This is the only comment I will make on this so as to not derail this thread (I apologise very much if this post in itself is doing so, I just wanted to add this), but as much as I respect the fact you’re entitled to your opinion, having been to over 300 zoos / aquaria I strongly believe that the keeping of non endangered species holds a good level of educational value. That’s not to say *all* zoos are like this, I’ve been to some certainly shoddy ones where commercial gain clearly outweighs basic husbandry and the educational aspect I’m talking about. But, take somewhere like Hamerton as a good example, they hold mainly unusual and interesting species that the general public probably havent heard of nor seen before, their entire ethos is about presenting lesser known animals to the public. Whilst granted a fair few such as the brown hyena are threatened in the wild, a lot of these species are not as vulnerable and yet still pose a great level of educational value to the public, I feel its definitely more useful being able to observe and watch them in real life as opposed to in videos / documentaries, and I’m sure you understand that a lot of families can’t afford to go and see them in the wild, so it’s certainly a good thing in my opinion, however again I do respect that you are entitled to your own
