Before the world was outraged by the murders of British journalist Dom Phillips and Indigenous advocate Bruno Pereira, it was aghast at the killings of Chico Mendes and Dorothy Stang.
Mendes was a rubber tapper and unionist murdered by ranchers in 1988 in the southern Amazon; 73-year-old Stang was a US nun assassinated in 2005 for standing up to illegal loggers on the other side of the rainforest.
