I've been thinking of just this idea ever since I returned to Canada. We lived in Tokyo for six years. I saw so many people growing (not food) in so many containers, since no one has any 'land' to use. When I came back to North America all I could see was the disrespectful waist of land. What are we doing as a culture growing this grass stuff? At the time the food crisis was already looking for me. I've been waiting for it so happen since I was in university.
Now all I can think of is the Victory Gardens during the war and looking at what others are doing.

I am walking my talk and almost the entire lot which my rental house is on is being used to grow food or healing flowers. Since it is a rental and we moved in in April we have not used up every inch. But we sure worked hard at making it productive. Its amazing. Thank goodness for the Japanese self-sustainable farmer who took us under his wings.

Now I have to learn to get this message across.
