What's In In the previous lesson, you learned that natural resources are the things that we harness from the environment to supply our needs. You also learned that these natural resources can be renewable or those that can be replenished easily after being used or nonrenewable or those that take a very long time to be replaced once consumed.



Examine the pictures in Figure 3. Which of these materials are renewable? Nonrenewable?



Because we don't have an unlimited supply of these resources, it is necessary that we use these resources in a manner that we allow them to recover and keep in abundant supply. We should make sure that the earth's resources. not consumed completely or destroyed. How can you help protect and conserve the natural resources of the earth?​
