I do not agree on the "increasing" part. Developing countries are undergoing the same transition western countries had at the beginning of the 20th century, where the number of children went down from 5+ to <2 like it is today. The UN predicts that the population will stabilize between 11 and 12 billion around 2100. That is much more than today which poses a large challenge, but not an insurmountable one.
