We’re resourceful, adaptable and the smartest thing this planet has ever seen. We got ourselves into this mess but we can get ourselves out of it.
BBC Radio Four, in partnership with the Royal Geographical Society, presents 39 ideas to relieve the stress that climate change is exerting on the planet.

From tiny rice seeds and perovskite solar cells to the total transformation of landscapes, Tom Heap and Dr Tamsin Edwards view the fundamental problem of our age from a fresh perspective. Small things that make a big difference. Big things that make a small difference. We’re going to need every one of them.

In the fourth batch of fascinating ideas they meet the robot that makes ships slippier, find fresh ways to stop cattle belching methane and investigate logging techniques that can help save precious tropical forests.
