Learn about the pros and cons of eradicating mosquitoes, in this episode of Gross Science from NOVA. Mosquitoes can transmit many diseases, including the Zika virus, which is correlated with birth defects in babies. Genetic technology, such as the CRISPR gene drive, has the potential to keep mosquitoes from spreading disease. With the CRISPR gene drive, scientists can easily insert genes into organisms that could keep mosquitoes from transmitting a certain disease or that could ensure that all baby mosquitoes are born male, which in time would effectively wipe out the population. This powerful tool has the ability to rapidly change whole populations of fast-breeding creatures in the wild, but it brings up many ethical questions. This resource is part of the NOVA: Gross Science Collection.
