7. Palau: The Eco-Pledge Requirement

The small Pacific island nation of Palau has implemented a groundbreaking conservation initiative: the "Palau Pledge." Upon arrival, all visitors must sign an oath stamped into their passports, promising to act in an environmentally and culturally responsible manner. This unique, legally-binding pledge, alongside stringent environmental regulations on marine life and pristine natural sites, reflects Palau's commitment to protecting its delicate ecosystem and culture from tourism's potential harms, prioritizing sustainable practices over sheer numbers.
