Series 1: Episode 4

Simon travels through three of the world’s most extreme environments: the salt flats of Bolivia, the Brazilian Pantanal and Paraguay’s Chaco Forest.\n\nIn Bolivia, Simon meets a family who make a living carving salt from the vast white expanse of the Uyuni salt flats. They're so huge that it's said they can be seen from the moon. He learns that beneath the salt could lie huge reserves of lithium, the metal so crucial for the batteries that will fuel the next generation of electric cars.\n\nCrossing into Brazil, Simon visits the world’s largest wetlands, the Pantanal, and has a close encounter with South America’s apex predator, the jaguar. Drought and fire threaten the Pantanal, but so too does excessive flooding, and Simon meets a farmer who has spent years building dams to hold back the rising waters and save his family farm.\n\nThe last leg of this journey takes Simon into the little-visited Paraguay, where he meets a unique community which, despite their small numbers, has had a huge impact on the economy and environment of the country. Mennonites originally hail from Europe, but they have spread throughout the world. In Paraguay, many live in ultra-conservative communities and eschew many of the trappings of the modern world. They drive around in horses and carts and speak their own language, known as Low German.\n\nSimon visits a school where traditionally clothed children are drilled in Bible texts and there are no smartphones to be seen. But the Mennonites have been hugely successful farmers, embracing modern methods where necessary to found vast cattle ranches and soy farms. They have chopped and burned huge areas of the Chaco, the unique dry spiny forest, which is twice the size of Spain and dominates the centre of the South American continent.\n\nPerhaps inevitably, this economic miracle, which has turned Paraguay into a major player in the global food market, has had its victims, and Simon ends this leg of his journey with the Ayoreo people. Following a history of persecution and having lost much of their land, the Ayoreo now mount armed patrols to defend what remains. Others have given up the modern world altogether and returned to the hunter-gatherer lifestyle of their parents and grandparents, living in the harsh dry forests of the Chaco.
