War contributes greatly to global warming which shouldn't surprise us. All those bombs going off all those rockets all those planes and helicopters. All that fuel of various kinds being used. It pollutes the air and water of this very fragile and interconnected planet.
Just as there's garbage that pollutes the Potomac river there is garbage polluting our culture. We need an Environmental Protection Agency to clean it up.
Not everyone can be trusted. I think we all have to be very selective about the people we trust.
