In December 1988 the Brazilian environmental campaigner, Chico Mendes, was shot dead by cattle ranchers, unhappy at being prevented from exploiting land in the Amazon jungle. The 44-year-old leader of the rubber tappers union had become a powerful symbol of the struggle to save the Amazon and his death sparked renewed interest in environmental issues world-wide. Mike Lanchin has been hearing from the anthropologist Mary Allegretti, who was a close friend of Mendes and worked alongside him in the jungle. Photo: Chico Mendes and his family.
