No way should we even allow this to happen. Countries shouldn't continue to boom in population when their societies can't even function.
So support local school systems with all might, which also means countering prejudice and religious bigotry of some locals. Once every girl has a chance to stay in school until at least 14 years of age, TFR will drop by more than half.
That sounds so much better and so much more humane (sarcasm).
