Mona and Raju were helping Amma to clean their house. 
“Look at all these things…. clothes, utensils, foodgrains, 
combs, this bottle of honey, books…..Each of these has a 
use,” said Mona. “That is why they are important,” said 
Amma. “These are resources…..”. “What is a resource?” 
was Raju’s question to Amma. “Anything that can be used 
to satisfy a need is a resource”, replied amma. “Look around 
you and observe, you will be able to identify many types of 
resources. The water you drink when you are thirsty, the 
electricity you use in your house, the rickshaw you use to 
get home from school, the textbook you use to study are all 
resources. Your father has prepared a tasty snack for you. 
The fresh vegetables he has used are also a resource”.
Water, electricity, rickshaw, vegetable and textbook 
have something in common. They have all been used by 
you, so they have utility. Utility or usability is what makes 
an object or substance a resource.
“How does something become a resource?” Raju now 
wanted to know. Amma told the children that things become 
resources only when they have a value. “Its use or utility gives 
it a value. All resources have some value.” said Amma.      
Value means worth. Some resources have economic 
value, some do not. For example, metals may have an 
economic value, a beautiful landscape may not. But both 
are important and satisfy human needs.
Some resources can become economically valuable 
with time. Your grandmother’s home remedies have no 
commercial value today. But if they are patented and sold by 
a medical firm tomorrow, they could become economically 
valuable.

2 ResouRces and d evelopment Time and technology are two important factors that 
can change substances into resources. Both are related 
to the needs of the people. People themselves are the 
most important resource. It is their ideas, knowledge, 
inventions and discoveries that lead to the creation of 
more resources. Each discovery or invention leads to many 
others. The discovery of fire led to the practice of cooking 
and other processes while the invention of the wheel 
ultimately resulted in development of 
newer modes of transport. The technology 
to create hydroelectricity 
has turned energy in fast 
flowing water into an 
important resource.
Types of ResouRces   
Resources are generally classified into 
natural, human made and human.
Natural Resources
Resources that are drawn from Nature and used without 
much modification are called natural resources. The 
air we breathe, the water in our rivers and lakes, the 
soils, minerals are all natural resources. Many of these 
resources are free gifts of nature and can be used directly. 
In some cases tools and technology may be needed to 
use a natural resource in the best possible way.
Natural resources can be broadly categorised into 
renewable and non-renewable resources.
Renewable resources are those which get renewed or 
replenished quickly. Some of these are unlimited and are 
not affected by human activities, such as solar and wind 
energy. Yet careless use of certain renewable resources 
like water, soil and forest can affect their stock. Water 
seems to be an unlimited renewable resource. But 
shortage and drying up of natural water sources is a 
major problem in many parts of the world today.
Non-renewable resources are those which have a 
limited stock. Once the stocks are exhausted it may 
take thousands of years to be renewed or replenished. 
Since this period is much more than human life spans, 
  “So I am a 
  resource too!”
“A very 
valuable one!”

such resources are considered non-renewable. Coal, 
petroleum and natural gas are some examples.
The distribution of natural resources depends 
upon number of physical factors like terrain, climate 
and altitude. The distribution of resources is unequal 
because these factors differ so much over the earth.
Human Made Resources 
Sometimes, natural substances become resources only 
when their original form has been changed. Iron ore 
was not a resource until people learnt to extract iron 
from it. People use natural resources to make buildings, 
bridges, roads, machinery and vehicles, which are 
known as human made resources. Technology is also 
a human made resource.
“So people like us use natural resources to make human 
made resources,” said Mona nodding in understanding.

c onseRving ResouRces Mona had a nightmare. She dreamt that all 
the water on the earth had dried up and all the 
trees cut down. There was no shade and nothing to 
eat or drink. People were suffering and roaming around 
desperately looking for food and shade. 
She told her mother about the dream. “Amma can this 
really happen?” she asked.
“Yes,” Amma replied. “If we are not careful then even 
renewable resources can become very scarce and the 
non-renewable ones can definitely get exhausted”. “What 
can we do about it,” Raju asked. “Lots,” replied Amma. 
Using resources carefully and giving them time to get 
renewed is called resource conservation. Balancing 
the need to use resources and also conserve them for 
the future is called sustainable development. There 
are many ways of conserving resources. Each person 
can contribute by reducing consumption, recycling and 
reusing thing. Ultimately it makes a difference because 
all our lives are linked. 
That evening the children and their friends 
made packets and shopping bags out of old 
newspapers, discarded clothes and baskets 
from bamboo sticks. “We will give a few to every 
family we know,” said Mona. “After all it is for 
a very good cause,” said Mustafa, “To save our 
resources and to keep our earth alive”. 
“I am going to be very careful not to waste 
paper,” said Jessy. “Many trees are cut down to 
make paper,” she explained.
“I will see that electricity is not wasted in 
my house,” shouted Mustafa. “Electricity comes 
from water and coal.”
