Is it enough?

[youtube=http://www.youtube.com/watch?v=fWrgmT_Vl7Q&feature=player_embedded] I know I just posted, but this ad is worth watching.  I think it is well, done, it's tie in to images that are in the public consciousness is very effective, it doesn't take time to over explain its premise, it has some nice detail (the scrubbing of the hands and watch), and it has an element of the unexpected.

The spot does a good job of brining attention to the issue of Climate Legislation, though I'm not sure if actually makes a good case for why we need that legislation.  Is invoking images of oil covered animals enough?
