Also proposals to breed and seed the stuff the way we do shellfish already.
Issue is that algae and what have is not always good. Especially when its referred to as a bloom.
You need an aggressive approach to wetlands restoration and ocean health. Which would lead to restoration of higher, healthy algae and phytoplankton levels. And bring the ocean back up on that whole “giant active carbon sink” thing.
Too large a bloom in a localized area effectively leads to a dead spot there. We like these big, grand, fix it fast gestures. But to me, its always sounded more likely to seriously fuck the ocean fast. Rather than rapidly reverse global warming. I mean I get to see (and smell) the effects of nasty algae blooms first hand every summer these days. I don’t see that as “solving” anything.
