Rare Earth

Helen Czerski and Tom Heap discover how new technology lets us listen in to the extraordinary sounds of the planet's waterways. From the deepest ocean to the tributaries, rivers and streams, this is an exploration of the sound made under water by animals, humans, and yes even plants. From the snapping of shrimp to the bark of a John Dory, Tom and Helen ask how sound travels through water, how important it is and what is known about the purpose of these sounds. They also ask what impact human activity is having on the watery soundscapes and their inhabitants. Joining Tom and Helen are Marine Biologist Steve Simpson, Former Submariner Bob Mansergh, Principle Scientist Rosalyn Seddon and Eco-Acoustician Jack Greenhalgh.

Is there any true wilderness left on our planet? Tom Heap and Helen Czerski consider the fear and fascination of the wild. They're joined by the writer Cal Flyn who has spent the last few years travelling the world in search of wilderness for her new book The Savage Landscape.

How can Britain- and the world- prepare itself for extreme heat? Tom Heap and Helen Czerski hear from the experts and from the people facing up to the hottest temperatures on the planet.

Amphibians are the most threatened type of vertebrates on the planet since the dinosaurs- and some of the most fascinating. Tom Heap and Helen Czerski are joined by a panel of amphibi-fans to celebrate the very best in frogs, toads, newts and salamanders. What can we do to reverse their rapid decline?
Jeanne Tarrant, founder of Anura Africa is an expert on the extraordinary diversity of frog life in South Africa, Jeff Streicher is Head of Zoology at National Museum Cardiff and James Herd is Director of Reserve Management at the Surrey Wildlife Trust.
Helen also takes a visit to London Zoo to meet our largest and smallest amphibians and discuss captive breeding programmes with Ben Tapley, ZSL's Curator of Amphibians and Reptiles. Finally we hear from two field ecologists working to save amphibians in the highlands of Cameroon and the tea gardens of Darjeeling. Marina Kameni and Barkha Subba are two of the winners at this year's Whitley Fund for Nature awards.
