CREATION OF A THOUSAND FORESTS IN ONE ACORN T-Shirt

Some answers are simpler than others and this may be one of them. Emerson states it clearly and precisely: "The creation of a thousand forests is in one acorn." It's true. It's the cycle of the seasons, the tiny acorns fall from the trees, planting themselves where they fall, the ground and the sun and the rain nurture them, and from them come trees, trees and more trees. And those trees are our friends. Just one service they do for us is cleanse our air. We need to keep these friends close!
