In arctic northern Russia, industrialized resource extraction and climate change are presenting a double threat to the Nenets, an indigenous people native to Siberia. The Nenets depend heavily on their reindeer herds, using them for food, clothing, tools, transportation, and more as they migrate more than a thousand kilometers across the tundra every year. Photographer Steve Morgan recently traveled to the Yamal Peninsula to document the Nenets and their threatened way of life. Here is a selection of his photos, with captions by Joanna Eede of Survival International.
