Taking a moment here to look back a few hundred million years ago into the world of sharks.
It's ironic that we humans, who have only been around a few hundred thousand years, have evolved the ability to to recreate the ancient world of sharks to a high degree of probability. With the advent of television we can now show future generations of humans what ancient sharks once looked like (see video).
Meanwhile we're rapidly destroying the ancient sharks evolutionary prodigy, our modern sharks, in a manner that might well see a total worldwide reduction of 60% by 2020.
Take a moment and think about that one.
