If the shamans stop dancing and life in the rainforest loses its balance, the sky will collapse and crush everything beneath it. This story has been passed down in the Brazilian Amazon by every generation of Yanomami. But greed for gold is polluting rivers and poses a threat to the Yanomami. Their shamans are dying as the earth warms. Davi Kopenawa, Yanomami shaman and spokesman, has been fighting these threats for more than forty years. When Brazilian President Bolsonaro announces that industry will be allowed to set up in the Amazon – on Yanomami territory – Davi sets out on a journey around the world to defend his people against endless colonisation. Can he convince white people that the Yanomami aren’t the only ones who will be destroyed if the sky collapses?
