It seems to me that the closer one is to a road, the greater the likelihood you will see cast-aside tissues. I’m no fan of any garbage in the wrong place, but tissues cast aside in places that are World Heritage sites, jewels of national park systems of any nation, are just plain unforgivable. Don’t they know they take 2-3 years to decompose? (And probably longer in dry environments like this one in Zion.) It’s not as if they get any better-looking with time. Who do they think is going to clean them up?
What could we do to change this horrible – and I hope unconscious – habit? Nothing takes me out of my deep appreciative and serene meditative state in the wilderness more than seeing these ugly reminders of unthinking carelessness.
