In order to provide meaningful information for evaluating environmental consequences of alternative control strategies of air pollutant emissions, scientists have recently initiated numerous studies aiming at collecting and making use of regional data. New kinds of mathematical models have been developed that no longer are calibrated just for individual stands or catchments but can be applied on a large regional scale. Such regional models and data were reviewed at a meeting" Models to describe the geographic extent and time evolution of acidification and air pollution damage", organized by the Finnjsh Research Project on Acidification (HAPRO), and held in Aulanko, Hiimeenlinna, Finland, July 5-8, 1988. This volume is based on the outcome of that meeting. The chapters of the volume are written by leading scientists in the field. The main objective of this volume is to discuss the potential of regional models to analyze the geographic extent of acidification as well as the environmental damage and the time evolution of:the responses of the environment. First, in Part I of the volume, sensitivity distributions of ecosystems, forest soils and surface waters are described. The focus of interest is therefore extended from the most sensitive ecosystems to sensitive and moderately sensitive parts of the environment. When formulating national and interna tional targets, it is of crucial importance to know the whole distribution of critical loads within the area, and not only the level the most sensitive ecosystem can tolerate.

How is it that billions of human beings continue to believe that there are mysterious deities hovering over us concerned with what we say, what we eat, and how we behave, and apparently with the ability to create the entire universe from its beginning, but can't seem to find a cure for the common cold; never mind disease, disaster, and destruction on a global scale? Author Richard F. Wright offers the answer in the form of his analysis of the prophets who created lies of such enormous proportions that humankind can't seem to unravel itself from the myths, mysteries, and mindlessness. Wright wrote the book initially as a letter to his wife Patti, acknowledging that she had figured out for herself, quickly and accurately, that there are no such things as deities and that organized religion ruins everything. After an extended review of the literature on the topic, Wright confirmed for himself, what his wife already knew, that his feelings over the years were justified; that organized religion was utter nonsense and there are no such things as deities worthy of worship. His review of seven major prophets confirms there is a pattern to the fraud they perpetrate in the name of their deities. Wright cautions those who still believe in deities and can't imagine life without a church that this book is not for them. It's for those who know, or suspect, that atheism is more natural and accurate as a life stance than anything to be gained from any organized religion. The World's Seven Biggest Liars exposes the lies the prophets spread and how it is that humankind has been and continues to be their victims.
