Seaside resorts, which appeared at the end of the 18th century, first for medical reasons and then for purely idle reasons, were English inventions that first spread over the European coasts and then worldwide. Today, they represent a particularly important tourism issue. However, European coastlines, from the English Channel, the Atlantic to the Mediterranean Sea, are currently in a situation of great vulnerability to environmental change. The rise in sea level and the accelerating rate of coastal erosion and submersion are tangible signs of global warming, which in turn is leading to an increase in certain types of pollution that have been contained until now. There is now talk of the disappearance of some of these stations and the relocation of others, where possible. Submersion, erosion, pollution, stronger storms: a whole model of tourism seems to be under threat of extinction. The study cases developed will be limited to Europe, with a few exceptions, and are taken mainly in France.
