கேடறியாக் கெட்ட இடத்தும் வளங்குன்றா நாடென்ப நாட்டின் தலை. குறள் 736
எந்த வகையிலும் கெடுதலை அறியாமல், ஒருவேளை கெடுதல் ஏற்படினும் அதனை சீர்செய்யுமளவிற்கு வளங்குன்றா நிலையில் உள்ள நாடுதான் நாடுகளிலேயே தலை சிறந்ததாகும்.

Kulalee was lying in her bed to see if her father would enter her room. She wanted her report card to be signed. There was no symptom of coming of her father. She jumped out of her bed and ran to her mother in the kitchen.

Kulalee: Amma where is Appa?
Amma: Today he has 'overtime' and he has left early.
Kulalee: Overtime what is that?
Amma: Working more hours than the actual working hours is called overtime. Your father's boss wants him to manufacture a few more solar panels because they have some urgent orders.
Kulalee: He should have told me last night. My progress report has to be signed.
Amma: Enough of that. Now go have your bath. I'll sign your report this time.
Kulalee: Amma, thank you ma. One more question. What does he make the solar panels from?
Amma: Let me explain for you to understand. Silicon, extracted from sand, a natural resource, is used in making PV cells. It converts solar energy into electrical energy.

Kulalee: Natural resource, what do you mean by it?

Amma: All things useful to man is resource. And if it is directly from nature we call it natural resource.

Kulalee: Then what kind of work does father do?

Amma: He is a manufacturer of things by using natural resources.

Kulalee: Can we called the manufactured goods as manmade resources?

Amma: Yes, they are called as manmade resources.
Kulalee: Ok amma. It's getting late. Let me get ready.

Resource

Resource is anything that fulfills human needs. When anything is of some use it becomes valuable. All resources have value. The value can be either commercial or non-commercial. Commercial resources have great economic value. (example) Petroleum. The Non-commercial resources are very abundant in availability (example) Air.

HOTS

Do all the items in your shopping list have commercial value?

HOTS

Is the tilt of the solar panels same everywhere on Earth?

Resources can be natural, man-made and human resources.

1. NATURAL RESOURCES

All resources that have been directly provided by nature are called Natural resources. The air, water, soil, minerals, natural vegetation and wild life around us are all-natural resources. The use of any natural resource depends on the place it is available, the form in which it is available and the technology necessary to avail it.

CLASSIFICATION OF NATURAL RESOURCES

Natural resources can be classified into different groups depending on origin, development, renewability, distribution, ownership etc.

A. ON THE BASIS OF ORIGIN:

On the basis of origin, resources can be classified into biotic and abiotic resources.

one. All living resources are biotic resources, plants, animals and other micro organisms are biotic resources.

two. Abiotic resources are non-living things. Land, water, air and minerals are abiotic resources.

The biotic resources were mere substances till they were recognized by humans. According to the human needs the substances were collected by the ancient men and preserved for use. In the beginning, man had only three basic needs-food, clothing and shelter. He collected things through primary activities such as hunting, food gathering, fishing and forestry. Later when food became scarce, they had to cultivate and that became agriculture and the cattle were also reared on their farms to fulfill their basic needs.

The abiotic resources were also sought after by the early men. They went in search of better landforms where they had enough water resources for agriculture and their cattle. They were inneed of tools right from hunting to agriculture. Primarily the tools were only made of stones. Later man dug the earth for better abiotic resources and found copper first and iron later. He also mined precious metals simultaneously for making ornaments. Later mining became one of the leading primary activities and still holds an important place among the economic activities.

B. ON THE BASIS OF DEVELOPMENT:

Based on the level of development, resources can be divided into actual and potential resources.

One. Actual resources are resources that are being used and the quantity available is known. (example) Coal at Neyveli.

Two. Potential resources are resources that are not being used in the present and its quantity and location are not known. The technology to extract such resources is also yet to be developed. (e.g.) Marine yeast found in the Bay of Bengal and Arabian Sea.

C. ON THE BASIS OF RENEWABILITY:

On the basis of renewability resources can be classified as renewable resources and non-renewable resources.

One. Resources once consumed can be renewed with the passage of time are called renewable resources. (example) Air, Water, Sunlight. Misuse of such resources can also limit its available quantity. So, they have to be used wisely.

