China has got accustomed to having one child, and most couples don't want a second child.

This is tremendously good news for the future of China and the world: China with its current population is using its land unsustainably. Maybe with the coming decrease it could put an end to that.

If only we could convince other regions with still-exploding populations, such as India and much of Africa, to have small families, that would put off the consequent disasters.
