BBC World Service - The Inquiry, Why Don’t We Eradicate Mosquitoes?

Mosquitoes cause a huge number of deaths. But getting rid of them would be complicated.

Mosquitoes cause a huge number of deaths. And some argue they have little ecological importance. But getting rid of them would be complicated.

Mosquitoes are the most dangerous animals on the planet. They spread diseases - malaria, dengue and zika – that kill huge numbers of people and cause suffering to many more.

So why not eradicate them?

It wouldn’t be easy. Scientists in Mali have found the mosquito is a surprisingly formidable foe, able to hide for months and evade capture. Other scientists are working on genetically-modifying mosquito populations so that they can’t breed.

But could releasing these re-modelled mosquitoes have unintended consequences? And might we accidentally destroy ecosystems by removing mosquitoes altogether? It turns out this tiny creature presents us with huge practical and ethical problems.
