Introduction to environment (harsh gupta)

  1. 1. PRESENTATION ON “INTRODUCTION TO ENVIRONMENT” By, Harsh Gupta 130800119030
  2. 2. Content… • Relationship Between Different Components of Environment. • Man – Environment Relationship. • Impact of Technology on Environment. • Environmental Degradation. • Multidisciplinary Nature of Environmental studies, its Scope And Impact.
  3. 3. Relationship Between Different Components of Environment. ENVIRONMENT BIOTIC ABIOTIC Biotic environment is made up of all living organisms (plants, animals & microorganisms) include their reaction, inter- reaction and interrelated actions. Abiotic environment or physical environment is composed of external factors like temperature, humidity, water, soil, minerals, gases etc. It provides both habitation and raw materials for the synthesis of organic food.
  4. 4. • Interaction between Abiotic and Biotic Components All living organisms depend upon their environment for survival essentials: 1) food 2) shelter 3) breeding site.
  5. 5. Continue.. • These biotic and abiotic components are in dynamic state i.e. they constantly affect each other and cannot be isolated from each other.
  6. 6. Man – Environment Relationship • Relationship between man and environment has variation. This relationship varies from time to time and place to place. • For example.. In the past human being was afraid of lighting and thunder, dense forest, major river and wild animal. • But now human being is interacting with each of them. Variation Time Space
  7. 7. Relief of land : Factors : …. Relief of land Climate Soil Minerals Water • In Himalayas due to steep slop agriculture is done with great difficulties ,industries establishment also. So this place are having very less economy activities. • Therefore very less population. Climate : • Most of the area of the earth are having population density <2 person/km² due to unfavorable climate. • Ex. North Canada, Alaska, Hot Sharah Desert.
  8. 8. Soil : • Fertile soil will attract very dense population. Water : • Earlier settlement and civilization was well developed on the bank of major rivers. Ex. Nile, Ganga river. • Adequate water supply provides irrigation facilities and there by food production is more. Minerals : • The presence of coal, gold, iron, steel, in any area will attract high population. • Ex. Jharkhand in India. • Gold mines in Australia.
  9. 9. Impact Of Technology On Environment Negative Impact • New technology  Industrialization  Urbanization  RAPID EXPLOITATION OF NATURAL RESOURCES. • Innovation of engines  Automobile  Consumption of fossil fuel  Pollution (air). Positive Impact • We have technologies to purify polluted water using RO system, Aqua guard,.. • We have destroyed forest but we have technologies to grow fast growing trees.
  10. 10. Continue… • Invention of Sawing machine  Deforestation. • Fertilizers and Pesticides  Increase in food production  Pollution of land. • Recycling technologies  recycling of paper, plastic etc.. • Technologies to conserve AIR, WATER, LAND, ETC..
  11. 11. Environmental Degradation • It refers to the damage caused to the environment due to both natural and human events. • The overall lowering of environmental qualities due to the damage caused by both natural and human activities in the basic structure of environment at local, regional and global levels adversely affecting all living organisms including man.
  12. 12. Different Types Of Environmental Degradation • WATER • LAND • AIR • FOREST • So on….
  13. 13. • Water Degradation : Degradation in the quality of water is a major & world wide problem. Source : 1. Point source. 2. Non point source. • Land Degradation : Land degradation is a process in which the value of the biophysical environment is affected by combination of human-induced processes acting upon the land.
  14. 14. • Air Degradation : W.H.O has stated Delhi and Kolkata as highly polluted megacities for air qualities. It is due to deforestation, industrialization and urbanization. • Forest Degradation : In India in 1980’s forest cover was about 40% and now it is just 17-18 %..
  15. 15. Multidisciplinary Nature of Environmental Studies, Its Scope And Impact • Environmental studies can be useful to various disciplines : 1. Environmental studies for Engineers : By studying ES engineers can find the sustainable solutions for different global and local environmental problems. 2. Environmental studies for Ecologist : By studying interrelationship between different Biotic and Abiotic components of ecosystem.
  16. 16. Continue… 3. Environmental studies for Hydrologist : By studying these course the Hydrologist can study the quality of land water and aquatic water.
