Austrian naturalist Viktor Schauberger (1885-1958) was far ahead of his time. From his unusually detailed observations of the natural world, he pioneered a completely new understanding of how nature works. He also foresaw, and tried to warn against, the global waste and ecological destruction of our age. This book describes and explains Schauberger's insights in contemporary, accessible language. His remarkable discoveries -- which address issues such as sick water, ailing forests, climate change and, above all, renewable energy -- have dramatic implications for how we should work with nature and its resources.
