Well here in the southwest we've been under a long term drought with occassional breaks, a steady influx of people into the area that doesn't look like it will end soon. At some point the resources here will reach their limit. All it will take a serious climatic episode to break the system. What happens to apparently civilized people when those kind of events happen? Civil unrest, violence, or worse. What if it were a global climatic change? I don't want any part of it.
