The founder of the international Transition Towns movement asks why true creative, positive thinking is in decline, asserts that it's more important now than ever, and suggests ways our communities can revive and reclaim it. In these times of deep division and deeper despair, if there is a consensus about anything in the world, it is that the future is going to be awful. There is an epidemic of loneliness, an epidemic of anxiety, a mental health crisis of vast proportions, especially among young people. There's a rise in extremist movements and governments. Catastrophic climate change. Biodiversity loss. Food insecurity. The fracturing of ecosystems and communities beyond, it seems, repair. The future - to say nothing of the present - looks grim.
