Given the understandable concern that we are in the millennia-long process of effecting a cataclysm on our planet, it may come as a surprise that researchers are now developing a technology that could allow for the deliberate eradication of any given species.
Mosquitoes are deadly disease vectors. Dengue fever, West Nile virus, and malaria are just a few of the calamities they help spread. Hundreds of millions of people suffer every year from mosquito-borne illnesses. Often, our best defense is to stop or kill the insects—we erect nets to keep them at bay, fight them with pesticides, and have even used the “
