Question

Who proposed the rivet popper hypothesis? Explain the same with reference to ecosystem.

Answer 1

This hypothesis was proposed by Paul Ehrlich.

• In an airplanes (ecosystems), all parts are joined together by using thousands of rivets (species).
• If every passenger travelling in this ecosystems causes the extinction of atleast one species (starts popping a rivet to take home), it may not be safer but if more and more rivets are removed, the plane becomes dangerously weak over a period of time.
• Further which rivet is removed may also be critical, loss of those on the wings is obviously a series threat to flight safety than those of a few on the seats or windows. 
• Similarly, loss of key species, which run the ecosystem properly, is obviously a more serious threat to the ecosystem than other species.
