What does the loss of rivets on the wings of the airplane represent in the analogy?
- A minor inconvenience
- A serious threat to flight safety (correct)
- A negligible impact on the ecosystem
- An improvement in flight performance

What is the 'rivet popper hypothesis' used by Paul Ehrlich?
- A method to remove rivets from airplanes
- A strategy to strengthen ecosystems
- A theory about the extinction of species
- An analogy to explain the impact of species extinction on ecosystems (correct)
Study Notes
The Rivet Analogy
- As more and more rivets are removed from the airplane, it becomes increasingly fragile and prone to catastrophic failure.
- The loss of rivets on the wings of the airplane represents the extinction of species from an ecosystem.
The Rivet Popper Hypothesis
- The 'rivet popper hypothesis' is used by Paul Ehrlich to describe the sudden and unpredictable collapse of an ecosystem when too many species are lost.
- This hypothesis suggests that the removal of one or more key species can lead to a cascade of extinctions, ultimately resulting in the collapse of the entire ecosystem.
