Joking that he felt like an old-time hell-fire preacher speaking from the pulpit of Hope Baptist Church, George Monbiot instead brought a vision of hope to the packed audience yesterday at Hebden Bridge Arts Festival.

Launching a national rewilding group – [ now launched, one year on] – he extolled the delights of an environment where biodiverse plants, insects and animals flourish thanks to the reintroduction of keystone species at the top of the food chain – such as beavers, pine martins and wolves.
