Facts that Matter

  • Any substance, living being or service that has utility (i.e. can help us in any possible way) is said to be a resource.
  • A resource has some value. The value can be associated with money (i.e. you have to pay money to get it), or just mental satisfaction (e.g. when you look at a beautiful painting or scenery, it feels pleasant, so the painting or scenery has utility).
  • Examples of resources include books, stationery material, clothes, utensils, furniture, your teacher, school, rivers, water, electricity, and so on.
  • The economic value of a resource may change with time.
  • A substance may or may not be a resource depending on our knowledge. If we do not know how to write with a pen, then certainly the pen has no utility for us. So in this case the pen is not a resource. However, for those who know how to use a pen, it is a resource. So technology, ideas, knowledge, inventions, discoveries, etc. make a substance a resource.
  • Time may also be a factor involved in making a substance a resource. Water has always been there, but its utility to manufacture electricity was not always known. When people realised that water can be used to produce electricity, water became a resource in a new way.
  • Resources may be natural, human, or human-made.
  • Natural resources are those that are taken from nature. They are used without modifying them, i.e. in the same form as they exist in. Rivers, lakes, air, soils, minerals, trees, mountains, etc. are natural resources.
  • On the basis of level of development of resource, a natural resource can be actual or potential. An actual resource is one which is used currently. We know their quantity. Examples are: coal deposits. A potential resource is one whose utility is not known at present or is not used despite having utility; instead it may be useful at some time in future. It means that it has the potential to have utility, although it does not have any today. Examples include uranium deposits in Ladakh.
  • On the basis of origin, a resource can be abiotic or biotic. A biotic resource is one that has life. Examples: plants and animals. An abiotic resource is non-living. Examples: soils, rocks, furniture, books.
  • Natural resources may also be classified as renewable and non-renewable. A renewable resource can be used without any risk of its ending up. They exist in unlimited quantity, for example solar energy and wind energy. On the other hand, use of non-renewable resources need to be controlled since once they end up, they cannot be renewed. Examples: coal, petroleum.
  • On the basis of distribution, a resource can be ubiquitous or localised. A ubiquitous resource is found everywhere, like air. A localised resource is, however, found in certain parts of the world only, like we cannot find coal everywhere.
  • Human made resources have not been provided to us by nature. Human beings have used their intelligence to manufacture them for their own use. Examples include vehicles, buildings, roads, telephone, etc.
  • Human resources include people who serve us in any way. Your teacher, doctor, carpenter, cobbler, etc. are human resources.
  • Human resource development refers to the improvement of people’s skills so that they become more useful than before and are a better resource.
  • Resource conservation is the concept of using resources carefully so that they do not end up quickly. The future generations also need the resources, but if we keep using them at a fast pace, they may end up, thus posing problems for the future. We should use resources in such a balanced way that we satisfy our needs as well as conserve them for future. This concept is called sustainable development.
  • We can contribute to sustainable development by switching off lights when not needed, by recycling things and using them again, and in many more ways.