Two. The resources which cannot be immediately renewed once they are depleted are called non renewable resources. They become exhausted after use and the time they take to replace does not match the life cycle. Example: Coal, petroleum, natural gas and other minerals.

HOTS

Find out what other resources can renew themselves?

The resources which cannot renew themselves are either scarce or totally absent. So, man is in search of new resources and is conducting several researches. He confirms that a substance is a resource only after research. He tries to harness it and also searches the regions where it may be found in. They are potential resources. Wind energy is one such example. The places where the wind energy can be utilized are still unknown.

HOTS

How did coal originate?

D. ON THE BASIS OF DISTRIBUTION

On the basis of distribution, resources can be classified into localized resources and universal resources.

One. When resources are present in specific regions they are called localized resources. (example) Minerals.

Two. Some resources are present everywhere Such resources are called universal resources. (example) Sunlight and air.

Activity 2

Which region or continent does each of these animals belong to?

E. ON THE BASIS OF OWNERSHIP

Based on ownership resources can be classified into Individual resources, Community-owned resources, National resources and International resources.

one. Individual resources are resources privately owned by individuals. (example) Farmland.

two. Community-owned resources are resources which can be utilised by all the members of the community. (example) Public parks.

Three. National resources are resources within the political boundaries and oceanic area of a country. (example) Tropical forest regions of India.

Four. International resources are all oceanic resources found in the open ocean. Resources found in this region can be utilized only after an international agreement. (example) Ambergris.

2. MAN-MADE RESOURCES:

Natural resources are modified or processed by technology into man-made resources. (example) sugarcane processed to get sugar. All structures built by man can also be called man-made resources. (example) Bridges, Houses, Roads. This transforming of raw materials into finished goods is called Secondary Activities. Man's skills and ideas are the basic requirements for these activities.

Activity 3

What natural resources are necessary to lay a road?

3. HUMAN RESOURCE

Human resources are groups of individuals who use nature to create more resources. Though human beings are basically natural resources, we classify human beings separately. Education health, knowledge and skill have made them a valuable resource. (example) Doctors, Teachers, Scientists. Tertiary activities are basically concerned with the distribution of primary and secondary products through a system of transport and trade (example) Banking, Trade and Communications. The quantity and quality of institutions and organizations involved in making the professionals decide the human resource of a country.

Activity 4

Identify the personalities and professionals

Gandhian thought on Resources

There is enough for everybody's need and not for anybody's greed.

Mahatma Gandhi blamed human beings for depletion of resources because of (ONE) over exploitation of resources (TWO) Unlimited needs of human beings. So, conservation is very important.

Resource planning And Management

Resource planning is a technique or skill of proper utilization of resources. Resource planning is necessary because

(One) Resources are limited, their planning is quite necessary so that we can use them properly and at the same time we can save them for our future generation.

(two) Resources are not only limited but also, they are unevenly distributed over the different parts of the World.

(three) It is essential for the production of resource to protect them from over exploitation.

CONSERVATION OF RESOURCES

Careful use of resources is called conservation of resources. Resources are being used at a very fast rate due to the rapid increase in population. So, natural resources are depleting fast, wisely using resources can control the depleting ratios. Development is necessary without affecting the needs of the future generations. If the present needs of resources are met and the conserving of resources for the future are balanced, we call it sustainable development.

Sustainable development can take place when

(1) The reasons of depletion are identified.
(2) Wastage and excess consumption is prevented.
(3) Reusable resources are recycled.
(4) Pollution is prevented.
(5) Environment is protected.
(6) Natural vegetation and wild life are preserved.
(7) Alternative resources are used.

The easiest way to conserve resources is to follow the '3R's. Reduce, Reuse and Recycle.

Recap

Anything that fulfills human needs can be called a resource. Resources provided directly by nature are natural resources. All living things are biotic resources. All non-living things are abiotic resources. Collection of resources directly from nature is called primary activities. Actual resources are being used at present. Potential resources are not utilized at present. After consumption, resources can be renewed with the period of time is called renewable resources. The resources which cannot be immediately renewed once they are depleted are called non-renewable resources. Resources that found everywhere are Universal resources. Resources found in specific regions are called localized resources. Natural resources when processed to meet man's needs are called man-made resources. People are also referred to as resources. Tertiary activities are those which render services to production and distribution of goods. Careful use of resources is conservation of resources. When the present population's needs are fulfilled, the future generation's needs will be met without damaging the environment, sustainable development take place.

