Zoo Tigers Are Ambassadors for Dwindling Wild Population

This is what the Chinese call the Year of the Tiger, but there's not much to celebrate among those who care for the big cats. There are only about 3,000 tigers remaining in the wild, largely because Chinese people use parts from poached animals to treat minor medical problems. It's gotten to the point that when the next Year of the Tiger comes around in 12 years, there may be NO more tigers roaming the wilds. The Allegheny Front's Jennifer Szweda Jordan speaks with Pittsburgh Zoo curator Ken Kaemmerer about the disappearing tigers.
