Depending on your brain structure and circumstances travel can have a different effect on different people. I have some form of 4D memory - I can go back to any place i’ve seen, including my dreams and spend time there any time I want. The sights, the smells, the sounds. As a result I don’t feel a need to travel to the same place twice, but I do miss the people and the food at every place I go. So in a way with every trip, I leave a piece of me behind and I miss it, until no place can ever be perfect for all the precious people it’s missing. Others I know see travel as therapy, as an escape. They photoshop the people out of their photos to keep the place pure and go back to it by looking at albums. They enjoy the experience of being in the warm water of a favorite beach, and would do anything to go back there as often as possible. Travel should not be limited, but there needs to be an international protocol of conservationist behavior that we all abide by whenever leave home. More people have the means to travel every year, and likely a safe thing to do would be to print a protocol brochure/terms of travel if you will, and request agreement from everyone as a part of the ticket purchasing or customs process.
