The unfortunate problem of reducing birth rates is that you'll inevitably have smaller and smaller working generations supporting retiring, elderly generations. While we should be working to lower the number of children being born, we don't want to create an unsustainable, elderly welfare state. The only solution I could see is to continue increasing the retirement age and encourage lower birth rates (and, of course, this will be a natural process as more and more people move into cities).
Thankfully, most of the growth will be in places where people consume very few resources per person (primarily in Africa and Asia), but the strain on already starving and struggling populations will be terrible.
