About this episode

Dean Spears discusses his book 'After the Spike' and the implications of a declining global population.

Dean Spears is the author of the new book After the Spike about why the world's population will peak this century. We discuss why demographers are pretty certain that worldwide population will start to decline around 50 years from now, whether or not we should be concerned about it, and what we can do if we think it's not necessarily a good thing.
