The American showman, P.T. Barnum, is credited for saying, "There's a sucker born every minute." Maybe he said it, maybe he didn't. But one thing he knew well was the gullibility of the general populace.
Apparently a bunch of folks operating under the name 3 Degrees Inc. have updated Mr. Barnum's observation for this century. They are behind an amazing little scam, The Climate Passport. Correctly surmising that self-loathing libs flying through San Francisco's airport are a target-rich environment for their moneymaking gag, they placed their first kiosk in Terminal 3 at SFO. The guilt-ridden greens passing by are able to stop, calculate the carbon footprint of the flight they are boarding, and then pay a duty to offset the environmental degradation they are going to create.
There is no underestimating the intelligence of your run-of-the-Mill Valley trust-fund hippie. They are actually going for this dopey deal.
