i live in Tasmania, people here are already like that - they help others, take pride in their surroundings and are mindful with nature in a whole and life is pretty stress-free as well.Well if you did, imagine all the waste, pollution and stress on resources you'd stop.
If this was fed into a cycle of eating the useless, a positive green cycle of improvement is obtained.
People would be more enthused to help others, take pride in their surroundings and be more mindful of what they do- lest they gain too many points (lets call them 'Muchie points') and then are harvested to feed those who are useful and a benefit.
