Ecology And The Quality Of Our Environment

The relevance of ecology to human affairs; Historical aspects of ecology; Ecological principles; Population ecology; Community ecology; Ecology and the human future.

This 2nd edition of Understanding Our Environment has been reworked and greatly updated, providing a modern introductory level text for students of pollution and environmental chemistry. The book describes the basic concepts in relation to the chemistry of the atmosphere, freshwaters, oceans and soils, as well as the ways in which pollutants behave in these media (exemplified by case studies based upon topical environmental problems). It also examines the transfer of pollutants between different environmental compartments, the monitoring of the environment, the ecological and human health effects of chemical pollution, economics and regulatory control. Again case studies are used throughout. This unique introductory text is essential reading for students on undergraduate and first year postgraduate courses dealing with pollution and environmental chemistry, as well as for scientists and engineers in industry, public service and consultancy who require a basic understanding of environmental processes.

Global society in the 21st century is facing challenges of improving the quality of air, water, soil and the environment and maintaining the ecological balance. Environmental pollution, thus, has become a major global concern. The modern growth of industrialization, urbanization, modern agricultural development and energy generation has resulted in the indiscriminate exploitation of natural resources for fulfilling human desires and needs, which has contributed in disturbing the ecological balance on which the quality of our environment depends. Human beings, in the truest sense, are the product of their environment. The man-environment relationship indicates that pollution and deterioration of the environment have a social origin. The modern technological advancements in chemical processes/operations have generated new products, resulting in new pollutants in such abundant levels that they are above the self-cleaning capacity of the environment. One of the major issues in recent times is the threat tohuman lives due to the progressive deterioration of the environment from various sources. The impact of the pollutants on the environment will be significant when the accumulated pollutants load will exceed the carrying capacity of the receiving environment. Sustainable development envisages the use of natural resources, such as forests, land, water and fisheries, in a sustainable manner without causing changes in our natural world. The Rio de Janeiro-Earth Summit, held in Brazil in 1992, focused on sustainable development to encourage respect and concern for the use of natural resources in a sustainable manner for the protection of the environment. This book will be beneficial as a source of educational material to post-graduate research scholars, teachers and industrial personnel for maintaining the balance in the use of natural sources for sustainable development.

After a period of relative silence, recent years have been marked by an upswing of interest in environmental issues. The publication of the report of the World Commission on Environment and Development on 'Our Common Future' (1987) has acted as a catalyst for a revival of the environmental awareness, not only regarding local and daily pollution problems, but also -and in particular- regarding global environmental decay and threats to a sustainable development. In a recent study by W.M. Stigliani et al., on 'Future Environments for Europe' (Executive Rep~rt 15, IIASA, Laxenburg, 1989) the environmental implications of various alternative socioeconomic development pathways with respect to eleven environmental issues that could become major problems in the future are analysed. These issues include: Managing water resources in an era of climate change. Acidification of soils and lakes in Europe. Long-term forestry management and the possibility of a future shortfall in wood supply. Areas of Europe marginalized by mainstream economic and agricultural development. Sea level rise. Chemical pollution of coastal waters. Toxic materials buildup and the potential for chemical time bombs. Non-point-source emissions of potentially toxic substances. Transportation growth versus air quality. Decreasing multi-functionally of land owing to urban and suburban land development. Increasing summer demand for electricity, and the impact on air quality.

Environmental Health: Ecological Perspectives is intended as an environmental health text for both undergraduate and graduate levels. This text provides balanced coverage of how humans are affected by the quality of air, water, and food as well as how humans affect these survival necessities. The evolution and prosperity of the human species has resulted in concerns about pollution, overpopulation, and several other issues that are having a harmful effect on humans and our environment. This knowledge, along with an understanding of the legislation and history of environmental issues, will help students to make positive changes in their behavior and in the world around them.
