As the sun rises over the Amazonian island of Marajo, Renato Cordeiro laces up his boots, grabs his knife, and heads out to tap his rubber trees. Drop by drop, he collects the milky white sap, known as latex, that sustains him. The recent revival of the rubber tapper trade in this impoverished northern Brazilian region has created jobs for families who once thrived during the Amazonian rubber boom, which collapsed in the late 20th century. A local company, Seringo, has enabled Renato and more than 1,500 rubber tappers to resume their craft. The company produces goods such as footwear while also protecting the forest, increasingly threatened by deforestation. IMAGES AND SOUNDBITES ARRANGED IN SEQUENCES
