One child policy

Everyone knows of China's One-Child Policy, the BBC is running an article on it and how it has avoided overcrowding and resource issues families not having those 400M births that would have happened otherwise.

Our little pale blue dot is the only M-Class planet, we have precious little resources on the surface of the planet and China's One-Child Policy looks like a good decision to prevent overcrowding, and I expect other countries may fallow suit. After WW2 population was at 2.5B, now it is at 6.5B, and if no careful planning is done it will be 20B by 2050.

Nice quote from the BBC article:

"Compared with the world's other developing countries with large populations, we have realised this transformation half a century ahead of time."

One problem will be avoiding the one-child growing up spoilt, there must be many group activities, and sharing encouraged. Also the birth ratio of boys to girls is more different than in other countries.
