The lawless destruction of the Amazon rainforest is an emergency that touches us all: A unique resource seen as vital to averting catastrophic global warming is being decimated. Under Brazilian President Jair Bolsonaro, deforestation is at a 15-year high. The forest is racing toward what scientists warn is a tipping point, when it can no longer maintain its base ecology and suffers a spreading dieback. In this series, The Washington Post travels to some of the Amazon’s most remote and dangerous regions to reveal how crime, corruption and greed are leading to its systematic dismantling — and how Brazil, and the world, are failing to ensure the integrity of the planet’s largest rainforest.
