It start with the top. In Japan, the zoo directorship is just another municipal department head position. And they’ll put someone with absolutely no idea about biology or zoos. A guy who can’t tell a moose from a mouse into the zoo directorship. Just for two, three years. Another, shouldn’t say idiot, but another idiot comes in, so then the technical part will rely on the middle level management. Well, that is also a non-professional. The zoo professionals at that time, in the 70s in Japan, was barely maintained by keepers to use the slang, shit cleaners.
