Jehanne -
Yes, I agree with you, except the problem isn't/won't be CO2.
Pollution in general, living an artificial life rather than the kind of life God wants us to live -- THAT is the real problem.
You know, nitrogen fertilizer causing algae blooms when it gets back to the ocean, GMO food, killing off honeybees, have you see the air in China where a bunch of our food is grown? Etc.
