Can I call you back to...

OK..to be clear, when you say..

"I mean a system that is closed" I ask..What is this "system"?

"Effectively, I mean at a global level"... Can you help me understand what you mean by a global system?

"We cannot currently grow away from this planet".....eh?

"The amount of energy available to us is limited to what the sun provides"... I have to ask, and what about wind, wave, nuclear, carbon-based etc etc?
