Very interesting topic Eve, thanks for covering it. I agree with everything you said in the video, except for the fish tank thing. To me, this particular issue remains controversial. I am not talking about dolhpinariums and other similar facilities - these are pure evil of course. I am talking about devoted, educated and experienced fish keepers who love their fish, take good care of them and provide them with habitat that imitate their natural environment to the point where the fish might not even see and feel the difference. As a matter of fact, I discussed this thing with @valth some time ago. We are both dedicated nature lovers, we both are into aquaristics and we both seem to have a growing issue with the ethics of it, although I think I can say we are the kind of keepers that I described above. I wish some smart scientific dudes could carry out a survey to find out whether fish can be really happy in a fish tank when given everything they need and want.
