The Green Game Trail is the perfect way to meet people and talk with them about Sustainable Development. Politicians are under influence and teaching people about what is fair for the planet will take years. So we tried a one-to-one approach. No speeches, but a quizz, a contest to provoke our citizens and show them that they are the problem and the solution. This episode of our Green Tour starts in Sevilla (Spain) to join Salamanca, crossing stunning places and nice characters.
