Nitrogen pollution of lakes, rivers and oceans by human urine is a growing problem. Liquid Gold shows how urine can safely be used to grow food, fuel, fiber and beautiful landscapes while protecting the environment and providing free and safe fertilizer. Featuring a short history of urine use—from ritual to medicinal and even culinary—and many whimsical illustrations, this great bathroom reader is an ideal gift for irreverent gardeners, homeowners, campers, environmentalists and anyone who urinates.
