3Boracay, Philippines

Boracay is famous for its powdery white sand and vibrant nightlife. This small island in the Philippines was once considered a tropical paradise. However, overtourism led to environmental degradation, with wastewater polluting the sea and uncontrolled construction damaging the landscape.
In 2018, the Philippine government shut down Boracay for six months to clean up and restore its environment. Although it has reopened, restrictions are in place to control the number of tourists and preserve the island.
