3. Aim #76: How are natural resources cycled through our environment?

4. Ever wonder where we're getting all the materials for our products and packaging?
NATURE:
NATURAL RESOURCES

5. 1) Natural Resources Materials that are supplied by nature.
Go to Section:

6. 2) Group the following resources into two groups

7. 3) Renewable Resources Replaceable
Items that will keep coming back as long as we treat them properly.
Ex. when we cut down trees for paper, we can replant new trees & get more paper.

8. 4) What will happen in the future if we use our renewable resources without replacing them?
If they are not replaced as fast as they are used we will run out of them

9. Over Fishing
Section 6-2
According to the graph, fish are being caught faster than they can be replaced. Due to overpopulation.
World Fish Catch
World Fish Catch per Person
Total Catch
(million tons)
Go to Section:

10. 5) Non-Renewable Resources
Finite = limited
Can not be replenished by natural processes.
Once we use them, they're gone FOREVER.

11. 6) What will happen in the future if we keep on using our non-renewable resources?
We will run out of them because there is a finite amount of them. Once they are gone, they’re gone

12. 7) Which product should you buy?
Plastics are made from fossil fuels
Why?

13. 8) How can we prevent the depletion of our natural resources?
Remember the 3 R’s:
Reduce
Reuse
Recycle

14. 9) Recycle
This prevents new resources from having to be used.

15. 10) Reduce We need to reduce our use of natural resources.
Of course, just because paper is renewable and can be recycled, it doesn't mean we can waste it.
As important as recycling is, it still uses natural resources. The trucks that pick up and transport recycled products still use energy like fossil fuels to collect them, and fossil fuel is also needed to process (melt) the materials.
We need to reduce our use of natural resources.

16. 11) Re-use
We need to start treating the environment like a library - borrow items and bring them back no worse for the wear.

17. Summary
Can you classify these?
