Building treehouses at the edge of the forest, catching crabs in the stream, or having a picnic in the flower meadow? Many children have lost their desire to be outdoors: it's too dangerous, too dirty, too loud. Instead, they immerse themselves in virtual worlds, huddling behind gaming consoles or only knowing nature from museums. However, without contact with the forest, meadow, and stream, without space to climb, collect, and play in the mud, imagination, physical awareness, and emotionality wither away. How can parents and educators address the growing alienation from nature? How can children be inspired to play outside again? And where can wilderness be experienced? Gerhard Trommer passionately advocates for a rediscovery of the wilderness and for more open spaces. His book is filled with thought-provoking ideas and tips for a fulfilling life for both children and adults.
