Are terrible tourists taking over? It seems like every day comes with a fresh new example of travelers behaving badly — whether they are destroying ancient artifacts, punching Disney employees, or putting their bare feet on the armrests on planes.

But whether this is simply a result of more people traveling than ever before or the 24-hour news cycle, some destinations are fighting back. While it started with selfie-stick bans and caps on visitors, more and more places around the world are now instituting “tourist pledges” — waivers travelers must sign promising to be on their best behavior and to practice responsible tourism.

Generally, these pledges ask visitors to travel respectfully by not littering, following local rules and customs, and avoiding risks. While not all of these pledges are mandatory, the fact that they have become a thing is telling.
