ABSTRACT
According to the dictionary, the concept of environment refers to all sorts of surroundings and includes material, social and spiritual conditions of living beings. However, in this book the term 'environment' only refers to non-human, living and non-living, physical surroundings. Characteristics of ecosystems, biodiversity, quality of air, water and soil, and stocks of non-renewable resources are included in our concept of the environment. Types of family relationships, conflicting or harmonious relationships in organisations and political systems are excluded from it.
