Himself - Narrator:
Global changes now threaten the great blooms of plankton on which the whales depend. Once, not so long ago, 300,000 blue whales roamed the oceans. Now, less than 3% of that number remains. Our planet is still full of wonders. As we explore them, so we gain not only understanding, but power. It's not just the future of the whale that today lies in our hands. It's the survival of the natural world in all parts of the living planet. We can now destroy or we can cherish. The choice is ours.
