bruce...did you read:
"From: Bill D - PM

IF the situation is as Gore says, populations WILL try to move...and weak attempts will be made to try to control the process. And conservatives will stomp their feet and say "there goes the government again, trying to tell us what to do!"

If you think immigration is awkward now, just wait until all of Mexico & Central America and half the US decides to move north.

I don't see you advocating the reduction in population necessary to allow EITHER moving OR staying put and coping.
