In 2001, at age 26, Tashka became responsible for 600 people and 90,000 hectares of Amazon rainforest in Brazil as Chief of the Yawanawa. Tashka has since managed to double the Yawanawa territory, reinvigorate Yawanawa culture, and establish economically and socially empowering business partnerships with the outside world. These innovative ventures prove that maintaining cultural integrity, and protecting the rainforest need not conflict with achieving economic prosperity. His work in sustaining the Yawanawa culture, wisdom, plant knowledge, cosmology and language is an immeasurable contribution to the legacy of humanity.
