The Panama Canal (Spanish: Canal de Panamá) is a major ship canal that traverses the Isthmus of Panama in Central America, connecting the Atlantic and Pacific Oceans. The construction of the canal was one of the largest and most difficult engineering projects ever undertaken. It has had an enormous impact on shipping between the Pacific and Atlantic oceans, obviating the long and treacherous route via the Drake Passage and Cape Horn at the southernmost tip of South America. A ship sailing from New York to San Francisco via the canal travels 9,500 kilometres (6,000 mi), well under half the distance of the previous 22,500 kilometre (14,000 mi) route around Cape Horn.
Despite having enjoyed a privileged position for many years, the canal is increasingly facing competition from other quarters. Although remote, speculation continues over a possible new canal through Mexico, Colombia or Nicaragua that will be capable of accommodating post-Panamax vessels, and two private proposals for a railway linking ports on the two coasts.
Critics have also voiced their concerns over the planned increase in canal tolls, suggesting that the Suez Canal may become a viable alternative for cargo en route from Asia to the U.S. East Coast. Nevertheless, demand for the Panama Canal continues to rise.
The increasing rate of melting of ice in the Arctic Ocean has led to speculation that the Northwest Passage may become viable for commercial shipping at some point in the future. This route would save 9,300 kilometres (5,800 mi) on the route from Asia to Europe compared with the Panama Canal, possibly leading to a diversion of some traffic to that route. However, such a route would still hold significant problems due to ice, as well as unresolved territorial issues
Water issues
A significant problem is the decreasing average amount of water in Gatún Lake, caused largely by deforestation. 52 million gallons of fresh water from the lake are drained into the sea by the locks every time a ship transits the canal;[29] and although there is sufficient annual rainfall to replenish the water used by the canal in a year, the seasonal nature of this rainfall means that the water must be stored from one rainy season to the next. Although Gatún lake can store some of this water, the rainforest has traditionally played a major role by absorbing this rain, and then releasing it at a steady rate into the lake. With the reduction in vegetation, rain flows quickly down the deforested slopes into the lake, from where the excess is spilled out into the ocean. This results in a shortfall of water during the dry season, when there is comparatively little water flowing to the lake to replenish it. Deforestation also causes silt to be more easily eroded from the area around Gatún Lake and collect at its bottom, reducing its capacity.

Strategic location of the canal & its trade importance create political and military issues.
He who posesses the canal holds an advantage if war is nessicary, as it is a passageway that avoids thousands of miles of detour.

It develop right into a slip of the tongue. He for sure meant to declare the Suez Canal. I word that no person has even stated the Suez. call-calling in ordinary terms illustrates your loss of sparkling innovations.
