We got ourselves into this. Here's how we can get ourselves out.

We know the problem: the amount of biodiversity loss, the scale of waste and pollution, the amount of greenhouse gas we pump into the air... it's unsustainable. We have to do something.

And we are resourceful, adaptable and smart. We have already devised many ways to reduce climate change - some now proven, others encouraging and craving uptake. Each one is a solution to get behind.

In 39 Ways to Save the Planet, Tom Heap reveals some of the real-world solutions to climate change that are happening around the world, right now. From tiny rice seeds and fossil fuel free steel to grazing elk and carbon-capturing seagrass meadows, each chapter reveals the energy and optimism in those tackling the fundamental problem of our age.

Accompanying a major BBC Radio 4 series in collaboration with the Royal Geographical Society, 39 Ways to Save the Planet is a fascinating exploration of our attempt to build a better future, one solution at a time. A roadmap to global action on climate change, it will encourage you to add your own solutions to the list.
