The "hundred-mile diet"

The hundred mile diet explained here. In Vancouver!

However, on March 21, the first day of spring, we took a vow to live with the rhythms of the land as our ancestors did. For one year we would only buy food and drink for home consumption that was produced within 100 miles of our home, a circle that takes in all the fertile Fraser Valley, the southern Gulf Islands and some of Vancouver Island, and the ocean between these zones. This terrain well served the European settlers of a hundred years ago, and the First Nations population for thousands of years before.

This may sound like a lunatic Luddite scheme, but we had our reasons. The short form would be: fossil fuels bad. For the average American meal (and we assume the average Canadian meal is similar), World Watch reports that the ingredients typically travel between 2,500 and 4,000 kilometres, a 25 percent increase from 1980 alone. This average meal uses up to 17 times more petroleum products, and increases carbon dioxide emissions by the same amount, compared to an entirely local meal.
