Ruined is such a loaded word. I'm guessing it did not meet the expectations of these people you've met. National parks are places where nature is left to their own accords, and that happen to allow easy access for people to see such mostly-unspoiled nature. Nature does not care what you think about it. It is not constant, but rather changing and evolving. Sometimes, points in time in that evolution are glorious and pleasing. At others, they may seem mundane, or even repulsive. To force nature to remain in a certain state just reinforces the idea that things don't change. Let's leave that to zoos and botanical gardens, while letting national parks retain as much of their full cycle as feasible. I wonder what this person's thought was about the no-longer-flowing Minerva Terrace in the Mammoth Hot Springs in Yellowstone. Is it ruined as well? As an analogy to putting out forest fires in national parks, perhaps the Yellowstone administration should put in some piping to at least wet these terraces down a bit to save some of their previous glory.
