You're ignorant. Even India is barely growing these days, I think the only countries with really unsustainable birthrates are in Africa (and the death rates are so high there that the birthrates are sort of sustainable anyway).
There is no country in the world with an overpopulation problem. The problem lies more in resource and food distribution, rather than amounts. In fact the amount of food per person on the planet have been generally increasing in the last 30 years.
