We speak with Indigenous lawyer Eliésio Marubo in Brasília, about calls to independently investigate the murders of British journalist Dom Phillips and Indigenous advocate Bruno Pereira. When they went missing in Brazil’s Amazon rainforest, he helped to coordinate a search-and-rescue mission. He went to Washington, D.C., to coordinate support for the investigation and to raise awareness for the safety of the Indigenous communities, and coordinated a public letter signed by 23 congressmembers that read in part: “This human-level tragedy is a symptom of a broader assault on the Amazon rainforest, which is pushing the vast ecosystem to an ecological tipping point.”
