The Cold and the Dark is the record of the Conference on the Long-Term Worldwide Biological Consequences of Nuclear War, held in Washington, D.C., on October 31 to November 1, 1983. The conference involved over 200 scientists from many nations and drew together the best available scientific information. Its central finding was the phenomenon of nuclear winter: a much more profound and long-lasting devastation of the earth and atmosphere than had been believed possible before. In the two principal papers, Carl Sagan presents the atmospheric and climatic consequences of nuclear war and Paul Ehrlich summarizes its biological implications. Also included is the text of the "Moscow Link" --a dialogue between Soviet and American scientists on nuclear winter--and the technical papers providing the scientific evidence for the book's conclusions.

Co-publication with Yale University Press (USA). Discussion of the biological diversity of the earth. Demonstrates how the natural systems that surround us play an essential role in protecting our basic life-support systems. Describes the millions of species providing ecosystem services and explains how biological diversity opens the way for new medicines, construction materials and designs, and manufactured goods. Urges us to protect the biological wealth of the earth from destructive human activity. Includes reccommended reading and index.

When we think of family, we most often think of our sisters and brothers, our cousins and grandparents, rather than our world family or even our community connections. We still identify with our differences more than our similarities, unless it's convenient to do otherwise. Here, two seasoned authors tackle the question of family and what it means to us now and how it might change to help us address the problems that affect us all. Using specific examples throughout the work, they present a unique approach to what it means to belong to one human family. Beginning with a consideration of how the family unit has begun to be defined by allegiances, by common ties and empathy, the authors then discuss the evolution of the family unit and how the "us" vs. "them" mentality gave way to a way of life that separated peoples rather than brought them together. They consider family values, how they arose, developed, were perverted or perfected to suit the family unit's needs, and the confusion that followed. Humanity on a Tightrope focuses on what families and family values are, and how they often create an "us versus them" mentality that is at the root of many of today's most crucial problems from terrorism, racism, and war to the failure of humanity to come to grips with potentially lethal global environmental problems. The book underlines a basic element for solving the human predicament - quickly spreading the domain of empathy. It takes a close look at how we can do that, building on the findings of both social and natural science and using tools ranging from brain imaging to the internet. It explains how civilization is unlikely to persist unless many more people learn to put themselves in the shoes of others to keep society balancing on the tightrope to sustainability - a tightrope suspended over the collapse of civilization.

Recipient of the ECI Prize in 1993 for terrestrial ecology. Reviews and analyses the essential aspects of modern ecological research and its bearing on society and on related sciences. The author deplores that many ecologists are not doing enough to motivate society into counteracting the increasing degradation of our environment. Hence, he outlines and discusses what, in his opinion, research ecologists should do to avoid the world's plunge towards ecocatastrophe.
