Actually, it's not zoos that do much of the ex-situ breeding when it comes to Giant Pandas; there are rather breeding facilities in China, like the ones in Chengdu or Wolong, where Giant Pandas are "encouraged" to reproduce in captivity-including AI and hand-rearing cubs (both quite successfully).
Due to that, I don't think there is much to worry about the future of Giant Pandas; there are species like the Javan Warty Pig or the Giant Ibis that are more needy of public interest and protection.
To give birth to several youngs but mosty rear only one successfully isn't something unheard of in nature. In various other animal species, like birds of prey or waterfowl, the "runt of the litter" dies-unless enough food is available; in some species, the "runt" might even serve as dinner for its bigger sibbling ("Cainism", observed in the case of several raptor species). This reproduction system might be considered a way of adaption to changing environments.
