I agree with Caribou! He see's the real world. And even in Alaska, what he sees way too much of is people! The world is greatly over populated, and a plateau hasn't been reached--in the US, population has slowed, but worldwide, man just keeps spitting 'em out! Aids was a hope, but didn't seem to pan out. Man is rapidly destroying the planet over food (and the associated need for water), not through "global warming". It is obvious that no politician even wants to mention the real problem--over population! This country has gotten so crowded it is sickening--and I live in Nevada! China, for all it's wrongs, has done one good thing--1 child per couple! We need that in the US. And the world. Not forever, obviously, but for several generations.
