Quotations with a citation

The ocean is, in effect, our life-support system, driving climate and weather, governing the water cycle, stabilizing temperature, generating most of the oxygen in the atmosphere, taking up much of the carbon dioxide, shaping planetary chemistry. If the ocean is in trouble, so are we.

I want to get out in the water. I wanted to see fish, real fish, not fish in a laboratory.

Just as we have the power to harm the ocean, we have the power to put in place policies and modify our own behavior in ways that would be an insurance policy for the future of the sea, for the creatures there, and for us, protecting special critical areas in the ocean.

The next time you dine on sushi -- or sashimi, or swordfish steak, or shrimp cocktail, whatever wildlife you happen to enjoy from the ocean -- think of the real cost. For every pound that goes to market, more than 10 pounds, even 100 pounds, may be thrown away as bycatch. This is the consequence of not knowing that there are limits to what we can take out of the sea.

I hope Jill Tarter's wish to engage Earthlings includes dolphins and whales and other sea creatures in this quest to find intelligent life elsewhere in the universe. And I hope, Jill, that someday we will find evidence that there is intelligent life among humans on this planet. (Chuckles) Did I say that? I guess I did.

People ask: Why should I care about the ocean? Because the ocean is the cornerstone of earth's life support system, it shapes climate and weather. It holds most of life on earth. 97% of earth's water is there. It's the blue heart of the planet — we should take care of our heart. It's what makes life possible for us. We still have a really good chance to make things better than they are. They won't get better unless we take the action and inspire others to do the same thing. No one is without power. Everybody has the capacity to do something.

Kept here, labelled, rather than mixed in above.

The ocean is large and resilient, but it is not too big to fail. What we are taking out of the sea, what we are putting into the sea are actions that are undermining the most important thing the ocean delivers to humankind – our very existence.

No ocean, no life. No blue, no green. No ocean, no us.

Without an ocean, there would be no life-no people anyway

There's plenty of water in the universe without life, but nowhere is there life without water.

The living ocean drives planetary chemistry, governs climate and weather, and otherwise provides the cornerstone of the life-support system for all creatures on our planet, from deep-sea starfish to desert sagebrush. That's why the ocean matters. If the sea is sick, we'll feel it. If it dies, we die. Our future and the state of the oceans are one.

Sometimes, I try to imagine what intelligent aliens, viewing Earth from afar, might think about the sea. From their perch in the sky, they could immediately see what many earthlings never seem to grasp: that this is a planet dominated by saltwater! In fact, the ocean is the cornerstone of the systems that sustain us: every breath we take is linked to the sea.

Sometimes I try a poetic approach and describe how luminous, rainbow-colored jellies, starlike planktonic creatures, giant squid, translucent pink prawns, gray dolphins, brown lizards, spotted giraffes, emerald mosses, rustling grasses, every leaf on every tree and all people everywhere, even residents of inland cities and deserts who may never see the sea, are nonetheless dependent upon it.

Common sense forces me to consider first the incredible sweep of time that preceded this moment and the ocean's great age, relative to the infinitesimally small fragment of time enjoyed thus far by humankind.

Our soaring population may suggest success as a species, but the environmental price of modern civilization is high, and our prosperity may be short-lived.

In the rush to "develop" and use the legacy 4.6 billion years in the making, we have struck the earth like a slow-motion comet, wielding powerful new forces of change, rivaling and compounding the impact of natural storms, volcanoes, earthquakes, disease, fires-even, it now seems, nudging the grand and gradual planetary processes that cause ice ages to come and go.

Highways crisscross the land, simultaneously forming pathways and barriers.

This much is certain: We have the power to damage the sea, but no sure way to heal the harm.

All things considered, it seems so reasonable that people should care about the oceans and should be driven by a sense of urgency about knowing more. One of the great unsolved mysteries of the sea is why they don't. An aquatic atmosphere covers most of the planet's surface, encompasses the continents, and provides a home for most of life on Earth, yet it remains for humankind inaccessible and unknown, by and large ignored, overlooked, or simply taken for granted. How is this possible?

