Environmental destruction. Economic degradation. Cultural dissolution. Though these topics dominate the media, they are often ignored in the one place where they wreak the greatest damage: the Amazon. Adventurer and filmmaker Reza Pakravan joins journalist Phillippa Stewart to investigate the perils faced by the Amazon, and to experience the greatest rainforest on earth in a unique and breathtaking voyage along the Transamazonian Highway. Travelling the road by bicycle and the river by boat, they discover the fragility of "the lungs of the planet" and the laborious lives of those who call it home.
