This river originates in Western China's Qinghai province mountains. It drains into the Bohai Sea. This waterway has been affected by natural disasters such as floods and changing course killing millions. Building dams around it has reduced flooding and saved lives.

The Yenisey is one of the 10 longest rivers in the world, and it is the longest to discharge in the Arctic. It stretches 5,539 kilometres from its source in Mongolia to the Arctic. Yenisey drains most of its water in central Siberia as it continues towards the Kara Sea.
Its bank has been home to many nomadic people, such as Ket and Yugh. The Taimyr family graze here during winter. Unfortunately, it is heavily polluted by radioactive discharge from a plutonium factory in Zheleznogorsk.

The Mississippi, Missouri, and Jefferson are among the world's longest rivers. This system is the fourth longest, stretching through 31 states in the United States and two Canadian provinces. The origin of the Mississippi is Lake Itasca in Minnesota which drains into the Gulf of Mexico. The Jefferson is its farthest source. The combination makes up Mississippi–Missouri–Jefferson river system.

The Yangtze is the longest river in Asia and the third longest in the world. It is also the longest waterway to flow in one country. One-third of the Chinese population lives in the basin of Yangtze and uses the water for its everyday life. The government has identified its source as the Tuotuo tributary in the Tanggula Mountains.
However, new data show the Jari Hill from where the Dam Qu tributary originates as the source of the mighty Yangtze. More tributaries feed the watercourse as it wades through the Chinese mountains. It finally discharges at the East China Sea at Shanghai.

The Amazon has its source in the Andes mountains in South America. As the name suggests, this watercourse runs through the Amazon forest. It cuts through seven countries draining into the Atlantic Ocean. Although it's not the longest on earth, it has the largest drainage basin by width, which sometimes reaches up to 120 mi (190 km).
