Much of the metro area's success as a petrochemical complex is enabled by its busy man-made Houston Ship Channel. Because of these economic trades, many residents have moved to the Houston area from other U.S. states, as well as hundreds of countries worldwide. Unlike most places, where high fuel prices are seen as harmful to the economy, they are generally seen as beneficial for Houston, as many are employed in the energy industry. Baytown, Pasadena, La Porte, and Texas City have some of the area's largest petroleum/petrochemical plants, though major operations can be found in Houston, Anahuac, Clute, and other communities. Galveston has the largest cruise-ship terminal in Texas (and the 12th-largest in the world). The island, as well the Clear Lake area, are major recreation and tourism areas in the region.
