Removing top soil from school grounds to reduce radiation is a positive step. It does however provide a small harbinger of the enormous cost this disaster is going to impose in Japan for as much future as humans can reasonably foresee.
Generally nations recover from floods, chemical spills, rock slides, etc. and dare I say it, combinations of tsunami and earthquakes. Japan may recover economically but the damage to the land is permanent unless you look at history in terms of periods like the Jurassic.
It is questionable business ethics to promote PR that claims such disasters unlikely or impossible. It is questionable business ethics to subvert the government into downplaying or covering up incidents at your nuclear plants. It is questionable business ethics to pretend certainty when you don’t have any.
I expect giant corporations to lie, exaggerate and steal if at all possible. (Small corporations are much less likely to have these faults and are in many cases, excellent examples of morality and patriotism.) But permanently destroying the landscape has to considered unethical in an extreme sense.
