To fish, the natives of Yomibato will take the roots of the Barbasco plant, which are toxic enough to stun fish. They mash the root into pulp, release it into the water and wait for the fish to float. Gloria, 26, is pictured using this technique. As she searched for the floating fish, she waded the stream while humming to her favorite tune while carrying her machete. Gloria lives in Yomibato, the most remote and farthest native community in Manú National Park.
