State ten reasons why natura resources are dynamic cultural concepts

1. Water  -  one of the most important natural resources for the existence of life. Fresh water is consider a renewable resource, but most of the water humans drink comes from ground water sources that are being depleted faster than they can be replenished.

2. Helium- helium is necessary as a cooling medium for the Large Hadron Collider (LHC), superconducting magnets in MRI scanners and NMR spectrometers, and satellite instruments.

3. Bauxite - Bauxite is the main ingredient in making aluminum metal, and nearly all aluminum produced has been extracted from bauxite. It is also used in hydraulic fracturing, a process in drilling for oil and gas.

4. Natural Gas -energy needs and is used as an energy source for heating, cooking, and generation of electricity. It is also used in the process of making plastics and other commercially important organic compounds.

5. Coal-In today’s society coal has become the primary source of fuel for electricity production because it is abundant, has high energy output, and is relatively inexpensive.

6. Oil - Oil supplies 40% of the nation’s energy needs and is used for the production of gasoline, diesel fuel, jet fuel, propane, and asphalt. Oil is also used in the manufacturing of petrochemicals for production of plastics, synthetic rubber, and chemicals.

7. Salt-  known as sodium chloride, is an essential mineral for the life of humans and animals.

8. Timber -Timber is an important renewable natural resource in many societies around the world. If production is approached in a responsible way it can be both sustainable and economical.

9. Soil -oil is one of the most important natural resources on Earth, being required both directly and indirectly for food production, manufacturing of industrial raw materials, and for generation of energy sources. Soil is essential for the function of ecosystems providing nutrients, oxygen, water, and heat.

10. Iron - Iron is in everyday items all around us and is the world’s most commonly used metal. Iron is a good conductor, durable, and plentiful making up 5% of the Earth’s crust. This is why it is used to make steel, electrical wiring and conduct, pipes, tools, hinges, door handles, stoves, pots and pans, and even sofa frames.
