I'm about to increase my carbon footprint by hopping a plane to Las Vegas, and then driving 150 miles or so down to Lake Havasu, where I'll contribute to ozone depletion by spending four days in a golf cart.
Which seems an appropriate time to pass along the above quote. It's from Steven Chu, Obama's Energy Secretary, and it's something you might want to think about as gas prices zoom toward the $4 level. The Obamas WANT you to pay higher prices, because then you'll drive less, and the planet will be saved from the global warming boogeyman. Get it?
That's why the Obama administration has frozen federal oil leases, blocked drilling in the Gulfand in Alaska and thwarted the Keystone XL pipeline. They think expensive energy is good, no matter how much it hurts your personal finances.
The invaluable Victor Davis Hanson has more to say on the subject here.
