Lost rivers
What happens to once-thriving freshwater ecosystems when the rivers they depend on are entombed in sewer pipes beneath layers of concrete and soil? National Geographic explores some of the world's lost rivers including London's Fleet and Westbourne and Moscow's Neglinnaya.
As this photo shows, some of these buried rivers are now fascinating architectural wonders in their own right: manmade cave systems with graceful brickwork vaulting and columns in place of stalagmites. No doubt also rats the size of cats, and ghostly, troglodytic denizens. But Nat Geo doesn't go there!
