Marine transportation refers to the movement of goods and people over water using various types of vessels, such as ships, boats, and ferries. This mode of transport is essential for international trade, as it allows for the efficient shipping of large quantities of products across oceans and seas. Major ports, like Port of Shanghai and Port of Los Angeles, serve as key hubs for these activities. In addition to cargo transport, marine transportation also includes passenger services, such as cruise ships and ferries, which connect coastal communities and provide leisure travel options. This system plays a vital role in the global economy and supports tourism in many regions.
