Amazonia´s flying rivers – no forest, no water

Interesting and informative documentary: The Amazon rainforest is not only the earth’s green lung (absorbing and storing carbon dioxide from the air and converting it to oxygen) it is also its air conditioner: intact forests suck in rain clouds from the Atlantic and evaporate water. In this way they cool the earth. Without forest, no water: if more and more forest disappears, this phenomenon of ‘flying rivers’ acting like a gigantic water pump can no longer exist. Scientists, politicians and environmental activists explain the fragile balance.
