Angry Planet S04E02 - River of Doubt

In 1914, U.S. President Theodore Roosevelt became the first person to navigate Brazil's "River of Doubt." The Angry Planet team returns to follow in his wake and investigate the changing climate in this remote part of the Amazon wilderness.

Deep in the Amazon, George is determined to retrace a legendary expedition and witness how deforestation and climate change are affecting one of the earth's most critical ecosystems. US president Theodore Roosevelt led an expedition down an uncharted river, losing several men and boats along the way. Today George is hoping to unearth one of Roosevelt's long-lost boats.
