  3. 3. DEFINITION:A resource which meets the needs of humanswhich is obtained from nature is called as naturalresource.These are classified into biotic & abiotic resources.BIOTIC RESOURCES:These are living resources which are replenished.EX: plants ,animals , forest etc
  4. 4. ABIOTIC RESOURCES:These are non living resources which are not ableto replenish themselves.EX: minerals , petrol, land etc.
  5. 5. Every individual has responsibility to usenatural resources judiciously. This will giveequal opportunity to all to use the resourcesfor the benefit of mankind. One should notbe selfish to spend the available resourceswithout thinking of other fellow beings.There is no limit to spend natural resourcesif available plenty but at the same time oneshould realize that natural resources arenon-renewable sources. The future alsodepends on such resources. Every individual
  6. 6. should think himself or herself as a worldthink himself or himself as a world citizen.The whole world is a family and all are inter-dependant for a better life. The motherearth has given enough for all to satisfyminimum wants but not enough to utilize.Every individual has a role in theconservation of natural resource like inusing water electricity woods, foods etc.water is life and every drop is precious
  7. 7. similarly every chemical power saved is likeit is produced. Woods should be used so hasnot to destroy the forest procurement ofmore food than needed is like putting otherstarving. Equitable use of resources forsustainable life styles.Everyone has the right to live in this world.All living creatures belong to mother earthand they all have their shine of resourcesavailable. All these resources likeland, energy, food, mineral, water, forest etc.have to be distributed in an equitable way
  8. 8. sustainable lifestyles of all creatures. Theresponsibility lies more on the humanpopulation because they have got thethinking power and the wisdom to judgegood and had man should realize thathe is not alone in this world. Henceresponsibility should be for all human beingfor an equitable use of natural resources forsustainable use of natural resources forsustainable life styles of all in this motherearth.
  9. 9. CLASSIFICATION OF NATURAL RESOURCES BASED ON THEIR AVAILABILITY: Natural resources are classified into two types. They are (1)Renewable resources and (2)Non renewable resources. Renewable resources: Renewable resources are resources that can be produced naturally1)The resources that can be renewed by reproduction are called renewable resources.
  10. 10. 2) Renewable resources are inexhaustible.3) Renewable resources are not affected by thehuman activities.4) All biotic resources are renewable.5) For example: air and water.
  11. 11. Non Renewable resources:1)The resources that are present in fixed quantities arecalled non-renewable resources.2) Non-renewable resources are inexhaustible.3) Non renewable resources are affected by humanactivities.4) Some abiotic resources are non-renewable.5) For example- fossil fuels and minerals
  12. 12. AFFORESTATION: Afforestation is the establishment of a forest or stand of trees in an area where there was no forest. Afforestation is the reestablishment of forest cover, either naturally (by natural.
  13. 13. seeding, or root suckers) or artificially (by directseeding or planting). Many governments and non-governmental organizations directly engage inprograms of afforestation to create forests andbiodiversity. In some places, forests need help toreestablish themselves because of environmentalfactors. For example, in arid zones, once forestcover is destroyed, the land may dry and become
  14. 14. inhospitable to new tree growth. Other factors includeovergrazing by livestock, especially animals such asgoats, cows, and over -harvesting of forest resources. Together these may lead to desertification and the loss of topsoil; without soil, forests
  15. 15. cannot grow until the long process of soil creation hasbeen completed - if erosionallows this. In some tropical areas, forest cover removal may result in sealing off the soil where water doesn’t penetrates into the soil and there wont be root growth.
