americans living around the mississippi get up and evacuate every couple of years due to the flood waters, but they wait until it floods until they do it. the previous inhabitants of the region got out of the way every year, expecting the worse and no doubt preventing a lot of destruction in the process. that migration is ongoing. people just don't realize it.
less false dichotomies and more synthesis, please.
let me be a little presumptuous in suggesting that whatever is rebuilt in the region will be flooded again within a few years. you sure that's the best idea?
