Giant pandas are really fascinating animals, honestly. Highly unusual and divergent in their family to the point that they were considered either procyonids or just lone oddballs in the Carnivora. They're inherently striking in appearance, not just the interesting markings but the unique shapes and forms of their faces, those strange cat-like slit pupils, and their odd "thumbs". They're so unlike any other bear. And carnivorans that revert to a more vegetarian diet like them, kinkajous and maned wolves are fascinating to me.
Their mass popularity is highly understandable, as well. But, at least from the standpoint of a zoogoer, sometimes it can feel like they overstay their welcome. Living right next to Atlanta I've seen them regularly for much of my life. They do get a little old after a while. They definitely don't 'do much'. Most likely one look into their enclosure won't be too different from the last. In my case, it rarely ever has been. Sometimes one is in the outside portion rather than indoors but that's the extent of that variation. And the nearby (fairly large) gift shop dedicated entirely to panda merchandise speaks volumes. Neither popularity nor activity levels in front of zoo visitors should be considered a prerequisite for a species' value, of course. I've tried to appreciate them a little more, myself. Even watching them chow down on bamboo it's easy to marvel at the sheer strength of their jaws and the well-adapted morphology of their grasping paws
But on the ecological end, yes, they're super niche, to their misfortune. The opposite of the generalist, adaptable brown and American black bears. Other threatened species share their habitat, though. Maybe they don't impact those other species as much as others might (although that professor discounting the profound effect elephants and wolves have on ecosystems puzzled me. Who is that guy anyway?) but I do believe they can be extremely powerful ambassadors for that region. This is why ambassador species are important, something else the professor discounted. Most people will inherently gravitate towards certain, more typically charismatic species. That's just the way it is. We can draw attention to amphibians and beetles all we want but large carnivorans, cetaceans, elephants, apes and sea turtles will remain favorites. If this is the case, conservationists do and should continue to use this to their advantage to gain support in defending the ecosystems those animals share with countless others, right down to the tiniest invertebrates.
That said - I definitely agree that less could be spent on the pandas' survival in particular, over protecting their habitat instead. Pandas aren't actually doing as bad in the wild now, comparatively speaking, are they? They're Vulnerable, no longer Endangered (something else the video botched). Their wild population is around 1,500 and reportedly on the rise. Not a bad shift from 30 years or so ago. But they likely will be Endangered again, soon, along with many, many other taxa if attention isn't continued to be given to their habitats. On the other hand, it could be argued that enough suitable land remaining for their long-term survival, regardless of efforts made, is questionable.
So despite this unexpectedly long post I'm torn. They could be considered overrated but they have value, not just intrinsically but to huge amounts of people, that can be channeled into saving many species at once. I think it's worth at least trying to drive more funds to protected land than the captive breeding, capitalizing on Ailuropoda melanoleuca's fame in a different way.
