6. What are the two types of natural
resources?

7. Renewable Natural Resources
Nonrenewable Natural

8. Renewable Natural Resources
They are called renewable because they
can grow again and never run out.
Examples are water, wind, wood, sun and
energy wave.

9. Nonrenewable Natural Resources
These are things that can run out or be
used up which means that there is only a
limited supply or available only in limited
amount. They usually come from the
ground. Examples are fossil fuels such
as gas, oil, minerals and coal.

10. Here are examples of sustainable way of using the
natural resources:
1. Using fishnet with little holes when fishing.
2. Reducing, reusing, and recycling of materials
to lessen or cut back the amount of raw materials.
3. Using electricity generated from solar panels
instead of using electricity generated from fossil
fuels.

14. Sustainable use of
resources occurs when
the rate of consumption
can continue forever
without damaging the
environment.

15. What are other sustainable ways of using
the natural resources that are helpful in the
crisis that we are facing now?

17. How can people conserve natural
resources?

18. Why is it important to conserve natural
resources?

19. The lives of future generations depend
