Can anyone explain the population reversal? There's vague references to changing fertility rates, but that doesn't explain the reversal. There are complex economic factors at play and so just observed changes to fertility aren't enough to make the prediction of population reduction. For example, does the model include expected advancements in agriculture, or does the model assume there is some challenges in growing our food supply? Also, China used to have a one-baby policy but I don't think that is still in effect. Does the model include that?
These kinds of models are pretty to look at but rapidly fall apart when you play with base assumptions. The only way to absorb this data is to have an interactive set of adjusters to base data possibilities.
