Yeah, the most popular parks (Rockies, Yosemite, Yellowstone, Zion, etc.) are typically also the most impacted. I think Zion's shuttle program is a good thing, and the Rockies is one of the worst that I've visited in terms of traffic and impacts. Yosemite at least has the valley shuttle, and outside of the valley it's not so bad. More and more places are implementing permit and lottery systems. It's a tough job =/ Private/NGO nature preserves have their place, but I think public access for parks is also a big part in cultivating an appreciation for nature. Not everyone is going to "get it", it's true, but some will. How else would you inspire the next generation of environmentalists, if they never get to experience what it is that's even worth protecting to begin with?
