We live in an age of global mass tourism. Last year, the UN estimated 1.5 billion people travelled to another country. While many places depend on tourism for income and employment, it can come at a significant environmental and social cost.
We take a tour of Dubrovnik in Croatia, which has the highest tourists-to-locals ratio in Europe. The city is using perks and penalties to keep both local people and visitors happy. Also we paddle and cycle around Copenhagen in Denmark. They are rewarding eco-friendly actions to encourage better tourist behaviour.
