No worries, if we don't do it the planet will balance things out for us in its own bloody and heartless way through famine, war and pestilence.
Honestly, Art, when I think about how politicians go about "averting disaster", I think I'll take my chances with the wrath of mother nature. At least she only deals in reality.
The alternative to "famine, war and pestilence" is us voting for government-run famine, war and pestilence. Let evolution take its course, I'm feeling fit today.
