Under the Sea

From the icy poles to the deepest parts of the oceans, humans have explored Earth’s most challenging environments, and have even journeyed on into space. But how did these places form and what are the features that make them unique? How do humans live and work in these harsh landscapes? Most importantly, how is human activity impacting them and their natural inhabitants and wildlife, and what does the future hold for them?
Amazingly, more than 80 per cent of Earth’s five great oceans remain unexplored today. Life at Extremes: Under the Sea journeys into the mysterious world beneath the waves to discover its unique features and wildlife, and explores how we can live and work deep below the sea.
