View Full Version : Walking contributes to GW more than driving

This is on the same level of genius as the "bicycling doesn't save energy" idea. (http://www.cleanmpg.com/forums/showthread.php?t=5312) Will these poor people ever get their heads out of that dark nasty place they've stuck them in?

Food production is now so energy-intensive that more carbon is emitted providing a person with enough calories to walk to the shops than a car would emit over the same distance. The climate could benefit if people avoided exercise, ate less and became couch potatoes. Provided, of course, they remembered to switch off the TV rather than leaving it on standby.

The sums were done by Chris Goodall, campaigning author of How to Live a Low-Carbon Life, based on the greenhouse gases created by intensive beef production. “Driving a typical UK car for 3 miles [4.8km] adds about 0.9 kg [2lb] of CO2 to the atmosphere,” he said, a calculation based on the Government’s official fuel emission figures. “If you walked instead, it would use about 180 calories. You’d need about 100g of beef to replace those calories, resulting in 3.6kg of emissions, or four times as much as driving.

“The troubling fact is that taking a lot of exercise and then eating a bit more food is not good for the global atmosphere. Eating less and driving to save energy would be better.”

Mr Goodall, Green Party parliamentary candidate for Oxford West & Abingdon, is the latest serious thinker to turn popular myths about the environment on their head.

Catching a diesel train is now twice as polluting as travelling by car for an average family, the Rail Safety and Standards Board admitted recently. Paper bags are worse for the environment than plastic because of the extra energy needed to manufacture and transport them, the Government says.

I've been running 50-60 miles a week to do the 26.2-mile Pikes Peak Marathon this Aug 19.

Based on this article, a H2 is way greener and I should be immediately BANNED! :eek::eek::eek:

OK

***or***

We could eat the same amount, walk (or bike) more, and 60% of the population wouldn't be overweight or obese! That's carbon neutral in my book. ;)

What's the carbon cost of sustaining an extra 10lb of body fat? Can we get convert that to gallons-gasoline-equivalent?

There is the fertilizer to raise the feed to raise the livestock animals...some of you could expand that more.

This is all sillier than my Harry Potter Firebolt and its ensuing thread, which was meant to be silly. Sad thing is though that people actually believe this kind of stuff. Write much more and it will get around the web and someone is bound to quote it defending their anti-green positions. :-}

Thinking about this for about 3 seconds...
Who says I already have a car?
Did they think of the CO2 emissions created in building the parking garage where the shops are?
Did they think of the CO2 emissions involved in getting the gas from the oil well into your car?
Do they think people walk the same distance as they drive?
Unless trains run differently now, I think they leave whether or not I have a ticket for it.
Maybe my town has electric trains?

No, I'm delusional. Hauling a ton of metal and plastics here and there in addition to my own weight with a fossil fuel engine that is less than 20% efficient is the better answer.

I'm destroying the planet as fast as I can... the last time I put gas in my car was 3 months ago, and I haven't driven it for a full 2 months (OK, I know this is a car site. I'll try to do some serious work on FE starting in November).

Did you know that it costs a lot more to walk or bike than to drive? I didn't either, but I'm sure we'll find an article proving it!

I'll be driving my car to buy 100g of beef so I can take a walk! :rolleyes: How would that be for killing the environment really quickly! This factoid seems to be coming more from a Vegan or anti-beef perspective than anything else. I'm glad that we are finally becoming more focused on locally produced products for this very reason, including grass fed beef. No added fertilizers other than what the cows and other animals leave in the stalls and on the ground. I still can't figure out how plastic packaged strawberries can be shipped across the country from California, sold in a supermarket, are still cheaper than picking my own at a local farm. Crazy!:p

No way, that's the best possible thing you could post! You're kicking all of our butts.

OK, you would be if walking weren't so terrible for the environment. :rolleyes: Now get out there and burn some gas, you overachiever...

You're the MAN! Great job!

I only wish I lived close enough to everything to not have to drive.

One day! Probably when we retire.

The Journal of Irreproducible Results had a piece (few years ago) on how increasing obeisty had kept XX kilograms of CO2 out of the atmosphere. Their website does not allow me to grab a copy to post here. It was good reading though; perhaps can be seen in your local libraries.
