Palau is the first nation on earth to change its immigration laws for the cause of environmental protection. Upon entry, visitors need to sign a passport pledge to act in an ecologically responsible way on the island, for the sake of Palau’s children and future generations of Palauans. The stamp, which outlines a promise to help Palau protect its environment, acts as an agreement on entering the small country. Palau is is the 13th smallest nation in the world but it attracts almost eight times its population in tourists each year. The hope behind the campaign is to preserve the vital incoming economic value of tourism but also create a better understanding of small changes that tourists can do that help preserve the environment too.
