This is an extraordinary book about trees. It's an account by a veteran science journalist that ranges to the limits of scientific understanding: how trees produce aerosols for protection and 'warnings'; the curative effects of 'forest bathing' in Japan; or the impact of trees in fertilizing ocean plankton. There is even science to show that trees are connected to the stars. Trees and forests are far more than just plants: they have myriad functions that help maintain the atmosphere and biosphere. As climate change increases, they will become even more critical to buffer the effects of warmer temperatures, clean our water and air and provide food. If they remain standing. The global forest is also in crisis, and when the oldest trees in the world suddenly start dying - across North America, Europe, the Amazon - it's time to pay attention. At the heart of this remarkable exploration of the power of trees is the amazing story of one man, a shade tree farmer named David Milarch, and his quest to clone the oldest and largest trees - from the California redwoods to the oaks of Ireland - to protect the ancient genetics and use them to reforest the planet.
