This thread is alive for sure. Do/think whatever make you happy yourself, the rest will fall into place. Bet you if any structural regulation happened it would happen slow and the first changes seemed positive at least, but if it did drastically change I bet you 3/4 of the ppl posting would break the rules anyway. Like I said, do whatever makes you happy and let others do the same, if Peta wanna protest let em protest, i think in the end they're gonna make themselves look stupid anyway. Meanwhile there are new successes in aquarium keeping every month, people are rendered speechless at some of the fish people keep, setups they build, the quantity and size of things, breeding, etc.
Fact of the matter is people pay to see animals: zoos, safaris, charters, aquariums, documentaries, animal shows, marineland... then factor in Petsmart, Petco, the little guys, the importers, the culture in some places... Too much money for this to ever go under, at least not in our lifetimes.
