The Times Online tells us that walking to work is a bad idea. A very bad idea as it increases global warming more than driving to work!The article compares driving 3 miles to work versus walking 3 miles to work. They conclude that "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."
They base the emissions not on your possible problems with flatulence but rather the energy used to process your food, transport and store it.
The article misses one important point here. I think it would be extremely unlikely for a person to eat 100g more beef simply because they walked to work. I believe eating habits are based on much more than walking or driving.
So by driving you use the energy of the 100g of beef, plus the energy of the automobile, plus you turn into a fatso, plus you need more medical care. Driving to work certainly does not reduce anything.
Finally they start to make some sense: "We have industrialised our food production. We use an enormous amount of processed food, like ready meals, compared to most countries. Three quarters of supermarkets’ energy is to refrigerate and freeze food prepared elsewhere."
Not only have we industrialized our food production, we have industrialized our food! Most of what we stuff in our mouth's isn't really food at all, but some fancy mixture of chemcials with a dash of "food" added by some factory.
Start eating real food, stop driving and forget what nonsense you read in the newspaper!
