2. Natural Resources

3. Natural Resources Resources – things that people need to live
Examples: food, potable (drinkable) water, clean air to breathe
Natural Resources – resources the Earth provides

4. Natural Resources
Most organisms adapt (change) in order to survive in their environments
Example: turtles live near ponds in order to eat aquatic plants and insects

5. Natural Resources
Other organisms alter their environment to better meet their needs
Example: beaver dams
They now have shelter, but they killed trees (killed other organisms and robbed other animals of their habitats) in order to do so

6. Natural Resources
Humans have the best ability to alter our environments, so we also make the greatest impact on Earth’s natural resources

7. Renewable Resources
Renewable Resources – natural resources that can be used indefinitely without reducing the available supply
Conservation – protecting resources to ensure they can continue to be used
Sustainable yield – the replacement of renewable resources at the same rate they are used

8. Sustainable Yield
You have a pond in your backyard and like to go fishing.
What happens if you catch all the fish in your pond?

9. Sustainable Yield What would be a better solution?
(that’s sustainable yield)

10. Renewable Resource Examples:
Surface water and groundwater, renewed through the water cycle
Soil, which is renewed every few hundred years

11. Renewable Resource Examples:
Certain elements like nitrogen, carbon, and phosphorus (all found in living things)
Certain types of energy like solar and wind energies (Sun is going to shine every day without running out)

12. Renewable Resource Examples:
Plants and animals because they reproduce and renew the population
What are some ways people use plants and animals?

13. Nonrenewable Resources
Nonrenewable Resources – natural resources that take hundreds of millions of years to replace
Exhausted supply – using resources at a higher rate than they can reform

14. (that’s exhausted supply)
You own a lumber company and need to cut down trees to sell.
What happens if you cut down all of your trees?
(that’s exhausted supply)

15. Nonrenewable Resource Examples:
Fossil fuels – fuels such as coal, oil, and natural gas that come from decomposed fossils
Gemstones (like diamonds) and precious metals like gold, silver, and copper

16. Renewable or Nonrenewable?

17. Global Resources
How does the limited supply of these products affect the market?
Natural resources are unevenly distributed around the world (so there are the haves and the have nots)

18. Global Resources
Example: Oil (oil-producing countries are some of the richest in the world)
Uneven resource distribution can lead to political tension, including wars and conflicts

19. Global Resources Example: Conflict Diamonds (aka, Blood Diamonds)
Diamonds mined in war zones and sold to finance war efforts
Often in countries experiencing civil wars, such as Angola, Ivory Coast, Sierra Leone, and Liberia

20. Global Resources
Ecological footprint (carbon footprint)- the amount of resources required to support your lifestyle
Can be calculated per person or per country

21. Global Resources
The U.S. consumes 30% of Earth’s mineral and energy resources despite having only 6% of the world’s population

22. Global Resources
According to the graphic, if everyone on Earth lived like the US, we would need ___ planets’ worth of resources to sustain life.
4.8

23. Chocolate Chip Mining

24. How are population and resources related?
1s (deer) – line up by Stns 1-5
2s, 3s, 4s (resources) – line up by Stns 6-10
Deer will walk over and get the resource they need. They are able to survive and reproduce, so they make a new generation of deer (the resource becomes a deer). Return to Stns 1-5
Deer that are unable to find a resource die, decompose, and end up being recycled into a resource (stay at Stns 6-10)

27. Progress Reports
Look through, paying close attention to missing assignments
All missing work can be turned in for credit
“Must be made up by ___” – if it’s past that date, you can still turn it in/make it up for reduced credit
Extended absences will be taken into account
Turn in signed progress reports tomorrow!
