Minu Pauline, owner of the Pappadavada restaurant, in Kochi, southern India, was moved to combat both food waste and hunger after seeing people scavanging waste food from bins, so she put a fridge outside her restaurant. The fridge nicknamed nanma maram, meaning tree of goodness began as a place people in need could pick up excess food from the restaurant. It's now become a community hub, with people from across town donating to it and the idea is being implemented around the world.
