HUNGER AND MALNUTRITION â USE BOTTLE TOWERS
Building towers of recycled bottles and/or pots offers fantastic opportunities to grow fresh food with a minimum of water and fertilizer. One can grow at home, in cities and villages, all kinds of vegetables and herbs. Bottle towers are a wonderful tool to alleviate hunger and malnutrition. They can be build at the lowest cost by any family everywhere on earth, particularly in drylands and deserts.
