Book excerpt: Tested skills for thriving in the age of limits Merlin, Gandalf, Voldemort-these well-known sorcerers from popular culture are famed for their amazing spells and spectacular magical powers. In ancient times however, a wizard was actually a freelance intellectual whose main stock in trade was good advice, supported by a thorough education in agriculture, navigation, political and military science, languages, commerce, mathematics, medicine, and the natural sciences-in essence, the true Renaissance man. Greer proposes a modern mage for uncertain times; one who possesses a startling array of practical skills gleaned from the appropriate tech and organic gardening movements forged in the energy crisis of the 1970s. From the basic concepts of ecology to a plethora of practical techniques such as composting, green manure, low-tech food preservation and storage, small-scale chicken and rabbit raising, solar water heating, alternative energy sources, and more; Green Wizardry is a comprehensive manual for today's wizard-in-training. Providing a solid practical introduction to the entire appropriate tech toolkit, this book is a must-read for anyone concerned about decreasing our dependence on an overloaded industrial system and, in a world of serious energy shortages and economic troubles, making life a great deal less traumatic and more livable.
