With overtourism becoming a growing concern the world over, one tiny island in the Western Pacific has taken action to protect its future generations from the damage caused by overseas visitors.
Palau has become the first country in the world to ask visitors to sign a conservation pledge on entry, which is stamped in their passports.
The 160,000 tourists who each year visit Palau now have to make a compulsory promise, directly to the island's children, before they can enter the island of 20,000 inhabitants.
The pledge, which aims to preserve the country's vibrant culture and the beauty of its natural environment, was considered necessary after careless behaviour from visitors started to erode Palau's pristine environment.
