One of the big questions in the climate change debate: Are humans any smarter than frogs in a pot? If you put a frog in a pot and slowly turn up the heat it won't jump out. Instead it will enjoy the nice warm bath until it is cooked to death. We humans seem to be doing pretty much the same thing.
The world will change for the better when people decide they are sick and tired of being sick and tired of the way the world is and decide to change themselves.
