3. The lake and trees in this picture are
examples of natural resources because
they support animal and plant life. Many
natural resources can’t be replaced once
they are used up. Conservation is the
protection and wise use of natural
resources so that they can support life on
Earth far into the future.
Natural resources

5. Suppose you have a candy bar. You could
eat the whole candy bar now, or you could
divide it into pieces to eat later. Saving
some of the candy bar to eat later would be
a kind of conservation. You would be
saving, or conserving, your candy bar so
that it would last longer.
Conservationists are people who want to
save Earth’s natural resources so they will
last longer. Conservation is the protection
and wise use of natural resources.

6. TWO MAIN FACTORS
The two main factors that can change
substances into resources are
Time
Technology
Time indicates the different periods
Technology refers the techniques
adoped by the humans.

7. MEANING
Any substance that can be
used to satisfy a need is a
resource. Each one has its
own utility value

8. CLASSIFICATION
• Generally resources are classified into
three broad divisions.They are;
• 1. Natural resources
• 2.Humun resources
• 3. Humun made resources.

15. NATURAL RESOURCES
 Resources are drawn from nature
 (air,water,soil and minerals)
 They are both renewable and non-renewable.
 They are abiotic and non-abiotic.
 The natural substances present on the earth with
out any modifications are called natural resources.

16. HUMAN RESOURCES
► Human beings are the most valuable and a special
resorce
► Education,Health and Skills are the important
factors making the people to become a valuable
resource.
► Therefore we have Human Resource Development
Ministry to improve the quality of the people’s skill.
► Resource development is based on human efforts.

17. HUMAN MADE RESOURCES
►Human made resources are the resources
which are getting value by the efforts
putforth by the human beings.
►The natural substances are changed from
their original form into a developed formby
means of humans’ skill and technology
adopted.
►For example, make buildings, roads
machinery and vehicles

18. CLASSIFICATIONS BASED ON
VARIOUS CRITERIAS
LEVEL OF DEVELOPMENT
►origin------ -living and non living
► stock------amount of resources
available for use.
► distribution----UBIQUITOUS AND
LOCALISED

19. Development and use
►ACTUAL RESOURCES --QUANTITY IS
KNOWNAND USED IN THE
PRESENT.eg.BLACK SOILS IN DECCAN
►POTENTIAL RESOURCES---ENTIRE
QUANTITY MAY NOT BE KNOWN they are
used in future than for present.eg. The
uranium deposits found in ladakh.

20. ORIGIN
►ABIOTIC------Non -living resources like soils
and minerals
►BIOTIC--------Living resources such as
plants and animals

21. EXHAUSTIBILITY
►Renewable--------the resources are able to
get back again eg.water, soiletc.
►Non-renewable-----not able to get back. Eg.
►Minerals like coal .copper etc.

22. DISTRIBUTION OF
RESOURCES
Ubiquitus-----found
everywhere.eg.air we breathe.
Localised ------found only in certain
places. Eg.. Copper deposits in
certain areas.

23. Factors responsible for
the distribution of
resources
 Physical factors like terrain ,
climate and altitude’
 The distribution of resources are
unequal when these factors differ.

24. CONSERVING RESOURCES
Careful utilisation of resources and
giving them to get renewed is
called resource conservation.
It is needed for present and future
purposes.
There are many ways to conserve
the resources
They are ;1.reducing consumption
2.Recycling and reusing things

25. SUSTAINABLE DEVELOPMENT
Carefully utilising resources so that
besides meeting the requirements of
the present, also takes care of future
generations.

26. Some principles
• Careful utilisation of resources
• Minimise the depletion natural
resources
• Brings awareness and change personal
attitude and practices
• Improve the quality of human life
►Sustainable development

27. CONCLUSION
Therefore it is our duty to ensure that :
All uses of renewable resources are
sustainable.
The diversity of life on the earth is
conserved.
The damage to natural environment
system is minimised.
