"On land and in the seas, green plants make the oxygen and food that many living things--including us--need to survive. Covering the evolution of the first plants billions of years ago, the secret, microscopic workings of trees and leaves today, and the role of plants in both creating fossil fuels and combating climate change, this book is a lush and fascinating introduction to the science of plants that goes well beyond photosynthesis. Nicola Davies and Emily Sutton,have crafted a hopeful exploration of green life that will encourage readers to treasure the flora of Earth's many ecosystems."-- Publisher's website
