Why should we use natural resources properly and judiciously ? Explain your views.
i) On the Basis of Origin Biotic Resources: These are obtained from biosphere and have life such as human beings, flora and fauna, fisheries, livestock etc. Abiotic Resources: All those things which are composed of non-living things are called abiotic resources.
ii) For example, rocks and metals. On the Basis of Exhaustibility Renewable Resources: The resources which can be renewed or reproduced by physical, chemical or mechanical processes are known as renewable or replenishable resources. For example, solar and wind energy, water, forests and wildlife, etc.
iii) The renewable resource may further be divided into continuous or flow. Non-Renewable Resources: These occur over a very long geological time. Minerals and fossil fuels are examples of such resources. These resources take millions of years in their formation. Some of the resources like metals are recyclable and some like fossil fuels cannot be recycled and get exhausted with their use.
