Florida releasing millions of genetically modified mosquitoes

The video discusses a plan to release 750 million genetically modified mosquitoes in the Florida Keys to reduce disease-carrying mosquito populations. The Florida Keys Mosquito Control District spends over $1 million annually to combat the Aedes aegypti mosquito, which spreads diseases like dengue and Zika. Oxitec, a biotech company, has engineered male mosquitoes to carry a lethal gene that prevents female offspring from surviving to adulthood. However, environmental groups warn of unforeseen outcomes, citing a previous Oxitec program in Brazil where some female offspring survived, potentially making the local population more resilient.
