Total sum of living and nonliving components, influences and events surrounding an organism. It includes:
i) Abiotic or physical milieu including geographic location, terrain, climatic conditions, land, water, atmosphere;
ii) Biotic or organic milieu including plants, animals, bacteria, virus and other organic matter
Environmental Degradation: Act or process of devaluing of and damage to the environment by natural or anthropogenic causes; in other words, rendering the environment a less conducive habitat for the living world due to excessive intervention of man. - 4 major areas of concern are: Damage to marine environment; ozone depletion; Smog and air pollution; Vanishing forests or deforestation.
Causes and effects of Environmental Degradation
Affluence produces effluence-Advancing technology, culture of materialism with increasing numbers is threatening to destroy earth’s biosphere.
Causes:
1. Growing population
2. Rapid urbanization
3. Industrialisation - Examples: Effluents in Yamuna in Delhi, tanneries in Vellore, Dyes and chemicals in Gujarat, ship breaking in Alang
4. Market forces leading to exploitation of resources
5. Growth of consumerism and lack of sensitivity to nature
6. Over exploitation and haphazard use of the environment
7. Technology including tranport
8. Deforestation
9. Desertification
10. Depletion of water resources and fisheries
11. Overgrazing
12. Agricultural practices: Intensive farming, over irrigation, chemical fertilizers and loss of soil quality
13. Industrial negligence(Bhopal gas tragedy, untreated effluents)
14. Pollution –air, noise, land, water
15. Some times due to govt policies-e-g Subsidies for irrigation in India has resulted in over irrigation, salinity
Effects:
1. Global warming-Green house effect
2. Ozone depletion
3. Toxic elements in air, water
4. Smog
5. Diminishing human immunity
6. Cost to health of humans (Respiratory problems, eye , hearing problems), plants and animals
7. Contamination of water leading to damage to aquatic, plant an human life, water borne diseases
8. Agricultural land slowly turns into wasteland
