People travel and hunt on the sea ice - in Alaska, they hunt in skin boats for bowhead whales; in Greenland, they hunt with dogsleds. The ice is their highway. The ice is also the ecosystem in which marine mammals and terrestrial animals such as polar bears exist.

I have a tattoo on my foot that says 'it's a whale' in Japanese, because Japanese people kill whales. My stuffed whale was like most children's teddy bear. I took it with me everywhere. I slept with it. I couldn't live without my whale.

Our planet is dying. Whales will be extinct before we ever get to know them. They say these creatures are so intelligent. They may disappear from the face of the Earth before we know them, and that is a great tragedy.

It's time to end the cruel slaughter of whales and leave these magnificent creatures alone.

Ships are expendable; the whales are not.

I've been diving for about 30 years, and I can honestly say that I've had some amazing encounters with sharks, squids, and other whales. But the encounter with the right whales in the Auckland Islands was probably the best thing I've ever done. It was just that amazing.

Whales are killed today to supply the limited demand for whale meat or to be used in pet foods or as fodder for fur-bearing animals used in the fur trade.

My clients are the whales and the seals.

Not only have I made films about the subject, but I've largely funded them on my own, so I'm fully committed to doing whatever I can to change the audience's respect and appreciation for the ocean. In 100 years I want whales, dolphins and sharks to still be around, and the ocean to be a healthier place.

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.

Well, this week for example, I was just in Los Angeles making a documentary for German television on whales. They had tried to get me in England where they missed me.

They are a fairly aggressive conservation organization that was started to protect the great whales particularly, but in general all marine life around the world. So those are the people I'm trying to attach my name to.

The immense cities lie basking on the beaches of the continent like whales that have taken to the land.

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.

Sea World's killer whale collection needs constant replenishing. The average life span of the animals in captivity is less than half the average for killer whales in the ocean.

Good clothes are good clothes, and they don't need whales and tricks and too many jokes. Sometimes you just need something to wear.

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.

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.

I have never suffered under any delusion that saving the whales in the Antarctic sanctuary would be easy, but the one thing I am certain of is that I and my passionate crew of international volunteers will never quit defending life in the seas from poachers, no matter what consequences we must endure to do so.

I'm concerned about the ocean and the environment. And I love whales.
