Walking Causes Global Warming

Ya, Rly:
Walking does more than driving to cause global warming, a leading environmentalist has calculated.

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.

People don't eat all of their calories in beef. I like beef a lot, but I eat very little beef in relation to the rest of the food I eat. It'd be interesting to see something more diversified in that aspect.

So would I. 100 grams is about 1/5 of a pound steak or burger, not exactly a meal. Other things that are about 180 calories:

1 oz of walnuts
3 jumbo shrimp
1 small croissant
... endless others

Yeah, it would be interesting if nothing else to see what it takes to produce other foods.
