Our investigation reveals how heavy machinery in the Russian Arctic harms ecosystems, the climate, and Indigenous communities. In the Russian Arctic, the heavy tracked all-terrain vehicle—hauling cargo across snowy wastelands and summer swamps—has become a symbol of human conquest over the tundra. In eight Arctic regions of Russia, the investigative project Arctida has documented dozens of large-scale cases where tundra vegetation has been destroyed by the movement of heavy transport.
