>My answer to his challenge is: Yes, larger populations mean we have more of our greatest resource -- ourselves. Our creativity and ingenuity has developed solutions to our greatest problems, but we need true and accurate information so that we make better decisions and work toward a solution.

Exactly. Scientific and technological advancements help everyone (at least potentially) because you don't have to divvy up knowledge. Even better the rate of scientific advancement tends to increase with a larger existing knowledge base. Ultimately more population means (much) more advancement. That's the most exciting aspect of China and India's advancements in recent decades. To play amateur psychologist, I suspect that why this isn't immediately obvious to people like Dr. Bartlett is because they don't think in terms of scientific progress.
