Passage Summary: Some people aren't worried about food because production is currently outpacing population growth. The expert disagrees, arguing that because there is a hard limit on how much food the planet can produce, we will eventually run out.

Conclusion: Widespread food shortages are bound to happen eventually.

Reasoning: The Earth has a finite limit on food production, and we can only increase current production by a small multiple before hitting that cap.

Analysis: The expert's argument relies on the assumption that human demand (population) will eventually exceed the planet's maximum possible supply. To strengthen this, we need evidence that the population will continue to grow or that the maximum production capacity is lower than previously thought. Look for an answer that suggests population growth won't stop before it hits that production ceiling. Without that link, the 'inevitability' of the shortage is just a guess.
