Received from AvaazPosted: 15 October 2012
Within days, governments could begin turning wide stretches of the Antarctic ocean into the world’s largest marine sanctuary, saving the habitat of whales, penguins, and thousands of other polar species from industrial fishing fleets. But they won’t act unless we speak out now. 
Most countries support the sanctuary, but Russia, South Korea and a few others are threatening to vote it down so they can plunder these seas now that others have been fished to death. This week, a small group of negotiators will meet behind closed doors to make a decision. A massive people-powered surge could break open the talks, isolate those attempting to block the sanctuary, and secure a deal to protect over 6 million square kilometers of the precious Antarctic ocean.The whales and penguins can’t speak for themselves, so it’s up to us to defend them. Let’s change negotiators’ minds with a massive wave of public pressure – Avaaz will surround the meeting with hard-hitting ads, and together we’ll deliver our message to delegates via a deafening cry on social networks.

The photo above shows a huge, ebony colored tooth of an ancient Cenozoic Era shark known as a megalodon. On top of it are two teeth from a modern era great white shark found on a California beach. Fossils indicate that megalodons reached a length of 52 ft (16 m); this compares to a length of 20 ft (6 m) for an exceptional great white shark. A shark’s tooth is one of the most commonly found fossils since sharks go through several sets of teeth during their life. Their teeth are lost routinely but new ones constantly grow in to replace the ones that are surrendered.

The great white sharks below were photographed when I went on a cage-diving expedition off Guadalupe Island, Mexico. I was on deck and not in the cage while these shots were taken. The sharks were ravenously feeding on tuna.

Below, the remains of a whale washed ashore at Ocean Beach in San Francisco in September 2010 show bite marks left by great white sharks. Though the species of whale couldn’t be identified, it was easy to tell that the bite marks were from a great white. A 2008 study determined that a great white shark specimen 20 ft (6 m) in length could exert a bite force of over 4,000 lbf (18,000 newtons), more than enough to cut through bone but not as forceful as the bite of a tiger shark or that of a Nile crocodile.

Some people think this big guy is still around….Not sure about that but the Megalodon must have had some very clean water to swim around in back then…
