Question
Explain briefly the ‘rivet popper hypothesis’ of Paul Ehrlich.

Answer

Paul Ehrlich proposed Rivet popper hypothesis to show the effect of biodiversity loss on the ecosystem. An airplane (ecosystem) has thousands of rivets. Popping of rivets (causing a species to become extinct) by passenger may not affect flight safety (Proper functioning of the ecosytem) in the beginning but the plane will become dangerously weak over a period of time. Removal of a rivet of a critical part like wing (key species that derive major ecosystem functions) is obviously a more serious threat to flight safety than loss of a few rivets on the seats or window inside the plane.
