Also, microbeads. Shit is crazy.
Take it or leave it, but the outdoor enthusiasts I know are more environmentally aware than any typical city dweller I know.
We used to have the largest trail maintenance/clean up/volunteer days in North America just outside of Calgary. Hunters, off-roaders, campers, etc. Built bridges, installed culverts, re-routed trails away from fish spawning grounds. And picked up garbage. Lots and lots of garbage. The people who spent considerable time and money doing the work? Mostly "right wing dolts". The occasional users of the back country who left their shit (sometimes literally) everywhere couldn't be bothered to help. Recycling, thank god, has been made quite convenient in city centers, but devoid of that convenience many people revert to lazy shit stain habits.
My point? Lets not make sweeping statements.
