“Bad mosquitoes spread disease. Good mosquitoes can stop them,” the Debug Project team says on its website. “Debug is a group of scientists and engineers developing technology to raise and release sterile mosquitoes to eliminate the ones that carry disease. Mosquitoes kill more people than every other animal combined. One species, Aedes aegypti, carries diseases such as dengue, Zika, yellow fever, and chikungunya which make hundreds of millions of people sick every year.”
