Home 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 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.
