Dan, the answer to your original question is none of them.

"We continue to increase population without discussion"

Now that's not entirely true. Every now and again someone leaps up in NZ and says, "We must increase our population if we want our economy to grow." No-one points out that if you can get an economy to grow without increasing the population you've actually achieved something.

Someone, somewhere once said, "The best thing you can contribute to the next generation is not to contribute any children."
