Geology and Environment in Britain and Ireland - edizione con copertina flessibile

A complete introductory text on an increasingly popular subject, "Geology and Environment in Britain and Ireland" aims to provide suitably broad coverage for students requiring a treatment clearly focused on familiar examples but retaining a global perspective. The book summarizes for Earth and environmental scientists the ways in which geology relates to the natural environment and to the human activities that it supports. The natural environment is more than the oceans, the atmosphere and the diversity of the land surface. It extends below the ground and stretches back in time through the Earth's history. These environmental dimensions are the concern of geology. First, the book summarizes the geological influences on society through control of landscape and human geography, and through the threats posed by hazards such as landslides, subsidence and earthquakes. Next the many Earth resources that support human activity are described: land, water, construction materials, minerals, coal, oil and gas. How are they formed or replenished? Which resources are sustainable for use over more than the immediate geological future? Thirdly, the impacts of human activity on the Earth are examined - the results of extracting geological resources, of intentionally engineering the environment, and of carelessly polluting land and underground water supplies. Perhaps most serious of all is atmospheric pollution caused by burning geological fuels, threatening global change on scales only familiar from the geological record. This book is published at a pivotal point in the history of geology. Scientists who, for a century and a half, have been preoccupied with finding Earth resources are increasingly being asked where on Earth to dispose of the effluents from using them. "Geology and Environment in Britain and Ireland" provides a compact, abundantly illustrated summary of both sides of this dilemma. Its final chapter breaks new ground in opening a debate on the ethical basis of appl
