The veterinarian’s role in conservation it’s his responsibility to keep the animals healthy, to advise the curatorial staff on breeding, if it’s a captive breeding situation, or on keeping animals from breeding, which is now become a big problem with zoos. So he’s gotta advise on maintaining the collection, whether it’s a breeding collection, or just an exhibit collection. He’s gotta be able to advise on that, besides treating the animals when they get sick or injured. What would you say is the largest professional problem facing US zoos today, from where you sit.
