Cyanobacteria cultivation is an old idea[1] and is limited by more than just phage. I did the math on carbon removal in a controlled environment somewhere like Nevada, and it could contribute to climate solutions. If Church is suggesting we release GMO cyanobacteria into the ocean, that is a whole separate category of idea, somewhere between Guam's Brown Tree Snakes and Ice Nine. If it succeeds, we will introduce a new kind of ocean trash - an organism with no predators. But phage is likely just mutate anyway. IDK how close you've been to Church or his orbit, but most of his ideas are mostly clickbait.

In the case this one isn't, the release of genetic modifications into the wild will be a debt our children have to pay, the way we are paying for our ancestors use of CO2.
