, a renowned entomologist and advocate for animals supports eradicating some species of mosquitoes on moral grounds. Doing so will saves lives.
I'm talking about a very small number of species that have co-evolved with us and are preying on humans, so it would certainly be acceptable to remove them. I believe it's just common sense. It's morality with a strong scientific basis that needs to be considered.
The problem with eradicating mosquitoes is like with all animals, they're part of a complex ecosystem. Getting rid of mosquitos might be fine, or it might throw the system off balance and cause an even worse situation. We wouldn't know until we do it. People have been trying to defy and control nature for centuries and more often than not, nature wins in the end. The benefits of eradicating mosquitoes is not worth it.
Many mosquitoes – harmless and otherwise – serve an important biological purpose. They can help pollinate plants as they feed on nectar (their usual food source, outside of that crucial blood meal period) and provide a vital source of food for larger animals. They're vital components of a complex ecosystem, just like every other living thing. Researchers in the Arctic worried that climate change would lead more animals to feast upon local mosquitoes, throwing the food web out of whack and leaving plants unpollinated. As it turns out, warmer water has actually produced an Arctic mosquito boom – but that's not great news for the baby caribou they feed upon.
