Environmental studies is a multidisciplinary field that draws from various areas like science, humanities, and social sciences. It involves the study of interactions between natural resources, ecosystems, human populations, and the environment. The document discusses the multidisciplinary nature of environmental studies and outlines some of its key components like natural resources, ecology, pollution, social issues, and population studies. It also provides examples of different types of natural resources like forests, water, minerals, and energy, and discusses issues like deforestation, water pollution, mining impacts, floods, and droughts.

2.  Environment
 Environment is ‘a word which describes, in the aggregate, all of the
extrinsic factors influences and condition, which affects the life, nature,
behaviour and the growth, development and maturation of living
organisms’.
 Environment is the aggregate of physical, chemical, biological and social
components on earth which are capable of causing direct or indirect effects
in the short or long term on living and non living things and their activities.
 Environment covers all the outside factors that have acted on the individual
since he began life

4.  Multidisciplinary Nature Of Environmental
Studies
 Environmental studies is a multidisciplinary programme created to promote the study of
our natural surrounding.
 Study of environmental components is multi disciplinary in nature, since it includes all
disciplinary such as science, humanities, commerce, meteorology, geography and other
disciplines.

7.  Resources
 Any material which is part of earth and satisfy human need and value is called as
resource.
 Examples: rocks, minerals, soil, plant and animals etc.
 Types of resources:
 Natural resources
 Human resources
 Man made resources

8.  Natural Resources
 It is the form of energy/matter which is available in the earth and get used by living thing.
 E.g. air, water, soil, minerals, wildlife etc.
 Category of natural resource
 Renewable
 Non- renewable

9.  Renewable & Non renewable
sources
 Renewable: These are resources which are renewed fastly and are not
affected by human activity.
 Examples: solar energy, water, biomass etc.
 Non- renewable: these are resources which are not renewed and are
affected by human activity.
 Examples: coal, oil, natural gas, nuclear power etc.

12.  Forest resources
 A forest, a biotic community with predominance
 of trees is an important renewable natural resource.
 Benefits of forests:
1. clean water
2. Improve air quality
3. Shelter
4. Conversion of CO2 into wood
5. transform degraded areas.

13. Deforestation
 Deforestation is removal or
reduction in forest cover.
 Effects of deforestation :
 Loss of natural habitat
 Increase in frequency of natural
disasters
 Change in climatic condition
 Land degradation
 Increase socio economic problems
 Controlling deforestation:
 Reforestation is also being
encouraged
 Special legislation to protect forest
land
 Environment clearance is mandatory
for big industry

14. Water resources
 Water resources contains oceans, sea, rivers,
ponds, lakes etc.
 Use and over exploitation of surface and
ground water
 Waste and by-product from industries
 Disposal of municipal waste in river cause major
loss of clean water
 Agricultural waste, pesticides, fertilizers.

15. Floods & Droughts
 Floods refers to the presence of unusually
large amount of water at any place or more
water that can be handled by the drainage
of the rea. The various types of foods are,
 Flash floods
 River floods
 Coastal floods
 Drought is a condition in which a region
suffers from a severe scarcity of water.
 Drought changes routine weather pattern
 Affect human health
 migration

16. Mineral resource
 Minerals are naturally occurring chemical compounds, which are formed
through inorganic process under the crust of the earth.
 Types of minerals:
1. Metallic minerals: copper, aluminium, iron
2. Industrial minerals: lime, potash, salt
3. Construction mineral: sand , stone, gavels
4. Energy minerals: coal , gas, oil

17. Mining effects on environment
 Pollute the environment
 Produces large waste
 Destruction of forest
 Soil erosion
 Lowers water table
 Onshore mining affects marine life
 Emission of radioactive pollutants
