So, new paper out, pointing to the manner in which whale poo both fertilises the ocean and also, as some of it simply sinks to the bottom and eventually becomes rock, sequesters carbon. Also, som,e of the plankton that feed on the poo similarly sink and become rock.
Thus we should have more whales and I thoroughly agree (one of the few environmental campaigns I am fully behind is the ban on whaling. Not just because they are majestic but because this is a classic commons problem that can only be solved through either private property or regulation and regulation is the correct choice here).
But do note: all of the same arguments apply to iron fertilisation of the oceans. Which is why I support that too although for some strange reason the environmentalists don’t agree.
