Everything I have read about The Wave which could also parallel the other locations you mentioned are the up/downside to the Internet and Instagram. It is a different world nowadays and there is no going back. The good news is that as more people visit these wonderful places, I am hopeful the outdoors will effect peoples attitudes about everything. The bad news is that there will always be 10% of the visiting population that trash/thrash and disregard the beauty of any particular place.
All I know, is I am going to keep exploring.....:)
