Yellowstone is precious because land without people on it is precious. The sea covers 71 percent of the earths surface and has no humans on it anywhere.

The areas with nodules containing the the right stuff is very small from my memory - haven't got a reference.

So is the damage going to spread wider than that area? I can see why people want to study it. I just don't reject the idea as I think the climate situation is a lot more critical than people like to imagine and we should have options.
