The main character of the story has a full week of holidays which he enjoys while sightseeing. When he comes back and shares his experiences, a piece of coral taken from the sea makes his friends tell him about the need to follow a model of sustainable tourism so that he can discover new cultures and lifestyles while he takes care of the environment, promotes local commerce and contributes to the local development. When his next holidays arrive, his idea of tourism has changed and he enjoys a series of activities which are more respectful and which stick to his new beliefs.
