I have to agree with you here. How many people have been killed in hurricanes, fires and other natural disasters because the were too stubborn (or too stupid) to evacuate when told that they should? And how many more have been killed because they were never informed of a disaster on the horizon?
But asking people to accept individual responsibility? What a bizarre concept! So politically incorrect of you! It's much easier to blame your problems on the government, or on the industrialized nations, or on any other scapegoat you can find.
Government's job is to maintain the status quo, keep the peace. Moving large segments of population around goes against the grain. How can you control a population on the move? Don't rely on them to help you!
In my opinion, if you think you can do something to reduce the effects of global warming, and if you have the desire and the resources to do it, then by all means, go ahead. But do it because you think it's right and necessary, not because some politician or whack-job ecoterrorist tells you to do it. Meanwhile, I'll keep building my fortress of solitude, somewhere in the mountains.
