You are right @leeart! A simple act like this could give a great impact to our environment. This is somethings that everyone should participate about.

I think proper garbage disposal should be taught in schools again and again. I see kids all the time without care throwing things everywhere. If you ask them nicely to pick it up they'll look at you like you with contempt then ignore you.

That's quite true but not all the kids does. But you are right about teaching stuff like this at school. Kids could easily adopt it and carry the good practice when they grow old. But facing the reality now, it is the older people who are doing such terrible things like this without even care.
