  • ENVIRONMENT DAY SPECIAL

DESCRIPTION

To sustain life on Earth, the planet has woven an intricate and delicate balance. How would humans and the planet cope if this balance was drastically and irrevocably altered? Take an unflinching look at exactly how precarious our existence may be. 

World Without Oil: Oil. It makes our modern world go round. We've used it to drive, fly and manufacture our way into the 21st century. But what would happen if the world that so depends on oil suddenly ran out? Visit a planet you will never see. An Earth without oil. How would we have to change our way of life – to live without the product we depend upon so heavily? 

In Population Overload, find out what would happen to the world if the population doubled overnight? How quickly would we run out of water? Power? Food? Mass migration would reshape countries. New high-rises would soar over the cities. But there are only so many resources to be shared among those who will be left behind, as the planet struggles to deal with twice the population. 

Imagine a time When The Earth Stops Spinning. We are no longer moving at 1000 miles per hour (1670 kilometres per hour) at the equator. Days and nights are six months long. Oceans part and flood northern and southern cities; most of those around the centre of the globe are airless and lifeless. A lucky few human nomads discover the "last place on Earth" where they can live year-round, a tiny ocean settlement where humanity ekes out the rest of its days on a non-spinning planet. 

Billions of years from now, the sun will expand into a Red Giant. As temperatures rise, the water will be boiled off the planet. See what happens as Earth dies under the fury of a rapidly aging star in Betrayed By The Sun.

EPISODE GUIDE

  • Environment Day Special: Dangerous Catch
    In the no-holds-barred frontier of the ocean, industrialised fishers and pirates grab what they can of the dwindling bounty of marine life. Surprisingly, the reduction of fish stocks is just the beginning of this strange story. Investigators suspect today's melee on the high seas may be setting in motion a series of startling global transformations. - In the West African nation of Ghana, olive baboons are ransacking crops and terrorising villagers. Further down the coast in Namibia, a once rich fishing ground is struggling to recover while putrid fumes are exploding from the ocean depths. Both these events are linked to one activity: over-fishing.
  • Environment Day Special: Dirty Secrets
    In our relentless drive to meet the needs of more than six billion people - nine billion by the end of the century - we're producing, and struggling to manage, a mind-boggling volume of waste. Investigators believe that job - and the stakes involved - may be bigger than previously imagined. They are seeing gruesome signs that the casually discarded by-products of modern life are altering the global water system that unites streams, rivers and the sea, profoundly influencing life on Earth. Scientists and citizens across the world are scrambling to solve a set of disturbing mysteries unfolding along the shores of rivers, estuaries, islands and the sea. Striped bass are succumbing to flesh-eating bacteria in Chesapeake Bay. - Meanwhile, a known hormone-disrupting chemical is showing up in streams, rivers and other bodies of water across the nation, potentially jeopardising the health of animals and humans.
