At a time when the Earth's surface is changing faster than ever in human history, watch cities grow, forest disappear and glaciers melt. In the ever-growing grey of cities one man is feeding thousands of parakeets; in Sumatra a female orangutan and her daughter face life in a forest under threat; while in Tanzania local people use satellites to replant a forest, securing the future for a family of chimpanzees. This is our home as we've never seen it before.

All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky, a cliff carved by a waterfall twice the height of Niagara, and potholes large enough to swallow cars. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the world’s top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland and, improbably, on the seabed of the English Channel. There, another deluge smashed through a land bridge connecting Britain and France hundreds of thousands of years ago and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hours—and similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.

Few places on Earth remain largely untouched and uninhabited by humans, but such spots exist in the middle of the Atlantic Ocean. Welcome to the Mid-Atlantic Ridge, a vast chain of volcanic mountains that have surfaced as tiny, isolated islands thousands of miles from any mainland. These worlds serve as both playgrounds and sanctuaries, where some species struggle and others thrive. Discover the secrets of these little-known oases as we explore eight islands, from the Arctic to the Antarctic.
