What could go wrong?
Can't tell if you're asking rhetorically or not, but I genuinely don't know. I tried to read a bit more, and it looks like most of the gripes are trivial and boil down to "don't play god." I don't know where mosquitoes fit in the food chain, but they are probably among the world's leading killers. Malaria kills 3000 children per day {pdf warning}, so whatever fears people have of GMOs better compare favorably with that.What could go wrong?
Oh man. I want this to work so bad. But if there is any year in which it is a TERRIBLE idea to try messing with Mother Nature and her unfathomable and awesome adaptability... it's 2020. Can we let all the scientists go on holiday for the next three months, and just get through the end of the year without bringing on (another) apocalypse? Please? /s
