Sustainability describes the innovations that will likely play a role in the near future for creating a critical mass in the environment's favor. Opening with a chapter describing the ecosystem of humans, animals, plants, and other life, this new full-color guide provides an overview of ecology and the philosophy of living for the environment rather than taking from it. It goes on to explore some places in the world that have started making changes in order to live in a sustainable way as well as some new materials that conserve natural resources.
