Leaders of indigenous peoples of the Brazilian Amazon participating in the World Social Forum on Biodiversity held in Manaus, Brazil in January 2015, repudiated countless actions by the Brazilian state that violate the national constitution and international law. Construction of large hydroelectric plants in the Amazon region without consulting affected communities, a clear bias towards agribusiness, strong pressure from mining companies seeking approval of a bill that would open up indigenous lands to exploitation and the militarization of the Amazon are some of the threats to the environment and indigenous peoples’ life and culture, including native groups that have no contact with the society around them.
