Via WorldChanging comes the idea of the hundred mile diet. You only eat produce grown/raised/caught from up to 100 miles away.
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.
With all this globalisation happening and us getting our beans from asia and our spuds from South America and our milk from Africa, what would happen if for some reason we were cut off from the rest of the world, for whatever reason? If our island was quarantined in the morning how equipped would we be to sustain our current way of life?
