A harbor is a sheltered area along a coastline where ships and boats can dock safely. It provides protection from rough waters and harsh weather, allowing vessels to load and unload cargo or passengers. Harbors can be natural, formed by the geography of the land, or artificial, created by human engineering. Many harbors are equipped with facilities such as docks, warehouses, and fueling stations. They play a crucial role in trade and transportation, connecting different regions and countries. Famous examples of harbors include the Sydney Harbour in Australia and the Port of Los Angeles in the United States.
