I think this issue needs a little more explanation than the OP provided:
Basically, there's a rising belief among ecologists that the Giant Panda would have died out by now anyway, even without human intervention. The argument is that as a species, the Giant Panda has pretty much been fucked by evolution: it eats one type of food, lives in one climate/ geographic region, and reproduces too slowly. And by spending so much money on keeping it alive, groups are wasting money that would be
much better spent on other species, which have a greater chance, as well as its another case of 'Bambification': the trend for cute animals to get more attention by the public, regardless of their importance to the ecosystem, which is ultimately harmful to conservation efforts.
So thats the argument for letting it die of. Now, obviously, its up to individual people to read up on the issue themselves, and decide if a)they think those theories have enough evidence and b)if, regardless, it would be moral to let a species die.
Hope I helped
