Describe key concepts on environment (2).pptx

The word environment means surroundings, in which organisms live. Environment and the organisms are two dynamic and complex component of nature. Environment regulates the life of the organisms including human beings.
Human beings interact with the environment more vigorously than other living beings.

1. Key Concepts on Environmental Studies CDT 06105 4th Nov, 2016 Lecture

2. Definition 1. Environment Environment means Surrounding in which we are living. Environment includes those things on which we are directly or indirectly dependent for our survival, whether it is living component like animals, plants or non living component like soil, air water .

3. Definition…. Environmental Protection Act (1986) defined “Environment as the sum total of water, air and land, their interrelationship among themselves and with the human beings, other living beings and property.”

4. Definition…. The word environment means surroundings, in which organisms live. Environment and the organisms are two dynamic and complex component of nature. Environment regulates the life of the organisms including human beings . Human beings interact with the environment more vigorously than other living beings.

5. Definition…. Environment is the sum total of conditions that surrounds us at a given point of time and space. It is comprised of the interacting systems of physical, biological and cultural elements which are interlinked both individually and collectively. Environment is the sum total of conditions in which an organism has to survive or maintain its life process. It influences the growth and development of living forms.

6. Definition…. In other words environment refers to those surroundings that surrounds living beings from all sides and affect their lives in total. It consists of atmosphere, hydrosphere, lithosphere and biosphere. It’s chief components are soil, water, air, organisms and solar energy. It has provided us all the resources for living a comfortable life.

7. Definition…. According to P. Gisbert “Environment is anything immediately surrounding an object and exerting a direct influence on it.” According to E. J. Ross “Environment is an external force which influences us.” Thus, environment refers to anything that is immediately surrounding an object and exerting a direct influence on it. Our environment refers to those thing or agencies which though distinct from us, affect our life or activity.

8. Definition…. The environment is by which man is surrounded and affected by factors which may be natural, artificial, social, biological and psychological.

9. Definition…. 2. Environmental studies Environmental studies are the scientific study of the environmental system and the status of its inherent or induced changes on organisms. It includes not only the study of physical and biological characters of the environment but also the social and cultural factors and the impact of man on environment.

10. Definition…. 3. Environmental Science: It deals with the scientific study of environmental system (air, water, soil and land), the inherent or induced changes on organisms and the environmental damages incurred as a result of human interaction with the environment.

11. Definition…. 4. Environmental Engineering: It deals with the study of technical processes involved in the protection of environment from the potentially deleterious (harmful) effects of human activity and improving the environmental quality for the health and well beings of humans.

12. Definition…. 5. Environmental Management: It promotes due regard for physical, social and economic environment of the enterprise or projects. It encourages planned investment at the start of the production chain rather than forced investment in cleaning up at the end. It generally covers the areas as environment and enterprise objectives, scope, and structure of the environment, interaction of nature, society and the enterprise, environment impact assessment, economics of pollution, prevention, environmental management standards etc.

13. Definition…. 6. Ecology The term “Ecology” was coined by Earnst Haeckel in 1869. It is derived from the Greek words Oikos - home + logos- study. Ecology deals with the study of organisms in their natural home interacting with their surroundings. The surroundings or environment consists of living organisms (biotic) and physical ( abiotic ) components.

14. Purpose/Objectives of studying environment According to UNESCO (1971), the purpose/objectives of studying environment are: (a)Creating the awareness about environmental problems among people. (b)Imparting basic knowledge about the environment and its allied problems. (c)Developing an attitude of concern for the environment.

15. Purpose… (d)Motivating public to participate in environment protection and environment improvement. (e)Acquiring skills to help the concerned individuals in identifying and solving environmental problems. (f) Striving to attain harmony with Nature.

16. Guiding Principles of Environmental Studies: According to UNESCO, the guiding principles of environmental studies should be as follows: (a) Environmental education should be compulsory, right from the primary up to the post graduate stage. (b)Environmental education should have an interdisciplinary approach by including physical, chemical, biological as well as socio-cultural aspects of the environment. It should build a bridge between biology and technology.

17. Principles…. (c)Environmental education should take into account the historical perspective, the current and the potential historical issues. (d)Environmental education should emphasize the importance of sustainable development i.e., economic development without degrading the environment.

18. Principles…. (e)Environmental education should emphasize the necessity of seeking international cooperation in environmental planning. (f)Environmental education should lay more stress on practical activities and first hand experiences.
