The Foamy Rio Tietê
Clip | 4m 40sVideo has Closed Captions
Mega-droughts in Brazil lead to toxic foam polluting the Rio Tietê.
Ecologist Greg Asner chases droughts, measuring the effects using 3-D maps. All over the Western Amazon, he's seeing huge loss in tree canopy. The mega-droughts in Brazil are damaging the rivers that fly above the forest and causing problems elsewhere. Because of the drought, there was not enough water to flush pollutants, like this toxic foam, out of the Rio Tietê.
