NEED FOR PUBLIC AWARENESS

1. Increasing population, urbanization and poverty have generated pressure on the natural resourses and lead to a degradation of the environment. 
2. To prevent the environment from further degradation ,the supreme court has ordered and initiated environment protection awareness through government and non government agencies to take part in protecting our environment. 
3. Environmental pollution cannot prevented by laws alone. Public participation is equally important with regard to environmental protection. 
4. Environmental education is a process of learning by giving an overall perspective of knowledge and awareness of the environment. 
5. It sensitizes the society about environmental issues and challenges interested individuals to develop skills and expertise thereby providing appropriate solution. 
6. Climate change, loss of diversity ,ozone layer depletion, illegal trade of endangered species, destruction of habitats, land degradation, environmental pollution, storm water pose a serious threat to ecosystem in forest, rural, urban and marine ecosystem. 
7. Both formal and informal education on the environment will give the interested individual the knowledge, values, skills and tools needed to the face the environmental challenges on a local and global level

MULTIDISCIPLINARY NATURE OF ENVIRONMENTAL STUDIES

The Environment studies is a multi-disciplinary science because it comprises various 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. It studies about the sources, reactions, transport, effect and fate of physical and biological species in the air, water, soil and the effect of from human activity upon these. 

As the environment is complex and actually made up of many different environments like natural, constructed and cultural environments, environmental studies is inter disciplinary in nature including the study of biology, geology, politics, policy studies, law, religion engineering, chemistry and economics to understand the humanity’s effects on the natural world. 

This subject educates the students to appreciate the complexity of environmental issues and citizens and experts in many fields. 

By studying environmental science, students may develop a breadth of the interdisciplinary and methodological knowledge in the environmental fields that enables them to facilitate the definition and solution of environmental problems

Environmental studies as a subject has a wide scope. It includes a large number of areas and aspects.

which may be summarized as follows:

• Natural resources- their conservation and management 
• Ecology and Biodiversity 
• Environmental pollution and control 
• Human population and environment 
• Social issues in relation to development and environment

Several career options have emerged in these fields that are broadly categorized as: 

• Research and development in environment 
• Green advocacy 
• Green marketing 
• Green media 
• Environmental consultancy

1. Atmosphere- The Atmosphere is theProtective blanket of gases surrounding the earth. It sustains life on the earth and saves it from the hostile environment of outer space.

2. Hydrosphere- The Hydrosphere comprises all types of water resources oceans, seas, lakes, rivers, streams, reservoir, polar icecaps, glaciers, and ground water

3. Lithosphere- Lithosphere is the outer mantle of the solid earth. It Contains various types of soils and rocks on the earth.

4. Biosphere- Biosphere composed of all living organisms and their interactions with the environment

Environmental factors greatly influence every organism and their activities. The environment studies enlighten us, about the importance of protection and conservation of our natural resources, indiscriminate release of pollution into the environment etc.

Environment studies have become significant for the following reasons:

1. Environment Issues are being global: It has been well recognized that environment issues like global warming, ozone depletion, acid rain, marine pollution and loss of biodiversity are not merely national issues but are global issues and hence require international efforts to solve them.

2. Problems Cropped in The Wake of Development: Development, in its wake gave birth to Urbanization, Industrial Growth, Transportation Systems, Agriculture and Housing etc. However, it has become phased out in the developed world.

3. Explosively Increase in Pollution: World census reflects that one in every seven persons in this plant lives in India. Evidently with 16 per cent of the world's population and only 24 per cent of its land area, there is a heavy pressure on the natural resources including land.

4. Need for An Alternative Solution: It is essential, specially for developing countries to find alternative paths to an alternative goal. (1) A goal, which ultimately is the true goal of development an environmentally sound and sustainable development. (2) A goal common to all citizens of our earth.

5. Need For Wise Planning of Development: Our survival and sustenance depend. Resources withdraw, processing and use of the product have all to be synchronized with the ecological cycles in any plan of development. Our actions should be planned ecologically for the sustenance of the environment and development.