Since the 1800's, numerous species and entire complex living ecosystems many millions of years in the making have been decimated or significantly altered, from populations of whales and other large mammals to dozens of commercially valued fish species, all marine turtles, many sharks, and numerous small creatures including certain krill, crabs, and shrimp. Worldwide, the living network of microorganisms that shape the basic ingredients of the ocean's "living soup" has been tugged, the system nudged, with unknown consequences. Far too little is known about the earth's living processes to know or predict the specific consequences of our tinkering, but the outcome is not likely to be favorable for humankind.

Curiously, those who claim to believe that the earth and all living things were created by God in fact appear to place greater value on human works and the judgment of mankind.

No one can say for sure what such disruptions may mean for human well-being or survival; clearly, however, a global experiment is in progress, and we are in the middle of it, as a part of, not apart from, the rest of life on Earth. Unlike most other participants, though, we have the ability to alter the course of events, and we shall, either through conscious decisions aimed at making a difference, or by default, through inaction or ignorance.

This is a time of pivotal, magnified significance for humankind. The fabric of life and the physical and chemical nature of the planet have been significantly altered through decisions already made by our predecessors and those now living; what happens next depends on what we do, or do not do, individually and collectively, in the next few decades. Depending on choices we make, our species may be able to achieve a viable, sustainable future, or we may continue to so alter the nature of the planet that our kind will perish.

on balance, if I had to choose the most interesting and important time in all of human history to live, it would be now. As never before, and perhaps as never again, the choices made in the near future will determine mankind's success, or lack of it. These are the "good old days" sure to be envied by those in the future.

Far and away the greatest threat to the sea and to the future of mankind is ignorance. But with knowing comes caring, and with caring, the hope that maybe we'll find the Holy Grail of understanding, strike a balance with the natural systems that sustain us, and thus achieve an enduring place for humankind on a planet that got along without us for billions of years and no doubt could do so again.

As I walked solemnly over the blackened, blistered remains of what had been a friend's home, it was clear that those with whom I share the present time matter most: family, friends, acquaintances, members of my species throughout the world, and ranging beyond humankind, to other creatures I know personally or have met and admired on their own terms, from great humpback whales who turned their eyes to meet mine to the three Stellar's jays that recently fledged from a nest over my backdoor. I wish them well, want them to prosper, will take measures to protect them, if I can...

(My parents and grandparents) witnessed the start of an era of unprecedented global consumption of living resources, the transformation of an earthly paradise 4.6 billion years in the making skimmed for the short-term service of a single insatiable species.

Despite clear evidence that ocean ecosystems are collapsing and fish populations can not sustain commercial taking, huge nets, trawlers, and factory ships are still being deployed, and more are being built.

In the past few decades-my lifetime-the sea has changed; with each passing year, pressures on ocean resources and ocean ecosystems increase; the size of the ocean does not.

A few individuals, armed with modern technology, can wield enormous destructive power. One person with a bulldozer can, in a few days, eliminate a forest that has been quietly building for millennia; one fisherman deploying miles of drift nets can wipe out entire seagoing societies...But just as individuals can and do negatively impact the course tory, so can and do individuals make a positive difference.

Part of human impact on the earth relates to our swiftly growing numbers. If we do not take deliberate, conscious action to maintain a reasonable balance between the numbers of people and the environmental wealth required to sustain us, nature will make appropriate adjustments, and famine, disease, and wars-the predictable outcomes of living beyond one's environmental means, of overspending environmental capital-will ultimately force a cruel discipline.

One of my personal heroes is William Perrin

To ensure a decent quality of life for the rest of our lives, as well as for all those who follow, we must develop global policies that recognize the interdependence of life and the need for nations to agree on mutually beneficial measures to protect and maintain the basic elements of life support, on a planetary scale. But it is difficult to be concerned

If I had to name the single most frightening and dangerous threat to the health of the oceans, the one that stands alone yet is at the base of all the others is ignorance: lack of understanding, a failure to relate our destiny to that of the sea, or to make the connection between the health of coral reefs and our own health, between the fate of the great whales and the future of humankind. There is much to learn before it is possible to intelligently create a harmonious, viable place for ourselves on the planet. The best place to begin is by recognizing the magnitude of our ignorance, and not destroy species and natural systems that we cannot re-create nor effectively restore once they are gone.