Glossary

Manufacture production. Solar panel A plate that can absorb solar energy. PV cells Photo voltic cells Localized Limited to specific areas. Universal found everywhere. Open ocean areas of ocean that does not belong to any country. Depleting reducing. Conservation saving for future use. Sustainable able to be maintained. Tertiary third level. Do You Know?

1. Anything becomes a resource only when its use is discovered. The needs of human beings are ever changing. According to the ever changing needs, resources keep changing. Time and Technology are two important factors that determine whether a substance is a resource or not. for example: Sun's energy to generate electricity was made possible after the invention of solar panels (technology); and the receding of coal and petrol needed an inexhaustible resource (time).

2. Marine yeast have greater potential than the terrestrial yeast. They can be used in baking, brewing, wine, bio-ethanol and pharmaceutical protein production.

3. Tropical rain forests are called the 'World's largest Pharmacy' as 25% of the natural vegetation are medicinal plants. (example) Cinchona.

4. Ambergris is an extract from the sperm whale. A pound (0.454kg) of sweet – smelling ambergris is worth US $63,000 and used in perfume industries.

An example of international resource is ambergris.

4. What is the difference between man-made resources and human resources?

Answer: Man-made resources are natural resources modified or processed by technology, such as sugar processed from sugarcane and structures like bridges, houses, and roads. Human resources are groups of individuals who use nature to create more resources, such as doctors, teachers, and scientists. Man-made resources are physical objects while human resources are people with skills and knowledge.

5. Write the Gandhian thought on conservation of resources.

Answer: "There is enough for everybody's need and not for anybody's greed." Mahatma Gandhi blamed human beings for depletion of resources because of over exploitation of resources and unlimited needs of human beings. According to Gandhi, conservation is very important to prevent resource depletion.

F) Give Detailed Answers for the Following Questions (100 to 120 words)

1. How are natural resources classified? Explain any three with examples.

Answer: Natural resources can be classified into different groups depending on origin, development, renewability, distribution, and ownership. On the basis of origin, resources are classified into biotic and abiotic resources. All living resources like plants, animals and micro-organisms are biotic resources, while non-living things like land, water, air and minerals are abiotic resources. Based on renewability, resources are classified as renewable and non-renewable. Renewable resources like air, water, and sunlight can be renewed with passage of time, while non-renewable resources like coal, petroleum and natural gas cannot be immediately renewed once depleted. On the basis of distribution, resources are classified into localized and universal resources. Localized resources like minerals are present in specific regions, while universal resources like sunlight and air are present everywhere.

2. How can resources be conserved?

Answer: Careful use of resources is called conservation of resources. Resources are being used at a very fast rate due to rapid increase in population, so natural resources are depleting fast. Sustainable development can take place when the reasons of depletion are identified, wastage and excess consumption is prevented, reusable resources are recycled, pollution is prevented, environment is protected, natural vegetation and wildlife are preserved, and alternative resources are used. The easiest way to conserve resources is to follow the '3R's - Reduce, Reuse and Recycle. This helps in maintaining resources for future generations while meeting present needs without damaging the environment.

3. What is resource planning and why is it necessary?

Answer: Resource planning is a technique or skill of proper utilization of resources. Resource planning is necessary for several reasons. First, resources are limited, so their planning is quite necessary so that we can use them properly and at the same time save them for our future generation. Second, resources are not only limited but also unevenly distributed over different parts of the world. Third, it is essential for the production of resources to protect them from over exploitation. Proper resource planning ensures sustainable development and helps prevent depletion of valuable natural resources while meeting current and future needs effectively.

4. Explain the primary, secondary and tertiary activities.

Answer: Primary activities involve collection of resources directly from nature, such as hunting, food gathering, fishing, forestry, agriculture, cattle rearing, and mining. Early humans collected things through these activities to fulfill their basic needs of food, clothing and shelter. Secondary activities involve transforming raw materials into finished goods through manufacturing processes. Natural resources are modified or processed by technology into man-made resources, such as processing sugarcane to get sugar. Man's skills and ideas are basic requirements for these activities. Tertiary activities are concerned with the distribution of primary and secondary products through transport and trade systems. Examples include banking, trade and communications. These activities render services to production and distribution of goods, connecting producers with consumers.
