I'm not equating killing yourself with not having children. Of course they are not the same. I'm simply reflecting irq11's logic back at him: if the only measure by which you judge a solution is how much CO2 emissions are reduced then killing yourself is the best solution.

irq11 does not consider the costs of implementing a world-wide child reduction policy. A combination of solutions including education, birth control, electric cars, reducing flying, solar energy etc. is FAR more realistic than the "no kids, no cars" approach. He complains about harsh reactions but he is the one who started this off from a very antagonistic perspective that everybody is just a mindless consumer while he is the arbiter of harsh truths that people are too weak-minded to admit to.
