• Renewable: Resources which occur in abundance and are renewed on their own by our mother nature through
          the natural process of recycling, replacement and reproduction are called renewable resources. Example: forest,
          wind, water, sunlight, etc.
           • Non-Renewable: Resources that are limited and cannot be replaced at the same speed at which they are used
          up are called non-renewable resources. It takes millions of years to form inside the earth. Examples include fossil
          fuels, minerals, natural gases, nuclear energy, etc.
           • Exhaustible: Resources which are present in limited quantity and will deplete after a few hundred years due to
          their over consumption by human activities. For example: coal, petrol, natural gas, water, etc.
           • Inexhaustible:  Resources which  are  present  in abundance  and  cannot  be  exhausted  even  by  their  over
          consumption are called inexhaustible resources. For example: air, solar energy, etc.



                      Brainy Fact


               28 July every year is celebrated as World Nature Conservation Day that focuses on conserving and
               protecting our natural resources.


                 Natural Resources Conservation


        Natural Resource is the main reason for our existence on this planet. Many natural resources are present in the
        environment in abundance, some resources can ultimately perish due to increase in population and industrialisation.
        It is important to conserve these natural resources by doing our part in saving it for our future generation. The
        direct or indirect consumption of natural resources across the globe has led to their rapid depletion; as a result of
        this many countries of the world are calling for better means of managing and sustaining these natural resources.

        Need to Conserve Our Natural Resources
        We need to conserve our natural resources because of the following reasons:
           • For our survival.
           • To maintain our environmental balance.
           • It is an important factor for the economic development of a country.
           • It takes millions of years to replenish non-renewable resources.
           • Due to increase in population and rapid urbanisation, these resources are getting exhausted at a higher rate.




                      Brainy Fact

             China has the most natural resources estimated to be worth $23 trillion: 90% of which are coal and
             rare earth metals.



        How To Conserve Our Natural Resources
        Natural Resources are consumed by living organisms directly or indirectly for their existence. Conservation of
        natural resources helps maintain an ecological balance. We can conserve it for our future generations by protecting
        it in different ways as discussed below:

        Water Conservation
        Water is an essential natural resource for the existence of life. Our body is made up of 70% of water. We need
        water for agricultural, industrial, household and recreational activities. We can conserve water by using the given
        measures:
