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.
With every drop of water you drink, every breath you take, you're connected to the sea. No matter where on Earth you live.
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.
Rather than be afraid of evolution and try to stifle inquiry, people should revel in the joys of knowing and find a serenity and a joy in being a part the rest of life on Earth. Not apart from it, but a part of it.
We are all together in this, we are all together in this single living ecosystem called Planet Earth. As we learn how we fit into the greater scheme of things, and begin to understand how the system works, we can plan ahead, we can use the resources responsibly, to show some respect for this inheritance that goes back 4.6 billion years.
If you think the ocean isn't important, imagine Earth without it. Mars comes to mind. No ocean, no life support system.
In the past few decades, Earth's natural systems have endured more pressure than in all preceding human history.
The diversity of life on Earth, generally, is astonishing. But despite those large numbers, it's also important to recognize that every species, one way or another, is vulnerable to extinction. And in our time on Earth... our impact on the diversity of life has been profound.
Fortunately, we know more about the problems that we have than in all preceding history. We know now the consequences of the things that we put into the air, into the water - of the way we treat life on Earth.
The image of Earth from space transformed our view of ourselves. It is maybe the most important image that exists - because we can see ourselves in context in a way that otherwise would be really hard to explain. It should inspire us to wonder about it, to want to know everything we can about it and do everything we can to take care of it.
The Earth is a unique system in the universe, the only planet we know of that's hospitable for humankind.
If Darwin could see what we now see, what we now know about the ocean, about the atmosphere, about the nature of life, as we now understand it, about the importance of microbes - I think he would just beam with joy that many of the thoughts and the glimpses of the majesty of life on Earth that he had during his life, now magnified many times over.
We are all together in this, we are all together in this single living ecosystem called planet earth.
It doesn't matter where on Earth you live, everyone is utterly dependent on the existence of that lovely, living saltwater soup. There's plenty of water in the universe without life, but nowhere is there life without water.
Why does evolution matter? There is so much about the evolution of life, the development of life on Earth that should rivet the attention of everyone to understand where we've come from and where we might be going. We need to understand the world around us if we are to succeed as a species on the planet.
No creature on Earth ever has organized themselves in ways that we have, with the capacity to alter the nature of nature the way we have.
It has taken these many hundreds of millions of years to fine-tune the Earth to a point where it is suitable for the likes of us.
Life in the ocean makes Earth hospitable. We are sailing along in the universe and we have a blue engine that is making everything alright.
Most of life on Earth has a deep past, much deeper than ours. And we have benefited from the distillation of all preceding history, call it evolutionary history if you will.
The Earth is a tiny blue speck in a universe of unfriendly options.
