Yeah. Although I didn't explicitly state it, this is what I was implying. For example, could plastic-eating-bacteria "super bloom" in a plastic rich localized area of the ocean - suck up all the oxygen with it's bloom and kill off competing species of fish, plankton, etc... causing food chain disruptions? Could a localized super bloom acidify a localized coral reef with the C02 byproduct?

I'm no ecologist or scientist, so I am not saying that it necessarily would happen, but we should think through these things as a matter of due-diligence before proposing that we toss this stuff in the ocean at scale.

What makes you think that the researchers would not also be investigating for unexpected and potentially dangerous side effects before "toss[ing] this stuff in the ocean at scale"?
