From the Ted Talk by Talya Hackett: Ethical dilemma Should we get rid of mosquitoes?
Unscramble the Blue Letters
Because of the pathogens they crary, mosquitoes are responsible for more human datehs every year than any other animal, including other humans. But very few of the 3,500 mosquito species actually transmit dealdy dsieeass to humans. So what if we could get rid of the most lethal mosquitoes? Over the last two decades, scientists have begun conducting experiments using engineered tlohnoceiegs claeld “gene drives” that could theoretically do just that. So, should we?
To begin grappling with this question, we have to get a sense of how the technology works. In the uasul process of inheritance, the genomes of each parent recombine randomly. So their opfirsnfg end up with the DNA that’s a rough 50/50 mix from their parents. But gene drives thwart this psroces and ensure they're passed on. Gene drives are found in nature but, using new gene-editing technology, scientists have also begun engineering them in contained labs.

Original Text
Because of the pathogens they carry, mosquitoes are responsible for more human deaths every year than any other animal, including other humans. But very few of the 3,500 mosquito species actually transmit deadly diseases to humans. So what if we could get rid of the most lethal mosquitoes? Over the last two decades, scientists have begun conducting experiments using engineered technologies called “gene drives” that could theoretically do just that. So, should we?
To begin grappling with this question, we have to get a sense of how the technology works. In the usual process of inheritance, the genomes of each parent recombine randomly. So their offspring end up with the DNA that’s a rough 50/50 mix from their parents. But gene drives thwart this process and ensure they're passed on. Gene drives are found in nature but, using new gene-editing technology, scientists have also begun engineering them in contained labs.
