It’s not visible but the toll of radiation on other living beings and the environment is, and should not be neglected imo.

When I am saying that the death toll from Fukushima is between 0 and 1 it is because the effect of radiation is accounted for and that the level of exposure we are talking about makes it possible that it raises additional deaths by 1. When a zone is declared radioactive, humans tend to avoid it, which does wonders for all other lifeforms.

because the ocean is not a dumpster.

Oh I think I used a mistranslation, I did not mean to say “water bed” but "water table. I am not talking about using the ocean as a dumpster. It would be a very poor idea. We are talking about geological storage, which means within the rockbed, in geologically stable regions. All the projects I am aware off are land based. And when they are below the water table, there is very little ways for it to raise to the surface.
