It looks like Damian is discussion deaf and just returned to the same nonsense of 'handful of species' after been shown to be wrong.
Carl: your article has weaknesses in reasoning which come up again in discussion about zoos. My comment:
- Value of tropical zoos and semi-captive breeding centers was NEVER evaluated large scale in the same way as Western zoos. All we hear are one-off examples of good tropical centers (often just starting) and one-off bad zoos. In fact, in tropics successes are few, these places often fail from the same problems as wild populations nearby (especially poor governance and uncertain funding). Most rely directly on Western zoos for expertise in wild animal husbandry and funding. Many so-called sanctuaries are venues aimed at foreign tourists with no real conservation action - a direct counterpart of the worst entertainment-based menageries.
- Every single endangered species which is saved is an achievement. it is false reasoning not to save anything, because zoos cannot save all.
- Many groups of species thrive and breed well in zoos and contain more species than zoos have physical space to keep. Therefore that many other groups do poorly in zoos is not an issue for zoos in general. Zoos can either not keep them or carefully figure out their requirements. Zoos can keep great apes, big cats, bears and bottlenose dolphins, and largely avoid red colobuses, lagomorphs, roe deer, colugos, big whales etc.
- Saving species in the wild is ALSO more often failure than not, and often turns impossible (animals go extinct).Most rare species in the wild have decreasing populations and most reserves are poorly or not at all managed and lose rare species. Anti-zoo people generally ignore it and judge zoos to higher standards and national parks to lower standards. I once said that it is possible to call two Asian reserves where whole population of rhinos was killed for one individual Sumatran rhinoceros which died without breeding in a Western zoo.
- Improving conservation in the wild is not simply the matter of moving more funds to the wild. In this way, billions were wasted over decades by putting them in national parks and generally in failed development aid. Issues like civil unrest, poor governance, invasive species, bad political decisions in the tropics are common and cannot be solved with conservation money or wished away.
- Money generated by zoos towards wild conservation come from money spend by city people on entertainment. It is well known that it cannot be taken directly to tropical conservation, but this argument is tried or implied ad nauseam.
