I've been painfully aware of the threat to our oceans for a while now, but I know how badly we're killing off our diminishing shark population. 100 million sharks are killed each year, primarily for shark finning only. This has a devastating effect on the entire ecosystem in the ocean, on the scale of global warming, or worse! Not to mention the insane cruelty and wasteful hunting of these mostly harmless animals. I'd swim with a school of sharks any day (in fact, I have), but I would never consider walking with a pack of lions, or go near a grizzly.
I just finished watching the documentary Sharkwater, and if you haven't seen it yet, please watch it. It's sad, scary, and quite eye opening. We're destroying the oceans, and it's happening fast. More information about the film, and the danger to the shark populations and the oceans at [http://www.sharkwater.com/ sharkwater.com]. Please help, write about it in your blogs, tell your friends, get active! I've started a new "section" on my site, to start collecting information and links about this issue.
