Most politicians and economists consider economic growth as the solution for all sorts of crises like unemployment, the debt crisis or global poverty. But since the Club of Rome report "The Limits to Growth", published in 1972, there are doubts whether the economy can go on growing without destroying its own foundations. Humankind is already consuming resources as if there were 1.5 planets available. Climate change and the destruction of biodiversity are accelerating. Tim Jackson, advisor to the British government and author of the book "Prosperity without Growth" explains why technology alone can't resolve the dilemma.
