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.
