My sketch/idea highlights the fact that nature is economical, it wastes nothing as acknowledged by the author Kabelo Sello Duiker (The Quiet Violence Of Dreams) Nature has a way of equilibrating itself. The human hand can both nurture and destroy nature. Global warming is the aftermath of human greed, complacency and a don't care attitude. We cut down earth lungs for our voracious appetite for beef, beautiful furniture, big houses or worse Coca plantations. We know carbon dioxide is bad, we generate methane gas through our waste which we can recycle into green energy. But we worry about monetary costs and politics. The next world war would be sparked by a dwindling water supply.
