No water, no life. No blue, no green.
Sylvia Earle
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.
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.
Every time I slip into the ocean, it's like going home.
We need to respect the oceans and take care of them as if our lives depended on it. Because they do.
Ice ages have come and gone. Coral reefs have persisted.
In terms of personal choices, let's all think more carefully about where we get our protein from.
Sharks are beautiful animals, and if you're lucky enough to see lots of them, that means that you're in a healthy ocean. 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. 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.
Humans are the only creatures with the ability to dive deep in the sea, fly high in the sky, send instant messages around the globe, reflect on the past, assess the present and imagine the future.
Health to the ocean means health for us.
On a sea floor that looks like a sandy mud bottom, that at first glance might appear to be sand and mud, when you look closely and sit there as I do for a while and just wait, all sorts of creatures show themselves, with little heads popping out of the sand. It is a metropolis.
Like a shipwreck or a jetty, almost anything that forms a structure in the ocean, whether it is natural or artificial over time, collects life.
The best scientists and explorers have the attributes of kids! They ask question and have a sense of wonder. 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.
Look at the bark of a redwood, and you see moss. If you peer beneath the bits and pieces of the moss, you'll see toads, small insects, a whole host of life that prospers in that miniature environment. A lumberman will look at a forest and see so many board feet of lumber. I see a living city.
Why is it that scuba divers and surfers are some of the strongest advocates of ocean conservation? Because they've spent time in and around the ocean, and they've personally seen the beauty, the fragility, and even the degradation of our planet's blue heart.
For humans, the Arctic is a harshly inhospitable place, but the conditions there are precisely what polar bears require to survive - and thrive. 'Harsh' to us is 'home' for them. Take away the ice and snow, increase the temperature by even a little, and the realm that makes their lives possible literally melts away.
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.
Earth as an ecosystem stands out in the all of the universe. There's no place that we know about that can support life as we know it, not even our sister planet, Mars, where we might set up housekeeping someday, but at great effort and trouble we have to recreate the things we take for granted here.
As a child, I was aware of the widely-held attitude that the ocean is so big, so resilient that we could use the sea as the ultimate place to dispose of anything we did not want, from garbage and nuclear wastes to sludge from sewage to entire ships that had reached the end of their useful life.
I've always said, 'Underwater or on top, men and women are compatible.'
If you think the ocean isn't important, imagine Earth without it. Mars comes to mind. No ocean, no life support system.
Everyone has power. But it doesn't help if you don't use it.
Our insatiable appetite for fossil fuels and the corporate mandate to maximize shareholder value encourages drilling without taking into account the costs to the ocean, even without major spills.
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. And there's no question that it is a factor, but it's preceded by the loss of resilience and degradation.
By the end of the 20th century, up to 90 percent of the sharks, tuna, swordfish, marlins, groupers, turtles, whales, and many other large creatures that prospered in the Gulf for millions of years had been depleted by overfishing.
People still do not understand that a live fish is more valuable than a dead one, and that destructive fishing techniques are taking a wrecking ball to biodiversity.
The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents. That, in turn, influences the temperature of the planet. The Arctic is now vulnerable because of the excess carbon dioxide in the atmosphere, with a rate of melting that is stunning.
Ocean acidification - the excess carbon dioxide in the atmosphere that is turning the oceans increasingly acid - is a slow but accelerating impact with consequences that will greatly overshadow all the oil spills put together. The warming trend that is CO2-related will overshadow all the oil spills that have ever occurred put together.
I find the lure of the unknown irresistible.
America gains most when individuals have great freedom to pursue personal goals without undue government interference.
Places change over time with or without oil spills, but humans are responsible for the Deepwater Horizon gusher - and humans, as well as the corals, fish and other creatures, are suffering the consequences.
Meat reared on land matures relatively quickly, and it takes only a few pounds of plants to produce a pound of meat.
Far and away, the greatest threat to the ocean, and thus to ourselves, is ignorance. But we can do something about that.
Since the middle of the 20th century, more has been learnt about the ocean than during all preceding human history; at the same time, more has been lost.
For heaven's sake, when you see the enemy attacking, you pick up the pitchfork, and you enlist everybody you see. You don't stand around arguing about who's responsible, or who's going to pay.
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.
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.
Large areas of the Gulf have escaped being scraped by trawls, crushed by more than 40,000 miles of pipelines, or displaced by one of 50,000 oil and gas wells drilled since the middle of the 20th century. Some places have been deliberately protected.
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.
Forty percent of the United States drains into the Mississippi. It's agriculture. It's golf courses. It's domestic runoff from our lawns and roads. Ultimately, where does it go? Downstream into the gulf.
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.
The end of commercial fishing is predicted long before the middle of the 21st century.
What we once used as weapons of war, we now use as weapons against fish.
The most important thing for people to know about the governance of the Arctic is that we have a chance now to act to maintain the integrity of the system or to lose it. 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.
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.
If somebody dumps something noxious in my back yard, the dumper is the last one I would call on to repair the damage.
I have heard endlessly that fish are so resilient that there is no way that you could exterminate a species. We are learning otherwise.
When I arrived on the planet, there were only two billion. Wildlife was more abundant, we were less so; now the situation is reversed.
All through college, I had frequently been the only girl in a science class - which wasn't such a bad deal.
