there are a lot of big issues here
mariculture and wild stock collection in some locations are extreamly important to the locals who both benifit from it and in return protect the reef which is a good thing
but unfortunetly where there is money to be made some will have no regard for nature - these are the ones obviously need to be stopped
- getting the regulations to apply to the correct people is the problem. regulation is neccessary!
supporting aquaculture is always a good thing but some wild collection is not the issue. the reefs of the world can be sustainable if we all act responsibly and take great care of those critters we place in our tanks.
the impact of pollution, over fishing, invasive species, and other human activities though is of great concern and may lead to the downfall of oceans, estuaries, reefs, and even fresh water ecosystems. this is a problem that needs immediate attention but has no immediate answer
