> How about we release this waste water in Japan's rivers, upstream of their purification plants, if it's so safe. Surely it will be thoroughly diluted by the time it ends in the tap water, below the radioactivity of a banana. I understand and am sympathetic to the skin-in-the-game argument here. But it seems to me there are a couple problems: First, releasing waste water into an ocean would dilute it much more than in a river or stream. A back of the envelope calculation would show that the concentration at a waste water plant on some river would be much higher than the concentration in the ocean. Second, it's not clear that the people making the decision (like the Monsanto guy) wouldn't refuse to drink as well, whereas less wealthy Japanese would be subjected most likely to toxic water. I get the argument, and maybe there is some way to enforce some skin in the game, but this is not it.
