Last week, Slate published an article about how the world population's increase may be slowing down. (If you know me on Facebook or Twitter, you've already seen this.)
So, this week it's not so much a "what if?". Imagine a world in which the population is shrinking, not by any nefarious plot or natural disaster but by ordinary human forces. What would that look like?
What would happen to our schools? Our institutions? Might this be a good thing? What unforeseen problems might occur? (Although, "unforeseen" means connotes things that we wouldn't expect.)
