Resources, , 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”., , Let’s do, List out five, resources you use, in your home and, five you use in, your classroom., , 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., , Glossary, Patent: It means, the exclusive right, over any idea or, invention.

Glossary, Technology: It is, the application of, latest knowledge, and skill in doing, or making things., , Activity, Circle those, resources from, Amma’s list that, are regarded, as having no, commercial value., , 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, “A very, newer modes of transport. The technology, valuable one!”, to create hydroelectricity, has turned energy in fast, “So I am a, flowing water into an resource too!”, important resource., , Types, , of, , Resources, , Resources are generally classified into, natural, human made and human., Amma’s List, Cotton cloth, Iron ore, Intelligence, Medicinal plants, Medical knowledge, Coal deposits, Beautiful scenery, Agricultural land, Clean environment, Old folk songs, Good weather, Resourcefulness, A good singing voice, Grandmother’s, home remedies, Affection from, friends and family, , 2, , Resources, , and, , Development, , 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 are classified into different groups, depending upon their level of development and use;, origin; stock and distribution., On the basis of their development and use resources, can be classified into two groups, actual resources and, potential resources., Actual resources are those resources whose quantity, is known. These resources are being used in the present., The rich deposits of coal in Ruhr region of Germany and, petroleum in the West Asia, the dark soils of the Deccan, plateau in Maharashtra are all actual resources., Potential resources are those whose entire quantity, may not be known and these are not being used at

present. These resources could be used in the future., The level of technology we have at present may not be, advanced enough to easily utilise these resources. The, uranium found in Ladakh is an example of potential, resource that could be used in the future. High speed, winds were a potential resource two hundred, years ago. Today they are an actual resource and, wind farms generate energy using windmills like, in Netherlands. You will find some in Nagercoil in, Tamil Nadu and on the Gujarat coast., Based on their origin, resources can be, abiotic or biotic. Abiotic resources are non-living, while biotic resources are living. Soils, rocks and, minerals are abiotic but plants and animals are, biotic resources., 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,, such resources are considered non-renewable. Coal,, petroleum and natural gas are some examples., On the basis of their distribution resources can be, ubiquitous or localised. Resources that are found, everywhere like the air we breathe, are ubiquitous., But those which are found only in certain places are, localised, like copper and iron ore., , Fig. 1.1: Windmills, , Glossary, Stock of Resource, It is the amount of, resources available, for use., , Let’s do, Think of a few, renewable resources, and mention how, their stock may get, affected by overuse., , 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., Resources, , 3

Human Made Resources, Let’s do, Make a list of, five human made, resources that you, can observe around, you., , Do you know?, Human Resource, refers to the, number (quantity), and abilities, (mental and, physical) of the, people. Though,, there are differing, views regarding, treatment of, humans as a, resource, one, cannot deny the, fact that it is the, skills of human that, help in transfering, the physical, material into a, valuable resource., , 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., “Yes,” said Raju., , Human Resources, People can make the best use of nature to create more, resources when they have the knowledge, skill and, the technology to do so. That is why human beings, are a special resource. People are human resources., Education and health help in making people a valuable, resource. Improving the quality of people’s skills so, that they are able to create more resources is known as, human resource development., “Crops ruined, due to, drought”., “Can I find, a solution?”., , that’s it!, , “…its all thanks, to the knowledge,, education and, skill… we could find, a solution…, , Read and Ponder: Humans are interdependent on, each other. Farmers provide food grains for every one., Scientists suggest various means to combat problems, related to agriculture and improve farm production., 4, , Resources, , and, , Development

Conserving 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., , Glossary, Sustainable, Development, Carefully utilising, resources so that, besides meeting, the requirements, of the present, also, takes care of future, generations., , 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.”, , Resources, , 5

“I will make sure that water is not wasted at home,”, , Some Principles of, Sustainable Development said Asha. “Every drop of water is precious”, Respect and care for all, forms of life, Improve the quality of, human life, Conserve the earth’s, vitality and diversity, Minimise the depletion, of natural resources, Change personal, attitude and practices, towards the environment, Enable communities, to care for their own, environment., , “Together we can make a difference!” chorused the, children., These are some of the things Mona, Raju and their, friends did. What about you? How are you going to help, in conserving resources?, The future of our planet and its people is linked with, our ability to maintain and preserve the life support, system that nature provides. Therefore it is our duty to, ensure that :, • all uses of renewable resources are sustainable, • the diversity of life on the earth is conserved, • the damage to natural environmental system is, minimised., , Exercises, 1.
