Book Description
Human ingenuity has created three great canals in different locations on our planet. Each of these transformed the country and the world in its own way and time. The oldest canal to be constructed was the Grand Canal, an important Chinese waterway, connecting Suzhou and Beijing, a distance of 1,104 miles (1,776 km). This is the longest artificial canal in the world and is a UNESCO World Heritage Site. Not as well known as the other great canals, this important waterway enabled merchants to bring grain and other goods over this long distance so that merchants could transport goods throughout the kingdom. The Grand Canal was first constructed by Fuchai, King of the State of Wu, whose capital is in present-day Suzhou, in 486 BCE. Over the centuries, the Grand Canal was expanded and rebuilt and is still in use in China. The second oldest canal was constructed in ancient Egypt when the waterways of the Nile River were expanded to ease shipping goods throughout the country. Much later, modern engineers reconstructed the Suez Canal, an effort that required much ingenuity and effort to bring this project to fruition. This waterway, at 120.1 miles, was opened in 1869, transforming modern shipping of goods by reducing the journey by between Britain and India by 4,500 miles. Up to this time, ships had to travel around Africa's Cape of Good Hope or past the tip of South America (Magellan or Drake Passages) to reach the other side of the world. Both of these points are dangerous with many ships lost at sea. The Suez Canal completely bypassed this difficulty. However, the territorial disputes and enmities between the Egyptians and Israelis soon saw conflict across these placid waters. In each of the major wars fought between these two countries, the passage of mercantile ships through the Suez Canal became dangerous. Once peace was established between Egypt and Israel, maritime traffic resumed and the world benefited from that peace. Today, there is peace between these two countries, and I recount the instances when I sailed on the Suez Canal. The last canal to be built was in Panama, making travel between the Atlantic and Pacific oceans possible. French engineers tried to construct this canal but failed for various reasons. The United States then took over the project and in vast effort, saw the project to completion. Two years of preparatory effort was necessary to construct infrastructure for the thousands of workers who would toil in the earthworks being moved to create the Panama Canal. A notable effort was addressing the lethal malaria, yellow fever, and other tropical diseases endemic in this country. In the end, yellow fever was completely eradicated from Panama, though malaria cases, though low, continue to be present. The Panama Canal is 50 miles in length and opened on 15 August 1914. Today, thousands of ships, carrying passengers and goods, travel through this, and the other canals, thereby transforming our world.
