The 1970s saw a revolution in thinking about energy supplies. No longer were they regarded as cheap, expandable and practically inexhaustible.

In order to understand man’s special relationship with his environment it is necessary to review his more recent evolution briefly. With greater powers for subduing nature and harnessing natural resources for his own ends, mankind had shown alarming growth in numbers. At first the growth rate was slow. The environment has not only been greatly affected by man’s agricultural activities, but also by industrial development. This book is analyzing the tremendous ...
Gaseous substances are released in to the atmosphere, seen as a reservoir with unlimited assimilating capacity. Air being of vital importance, cannot be exploited to the extremes when it becomes unsafe for use. Its capacity to assimilate waste gases is not unlimited. A scientific assessment of air quality and its capacity to assimilate pollutants for safeguarding atmosphere should form the basis of a national air quality management programme. A number of events ...
Some 15,000 year ago man was an unobtrusive species within the living world; this effect on the environment was relatively small and he was well adapted, like other members of the fauna, to the ecosystems of which he was part. But his brain was developing fast and he was becoming much more effective in making stone implements, so he began to make a greater impact on his environment. The tremendous technological achievements of the past century brought many ...

The International Oceanographic Commission defines marine pollution as: “Introduction by man, directly or indirectly, of substances into the marine environment resulting in such deleterious effects as harm to living resources, hazards to human health, or hindrance of marine activities and reduction of amenities.†The productivity of the marine environment and its capacity to receive and disperse pollutants depend on its physical and chemical properties. The ...

Concern over the impact on human health of chemicals in the environment has increased in recent years. Human health and quality of life are strongly influenced by the environment Both environmental and genetic factors, however, are involved in the production of disease. Human beings, at the apex, while representing the finest product of evolution are in no way different from or more important than any other species. In fact, each species has a role and importance ...
Environmental education is an approach to learning, not a subject of study. It endeavours to create a way of thinking requiring people to overcome prejudices as a result of the differing views of fields such as biology, chemistry, economics, social sciences and politics. It leads to the opening of the mind to ever new aspects of the universe. Environmental education thus is a new kind of integrative teaching characterised by encouraging inclusive thinking by a ...

Many people spend large parts of each day indoor-in many cases, 80-90 percent-in a house, an automobile, a waiting room, an office of other workplace, or a confined space accessible to the general public, such as a store or a restaurant. It has shown that indoor exposure to environmental pollutants can be substantial. In the past few decades in the developing countries there have been continuing conflicts, assumed and real, between ecology and development though ...
Many people spend a substantial part of each day indoors-in many cases, 80 to 90 percent-in a house, an automobile, a waiting room, an office or other workplace, or a confined space accessible to the general public, such as a store or a restaurant. It has been shown that indoor exposure to environmental pollutants cab be substantial. Although there is little epidemiologic evidence on the health effects of indoor pollutants, indoor concentration of some pollutants ...
