Jodie Evans: We passed it. We've already been destroying the country -- the world the planet. Already in the last 20 years some of our tigers and lions are close to extinction. Large fish in the sea are 90 percent lost. Things that will never be replaced; the aquifers, the rivers, the oceans, the lakes the ground soil -- we have devastated much of the planet already so I think that line has already been crossed. There is an ecological limit to unsustainable economic growth. It’s the definition. And our growth has been unsustainable.
