America’s Finite Future?

Near the beginning of “Saturday Night Fever,” John Travolta’s Tony Manero, frustrated that his boss thinks he should save his salary instead of spending it on a new disco shirt, cries out, “fuck the future!” To which his boss replies: “No, Tony, you can’t fuck the future. The future fucks you! It catches up with you and it fucks you if you ain’t prepared for it!” Well, I don’t know if you’ve noticed, but America has morphed into a nation of Tony Maneros.

Energy and Human Evolution

Life on Earth is driven by energy. Autotrophs take it from solar radiation and heterotrophs take it from autotrophs. Energy captured slowly by photosynthesis is stored up, and as denser reservoirs of energy have come into being over the course of Earth’s history, heterotrophs that could use more energy evolved to exploit them, Homo sapiens is such a heterotroph; indeed, the ability to use energy extrasomatically (outside the body) enables human beings to use far more energy than any other heterotroph that has ever evolved.
