Steinfeld, Carol
Every day, we urinate nutrients that can fertilize plants - plants to could be used for beautiful landscapes, food, fuel, and fiber. Instead, these nutrients are flushed away and treated at high cost. Or they are discharged to waters where they overfertilize and choke off aquatic life. Urine accounts for most of the nutrients in domestic wastewater, and it usually carries no disease risk. Liquid Gold: The Lore and Logic of Using Urine to Grow Plants tells you how to put it to work as a resource. Starting with a short history of urine use (from ritual to medicinal to even culinary) and a look at some unexpected urinals, Liquid Gold shows how urine is used worldwide to grow food and landscapes, while protecting the environment, saving its users the cost of fertilizer, and reconnecting people to the land and the nutrient cycles that sustain the. That's real flower power!
