      "The visionary engineer Paul MacCready has made an arresting
      calculation: Ten thousand years ago, human beings (plus their domestic
      animals) accounted for less than a tenth of 1 percent (by weight) of
      all vertebrate life on land and in the air, Back then, we were just
      another mammalian species, and not a particularly populous one (he
      estimates eighty million people worldwide). Today, that percentage,
      including livestock and pets, is in the neighborhood of 98!"

      Currently our pets and livestock outweigh us about 3 to 1.

      Electric Vehicles" in _The Hydrogen Energy Transition_.
