We finally may be able to rid the world of mosquitoes. But should we?

They buzz, they bite, and they cause some of the deadliest diseases known to humanity. Mosquitoes are perhaps the planet’s most universally reviled animals. If we could zap them off the face of the Earth, should we? The question is no longer hypothetical. In recent years, scientists have devised powerful genetic tools that may be able to eradicate mosquitoes and other pests once and for all.

Now, some doctors and scientists say it is time to take the extraordinary step of unleashing gene editing to suppress mosquitoes and avoid human suffering from malaria, dengue, West Nile virus and other serious diseases. “There are so many lives at stake with malaria that we want to make sure that this technology could be used in the near future,” said Alekos Simoni, a molecular biologist with Target Malaria, a project aiming to target vector mosquitoes in sub-Saharan Africa. Yet the development of this technology also raises a profound ethical question: When, if ever, is it okay to intentionally drive a species out of existence?
