Answer: D) 11 million pounds of CO2
That's right, the Olympic torch relay, which will pass through 23 cities during a global sweep that includes stops in London, Paris, San Francisco, Bangkok, and Islamabad among others and cover over 85,000 miles, will result in the emission of 11 million pounds--or 5,500 tons--of CO2 into the air. That's mostly because the torch is making its way around the world by plane in a custom painted Air China 330, which uses 5.4 gallons of fuel every mile. Bottom line: that's a lot of CO2 just to have a torch relay consistently marred by protests along the way.
