The vast tar sands surface mines of Alberta are among the most destructive industrial projects in human history, having already transformed more than 160 square miles of wetlands and forest into a post-apocalyptic moonscape. Because few Americans will ever see this scorched-earth degradation firsthand, we decided to show you some photos, taken by Canadian photographer Garth Lenz."
