Rare Earth

Cornish fishermen this summer have had their usual catch of lobster and crab replaced by voracious octopus. Restaurant menus have had to be wiped and rewritten across the south-west, but what else has changed? Tom Heap and Helen Czerski ask why octopus have such a hold on our imagination and the science world, why the octopus has moved north and what its journey can tell us about the changing oceans.
Joining Tom and Helen are the writer Sy Montgomery, marine biologist Dr Keith Hiscock MBE and octopus neuroscientist Dr Amy Courtney of the Marine Biological Association.

Helen Czerski and Tom Heap ask if nature is really red in tooth and claw. Is life all about survival of the fittest or are we all working together on a changing planet?
They're joined by Rowan Hooper, author of Togetherness, lichen expert April Windle and Isabel Hardman, assistant editor of the Spectator magazine and author of The Natural Health Service: How Nature Can Mend Your Mind.
Together they discuss the plants and insects that rely on deals with other species to keep themselves healthy, from fungus-farming ants to the Wood Wide Web that connects most living plants. April shows Helen the wondrous lichens of Hyde Park and Rowan discovers the orchids studied by Charles Darwin at his home in Kent.

Who's the hero that will protect us from the impact of extreme heat, rain and whatever else climate change might throw at us in future? Forget someone in a cape, maybe it's the person quietly sketching buildings on a bit of paper.
Architects shape the buildings we live in and rely on - can they change the way they work to make sure that our homes are smart enough to outpace the challenges of climate change? And can they lead the way in cleaning up the impact of the building industry? Or is the challenge just too great?
We find out with the help of:
- Isabel Allen, editor of Architecture Today
- Barnabas Calder, reader in architecture at the University of Liverpool
- Jay Morton, director of Bell Phillips Architects and incoming President Elect of RIBA
With thanks to Jess Hrivnak, and Melissa Mean and Jasmine Tippett from WeCanMake.
