Humans murder around 475,000 other people each year. Snakes kill around 50,000, while dogs (mainly from rabies transmission) claim another 25,000 lives.
Zika virusâs spread adds urgency to gene editing that could allow scientists to program the insects to die off, but the idea is fraught with quandaries. Updated Sept. 2, 2016 1:37 p.m. The death toll from diseases carried by mosquitoes is so huge that scientists are working on a radical idea. Why not eradicate them? Mosquitoes kill more humans than any other animal and were linked to roughly 500,000 deaths in 2015, mostly from malaria. For more than a century, humans have used bed nets, screens and insecticides as weapons, but mosquitoes keep coming back. They are now carrying viruses like Zika and dengue to new...
