Ecosystem is the complex network of interactions between living things and their physical as well as biological environment. For humankind, this complex is further extended for social, cultural and psychological components of environment. Population, organization, environment and technology are the four major components of ecosystem. Human population density and human behaviour add further dimensions in studying environmental perspectives and human responses. Three essential components of environment air, water and land, technically known as atmosphere, hydrosphere and lithosphere altogether comprise biosphere. Physical and biological factors of environment influence the survival, growth, development and reproduction of organism. Pollution in biosphere caused by the agents affect the life of organism and dissolute ecological balance. The present volume inscribes the different facets of anthropogenic impacts on environment. Pollutants mostly generated by human activities indiscriminate use of non biodegradable substances, chemicals, industrial wastes, and others debase the natural values of environment and ecology.
Environmental Scientists monitor the quality of the environment, interpret the impact of human actions on ecosystems, and develop strategies and management procedures for restoring balance in ecosystems. Environmentalism is a broad philosophy and social movement focused on a chief concern for the conservation and improvement of the natural environment and human civilization. This present peer reviewed publication, Environment Education : Global issues and Policies is our third venture in this subject of editing a scientific volume. A galaxy of outstanding contributions by the eminent scientists and environmentalists from different parts of the world has enriched the volume. We are grateful to the authors of this volume. They have turned our long fostered dream of having this kind of fascinating volume into reality.
