A Quotation from Cradle to Cradle
Imagine the primordial beginning of life on this planet. There is rock and water - matter. The orb of the sun sends out heat and light - energy. Eventually, over thousands of milleninia, through chemical and physical processes scientists still don’t fully understand, single-celled bacteria emerge. With the evolution of photosynthesizing blue-green algae, a monumental change takes place. Chemistry and physics combine with the sun’s physical energy, and the Earth’s chemical mass turns into the blue-green planet we know.” - William McDonough & Michael Braungart, Cradle to Cradle: Remaking the Way We Make Things
This is a brilliant book, and of course, now I’m partial to the above quote for obvious reasons.
