About Rivers of the World
The rivers of the world sustain us. We build our cities on them, we get our drinking water from them, and sometimes, we even use them for recreation. The major rivers of the world - like the Nile, the Amazon, or the Yangzte - amaze us with their length and volume. However, rivers don't have to stretch for thousands of kilometers in order to be impressive (like the "River of Five Colors"). Unfortunately, some rivers of the world are heavily polluted and in need of rehabilitation.
