They are all around us, so familiar that we barely notice they are there, moving so slowly that it’s easy to forget they are living. Plants are little more than wallpaper, the background to our lives. We use them, for fuel, building materials, food, medicine — not to mention air, but we take them for granted. Humans couldn’t live without plants. Plants have been looking after planet Earth for 500 million years, improving it for all other life — we should trust in them, and believe in flower power!
