Cultures have long heard wisdom in non-human voices: Apollo, god of music, medicine and knowledge, came to Delphi in the form of a dolphin. But dolphins, which fill the oceans with blipping and chirping, and whales, which mew and caw in ultramarine jazz - a true rhapsody in blue - are hunted to the edge of silence.
Light doesn't penetrate beneath the surface of the water, so ocean creatures like whales and dolphins and even 800 species of fish communicate by sound. And a North Atlantic right whale can transmit across hundreds of miles.
We owe it to our children to be better stewards of the environment. The alternative? - a world without whales. It's too terrible to imagine.
It had an enormous impact to the point of the United Nations passing a resolution against the killing and hunting of these whales as they are an endangered species. This was a documentary on the plight of the whales.
Ten percent of the big fish still remain. There are still some blue whales. There are still some krill in Antarctica. There are a few oysters in Chesapeake Bay. Half the coral reefs are still in pretty good shape, a jeweled belt around the middle of the planet. There's still time, but not a lot, to turn things around.
Right whales, for all their size, are surprisingly athletic. They roll, they slap their flukes, they lift their heads out of the water in a move known as a spy hop. They find playthings and are particularly fond of swimming repeatedly through clumps of seaweed, which slides over them like a feathered boa.
The immense cities lie basking on the beaches of the continent like whales that have taken to the land.
I'm not someone who can lie on a beach and do nothing. I am not sure what you are supposed to do, so I get bored. I prefer to have a purpose, such as going to Alaska to see orca whales.
I am into nature and seeing whales. I went whale-watching, and I was really looking forward to that, but when you see it on TV and you see other programs do it, you're seeing close-ups of these massive creatures, and the music that's added gives you a certain feeling.
Many people cycle or swim to keep trim. But if swimming is so good for the figure, how do you explain whales?
