● We don’t know how these attributes are linked to species richness in a `color{violet}("community")`, but `color{brown}("David Tilman’s")` long-term ecosystem experiments using outdoor plots provide some tentative answers.
● `color{violet}("Tilman")` found that plots with more species showed less `color{violet}("year-to-year variation")` in `color{violet}("total biomass.")`
● He also showed that in his experiments, `color{violet}("increased diversity contributed")` to higher productivity.
● Although, we may not understand completely how species `color{violet}("richness contributes")` to the well-being of an `color{violet}("ecosystem,")` we know enough to realize that `color{violet}("rich biodiversity")` is not only essential for `color{violet}("ecosystem health")` but imperative for the very survival of the human race on this `color{violet}("planet.")`
● At a time when we are losing species at an alarming pace, one might ask–
`star` Does it `color{violet}("really matter")` to us if a few species become extinct?
`star` Would `color{violet}("Western Ghats ecosystems")` be less functional if one of its tree frog species is lost forever?
`star` How is our quality of `color{violet}("life affected")` if, say, instead of `color{violet}("20,000 ")` we have only `color{violet}("15,000")` species of ants on earth?
● There are no direct answers to such näive questions but we can develop a proper perspective through an analogy the (`color{brown}(" ‘rivet popper hypothesis’")` ) used by Stanford ecologist `color{brown}("Paul Ehrlich.")`
● In an `color{violet}("airplane (ecosystem)")` all parts are joined together using thousands of rivets (species).
● 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 (`color{violet}("proper functioning of the ecosystem")`) initially, but as more and more rivets are removed, the plane becomes dangerously weak over a period of time.
● Furthermore, which `color{violet}("rivet is removed")` may also be critical.
● Loss of rivets on the wings (`color{violet}("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.
