High in the rugged mountains of Nepal, communities in the valley of Nubri are confronting rapid changes. In recent years, the majority of school-age children from Nubri leave their villages to be educated in boarding schools or monasteries outside the valley. What opportunities do these children have once they finish school, and what happens to these ethnically Tibetan communities if the children never come home? Anthropologist Geoff Childs, who has been working in Nubri for decades, explains a complicated story of outmigration and cultural change.

Yet in places like Bolivia, where many citizens still use firewood as their main energy source, the conversation can sound much different. There, the desire for convenience and progress often overrides environmental concerns, and in some cases, also the rights and safety of indigenous people. Anthropologist Bret Gustafson is working on a book about gas and power in Bolivia. Here, he discusses the complicated relationship between energy, politics, the environment, and indigenous rights.
