Passage One
At some 2,300 miles in length, the Mississippi is the longest river in the United States. At some 1,000 miles, theMackenzie is the longest river in Canada. But these waterways seem mute in comparison to the world’s two longest rivers—— the Nile and the Amazon.
The Nile, which begins in central Africa and flows over 4,100 miles north into the Mediterranean, hosted one of theworld’s great ancient civilizations along its shores. Calm and peaceful for most of the year, the Nile used to flood annually,thereby creating, irrigating and caring new topsoil to the nearby farmland on which ancient Egypt depended for a livelihood.As a means of transportation, the river carried various vessels up and down its length.(9)A journey through theunobstructed part of this waterway today would pass by the splendid Valley of the Kings, where the tombs of many of theseancient monarchs have stood for over 3,000 years.
(10)Great civilizations and intensive settlements are hardly associated with the Amazon,(11)yet this 4,000-mile-longSouth American river carries about 20 percent of the world’s fresh water— more than the Mississippi, Nile, and Yangtze combined.Other statistics are equally astonishing. The Amazon is so wide at some points that from its center neither shore
can be seen. Each second, the Amazon pours some 55 million gallons of water into the Atlantic; there, at its mouth, standsone island larger than Switzerland. Most important of all, the Amazon irrigates the largest tropical rainforest on Earth.
