In fact, if humankind was really as dumb as the fans of DPS would have us believe, we wouldn't be around today to hear their doomsaying, because Homo sapiens would have been wiped out during vastly larger environmental swings (in and out of ice ages, for example) in our past, than those expected as a consequence of the burning of fossil fuels to produce the energy that powers our world — a world in which the human life expectancy, perhaps the best measure of our level of «dumbness» or «smartness» — has more than doubled over the last century and continues to grow ever longer.

It's a profound thought to ponder; while it doesn't mean there are actually more species out there, it's certainly a humbling thing for us know - it - all homo sapiens to consider.
