Trees keep our planet cool and breathable. They make the rain and sustain biodiversity. They are essential for nature and for us. And yet, we are cutting and burning them at such a rate that many forests are fast approaching tipping points beyond which they will simply shrivel and die. But there is still time, and there is still hope. If we had a trillion more trees, the damage could be undone. So should we get planting? Not so fast. Fred Pearce argues in this inspiring new book that we can have our forests back, but mass planting should be a last resort. Instead, we should mostly stand back, make room and let nature — and those who dwell in the forests — do the rest.

Taking us from the barren sites of illegal logging and monocrop farming to the smouldering rainforests of the Amazon, Fred Pearce tells a revelatory new history of the relationship between humans and trees - and shows us how we can change it for the better. Here we meet the pilot who discovered flying rivers, the village elders who are farming amid the trees, and the scientists challenging received wisdom. And we visit some of the world's most wondrous treescapes, from the orchid-rich moutaintops of Ecuador to the gnarled and ancient glades of the South Downs.

Combining vivid travel writing with cutting edge science, A Trillion Trees is both an environmental call to arms and a celebration of our planet's vast arboreal riches.
