You had me at the opening paragraph, both very amusing and absolutely on point. There's no way humanity is getting out of this one. The world's population keeps rising, the poisoning or land, sky and sea continues to accelerate. Convenience is the ultimate trap.
Reminds me of the wonderful and dare I say prophetic line in the original 12 Monkeys movie:
"I think, Dr. Railly, you have given your "alarmists" a bad name. Surely there is very real and very convincing data that the planet cannot survive the excesses of the human race: proliferation of atomic devices, uncontrolled breeding habits, the rape of the environment, the pollution of land, sea, and air. In this context, isn't it obvious that "Chicken Little" represents the sane vision and that Homo Sapiens' motto, "Let's go shopping!" is the cry of the true lunatic?"
I too have no children and I think that's my best contribution to the future :-)
