These are engineering problems which, if implemented, could be a GREAT boon for conservative processes. Nuclear Energy, combined with renewable fuel sources (Ethanol, if we could bioengineer something with a much more favorable conversion ratio, it would be a great start), plus carbon sequestration. I am of the opinion that the only practical hope for us is Technology.
I am in accord with your opinion.
The only hope for us is to grow a backbone and stop being scared of our shadows. We are not causing this problem, if it is a problem.
