The document summarizes artificial islands created in Dubai known as the Palm Islands. It discusses their construction which involved dredging sand from the Persian Gulf floor and using it to shape three palm tree-like islands. The islands add 520 km of new beaches to Dubai and support over 100 hotels, villas, apartments and entertainment centers. While boosting tourism and real estate, the construction damaged marine ecosystems by burying coral reefs and increasing erosion.
