In Russia's remote Arctic regions reindeer herding has been a way of life for centuries. Each winter herders in Russia's sparsely populated Nenets Autonomous District corral their reindeers into open-air pens before selecting weak animals to be culled. The cull helps to preserve the region's fragile tundra by keeping herd sizes down, and local people sell reindeer meat, hide and antlers to make a living. Krasnoye is the only settlement in the Nenets region connected by road to the regional capital, Naryan-Mar, which is over 2,000 kilometres north of Moscow. Temperatures can sink below minus 40 degrees Celsius in winter. (Photo by Sergei Karpukhin/Reuters)
