There are lots of beautiful places left in the world, but eventually they will get ruined by tourism and corruption of the resources these places have. Hopefully Prince William Sound will remain spectacularly beautiful simply because of the inhospitable weather and difficult access.
That is why we have national parks and comparable preserves. Competently planned and administered (key phrase), they withstand the ravages of unbridled tourism quite well. Difficult access helps a lot, as well.
