Great insights
And apparently, I can't disagree with any of the points
Yes, being in a hobby which is directly connected to the nature, it is our own responsibility to be vigilant about what we do and what we don't do in this hobby; not for the sake of activists but for the sake of nature.
It is just sad to see activists putting everything seem like an easy solution but simply "banning" it. I wonder how many solutions came from such groups rather than scientific findings. They always seem to pick up some broken pieces and connect the dots between those pieces according to what they want to highlight. Alongside, our side also has flaws like being tempted to buy fishes which only the most careful hobbyist can keep and lack of knowledge (yes! that's a big issue. I can confidently say that there's very few "new" hobbyist who would come over here in the first place to ask questions about what's right and what's wrong instead of going to a big box store and asking for everything that's needed to keep that nice cleaner wrasse).
In the end, what I think is the solution to sustainability is proper knowledge and being responsible hobbyist. Banning is not and never will the solution, there's always black markets for such occasions.
