CONSERVATION OF NATURAL
RESOURCES
• We know that coal and petroleum
are formed over a period of
thousands of years.
• Coal and petroleum are good
sources of energy and it is
important to conserve them
because they cannot be replenished
quickly.
• If we want to continue to enjoy the
benefits of these resources, we
must conserve them.
• All our machines such as cars and
other vehicles should be in good
working condition. This prevents
the wastage of petrol and diesel.
