While Steem is a great platform, I don't think that your proposal is a viable use case.
First of all, reward pool is to distribute rewards among authors that produce original, high quality content.
I don't believe that many whalers can do that. And if they can, then they will be rewarded for their content, not because they are nice enough to stop killing whales.

Stating "for preserve national identity and culture" as a reason for killing whales is enough to think that it would not work. Tricky part here is, that if it would... then they are lying anyway and their reasoning is not valid.
