How's this for a Sustainable project?
If we are to be a sustainable planet, 2000m2 is about as much arable land we all have per year, each, for our food supply. Today, an average Swedish uses about twice as much arable land per year. This is not sustainable.
The goal is to be able to produce all food for one person for a year- with only 2000m2. Good, healthy and sustainable. And I was lucky enough to visit them recently. This is a great project to follow!
