RESOURCES
• A resource is anything
we get from the
environment to meet
our needs and desires.
• It may be any useful
information,material or
service.
• Thus, any part of our natural
environment,such as
land,water,air,minerals,forest,
wildlife,fish or even human
population that man utilise to
promote his welfare are
regarded as natural resources.
• The five basic ecological
variables:energy,matter,space,
time and diversity are
sometimes combinedly called
natural resources.
CLASSIFICATION OF RESOURCES:
Natural resources can e broadly divided in two
categories:
I. Biotic (or living) Resources:
eg:Forest,Fish,Wildlife,Agriculture,etc.
II. Abiotic(nonliving) Resources:
eg:Land,water,minerals,etc.
• Furthermore,the natural resources can be divided
into two types accordingly to the availability.

RENEWABLE RESOURCES
Renewable resources are natural resources
that can be replenished in a short period of
time.
● Solar ● Geothermal
● Wind ● Biomass
● Water
Renewable Resources
• Renewable resources are those that are
replenished through relatively rapid natural
cycles.
• Examples :
1) Oxygen in the air,which is replenished
through photosynthesis.
2) Fresh water which is replenished through
water cycle.
3) All biological products(Food,Fish,Timber
etc.)which are replenished through natural
cycles.
4) Solar energy is also considered as
renewable as on a human time scale it is
inexhaustible.
NON RENEWABLE RESOURCES
A nonrenewable resource is a
natural resource that cannot be
re-made or re-grown at a scale
comparable to its consumption.
NON RENEWABLE RESOURCES
NON-RENEWABLE
RESOURCES:
{a}Non-Renewable resources
that can be recycled.
{b}Non-Renewable resources
that cannot be recycled.
Non-Renewable Resources that cannot
be recycled:
• The includes all non-energy mineral resources
which occur in the earth’s crust.
• Example:
1) Ores of copper,aluminium,mercury and other
metals.
2) Deposits of fertilizer nutrients such as
phosphate rock and potassium.
3) Minerals that are used in their natural states
such as asbestos,clay,mica,etc.As this deposits
are mined,5they are not replaced and hence
such minerals are considered non-renewable.
Non-renewable Resources that can be
recycled:
• Resources that exist in a fixed quantity in earth’s
crust and thus theoretically can be completely
used are called non-renewable resources.
• On a time-scale of millions to billions of years
such resources can be renewed by geological
process.
• Non-renewable resources that cannot be recycled
are those mineral energy resources,namely,fossil
fuels that presently supply better than 90% of our
energy and uranium that is used for nuclear
power.

CONSERVATION
DESTRUCTION:
CONSERVATION:
•
• Conservation is sustainable use of
natural resources.
• It is derived from two latin words
‘con’(together) and ‘servare’(to
keep or guard) thus the meaning
‘to keep together’.
• The true aim of conservation is
1. Preserevation of quality of
environment.
2. To ensure continuous and
balanced cycle of harvest and
renewal.
Renewable resources though
renewable but it may be possible that
rate of utilization is more than rate at
which is being renewed.
• Example:
i.
In many developed
countries,diversed old growth
forest is being replaced by single
species tree plantation with much
less diverse second growth forest
and wild life diversity.
ii.
Thousands of life species become
extinct each year because of
human activities.
Measures…………
 Stopping deforestation and increasing afforestation.
 Vertical development of cities so that less land is used for
accommodating more number of people.
 Rain water harvesting, construction of check dams etc.
 Recycling and reuse of resources whenever possible.
 By optimum use of resources.
 Using more and more solar energy as it can be considered
inexhaustable.
 Development of new technologies to use alternative fuels
like hydrogen gas,natural gas etc.
 Forest and wildlife resources can be conserved by forming
National park,Sanctuary and enacting strict laws.
