Palau, a Pacific island-nation, has seen a massive growth in tourist numbers in the past three years.
The Palau Legacy Project, a tourism marketing body that works alongside the government, recognised that without action, it would be too late to protect some of the most unique parts of the country, such as the UNESCO World Heritage listed Rock Islands.
The challenge was to find a balance between encouraging tourism without compromising the environment.
However, the costs of environmentally wasteful, destructive behaviour are difficult to feel on an individual level. Those costs aren't the result of any one person's careless actions but of aggregate actions, not felt until months/ years afterwards.
