Riding a bike won’t stop … many other dire predictions from happening in our lifetimes, but maybe if some cities face the climate, energy, and transportation realities now they might survive, or even prosper—although the idea of prospering seems almost morbid, given that so many unsustainable cities will inevitably flounder through droughts, floods, unemployment, and lack of power. I expect some of the cities I’ve ridden around to more or less disappear within my lifetime—they’re resource hogs and the rest of the continent and the world won’t put up with it for long. I don’t ride my bike all over the place because it’s ecological or worthy. I mainly do it for the sense of freedom and exhilaration. I realize that soon I might have a lot more company than I have had in the past, and that some cities are preparing for these inevitable changes and are benefiting as a result.
