Book excerpt: Permaculture is a sustainability buzzword, but many people wonder what it actually means and why it is relevant. Originally coined by combining the words permanent and agriculture, permaculture has evolved into an optimistic approach connecting all the systems of human life: gardening, housing, transportation, energy, and how we structure our communities. The Permaculture Promise explains in simple terms why permaculture may be the key to unlocking a livable future on our planet. Author Jono Neiger asserts that humans can thrive while simultaneously making Earth healthier and not destroying it. The book shows 22 ways that permaculture can create a better future for all living things. Profiles of people and communities — including an urban dweller who tore up her driveway to create a vegetable garden and a California housing development that dedicates a third of its land to parks, orchards, and gardens — will inspire you to incorporate permaculture principles into your life today.
