Zoos are becoming facsimiles - or perhaps caricatures - of how animals once were in their natural habitat. If the right policies toward nature were pursued, we would need no zoos at all.
I've got two old Volvos, two old Subarus, and an old Ford Ranger. If you've got an old car, you've gotta have at least several old cars, 'cause one's always gonna be in the garage.
