Without care, reforestation projects can damage ecosystems and be useless as carbon stores. Here's how to go about it the right way.
Much of the UK's farmland is unproductive. It could be put to better use storing carbon, offering recreation and providing wildlife habitat.
Restoring Britain's woodlands and peatlands isn't just a utopian dream.
If nothing is done now, seas could rise a metre by 2100, and four metres by 2300.
At best, planting trees won't be enough on its own to slow climate change. At worst, it's a dangerous distraction.
'Natural climate solutions' are vital. But huge plantations of the same tree should not count.
