I think I said it in another post, but my only inspiration for writing about this is that I have been following DSM for years (I first wrote about it here https://www.economist.com/technology-quarterly/2018/03/19/si...), reading papers and talking to people. Based on what I knew when I started reporting this several weeks ago, I thought it worthwhile to try and compare the impacts of land vs seabed mining. I found a rough comparison was possible, and that's the heart of the piece
Might respond more fully later, but am clocking off for now. The final thing I'd say for now is that all the hype and narrative I see runs in the other direction, against DSM. Those who are against it are chock full of nonsense claims like this will disrupt the global carbon cycle or destroy fisheries, when basic science shows that it won't (or, if you don't like the casual use of certainty, that it is very very unlikley)
