Yes. Also we should work hard to bring simple and easily available solutions. Yesterday I spent half of my saturday trying to get rid of some waste in the right way.
Between us, I now understand why there is so much waste left in the wilds, because when you want to do the right thing, the system will give you a hard time. But throwing the stuff out is free and simple.
