Insanity - You said "I am not denying that we should not strive to conserve resources; however limiting number of children to conserve resource is not logical because human beings not just consume - they also add value in some form or other. So the pie is not fixed it keeps increasing"

What value do human beings add to consumption of natural resources?

Limiting the population is not a matter of choice anymore. It's a matter of global interest. We have to learn from the Chinese experience. Their one child policy is a success story worth emulating. We can no longer afford to be selfish and hide behind books to do what we like. We have to think of the issues of extinction of our race altogether. We still have time and I believe we can win this race and save our planet. If you get a chance go to Youtube and watch an award winning documentary called "Home". It might not be to your liking but it definately proves a point that iám trying to make here. we the humans have become our own biggest enemy after we have successfully pushed every other resource on this planet to extinction.
