Google's Debug program plans to release millions of male mosquitoes carrying the bacterium Wolbachia in Florida and California to reduce populations of disease-carrying mosquitoes. According to CBS News, the released male mosquitoes do not bite and the Wolbachia bacterium causes eggs from matings with wild female mosquitoes to not hatch, reducing mosquito populations over time. The U.S. Environmental Protection Agency is reviewing the permit request for the program, which seeks approval to release up to 32 million mosquitoes. California health officials recently reported a mosquito sample that tested positive for a disease-causing agent. There is public unhappiness about Google’s plan to release mosquitoes. The ethics of releasing mosquitoes are being questioned.
