“Meat reared on land matures relatively quickly, and it takes only a few pounds of plants to produce a pound of meat.”

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

Ten percent of the big fish still remain. There are still some blue whales. There are still some krill in Antarctica.

It’s a fact of life that there will be oil spills, as long as oil is moved from place to place, but we must have provisions to deal with them, and a capability that is commensurate with the size of the oil shipments.

I would love to slip into the skin of a fish and know what it’s like to be one. They have senses that I can only dream about.

Ocean acidification – the excess carbon dioxide in the atmosphere that is turning the oceans increasingly acid.

My first encounter with the ocean was on the Jersey Shore when I was three years old and I got knocked over by a wave.

There’s something missing about how we’re informing the youngsters coming along about what matters in the world. We teach them the numbers and the letters, but we fail to communicate the importance of our connection to the living world.

Hold up a mirror and ask yourself what you are capable of doing, and what you really care about. Then take the initiative – don’t wait for someone else to ask you to act.

Protecting vital sources of renewal – unscathed marshes, healthy reefs, and deep-sea gardens – will provide hope for the future of the Gulf, and for all of us.

When I first ventured into the Gulf of Mexico in the 1950s, the sea appeared to be a blue infinity too large, too wild to be harmed by anything that people could do.

I want everybody to go jump in the ocean to see for themselves how beautiful it is, how important it is to get acquainted with fish swimming in the ocean, rather than just swimming with lemon slices and butter.

Bottom trawling is a ghastly process that brings untold damage to sea beds that support ocean life.

No water, no life. No blue, no green.

America gains most when individuals have great freedom to pursue personal goals without undue government interference.

Ice ages have come and gone. Coral reefs have persisted.

A lumberman will look at a forest and see so many board feet of lumber. I see a living city.

There are very few people on top of life, and the rest of us don’t like them very much.

Journeys are the midwives of thought. Few places are more conducive to internal conversations than moving planes, ships or trains.

Everyone wants a better life: very few of us want to be better people.

For paranoia about ‘what other people think’ : remember that only some hate, a very few love – and almost all just don’t care.

If our lives are dominated by a search for happiness, then perhaps few activities reveal as much about the dynamics of this quest – in all its ardour and paradoxes – than our travels.

So I’m one of the few celebrities that got to do a repeat performance on ‘The Simpsons,’ which I’m very flattered by.

Help one kid at a time. He’ll maybe go back and help a few more.
