What can be said, is that once you have looked into, across, along, and over the Grand Canyon you will be changed. If you were unsure of your significance this experience should resolve your understanding. The rock at the bottom of the canyon is plus or minus a billion years old. The 'new' rock at the top, the stuff you walk on is 250,000,000 years old. The river has been flowing and cutting the Canyon for the last 5,000,000 years. About 50 years ago some people dammed and now 'control' the river.
I think the river and canyon will out last the dams, it has already outlasted the men who built them. 'Just sayin'.
