Is man responsible for the Mississippi flooding this year?

It may be like that age-old question, "If a tree falls in the woods where no one is there to hear, does it make a sound?" Similarly, if people weren't living beside the Mississippi, would we still call it a flood? People always seem to manage to make natural disasters worse than they should be by careless building in dangerous places and making cockamamie decisions. The Endangered Species Act signed by Nixon has been abused since it was enacted. It seems these well meaning Republicans are always seem to be signing these feel good legislation and agencies that end up having catastrophic unforeseen and unintended consequences. If Man were declared an endangered species, maybe we could have some protection from these feel good laws. Perhaps we could use AGW and declare man as the most endangered species and therefore deserving of extra protrection.
