State Rep. Says Biking Is Not Earth Friendly Because Breathing Produces CO2

I haven't read the book but I find that hard to believe for many reasons.

1. You are going to breathe some anyway, so you need to look at how much more CO2 you give off than if you were just sitting. And they need to compare a typical rider, not Lance Armstrong in competition mode. The bicycle is one of the most efficient forms of transportation ever made, in terms of distance traveled per energy put in. I rode a bike pretty much exclusively in college, and in a flat town, it's less work than walking. Pedal, coast. Pedal, coast. Pedal, coast.

2. If you're going to look at all the CO2 it took to make some asparagus, then you need to be fair and look at all the CO2 it took to make every single component of the car, and assemble the car, and all the CO2 it took to gather and refine the petroleum that's in the tank -- not just the CO2 that's coming out the tailpipe. I'd also be curious how he made his measurements -- like the saying goes, it takes a lot to build a factory to make one can of soup, but after you've done that, the next million cans are pretty easy.

3. I'd also like the see the footprints of more foods. There's probably a 10x, if not 100x, difference between the highest and lowest foods, and as you say, we don't all eat just asparagus.

4. And finally, are you talking about the entire bus, or just one rider's worth? The good Rep. Orcutt is talking about biking versus driving a car, and we all know that a bus with 60 people gives off less CO2 than 60 people driving.

If you're familiar with the book, I'd be curious to know the answer to any of those questions.

In any case, the representative is full of shit. When I'm walking my kid to school, and we get to the door, I can smell the exhaust of the dozens of cars sitting there. It does not smell like that from an equal number of people breathing.
