Planet Earth Extremes

Take an adrenalin-fueled journey to the most remote locations on Earth to discover how animals survive and adapt to extreme conditions. From the peaks of Mt. Everest to the bottom of the deepest sea, where bizarre forms of life thrive in a lightless world. From the icy poles to the world's greatest deserts, where animals endure the planet's most inhospitable and remote locations. A repackaged version of "Planet Earth" with Mike Rowe narrating "Planet Earth Extremes" instead of Sigourney Weaver (in the US version of "Planet Earth" ) and David Attenborough (in the UK version of "Planet Earth" ).
