The science of Environment studies is a multi-disciplinary science because it consists of different branches of studies like chemistry, physics, medical science, life science, agriculture, public health, sanitary engineering etc. It is the science of physical phenomena in the environment—the studies of the sources, reactions, transport, effect and fate of physical a biological species in the air, water and soil and the effect of from human activity upon these. If we use any environmental resource such as ground water beyond its limit of replacement, we may lose it forever. Therefore, there is a need to create ‘awareness’ about Environmental protection. While efforts are being made at the national and international level to safeguard our environment, it is also the responsibility of every citizen to use our environmental resources with care and protect them from degradation.
“Environmental Education and Policy” deals with the factors of environmental degradation and the importance of environmental conservation. The environmental degradation poses a great danger to man's own survival. It should be realized, sooner than later, that conservation and improvement of the environment are vital for the survival, and well-being of mankind. Natural resources of land, air and water have to be used wisely as a trust to ensure a healthy environment for the present and future generations. It has been well recognised that environment issues like global warming and ozone depletion, acid rain, marine pollution and biodiversity are not merely national issues but are global issues and hence must be tackled with international efforts and cooperation. While demand for environmental protection is growing, it comes at a cost. The costs and benefits of taking action or not must therefore are estimated when environmental legislation is being drafted. However, it is rare for the costs and benefits – particularly the benefits – that actually materialize to be assessed after the policy has been implemented. Where they are, it appears that costs tend to be overestimated, possibly owing to both asymmetric information and a tendency to underestimate innovation and progress in abatement technologies. This novel edition examines the nature, scope and importance of environmental education. It inspects environmental pollution, ozone layer depletion, biodiversity conservation role, causes, and effects of environmental hazards critically.
