This isn't true. You can channel people into the behaviors you want by making them easier; it's not an all-or-nothing "no matter what our environment is like, 3% of visitors will leave litter" situation. There are many things you could do to reduce environmental damage while accommodating more visitors:
- You could put handrails around the trails. People aren't supposed to leave them anyway.
- You could station trash cans along the trails. This makes it much easier to throw your trash in an appropriate place.
- You could establish fire pits in which it was officially OK to have fires.
- You could patrol the trails. This doesn't work well when hikers are rare, but it scales beautifully as they get more common. Or, you could have a stationary security presence in problem areas.
- You could blaze new trails.
Everything I've listed except trail patrols is something I've personally seen in some areas. (Full disclosure, I'm actually just assuming that new trails get blazed from time to time. I have, however, personally experienced trails being radically reworked between visits.)

Why?
