Bad human communication leaves us less room to grow.

I don't think we're yet evolved to the point where we're clever enough to handle a complex a situation as climate change. The inertia of humans is so huge that you can't really do anything meaningful.

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.

Every daring attempt to make a great change in existing conditions every lofty vision of new possibilities for the human race has been labeled Utopian.
