Child births are down in rich countries. However, to compensate those rich countries import people and those people end up living like Americans or Europeans. There is also the fact that wealth increasing worldwide and consumption correspondingly is increasing. My statement about having fewer kids was meant to apply to the whole world.

Great, we have enough food. There is more to life than just food. In addition to having enough food we have plenty of pollution too. We are toxifying our environment. This is not abating.
