Yeah, I know. It's another thing to worry about, but maybe you can actually do something about this.  Out of fear, ignorance and a love of soup, we are steadily wiping out the world's sharks.  They're not as lovable as panda bears, but sharks may be more important to our survival than almost any other creature on earth. The new film, Sharkwater opens this week in Bay Area theaters.  As coastal dwellers I think we should  know more about possible extinction of one of our neighbors below the water line.

Aside from being a stunningly beautiful nature flick, Sharkwater points the fin of blame at those responsible for the wholesale slaughter of a creature that is so perfectly evolved,  it has remained unchanged over millions of years. Hint: China and Costa Rica don't come off looking too good.
