Acre is a state in the northwest of Brazil, nestled in the heart of the Amazon rainforest, bordering Peru to the west and Bolivia to the south. Known as the greenest state in Brazil, over 50% of its territory is protected, preserving vast tracts of lush, tropical forest teeming with biodiversity. The capital, Rio Branco, is a cultural hub with architecture reflecting both forest and indigenous influences. Historically, Acre was a significant center for rubber extraction, drawing many immigrants during the rubber boom, and it played a key role in the Acre War, which led to its incorporation into Brazil in 1903. Today, the state's economy revolves around agriculture, cattle ranching, and rubber production, with a strong emphasis on sustainable practices and environmental conservation, highlighted by figures like Chico Mendes, an advocate for the sustainable use of the Amazon's resources.
