PRINCE CHARLES OF BRITAIN:

"If the planet were a patient, we would have treated her long ago. You, ladies and gentlemen, have the power to put her on life support, and you must surely start the emergency procedures without further procrastination."

"Humanity faces many threats but none is greater than climate change." he said. "In damaging our climate we are becoming the architects of our own destruction. We have the knowledge, the tools and the money (to solve the crisis)."
