Political action is not the road to effective change. The way to really change society is to start with yourself, your own groups, your own businesses and work your way out. The further away from your self you get, the less of a chance you have of changing anything.
This is how I have cut my grass, for the past year or so. Its actually less work overall, no nasty smells, no gas or motors to deal with and you get a moderate workout. Its just as fast, if not faster, than cutting the grass with a gas mower, if you keep the grass cut regularly. (Filmed on 2012-08-19)
