Did you watch the Discovery Channel's report on global warming last night, hosted by Tom Brokaw? Did you? Good. If you didn't, shame on you (unless, of course, you don't have cable, in which case, this link is for you). Sure, one can always argue that it uses too much energy to watch TV, but that's just downright snarky.
Anyway, besides all of the obvious ways to reduce your carbon footprint so that me and my unborn children won't starve and burn to death in 2050 (Drive less. Drive a more fuel-efficient car. Throw eggs at Hummers. Buy locally produced food. Turn off lights and electronics when not in use. Use low-energy light bulbs. Get those greedy, money-grubbing morons out of the White House.), I couldn't help but brainstorm all kinds of ways that we could live the way we live, only smarter. Here's a solution to the obesity problem and the energy problem: What if the only way you could power your TV was if you pedaled a bicycle for an hour a day? Sure, it's not realistic, but it's an idea.
What we really need is to be more open-minded toward new ideas, and not fear change. Take it from Norbert Wiener, who wrote in The Human Use of Human Beings (in 1950, folks), "We have modified our environment so radically that we must now modify ourselves in order to exist in this new environment. We can no longer live in the old one."
