We all love trees. We all know their essential role in nature and that the planet's forests are the natural reserve that protects life. But do we really know them? Do we know how they evolved, how they reproduce, why some trees are so enormous, what types of leaves exist, and what roots are usually like? This new title in the "Secret Life" collection will introduce you to a special, magical, and interesting world from every point of view. Trees have a secret life that you may not be aware of. They relate to the environment in which they grow and to other trees. They suffer from pollution. They feed and sometimes go hungry. Some are even dominant, others shy; some are selfish, and others very sociable.
