Homo Ecophagus by Warren M. Hern is a wide-ranging look at the major problems for the survival of not just the human species, but all other species on Earth due to human activities over the past tens of thousands of years. The title of the book indicates Hern’s new name for the human species: “The man who devours the ecosystem.” Over the course of its evolution, Hern observes, humans have evolved cultures and adaptations that have now become malignant and that the human species, at the global level, has all the major characteristics of a malignant neoplasm ・ converting all plant, animal, organic, and inorganic material into human biomass or its adaptive adjuncts and support systems. Hern contends that this process is incompatible with continued survival of the human species and most other species on the planet, offering a diagnosis and prognosis of the current environmental impasse.

A visionary ecopsychologist examines the rift between human beings and nature and shows what can be done to bring harmony to both the ecosystem and our own minds. • Shows that the solution to our ecological dilemma lies in our own consciousnesses. It is becoming more and more apparent that the causes and cures for the current ecological crisis are to be found in the hearts and minds of human beings. For millennia we existed within a religious and psychological framework that honored the Earth as a partner and worked to maintain a balance with nature. But somehow a root pathology took hold in Western civilization--the idea of domination over nature--and this led to an alienation of the human spirit that has allowed an unprecedented destruction of the very systems which support that spirit. In Green Psychology Ralph Metzner explores the history of this global pathology and examines the ways that we can restore a healing relationship with nature. His search for role models takes him from shamanic ceremonies with the Lacandon Maya of Mexico to vision quests in the California desert, from the astonishing nature mysticism of Hildegard von Bingen to the Black Goddesses and Green Gods of our pagan ancestors. He examines the historical roots of the split between humans and nature, showing how first sky-god worshiping cultures, then monotheisms, and finally mechanistic science continued to isolate the human psyche from the life-giving Earth. His final chapters present a solution, showing that disciplines such as deep ecology and ecofeminism are creating a worldview in which the mind of humanity and the health of the Earth are harmoniously intertwined.

We live in times of uncertainty and insecurity, at a personal, national and global level. Writers such as Samuel P. Huntington and Robert D. Kaplan, respectively, have spoken of an emerging 'clash of civilizations' and of 'coming anarchy'. This book is also concerned with the future of civilization, in particular with the conflict between economic growth and the sustainability of the biophysical lifesupport systems of the planet, arguing that the flawed system of orthodox neo-classical economics has justified the modernist belief in the necessity of unending economic growth and the ceaseless exploitation of nature.

This scientifically rigorous and philosophically sophisticated defense of environmentalism is meant to excite, educate, and alarm the reader. There is a widespread scientific and public recognition that the world is facing an environmental crisis of vast proportions. What is the relationship between the growth of human population and industrial activity on one hand and the environmental crisis on the other? If this is not determined and dealt with, Earth's ecology may be expected to collapse.

Originally published in 1972, Homo Sapiens examines how humans emerged from among the millions of other species and achieved our unique position within the animal kingdom. The book examines what direction future evolution will take and what may be regarded as the ‘meaning’ of human existence. It stipulates that these are the questions for which no real basis of discussion existed before the 20th century, and at the time of publication, some were still without a definite answer. The book sets out analyse these questions and the continuing debate that has arisen from their study. This is an account of the uniqueness of man in the animal kingdom, how this uniqueness arose during evolution, and what traces of it can be detected in animals other than man. The book describes the mental and physical evolution of man, from his earliest ancestors to the present day. He also gives an account of man’s cultural development seeking to establish that there is an underlying principal of cultural evolution, a principle that has been denied by many historians. Later chapters deal with the future and with possible forecasts of mankind’s further physical, intellectual and cultural evolution.

Converging evidence from disciplines including sociobiology, evolutionary psychology and human biology forces us to adopt a new idea of what it means to be a human. As cherished concepts such as free will, naïve realism, humans as creation's crowning glory fall and our moral roots in ape group dynamics become clearer, we have to take leave of many concepts that have been central to defining our humanness. What emerges is a new human, the homo novus, a human being without illusions. Leading authors from many different fields explore these issues by addressing a range of illusions and providing evidence for the need, despite considerable reluctance, to relinquish some of our most cherished ideas about ourselves.
