I personally have stopped eating seafood.
The sudden release of five million barrels of oil, enormous quantities of methane and two million gallons of toxic dispersants into an already greatly stressed Gulf of Mexico will permanently alter the nature of the area.
The Exxon Valdez spill triggered a swift and strong response that changed policies about shipping, about double-hulled construction. A number of laws came into place.
The concept of ‘peak oil’ has penetrated the hearts and minds of people concerned about energy for the future. ‘Peak fish’ occurred around the end of the 1980s.
The Arctic is an ocean. The southern pole is a continent surrounded by ocean. The North Pole is an ocean, or northern waters. It’s an ocean surrounded by land, basically.
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.
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.
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.
When I write a scientific treatise, I might reach 100 people. When the ‘National Geographic’ covers a project, it communicates about plants and fish and underwater technology to more than 10 million people.
Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.
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.
We are all together in this, we are all together in this single living ecosystem called planet earth.
I actually love diving at night; you see a lot of fish then that you don’t see in the daytime.
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.
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.
Evolution is not something to be feared. It’s to be celebrated, embraced, and understood.
If Darwin could get into a submarine and see what I’ve seen, thousand of feet beneath the ocean, I am just confident that he would be inspired to sit down and start writing all over again.
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.
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.
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.
