Know we have choices whether to use a technological advance to obtain resources from Earth’s spheres or not.
Resource Management
Resource Management
Many of the resources we use are non-renewable. Even some renewable resources, such as trees, might be used quicker than they can regrow, so it is important for us to manage our resources and conserve what we have.
The three Rs (reduce, reuse, recycle) describe the ways in which we can conserve and manage non-renewable resources.
‘Reduce’ refers to using less materials.
‘Reuse’ means using something again rather than throwing it out.
‘Recycle’ means changing a material into another useable form.
There are many considerations to the use of a particular resource. These include:
Renewable or non-renewable?
Sustainable or not?
Importance of resource and/or use for that resource
Supply of the resource
Demand for the resource
Whether the resource can be reused or recycled
Natural resources may be living or non-living. Their value may be tangible, such as the price of an ounce of gold, or intangible, like the psychological value of being able to visit pristine natural areas. Some natural resources must be used and used wisely, but some must be preserved to maintain their value.
We use natural resources for many things. Natural resources give us food, water, recreation, energy, building materials, and luxury items.
Many resources vary in their availability throughout the world. Some are rare, difficult to get, or in short supply.
Natural resources must be preserved and protected from pollution and overuse.
Buying fewer new products and recycling will help to conserve resources.
Conserving Natural Resources
Conserving Natural Resources
So that people in developed nations maintain a good lifestyle and people in developing nations have the ability to improve their lifestyles, natural resources must be conserved and protected. People are researching ways to find renewable alternatives to non-renewable resources. Here is a checklist of ways to conserve resources:
Recycling can help conserve natural resources.
Buy less stuff (use items as long as you can, and ask yourself if you really need something new).
Reduce excess packaging (drink tap water instead of water from plastic bottles).
Recycle materials such as metal cans, old cell phones, and plastic bottles.
Purchase products made from recycled materials.
Reduce pollution so that resources are maintained.
Prevent soil erosion.
Plant new trees to replace those that are cut down.
Drive cars less, take public transportation, bicycle, or walk.
Conserve energy at home (turn out lights when they are not needed).
Questions
Questions
Identify examples of recycling and the products made from these recycled resources.

Justify the use of of coal mining or fracking. In your answer include how different groups benefit or are harmed by the use of these resources. (the farmer, mining company, parents, local business owners, environmental groups, state governments)
Discuss the importance of not upsetting the balance of nature by human activities. (Use examples of renewable resources)
List five general things we get from natural resources.
Are forests a renewable resource? Are they ordinarily used in a renewable way? How can forests be used more sustainably?
Of what value are forests besides for wood? Is there a value to forests that is not a monetary value? How much is that value considered when forests are being used for their resources?
How are fish and other wildlife renewable resources? How are they nonrenewable resources?
What is overconsumption? How does overconsumption mirror overpopulation?
If a product is recycled, is anything lost in terms of material or energy?
