Idiotic biotechnology

So this is a thing in America:

A release of mosquitoes genetically engineered to produce dead offspring and thus combat the spread of the Zika virus has been approved in Florida by the US Food and Drug Administration

in an experimental trial on Key Haven, a small island in the Florida Keys

It is not clear how many engineered mosquitoes could be released. Parry said it could vary from 20 to 100 mosquitoes per person on the island.

Doesn't anyone realize the abject fucking stupidity of releasing genetically modified mosquitoes that produce infertile offspring? What's the point of genetically modifying a species if the modified individuals can't reproduce? Do they fucking know that there are billions of people living in tropical regions of the world, so to release 20 mosquitoes per person they would have to make tens of billions of male mosquitoes who cannot even fucking breed? Fucking inbred idiots. And someone's paying them...

Interesting. I remember talk of this when West Nile Virus was around several years ago.

I don't think you understand what is going on. The genetically modified species is released into the wild where it attempts to mate with the natural species. When it does, the offspring is dead, and it has effectively blocked that natural individual from reproducing, thus a much lower population for the next generation, which is even more likely to mate with the engineered species.

Do they fucking know that there are billions of people living in tropical regions of the world, so to release 20 mosquitoes per person they would have to make tens of billions of male mosquitoes who cannot even fucking breed?

Yes, and? Just make the DNA require that the eggs be hatched in the presence of a certain chemical that never occurs in nature. Great, now the new mosquitoes can be breed in special breeding grounds but not in the wild. What's the big deal?
