Ausador, I live in a medieval city. I can see where the seashore used to be in medieval times. It is very far from where it is now. Its not that difficult to imagine having to abandon some buildings and perhaps building some seawalls over the course of 100 or even 50 years. Would avoiding that justify for example one child policy? I don’t think so.

If the same were to happen in the course of a few years its already a different matter.

Charles, all I see is some discussion on cap and trade and then a whole lot of babble about changing attitudes etc etc.. Since so many call cap and trade BS, it is not altogether clear what for example you want done.
