The Amazon: Earth's Vital Ecosystem

As a companion to the Guardian’s Missing in the Amazon, the global environment editor Jon Watts goes in search of answers to the question Dom Phillips was investigating when he was murdered: how can we save the Amazon? In episode one of a three-part series, Watts explores what’s at stake if we fail to act in time. He hears about the crucial role of the rainforest for South America and the global climate, and looks back at how cattle ranching came to dominate and destroy huge swathes of the forest – pushing it to a dangerous tipping point today.
