I am actually of the opinion that national parks should be more protected or have significant increases in price and/or limited visitors. We went to Rocky Mountain National Park on what happened to be a major holiday weekend. We actually didn't plan on doing so, but we were looking for something to do while already on vacation there and decided to hit up some of the trails on a day we hadn't planned anything. The park was so unbelievably packed it was miserable at some of the popular trails. Hour long bus rides to get to the trail, tons of cars, and tons of hikers. I spoke candidly with some of the volunteers and park rangers there, and they agreed that something needed to be done to limit visitors and were certain it would be coming sooner than later.

Everywhere you could look you could see damage to the park. From people swimming in the mountain lakes, going off trail, cars providing pollution and noise and killing animals, etc. The volunteers at the park were exhausted. And I'm pretty sure someone hit and killed a black bear with a car on the weekend we were there. People were just moving through the park like cattle at the mall.
