Scarcity in Economics for Fossil Fuels

Steps:

• Define scarcity: Limited resources relative to unlimited human wants, forcing choices.
• Apply to fossil fuels: They are finite natural resources formed over millions of years.
• Assess supply: Extraction rates cannot keep pace with growing global demand.
• Evaluate options: Identify which directly explains insufficient supply meeting demand.

Why B is correct:

• Scarcity, per economic definition, occurs when supply is insufficient to meet demand, as fossil fuels are non-renewable and depleting reserves create this imbalance.

Why the others are wrong:

• A: Price fluctuations affect demand but do not define scarcity itself.
• C: Pollution restrictions address environmental harm, not the core resource limitation.
• D: Replacement by renewables responds to scarcity but does not cause it.

Final answer: B
