The book provides the basic concept of environment and incorporates the recent material available to serve as a source book. The chapters in this book present a background of the solar system, ecology, biosphere, environment and man's dominance in the biosphere. The factors governing the life in the biosphere have been discussed and an attempt is being made to find out the possibility of life, if it exists, elsewhere in the universe.

The consecutive chapters deal with various other aspects such as coastal zone management, deforestation, impact of mining on fisheries, wild life management, termite pest control, bioremediation of wastes by hydrophytes, role of remote sensing in environment and management of food protection. The energy crisis has been given a special treatment in order to understand the problem and to find out solution without disturbing the ecosystem stability.
