A famous native American proverb says 'Only when the last tree has died, and the last river been poisoned, and the last fish been caught, will we realise we cannot eat money.' The panel's three leaders challenge this pessimistic prediction by discussing values - financial and what we love and care about - that we place on our land, food and water. They will range across themes including seed democracy, urbanisation and land management and what this means for the health of the planet and ourselves.
