Costing the Earth

Britain is running out of power. Ten new nuclear reactors were supposed to provide the solution. In this week's 'Costing the Earth' Tom Heap asks if the events in Japan have dealt a fatal blow to the future of the industry.

Tom will be examining the changes in safety regimes that may be provoked by the ongoing disaster. He'll also be asking if the economic case for nuclear has changed and looking ahead to the future supply of uranium.

Will power and prosperity shift to the frozen North? A new book predicts that Iceland, Greenland, Denmark, Sweden, Finland, and Russia will be the beneficiaries of a new world order.

By 2050, four megatrends - climate change, rising population, globalisation and resource depletion - will lead to the rise of 'The New North', as migration, energy bonanzas and international trade will turn the world upside down. Geographer Professor Laurence Smith tells Laurie Taylor why these projections amount to more than planetary palm reading.

Time to Remember

The endeavour, innovation and technological breakthroughs of the first half of the 20th Century are illustrated through newsreel footage and the 1950s narration of the original Time to Remember documentary series.

This programme includes footage of tanks on the battlefields of the Great War, Scott's expedition to Antarctica, Mallory and Irving on Everest, Roosevelt at the Boulder Dam and a car testing its very necessary roll-bar.

The Truth About Lions

Lions are strangely social, the only wild cats to live in family groups. Lion expert and BBC Big Cat Diary presenter Jonathan Scott investigates the reason why with the help of the most famous lion pride in the world - the Marsh Pride of the Masai Mara in East Africa.

Jonathan's intimate knowledge of this massive pride and their various sub-groups helps him explore the possible reasons for the lion's social lifestyle. While there are some apparent benefits to living in prides, none appear to be a reason enough to evolve social living. Now after 30 years of study, the Serengeti Lion Project may have finally found the answer.
