“Pathways to a Sustainable Future- A Perspective from Pittsburgh” frames the struggle in the context of an ethical argument for preserving the living Earth. Examining the experience of a single city with all of its complexities allows a deeper understanding of the challenges and opportunities inherent in adapting to a changing world. Choices for more sustainable pathways for the future include transforming the energy system, restoring fertile ground, and preventing pollution through green chemistry production. Throughout the book, case studies responding to ethical challenges give specific examples of successful ways forward. Inspired by Rachel Carson’s voice of precaution in protecting the Earth, this is a book about empowerment and hope.