Perhaps with knowing will come caring, and with caring, an impetus toward the needed sea change of attitude, one that combines the wisdom of science and the sensitivity of art to create an enduring ethic.

We have an opportunity, now, to achieve for humankind a prosperous, enduring future. If we fail, through inability to resolve thorny issues, or by default born of indifference, greed, or lack of knowledge, our kind might well be a passing short-term phenomenon, a mere three or four million-year blip in the ancient and ongoing saga of life on Earth.

“Green" issues make headlines these days, but many seem unaware that without the "blue" there could be no green, no life on Earth and therefore none of the other things that humans value. Water-the blue-is the key to life. With it, anything is possible; without it, life does not exist.

Only here in this part of the universe, on Earth, is there known to be a place naturally blessed with abundant, liquid water. Not only is this the singular place with an ocean of salt water, but even more significant, it is an ocean that is filled with life that in turn, during some four billion years, has shaped the basic rocks and water of the planet into a strikingly different kind of place, a place unlike any known to exist anywhere else.

Astronomer Carl Sagan noted that even when it is viewed from so far away that it is a pale dot, Earth is discernibly blue.

Without the legions of minuscule organisms that have preceded us over the ages and whose descendants surround us and support us still, life as we know it could not exist.

The ocean drives climate and weather, regulates temperature, absorbs much of the carbon dioxide from the atmosphere, holds 97 percent of Earth's water, and embraces 97 percent of the biosphere. Far and away the greatest abundance and diversity of life occurs in the ocean, occupying liquid space from the sunlit surface greatest depths.

Even if you never have the chance to see or touch the ocean, the ocean touches you with every breath you take, every drop of water you drink, every bite you consume. Everyone, everywhere is inextricably connected to and utterly dependent upon the existence of the sea.

Earth's life-support system-the ocean-is failing. But who is paying attention?

two things changed in the 20th century that may jolt us into a new way of thinking. First, more was discovered about the nature of the ocean and its relevance to the way the world works than during all preceding history. Second, during the same narrow slice of time, human actions caused more destruction to ocean systems than during all preceding history. And the pace is picking up.

most of all, it matters that the world is blue because our lives depend on the living ocean-not just the rocks and water, but stable, resilient, diverse living systems that hold the world on a steady course favorable to humankind. The big question is, what can we do to take care of the blue world that takes care of us?

I now know, the horseshoe crab and thousands of other ancient, resilient creatures may not survive the impact my species has had on the living world, largely in a single century. More worrisome, humankind may not survive for long, either, unless we use our remarkable capacity to learn from the past, anticipate the consequences, and take actions that will ensure an enduring future. As it turns out, the future of the ocean, the creatures who live there, and our own future are inextricably linked.

I certainly was unaware that the ocean globally was on the verge of cataclysmic decline, that the pristine seas I had known as a child were in danger of becoming Paradise Lost. I was not alone in not knowing. Rachel Carson, famous for her 1962 classic Silent Spring, 11 years earlier wrote in The Sea Around Us: "Eventually man...found his way back to the sea.... And yet he has returned to his mother sea only on her own terms. He cannot control or change the ocean as, in his brief tenancy of earth, he has subdued and plundered the continents."

Perversely, the natural living systems that over billions of years have generated and shaped planetary chemistry in ways that make Earth hospitable for humankind are being destroyed at breathtaking speed. This, too, we now know. Now that I know, I hope to convey a sense of urgency to others, to inspire use of the special powers that humans possess to take actions to protect what remains and restore whatever we can of the natural living systems that give us life, and provide the underpinnings of all we hold near and dear.

But taking a small number of wild creatures out of large populations while protecting-not destroying the habitat is very different from the industrial-scale extraction of wildlife now taking place in the sea. These issues seemed to intrigue President George W. Bush during a conversation over dinner at the White House in April 2006.

High on my short list of heroes for science-based ocean conservation is Graeme Kelleher, for 25 years the chairman of Australia's Great Barrier Reef Marine Park Authority, and for his entire career a proponent of marine protected areas.

I'm haunted by the thought of what Ray Anderson calls "tomorrow's child," asking why we didn't do something on our watch to save sharks and bluefin tuna and squids and coral reefs and the living ocean while there still was time. Well, now is that time. I hope for your help to explore and protect the wild ocean in ways that will restore the health and, in so doing, secure hope for humankind. Health to the ocean means health for us.

