Edited photographer note: In Papua New Guinea, traditional forms of marine­ resource management include setting up ‘taboo’ areas at certain times, when access to fishing or the collection of shellfish is prohibited. Many reefs are also so remote that they are seldom visited by fishermen and you will find schooling fish in abundance. When you as a traveler and explorer are lucky enough to find pristine places like these, it is important to keep in mind that any of your actions will have a definitive and irreversible impact on your surroundings and yourself. It’s not a question of if you are leaving a “footprint” behind, but how deep. Even just taking a picture and publicizing the location could lead to negative or positive consequences for the environment or the native people’s way of life. Sustainable travel has mostly to do with respect, consideration and foresight.
