Natural Resources

2. Renewable and Nonrenewable Resources pg 42
All natural resources can be described as either renewable or nonrenewable
Renewable resource – a resource that can be made again by nature or by people in a practical amount of time
Nonrenewable resource – a resource that takes too long to replace or cannot be replaced at all

3. Renewable and Nonrenewable Resources pg 42

4. Renewable and Nonrenewable Resources pg 43
Sometimes renewable resources become scarce when they are overused by humans
Fresh water replaces itself through the water cycle, but if humans use too much fresh water before it can be renewed through the water cycle, then it will become scarce
Trees can also suffer from overuse and become scarce if they are not replanted after being cut down or clear-cut
Scarce – hard to find

5. Renewable and Nonrenewable Resources pg 43
When we conserve our resources we are making sure that we only use them for reasons of necessity
Examples: planting new trees to replace the ones that were cut down, using less water to allow the water cycle to recover
Conservation – the act of keep something from being lost or wasted

6. Renewable and Nonrenewable Resources pg 43
Recycling examples:
Recycling – a process designed to recover and reuse materials instead of throwing them away

7. Renewable and Nonrenewable Resources pg 43

8. Why is it important to use natural resources wisely?
(pg.43)

9. Renewable and Nonrenewable Resources pg 44-45
The best way to make our natural resources last as long as we need them is to try and find alternate resources that are underutilized
Solar, Wind, and Water are all examples of underutilized resources
We can use these natural resources to create electricity and we can stop using the fossil fuels and natural gases to conserve them