And I hope Jill Tarter's wish to engage Earthlings includes dolphins and whales and other sea creatures in this quest to find intelligent life elsewhere in the universe. And I hope, Jill, that someday we will find evidence that there is intelligent life among humans on this planet.

The poet W. H. Auden said, "Thousands have lived without love; none without water." Ninety-seven percent of Earth's water is ocean. No blue, no green. If you think the ocean isn't important, imagine Earth without it. Mars comes to mind. No ocean, no life support system.

Tim Worth says the economy is a wholly-owned subsidiary of the environment. With every drop of water you drink, every breath you take, you're connected to the sea. No matter where on Earth you live. Most of the oxygen in the atmosphere is generated by the sea. Over time, most of the planet's organic carbon has been absorbed and stored there, mostly by microbes. The ocean drives climate and weather, stabilizes temperature, shapes Earth's chemistry. Water from the sea forms clouds that return to the land and the seas as rain, sleet and snow, and provides home for about 97 percent of life in the world, maybe in the universe. No water, no life; no blue, no green.

fortunately, in our time, we've learned more about the problems than in all preceding history. And with knowing comes caring.

Protected areas provide hope that the creatures of Ed Wilson's dream of an encyclopedia of life, or the census of marine life, will live not just as a list, a photograph, or a paragraph.

I suppose you want to know what my wish is. I wish you would use all means at your disposal -- films, expeditions, the web, new submarines -- and campaign to ignite public support for a global network of marine protected areas -- hope spots large enough to save and restore the ocean, the blue heart of the planet. How much? Some say 10 percent, some say 30 percent. You decide: how much of your heart do you want to protect? Whatever it is, a fraction of one percent is not enough. My wish is a big wish, but if we can make it happen, it can truly change the world, and help ensure the survival of what actually -- as it turns out -- is my favorite species; that would be us. For the children of today, for tomorrow's child: as never again, now is the time.

there is a basic ethical attitude: respect for life, respect for other humans, certainly, but for all forms of life. It’s something that if everyone could just realize how special it is to be alive on this little blue speck in the universe, it’s a miracle that life exists at all and that we have a piece of time that is ours — whoever we are, shorter or longer, whatever it is, but — to really be a part of the action and to respect where we have come from, where we might be going.

I feel like a witness to—I am—to the greatest era of change on the planet as a whole. Anybody who’s been around even for ten years is a part of this, but the longer you’ve been around, the more you’ve seen. And the last half-century, in particular, has been a time of revolutionary change. We didn’t know the existence of those great mountain chains, hydrothermal vents, the existence of life in the deepest sea, seven miles down. Nobody had been there. Not until 1960 was it possible for two men to make a descent to the deepest part of the sea.

There’s heaven on earth. It just happens to be in the ocean.

Diving into the ocean, it’s like diving into the history of life on earth, not just over the last 50 or 1,000, but the last million, 10 million, 100 million years, because creatures are there that have been there for several hundred million years, not those same creatures, but their near relatives, like jellyfish; like — well, sharks have been around for 300 million years; horseshoe crabs, creatures that lured me into the ocean as a child in New Jersey, have a history that goes back at least 300 million years; so many forms of life that were found in the ocean long before there were multicellular creatures occupying space on the land.

that’s the joy of being a scientist and an explorer. You do what little children do. You ask questions, like: Who? What? Why? When? Where? How? And you never stop, and you never cease being surprised. You just never stop that sense of wonder. It is fantastic that life exists at all. And I revel in just the joy of being out in some wild place, or even in my own backyard. Just look at a leaf. It’s an amazing thing what goes on in a leaf; and it happens all the time, and we can breathe because of it, or because of photosynthesis that takes place there and in the sea. Knowing that, I think it’s just impossible to be bored.

we know that with cats and dogs and horses and kids, humans, every face is really different. But it’s true with all forms of life.

there’s a chemistry of life that has this capacity for enormous variation, maybe infinite variation. It’s a source of endless wonder and something that — it’s worth using our minds, that special gift that we have. There are other intelligent creatures out there — whales, dolphins, elephants, fish. Some of them are really smart. But they don’t know what we know. They can’t see the inside of a star or the inside of a starfish — except some of them, maybe, to eat them. But we have this power not only to explore, but we can go back in time. We can anticipate the future, far into the future. We can plot a course for ourselves based on intelligence. And the trick is: OK, homo sapiens, the smart ones, the wise ones — let’s take advantage of that capacity...Let’s put that into action and not just be like the bacteria on a dish that consume everything until they die. We don’t have to do that.

