A brief exercise in memory would enumerate a profusion of extraction materials and their presence in modern South American literature. Iron, gold, silver, coffee, mate, tobacco, sugar, cocoa, rubber, horses, cattle, and more. Labor relations in the production and/or extraction of these materials, as well as the prior relationships of interspecies coexistence between indigenous groups and the beings with whom they shared the territory, are also privileged themes in many works that have attained canonical status.
