Every chapter includes different learning materials, quizzes or exercise. You find all activities as an overview on one page for each chapter. Click on the headings of each activitity to start them. Once you opened the activity you can navigate from activity to activity by clicking on the little grey arrows at the bottom of each page. 

You can also use the navigation bar on the left side of your screen. From time to time, where we consider it as useful, we will also provide direct links to following (or even previous) activities or chapters. 

We recommend to start with the introduction to sustainable tourism.
