publication · 2026-04-27

In 2022, Paul Smith, the director of Botanic Gardens Conservation International, released 'Alberi. I polmoni verdi della Terra' (Trees: The Green Lungs of the Earth) through Rizzoli in Milan. This 320-page work encompasses topics such as seeds, leaves, bark, and symbiosis, culminating in a chapter that explores humanity's reliance on forests. It traces the origins of the first forests dating back 400 million years and reveals that there are around 3,000 billion trees currently. Notable features include the tallest tree, a California sequoia measuring 115 meters, the oldest tree, a pine over 3,000 years old, and the widest tree, a banyan located in India. Smith also weaves in art, literature, and the concept of shinrin-yoku (forest bathing), highlighting the significance of trees in the face of climate issues. The book concludes with a bibliography and glossary.
