Hmm... plastic or airplane pollution is just enough to create pollution problems, but I think they it's way too small to be a suitable vector for this kind of large scale delivery.
Micro-plastics are plentiful in the oceans in particular because they degrade very slowly, whereas we want algal bloom to quickly devour the iron, so that would not match.
I appreciate the funny idea though! ^^ To turn these calamities into features!
- cynusx 6y agoI am not so sure about that, I think highly concentrated iron is less productive for carbon sequestration than less concentrated iron. In addition because the flow of plastic is constant it may lead to semi-permanent algae rather than a boom and bust of an algae bloom. The slow degradation of plastics is actually a feature in that sense, as a single piece of plastic will fertilize a larger area of the ocean. It may also lead to algae growing on the plastic and then dying, leading it to sink and no longer represent a threat to wildlife.
