The impact of population on various domains of environment in reality, could be different. In a few cases, the impact would be more deleterious than the predictions made through the EIA study. This may be due to various extraneous climatological and environmental factors not attributable to the particular industry. The regulatory mechanism of environmental compliance is gradually becoming more and more comprehensive. The new regulations and standards are being stipulated consequent to a better understanding of the environmental implications, at such a pace that, it would soon render the existing system archaic.

Various methods and practices of pollution monitoring and control are dealt with exhaustively in this book. The succinct information contained in various topics likes-Air pollution monitoring; air pollution control; Ganga action plan; waste water treatment; water supply management; industrial pollution abatement; environmental audit will prove informative and useful to experts and laymen alike.

Population is an interacting, or potentially interacting group of individuals usually of the same species. Some of the most important aspects of population structure are population size, density, spatial distribution age and sex rates, breeding structure and social organization. Population sizes may vary from a few individuals to millions of individuals. The population of whooping cranes (Grus American) numbers about 50 individuals a single group of birds barely cloning to existence. Other rare and endangered species around the world also represent very small populations. Population and community ecology is in its all dimensions is discussed in this book. Main themes elaborately dealt with are: Ecology of populations; Social behaviour; Population growth; The psycho-social consequences of crowding; community ecology; and man's future etc.

What is the carrying capacity of the earth for man? In other words, what are the limits of the life support capabilities of the earth in terms of human population? Are the behaviourists' concern. What are the tolerance levels of man to the pressures generated by his own societies? In other words, if man is his own worst enemy, does this lead to his self destruction? The impact of population on environment is competently assessed in this book. The major topics X-rayed pros and cons are: Introduction; population interaction; population growth; crowding; population characteristics; population policy; and future of man etc.

Population process-births, deaths, and movements of individuals-express the varied interactions of organisms with their environments. Evolution by natural selection and the regulation of community structure and ecosystem function transcend the individual organism and cab be comprehended only in terms of the dynamics of populations.

For many purposes one may determine average birth and death rates for small samples of individuals and multiply them by the total population size to characterize the overall dynamics of a population. But populations also heterogeneous. Genetic variation in the interaction of individuals with their environments results in evolution. Variation in the suitability of habitat leads to parallel variation in population density and may determine the net movement of individuals within the population.

A veritable mine of information, this book encompasses authoritative information on a number of vital issues like-population structure; social behaviour; fluctuations; population regulation; population growth; population ecology; future of man etc.
