I will not be going back to Nusa,while this is going on and i am sure others i know will not also.
I have deliberated this point myself. On the one hand, the locals need the tourist dollars, euros, whatever the divers bring. On the other hand, it is possible that conserving the shark population might bring more tourist dollars, but the locals may not be aware of that point, and must be educated about it. This needs to be accomplished by a local body, but I don't know whom. Is there a reputable organization in Bali that can do this? There is this group ...
BALI TOURISM BOARD
... but their contact page is "Under Construction". Also ...
Tourism in Bali – Bali tourism authority
... but are these groups actual "boards" or "authorities", or are they just advertisers? Does anyone know of an authoritative group on the island? If so, I would suggest that divers and any concerned person contact them and voice their concern. I would personally go farther than saying I won't go back to Nusa Penida; I would likely say that I won't dive Bali again. But the education must be out there to the fishing villages, and someone must see that those villages all profit from a restructuring of their lives in order to conserve the shark population, or nothing will change.
If anyone has any contacts or contact info, please let us know. There's a global subculture of people out there for whom shark conservation is of extreme importance; we can utilize them to bring more pressure to bear on this particular issue.
If just talking about this issue to someone doesn't have enough impact, share the link to the Bali Advertiser along with this ...

Hopefully this practice can be turned around to something more productive for the islanders.
