Children play with bubbles during events celebrating the 12th anniversary of the village of Kuetuvy in the Canindeyu department of Paraguay, on Jan. 20. The Ache are hunter-gatherers whose population of roughly 1,200 is distributed in five villages in eastern Paraguay. They also celebrated the recent success of their exports to the United States of shade-grown, organic yerba mate, a drink brewed from the leaves of the rainforest holly tree. In 2010, Paraguay’s Congress gave them formal title to the land.
