Cossham on Carbon (and many other things)

To give you some pointers on how to control your carbon footprint I'm talking this time to John Cossham. And not just about being green and cutting carbon, but our wide-ranging discussions included population, changing the system, being vegan or vegetarian, the steady-state economy, doughnut economics, gross domestic happiness, tipping points and positive feedback, climate anxiety, near-term human extinction and why we should be doing good now – it's the right thing to do. And never, ever give up hope.
