Humans ... not so smart creatures that create things and do things that work against their own best interests.

The rich "swap money" among themselves on the stock market and the poor, when they do vote, elect leaders at the local and national levels that don't really care about their welfare.

None of it sustainable. Mother Nature will have the final say so ... even if we don't like it.

Fortunately I am old and won't have any grandchildren. My son has a skill set that will keep him going for a while.
