3. DEFINITION:
A resource which meets the needs of humans
which is obtained from nature is called as natural
resource.
These are classified into biotic & abiotic resources.
BIOTIC RESOURCES:
These are living resources which are replenished.
EX: plants ,animals , forest etc
4.
5. ABIOTIC RESOURCES:
These are non living resources which are not able
to replenish themselves.
EX: minerals , petrol, land etc.
6. Every individual has responsibility to use
natural resources judiciously. This will give
equal opportunity to all to use the resources
for the benefit of mankind. One should not
be selfish to spend the available resources
without thinking of other fellow beings.
There is no limit to spend natural resources
if available plenty but at the same time one
should realize that natural resources are
non-renewable sources. The future also
depends on such resources. Every individual
7. should think himself or herself as a world
think himself or himself as a world citizen.
The whole world is a family and all are inter-
dependant for a better life. The mother
earth has given enough for all to satisfy
minimum wants but not enough to utilize.
Every individual has a role in the
conservation of natural resource like in
using water electricity woods, foods etc.
water is life and every drop is precious
8. similarly every chemical power saved is like
it is produced. Woods should be used so has
not to destroy the forest procurement of
more food than needed is like putting other
starving. Equitable use of resources for
sustainable life styles.
Everyone has the right to live in this world.
All living creatures belong to mother earth
and they all have their shine of resources
available. All these resources like
land, energy, food, mineral, water, forest etc.
have to be distributed in an equitable way
9. sustainable lifestyles of all creatures. The
responsibility lies more on the human
population because they have got the
thinking power and the wisdom to judge
good and had man should realize that
he is not alone in this world. Hence
responsibility should be for all human being
for an equitable use of natural resources for
sustainable use of natural resources for
sustainable life styles of all in this mother
earth.
10. CLASSIFICATION OF NATURAL RESOURCES BASED ON
THEIR AVAILABILITY:
Natural resources are classified into two types.
They are (1)Renewable resources and (2)Non
renewable resources.
Renewable resources:
Renewable resources are resources that can be
produced naturally
1)The resources that can be renewed by
reproduction are called renewable resources.
11. 2) Renewable resources are inexhaustible.
3) Renewable resources are not affected by the
human activities.
4) All biotic resources are renewable.
5) For example: air and water.
12.
13. Non Renewable resources:
1)The resources that are present in fixed quantities are
called non-renewable resources.
2) Non-renewable resources are inexhaustible.
3) Non renewable resources are affected by human
activities.
4) Some abiotic resources are non-renewable.
5) For example- fossil fuels and minerals
14. AFFORESTATION:
Afforestation is the establishment of a forest or stand
of trees in an area where
there was no forest.
Afforestation is the
reestablishment of
forest cover, either
naturally (by natural
.
15. seeding, or root suckers) or artificially (by direct
seeding or planting). Many governments and non-
governmental organizations directly engage in
programs of afforestation to create forests and
biodiversity. In some places, forests need help to
reestablish themselves because of environmental
factors. For example, in arid zones, once forest
cover is destroyed, the land may dry and become
16. inhospitable to new tree growth. Other factors include
overgrazing by livestock, especially animals such as
goats, cows, and over
-harvesting of forest
resources. Together
these may lead to
desertification and
the loss of topsoil;
without soil, forests
17. cannot grow until the long process of soil creation has
been completed - if erosion
allows this. In some tropical
areas, forest cover removal
may result in sealing off the
soil where water doesn’t
penetrates into the soil and
there wont be root growth.
