This book is one of its kinds on environment, in the sense that it touches upon and highlights the modern thinking on environment while incorporating the traditional concepts. The book harps on the basic principles of environment management. It, therefore, reiterates the time tested environment principles. Air pollution has been the most prevalent of all forms of pollution worldwide. The book discusses in detail about indoor air problems, unpleasant odour and deafening noise. The treatment of domestic sewage for improving the environment and health of the people and purification of our river systems by managing our effluents and waste water properly is mainly emphasized upon. The overall emphasis in water management is on restoring its wholesomeness.
Most of the life originates in soil and presents a complex system to support other life forms not originating there. The concepts of the soil fertility, characteristics of soil, pollution in soil, soil erosion and the consequent problems are discussed and soil management principles are then outlined to counter problems of soil degradation. The stratifications and diversity in oceans as also the science of the marine system and issues arising out of global warming, especially those that can be addressed by the oceanic system have also been discussed at length. The emphasis is on bringing about a substantial change in the manner we think. The concept of sustainable development coupled with new thinking shall give the desired results. The issues of efficiency, technology and substitution in whatever we do, thus, gain prime importance.
Production technologies for processes, treatment technologies for treatment of different types of waste and technologies for recycle and recovery of material from waste and newer technologies like nano and bio have been discussed. The role of non-conventional energy sources and systematic approach in environment management cannot be ignored. The book also talks about having the natural ecological systems viz. the forests as well as the industrial ecology for better utilization of waste. The problems like global warming are more due to highly consumptive lifestyle rather than higher level of production leading to emissions. It lays emphasis in not only bringing about changes in lifestyle but also supporting the green production and green practices.
