I can't edit this anymore but another thing to point out about the link above is that one of the subpages contains care manuals for several types of popular animals and the statuses of other care manuals in AZA's pipeline that are being reviewed for publication.

These manuals are INSANELY detailed. There is absolutely no question that the keepers who helped create these manuals genuinely care about the animals they tend to. (Some of the manuals specify how large exhibits should be depending on whether the animals are staying on exhibit for a while or are preparing for a transition back into the wild!)

Folks that are on engineering organizations (like IEEE) or working groups (like the Kubernetes or Bluetooth SIGs) might appreciate the nuances here!

I also learned that zoologists from Disney's Animal Kingdom are HUGE contributors to these manuals and that Walt Disney himself was key in inspiring zoos to shift away from entertainment and towards conservation!
