Most adult humans suck and will never learn. No matter how much you educate them or invent new products to make it easier to haul out trash or dog poop.Most humans have that mentality "Don't worry someone will pick it up". People will leave trash behind even if its on accident, water bottle falling out of a backpack, a wrapper getting taken away by the wind. The only people that get it are the ones that truly love the outdoors and will pick up trash when they see it. The best way to start is with the children. Teach them and instill it in there minds.
