A world expert on how trees chemically affect our environment, Diana Beresford-Kroeger has woven together ecology, ancient myth, horticulture, spirituality, science and alternative medicine in The Global Forest to capture their enormous significance to us - and our future. From enormous native Savannah trees that create their own sunscreen to hedgerows that contain and entire chain of life, this book shows us the power of the global forest. Trees absorb pollutants from the ground, comb particulates from the air and house beneficial insects. But what they do chemically in the environment is something we're only beginning to understand. Trees not only breathe and communicate; they also reproduce, heal and even nurture, and each of these forty interlocking essays picks out a different aspect of the life of the forest, explains it and then shows why it is so vitally important. Combining the precision of a scientist with the lyricism of a poet, Diana Beresford-Kroeger has written an unforgettable work of natural history that shows how we really can save the Earth, one tree at a time.
