Use green 'waste' and foodscraps in worm farms and/or compost to grow food. Remember : waste is a state of mind. Perceive waste as a resource and then use it and it is no longer waste. Its that simple.
Do this on any land that is under-utilised (ie not growing food). Eat it, give it away, sell it - doesn't matter much. After air and water, food is the 3rd most essential need for human life. Spread the food and spread the love.
Research, practice and encourage others to do the same!
