File that under preventing ecological and climatic stability destroying anthropogenic climate change. The starvation and famine that changing climate risks is foreseen, but at a certain point, we have to acknowledge the world is overpopulated with humanity. We can't support rising living standards (and fossil fuel, water, food consumption) of seven-and-half billion souls, much less any sort of number projected for the future. I'd figure 1970s levels of world population at just above three-and-a-half billion souls was at or just above any reasonable sustainable maximum. People need to stop having so many babies, we can't provide sustainably for the number of souls walking the planet that we have already.
