1. NON-RENEWABLE RESOURCES

2. Non – renewable resources
A natural resource that is available only in limited amounts
Cannot be replaced quickly by natural processes
Examples: topsoil, fossil fuels for energy
Approximate world usage of fossil fuels

3. Non-renewable resources: Mining
What is mining?
Mining is a non-renewable resource
Minerals like diamonds, aluminum, copper are taken out of the Earth
How do mining projects affect the environment and ecosystems?
Video clip: mining emeralds in Colombia
Strip mining for coal

4. Fossil Fuels Most common non-renewable resource and is used for energy
Found in 3 forms:
Coal
Oil (gasoline, fuel for planes, trucks, heating)
Natural gas
Formed when organisms die and are buried in layers of rock/soil
Under intense heat and pressure

5. Why do you think fossil fuels are non-renewable?

6. Fossil fuels: Environmental Impact
Burning fossil fuels releases chemicals and substances that contaminate the air and water
A common product made from fossil fuels (oils) is plastic
While we continue to use fossil fuels, how can we try and reduce our environmental impact?
3Rs!: Reduce, reuse and recycle

7. NUCLEAR ENERGY
Huge amounts of energy are stored in the nucleus of an atom
When this nucleus is split, the energy released is used to generate electricity
water is heated by this energy and turns to steam, which turns turbines to produce electricity
Example: uranium (U)

9. What are they worth ($$$) ?
We use fossil fuels to ‘power’ most objects in our lives:
Cars, factories, electricity for houses
Finding new sources of fossil fuels or rare metals can be very lucrative
Can make a large profit/ a lot of money
However, there are only a limited amount of these fossil fuel and rare metal reserves on the planet
