The World's Most Famous Rivers Between the Danube's role in
establishing early Eastern European cities and the Ganges' role
in shepherding the souls of the dead to paradise, rivers across
the world have played a critical part in human history and
continue to be a crucial piece of our environment. This Woman's
Day article features a few of the world's most famous rivers,
from the Nile to the Amazon. One of the lesser-known rivers
featured is also one of the most beautiful, the picturesque Caño
Cristales (seen above). Every fall, the river is taken over by
brightly colored algae, turning the water gorgeous shades of
red, orange, yellow, green and blue—and inspiring its nickname,
"river that ran away from paradise." [Image courtesy of
