The Amazon River in the Sky
A crucial link that sustains the Amazon rainforest is at risk of running dry.
High in the Andes Mountains, the mighty Amazon River begins. It trickles from glaciers and oozes from mountain wetlands. It gains momentum and volume and feeds into clear streams and muddy rivers that pass through high cloud forests and lowland valleys. The torrents of the waters carry nutrients through the vast Amazon River basin, some 4,000 miles across the rest of the South American continent.
At the same time, in the rainforest and delta estuaries, another, more ethereal—but no less essential—river is forming.
A single large tree in the Amazon rainforest can transpire about 264 gallons of water per day.
