Who gave rivet popper hypothesis?
Answers
Answer:
(i) Rivet-popper hypothesis was proposed by Stanford ecologist Paul Ehrlich.
It explains importance of species richness through an analogy.
(ii) In an airplane (ecosystem) all parts are joined together using thousands of rivets (species).
(iii) If every passenger travelling in it starts popping a rivet to take home (causing a species to become extinct), it may not affect flight safety (proper functioning of the ecosystem) initially.
(iv) But as more and more rivets are removed the plane becomes dangerously weak over a period of time.
(v) Further more, which rivet is removed may also be critical. Loss of rivets on the wings (key species that drive major ecosystem functions) is obviously a more serious threat to flight safety than loss of a few rivets on the seats or windows inside the plane.
