“Earth bears the scars from 150 years of industrialization. Climate change compromises the life support system of all oxygen breathing, fresh water-dependent organisms, including humans.

The challenges manifest today present a daunting complex of causes and effects across all aspects of society, but an examination of the progress of a single important city may provide insight for a way forward.

Today Pittsburgh stands at an intersection between the historic fossil industry base and the potential for a renewable and sustainable future.

Pathways to a Sustainable Future shows how Pittsburgh is addressing the issues of climate change and global pollution. The solutions are not necessarily found in technology alone. Rather, the pathways forward are based on the ethical and moral basis for making choices about the future.

The first part of the book addresses the essential connection between people and the earth, its living systems, and how people can re-connect with the natural world.

The second part addresses some innovations to providing energy, food and materials. It explores the policies embedded in the current system and some of the new directions to achieve change.

The third part examines the social and cultural impediments to change and the means to address them.

This is a book of empowerment, inspired by Rachel Carson whose one voice rose in challenge to a system that presented danger to living systems and moved thousands to respond.

The situation facing humanity today calls for a unified response in defense of the Earth, for the sake of the children of the 21st century.

It is time to act. Examining the Pittsburgh story can give some insights to the problems and the possibilities for a sustainable future.”
