It is in this context that this book has been prepared for Class XII students of CBSE affiliated schools. The main aim of the authors has been to develop awareness about the relationship between development and environment, various kinds of pollution-their sources and effects on our environment and energy situation particularly in our own country. Effort has been made to make the students realise that modernity is just an illusion a condition achieved of environment. Our traditional values and simple living is the only way to save our environment from further deterioration.
Suggestions for further improvement of the book shall be greatfully acknowledged.
