Natural Resources

Any material which can betransformed in a way that itbecomes more valuable and useful,can be termed as a resource.

The resources occurring in nature

are called natural resources. Soil, water and vegetation are three

basic natural resources.

soil

Soil is a natural resource, which isrequired for production of food,industrial raw materials as well as for

generation of energy resources. It is also a natural value, which is

protected as natural heritage.

Deforestation causes loss of soil Therefore , soil is lack of nutrients and

desertification may occur.

water

Water is a common natural resourcethat is essential for the survival of allknown forms of life.

Industrial wastes are discharged intothe water bodies and has caused seriouswater pollution.

Many aquatic lives are threatened.Besides, the wasteful use of industrialand domestic water may lead todeficiency in ground water reserve.

vegetation

It is also a natural resource and is used asfuel and food both.

The degraded vegetation is used as fuel

and the fresh ones as food. petrol, natural gas etc. are formed from

plants.

According to the statistics, the loss intrees is more than 1 billion hectares everyyear. Many organisms that live on treeslose their habitat due to deforestation.

sun

It is a source of light energy.This energy is used by all life forms .

The sun has produced energy for billions ofyears. Solar energy is the suns rays (solar

radiation) that reach the earth. Solar energy can be converted into other

forms of energy, such as heat andelectricity. In the 1830s, the British

astronomer John Herschel used a solarthermal collector box (a device that absorbssunlight to collect heat) to cook food duringan expedition to Africa. Today, people usethe sun's energy for lots of things.

Types of resources

Based on continual utility:

- renewable resources

- non-renewable resources

- cyclic resources

Based on origin:- biotic resources

- abiotic resources

Renewable resources

They can be renewed along with theirexploitation i.e.always available foruse.

There are also non-living resources that

are renewable, such as hydroelectricpower, solar power, biomass fuel, andwind power.

If renewable resources are consumed

at a rate above their natural rate ofreplacement, the standing stock willdiminish and eventually run out.

e.g. trees,animals, soil, water.etc.

Non-renewable resources

A non-renewable resource is a naturalresource that exists in a fixed amount thatcannot be re-made, re-grown or regeneratedas fast as it is consumed and used up.

Some non-renewable resources can berenewable but take an extremely long time torenew. Fossil fuels, for example, take millionsof years to form and so are not practicallyconsidered 'renewable'.

E.g.oil, coal, natural gas etc.

Cyclic resources

They do not have any final use andcan be used continuously.

e.g. Water

Biotic resources

They are obtained from biosphere ororganic matter.

E.g. animals, plants, etc.

Abiotic resources

They are obtained from non-living

inorganic matter.

E.g. land, water, iron, copper,minerals, rocks etc.

Uses of natural resources

Coal, oil and natural gas

provide us with almost all of

the energy we use to light,heat and run our world.

Minerals are ingredients in

almost all of the products we

use from fertilizer toplastics, from toothpaste to

kitty litter, from knives to

plates.

takes into consideration

various cross-sectoral issues having

a direct bearing onconservation and sustainable uses
