"Short of Aphrodite, there is nothing lovelier on this planet than a flower, nor more essential than a plant. The true matrix of human life is the greensward covering mother earth. Without green plants, we would neither breathe nor eat. On the undersurface of every leaf, a million movable lips are engaged in devouring carbon dioxide and expelling oxygen. Altogether, 25 million square miles of leaf surface are daily engaged in this miracle of photosynthesis, producing oxygen and food for man and beast." Peter Tompkins and Christopher Bird - The Secret Life of Plants
