As for the concerned Conchs, they have little or no power to stop the plan if it's approved. Even if they fill a petition with signatures and persuade the City Council to pass a law against mutant mosquitoes, the public health authority granted to the Keys Mosquito Control District trumps the power of the city. Biddle, the former dengue patient, doesn't necessarily want to stop the plan from going forward; he just wants independent, peer-reviewed assurance that Oxitec mosquitoes are safe.
"[Oxitec] should have to do a five- or six-year study in the Cayman Islands and see what really happens," Biddle says. "What are the effects on people? What are the effects on tourism? What are the effects on the disease? And what are the effects on the ecosystem? That's what we should be studying. And still, without these findings, we're going to put something in the Florida Keys that's genetically modified, and we don't know what's going to happen."

Doyle is afraid that it will take another outbreak of dengue fever for people to see the wisdom in his plan. "I'm optimistic that it will happen someday," he says. "But I think nothing will happen until there's some external push to make something happen, like if we see dengue again."
While he and Oxitec wait for a federal yea or nay, Doyle does his best to assuage the concerns of people like Biddle and local lawmakers who remain opposed to the idea. A recent survey among Keys' residents found that 30 percent supported it, 30 percent were against it, 8 percent were unaware, and the remainder were undecided. If those numbers shift and the majority turns against the project, Doyle hints that he will still push ahead.
"My job is to protect them," he says, "even if sometimes they don't want to be protected."
