Why Fossil Fuels are Finite
Formation Process:
- Ancient organisms - Plants and marine organisms died millions of years ago
- Burial - Layers of sediment buried the organic matter
- Pressure and heat - Over millions of years, pressure and temperature converted organic matter
- Chemical transformation - Organic compounds became hydrocarbons (oil, gas) or carbon-rich coal
Why they're finite:
- The formation process takes millions of years - far longer than human civilization
- We're consuming these resources thousands of times faster than they can form
- Once burned, the carbon is released as CO₂ and cannot be easily recaptured
- Known reserves are being depleted faster than new ones are discovered
