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

terbeaux writes "The fact that Rep Ed Orcutt (R — WA) wants to tax bicycle use is not extraordinary. The representative's irrational conviction is. SeattleBikeBlog has confirmed reports that Orcutt does not feel bicycling is environmentally friendly because the activity causes cyclists to have 'an increased heart rate and respiration.' When they contacted him he clarified that 'You would be giving off more CO2 if you are riding a bike than driving in a car...' Cascade blog has posted the full exchange between Rep Ed Orcutt and a citizen concerned about the new tax."

      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.

    Weeds are plants in the wrong place. And pollutants are chemicals in the wrong place. Dihydrogen monoxide certainly can be a pollutant. In times of flood for example. Or in my whisky.

    Maybe the people who set up this vox-pop trap weren't as clever as they thought they were.

    It's bad enough when people with degrees in Law or Political Science or Business Administration try to legislate on scientific questions. What's even scarier is the fact that this guy received an A.S. in Forestry from the University of Maine, and a B.S. in Forestry Management from the University of Idaho. Which I'm sure is a lot less biochemically rigorous a field of study than, say, Botany, but someone with that kind of credentials ought to have a better understanding of environmental science than he shows.

    That's the last of our problems- we'd all be dead within 72 hours or so. CO2 is required to make the human respiration system work, the breathing reflex is triggered by too much CO2, not by a lack of oxygen, this is why hyperventilating before holding your breath can make you pass out, you scrub lots of CO2 out of your system and then run out of O2 before your brain forces you to inhale. This is also the mechanism behind Cheyne Stokes respiration, where high altitude climbers don't breath enough while they sleep.

    Erradicate all CO2 and you have to consciously breath, on purpose - if you forget, or fall asleep, you're dead.

    I say we cut down the CO2 emissions... with a herring.

    Most of the calories you eat are being made with lots and lots of fossil fuels both for fertilizer and even basic processing like separating wheat from chaff.

    Sure a car is worse, but cyclists and all humans at this point are increasing net CO2 just by eating.
