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. Sylvia Earle More Quotes by Sylvia Earle More Quotes From Sylvia Earle 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. Sylvia Earle coral-reefs resilience loss 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. Sylvia Earle ocean attitude children 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. Sylvia Earle ice-and-snow temperature home Santa Monica Bay is less polluted today than when I first moved to the area in the 1970s, because actions have been taken to avoid putting some of the noxious materials into the sea. I think people are more aware than they once were, the air is cleaner, water generally is, in spite of the fact that there are more people. Sylvia Earle taken air thinking 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. Sylvia Earle doe attention needs The observations that have developed over the years have given us perspective about where we fit in. We are newcomers, really recent arrivals on a planet that is four and a half billion years old. Sylvia Earle perspective half years When some people look at a shrimp they think, "Hmm. Delicious." When I look at a shrimp I think, "You're a miracle, absolutely incredible. Your ancestors have gone back hundreds of millions of years." And to develop a thing as simple as a shrimp cocktail, you have to calculate the hundreds of millions of years that have preceded that moment where you're sitting there with your sauce and fork poised. Sylvia Earle simple years thinking 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. Sylvia Earle deeper earth past 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. Sylvia Earle tunes taken years 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. Sylvia Earle impact numbers profound 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. Sylvia Earle ocean joy thinking 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. Sylvia Earle you nature sea water Bottom trawling is a ghastly process that brings untold damage to sea beds that support ocean life. 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? Sylvia Earle butterfly ocean sea life Every fish fertilizes the water in a way that generates the plankton that ultimately leads back into the food chain, but also yields oxygen, grabs carbon - it's a part of what makes the ocean function and what makes the planet function.
