 Today I'm going to take you on a bit of a journey around some of the world's tourism hotspots, Spain, Southern Africa and Hawaii. And in each of these places, there's a tension between the money that tourism brings in and the price that locals have to pay for it. To start off with, we are going to focus on Spain and I've got Maria Clara Montoya from the What In The World team here with me in the studio. Hi. Hi. These videos of people being squirted with water pistols in Barcelona are kind of crazy. What are the protesters concerned about?
