primitive-society human needs were simple
and limited. In course of time Barter system
prevailed and commodity to commodity
exchange came into existence. So, direct
exchange of goods for goods is known as
barter system. With the passage of time and
growth of civilisation, human wants multiplied.
Neither it was possible to be self-sufficient
nor was it possible to carry on exchange
through the barter system. The importance of
money stems from the fact that it does away
with the main inconveniences of barter
system.
Money came into picture to facilitate
exchange. Now-a-days, we realise the
significance of money in the field of
consumption, production, exchange,
distribution and public finance.
Now-a-days, commodities are exchanged for
money and with that money we can have the
commodities (or services) we require (it is
known as C-M-C exchange system).
However, direct exchange of goods for goods
(barter system) continued for a pretty long
period of time. People experienced the
difficulties of barter system. The difficulties of
barter system like;
1. Lack of double coincidence of wants;
2. Lack of common measure of value;
3. Difficulty of sub-division;
4. Absence of store of value and
5. Difficulty in transfer of value paved the way
for the invention of money.
Money plays a crucial role in the
determination of income, output, employment,
general price level and it is significant in the
field of consumption, distribution, exchange,
public finance etc.
So it is worthwhile to know the meaning of
money.
Fuel Conservation:
God gifted us many things. He made the world and our planet Earth. On Earth, we human are undoubtedly dependent on various things. We’re also dependent to Fuel. Aren’t we? Yes we’re dependent. Fuel is a thing when heated produce energy.
We need various things for making ourselves good such as Food. For cooking food, we need fuel. So, Fuel is very important and its role is indispensable. For example: Food works like a fuel in human body. It gives energy to human body and helps in maintaining the growth and life of human and animals as well.
Fossil Fuels such as coal, petroleum, natural gas are mainly used in industries for various purposes. Electricity, the thing which we need daily as a source of energy is also produced by Fossil fuels. Rapid and Uncontrolled urbanization also has the demand of more Energy which is being produced by fuels. We can’t do much without fuels.
Combustion of fuels has a bad impact on our Environment and led to the pollution. Our environment includes birds, trees, water, air etc. We’re also willingly dependent on our Environment. Environment is clean than only we’ve fresh mind and healthy. Combustion of fossil fuels led the formation of greenhouse gases in the atmosphere. It harms our Environment. The air is mixed with greenhouse gases and we breathe. It effects on our lives and health. It may cause respiratory diseases such as asthma and pulmonary disorder. It may also harm to our ecosystem.
The ozone layer safeguards our earth. It defend us from the ultraviolet rays coming from the sun. The combustion of fuels produces greenhouse gases which led to the depleting of ozone layer faster. This affects the earth. We’ll suffer from it.
We need a peaceful environment and a better place to live. For making our environment safe we should not use vehicles much which need more fuel. Wow! It saves our money. Let’s make people aware of walking and using more and more bicycle not any fuel consuming vehicle. We should switch off engines while waiting for traffic light.
Let’s use more and more LED bulbs and computer monitors. Let’s use CNG engines. Let’s use solar boats while travelling though water bodies. Let’s use clean renewable fuels. Let’s make our lives peaceful by saving fuel. Let’s make our future peaceful and brighter.
