“You should be afraid if you are in the ocean and don’t see sharks.”

There are some who would like to see the oil rigs removed right down to the ground once their job is done, and there are others, and I count myself among them, who think that once they are in place they begin to be adopted by life in the ocean as a habitat.

They have curiosity. ‘Who, what, where, why, when, and how!’ They never stop asking questions, and I never stop asking questions, just like a five year old.

I am not in any hurry to grow up.

What we once used as weapons of war, we now use as weapons against fish.

I’m not against extracting a modest amount of wildlife out of the ocean for human consumption, but I am really concerned about the large-scale industrial fishing that engages in destructive practices like trawling and longlining.

We wouldn’t be able to survive. We would have a hard time surviving if we were transported to the time when dinosaurs were around.

I’ve always said, ‘Underwater or on top, men and women are compatible.’

To lose it means that we will dismember the vital systems that make the Arctic work. It’s not just a cost to the people who live there. It’s a cost to all people everywhere.

Some experts look at global warming, increased world temperature, as the critical tipping point that is causing a crash in coral reef health around the world.

Green’ issues at last are attracting serious attention, owing to critically important links between the environment and the economy, health, and our security.

We have taken the manatees out of the areas in the Caribbean and really elsewhere in the world, and this disruption to the system makes such systems vulnerable to changes as they come by, whether it’s in terms of disease or terms or global warming for that matter.

It’s akin to using a bulldozer to catch a butterfly, destroying a whole ecosystem for the sake of a few pounds of protein. We wouldn’t do this on land, so why do it in the oceans?

Any astronaut can tell you you’ve got to do everything you can to learn about your life support system and then do everything you can to take care of it.

You don’t stand around arguing about who’s responsible, or who’s going to pay.

I love my Force Fins, which are the kind of fins Special Forces use and really are adapted from the fins of fish. They’re very efficient.

If we could magically transport ourselves back to the young Earth, when it was only a billion years old or two billion years old or three billion years old or four billion years old.

Not until we take the place of a servant can He take His place as Lord.

Focus on what you’re grateful for in your life. If you don’t appreciate what you have, you won’t get any more… because the universe thinks it’s not important to you, and therefore you don’t need any more.

I will not give to a woman a pessary to cause abortion.

Islam is itself destiny and will not suffer destiny.

May we always be possessed by the consciousness that we are not our own.

The sunlit face of the earth would appear to shine by the light diffused back into space from the land and water-covered areas.

Love may not make the world go round, but I must admit that it makes the ride worthwhile.

The knighthood I received was a fantastic honour but it’s not something I’ve ever used and I don’t think I ever will.