If I were an evil alien wishing to alter the nature of life on earth, I would change the temperature of the ocean, I would change the chemistry. That is exactly what we are doing: excess carbon dioxide in the atmosphere becomes excess carbon dioxide in the ocean that becomes carbonic acid. The ocean is becoming more acidic. That changes everything.

(What is the single most important thing we can do for the oceans today?) Right now a disproportionate bite out of the ocean is being taken by a relatively small number of countries doing industrial fishing. We’ve got to get over this idea that wildlife from the ocean is essential for our food security. What we now are beginning to understand is the high cost of eating fish. What does it take to make a pound of tuna? A lot of halibut or cod. What makes the halibut? Smaller fish. What do they eat? Krill. Krill eat phytoplankton, zooplankton. Over the years thousands of pounds of phytoplankton make a single pound of tuna. So that tuna is expensive in terms of the carbon that it has captured. The more fish we take out of the sea, the more carbon dioxide gets released into the atmosphere.

(What is the biggest threat to the ocean right now?) Deep-sea mining. Some are buying into the lie that we should be taking minerals that are necessary for today’s generation of [EV] batteries, like lithium, cobalt and nickel, from the deep sea, because who cares what happens in the deep sea? These deep-sea systems are full of life and are part of the biogeochemical cycling systems that hold Earth steady. If Earth functions like a big computer system with all these little wires and lights that we don’t understand but we know it keeps us alive, would we want to get in there and take those little lights out because we don’t understand how they work?

I’ve had the privilege of living underwater on 10 different occasions. It has enabled me to get to know individual moray eels, individual groupers, even individual lobsters. They all have faces, they have attitudes. They have sensory systems much like our own. And yet we somehow harden ourselves to think they don’t feel pain. We pride ourselves on being “humane” but it doesn’t translate to the way we treat animals in the sea.

Knowledge is the superpower of the 21st century. Even the smartest people alive when I was born did not know what 10-year-olds today have available to them. That’s truly cause for hope.

The ocean is the blue heart of the planet.

Change happens because of individuals who team up with others or inspire others. And soon you’ve got 10 or 100 or 1,000, and then you’ve got a movement.

I've had a chance to live underwater 10 times now in various underwater laboratories and to use more than 30 different kinds of submarines, thousands of hours seeing the ocean from the inside out and realizing this is not just rocks and water; this is alive. It's a soup, like minestrone, but all the little pieces are alive.

Being a child in Florida when my parents moved there in 1948 and witnessing the changes in the coastline, the marshes that I first discovered - finding horseshoe crab eggs, these tiny little creatures prospering in really clear water and going out on a dock at night and seeing these bioluminescent creatures just flashing and glowing - and witnessing the change, that the waters became not beautiful, clear and blue but muddy - that was powerful incentive to say, why are we doing this?

it's still there - the habit of thinking that the ocean is too big to fail. And we're still taking life in the ocean for granted. We still think that we have the capacity to take fish on a scale that we currently are and continue to do it forever.

I think one of the most important trends is the awareness and willingness to embrace places and to recognize that protecting nature, the natural systems, have benefits back to us in terms not just of better health, not just because they're beautiful - it's not even a choice anymore; it's necessary for our existence. We have to realize we're a part of nature. We can see the connection between trees and climate. We can see connection between the forests and the ocean, the phytoplankton capturing carbon, generating oxygen, maintaining a planet that works in our favor. This is common sense.

we can't be happy or healthy if we don't take care of our life support system, the planet.

The 21st century humans are poised to be the heroes for all time because we're armed with a superpower of knowing that we have to change our attitude about the world that keeps us alive, that we can't just continue mining and, you know, taking and taking. We have to be aware of the consequences.
