• 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:
