Discussion Overview

The discussion revolves around the extinction of the western black rhino, exploring the causes, implications, and broader themes of species extinction and human impact on wildlife. Participants reflect on the nature of extinction, the role of poaching, and the economic factors influencing conservation efforts.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants note that the western black rhino was declared extinct due to poaching, emphasizing that this extinction was not a natural occurrence.
  • Others discuss the broader implications of extinction, suggesting that all species eventually die, including humans, and that the average lifespan of a species is roughly 1 million years.
  • A few participants express concern over the economic interests that prioritize human needs over wildlife conservation, questioning the morality of the horn and ivory trade.
  • One participant shares an anecdote about the poaching of bears for their gall bladders, drawing parallels to the poaching of rhinos and discussing shifts in market demand.
  • Some participants reflect on the interconnectedness of life and the impact of economic systems on environmental degradation, suggesting that a lack of compassion leads to a disconnection from nature.

Areas of Agreement / Disagreement

Participants express a range of views on the causes and implications of the western black rhino's extinction, with no consensus on the moral or economic considerations surrounding wildlife conservation. The discussion remains unresolved regarding the balance between human interests and the preservation of species.

Contextual Notes

Some claims about species lifespan and extinction rates are presented without detailed evidence or context, and the discussion includes various assumptions about human impact on wildlife and economic motivations.

Africa's western black rhino is now officially extinct according the latest review of animals and plants by the world's largest conservation network.
The subspecies of the black rhino -- which is classified as "critically endangered" by the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species -- was last seen in western Africa in 2006.

Sickening.
 
:frown:
 
All species eventually die (as will the human species at some point). Average lifespan for a species is approximately 1 million years (very roughly), with an average skewed by many short lived species and a few long lived species.

That said, the rate of extinction at this particular time rates as a mass extinction event. In the past, life on Earth has always recovered from mass extinctions after about 5 to 10 million years (longer than the lifespan of the Homo genus, let alone our species).

The sad thing is that it was not natural per say. It was from poaching.

Exactly, it wasn't their time to go. They are killed for their horns, the Chinese buy the poached horns and sell them ground up as an aphrodisiac.

Anecdote from a wildlife biologist acquaintance: some 20 years ago, Grizzly bears and Kodiak bears in Alaska were being heavily poached for their gall bladders, which were supposedly a cure for erectile dysfunction :rolleyes:. The main markets were Japan and South Korea.

But the poaching reduced noticeably around 2000. Why? Viagra! Unlike bear gall bladder, it *actually* works, so why go kill a poor bear?

Poaching is still a big issue, though. Apparently there is still a market for other "medical" :rolleyes: uses for bear gall bladders.

Well the Western Black Rhino is a subspecies of the Black Rhino species (still around), so by that standard a human subspecies has already gone extinct (Neanderthals).

No big deal: I place the economic interests of humans over that of rhinos (or trees, for that matter).

Are you saying you support the horn/ivory trade?

So much derp, on so many levels.

I read a book called "Uncas" it was a good book and spoke of the unification of the Mohegan Indian tribes on the east coast(CT) area. Can you imagine that time of clear waters and knowing what was coming. This person unified the tribes which enabled settling that much earlier and allowed the development of the US.

What would have happened during various wars and what would have been the outcome had this tribe not unified the coastal tribes. He questioned his acts until death wondering the affects of what he had done.

Without compassion or a sense of loss or respect for all life a human being is nothing to themselves or to anyone else. Our disconnected reality is our greatest enemy in life and will always be.

The economic system is a curse upon the Earth that drives all that has ever been bad upon this earth. We could have become what we can be without it.

Of course, everything they sell is either an aphrodisiac or grants good luck... or breaks 2 days after you buy it.
Damn iPed.
