A few months ago I happened to pick up a copy of Jacques Cousteau’s classic first book, The Silent World, less from a burning desire to read it than for the mysterious and evocative cover photo, and out of a sense of comradely solidarity with this pioneer submariner. It gathered dust on my bedside table for a while, as books often do, before the opportunity arose to read it, in this case during a week on the Outer Banks of North Carolina, a place, appropriately enough, dominated by the edge of the Ocean.
What a book. I would be the first to admit that Cousteau is not the most talented writer — the prose is often pedestrian and the organization a bit clunky. But this is not a novel to be read for the art of its language. This is the real McCoy. It is a tale of exploration of a fabulous new world hitherto almost completely unknown. After reading The Silent World, I’m left with the powerful sense that Cousteau was an explorer in the classical mold, in the company of Columbus, Lewis and Clark, and the early astronauts.
It’s fashionable in some professional circles to dismiss Cousteau with a condescending wave. He was not a “real oceanographer”, they might say, and this is true enough. He had no formal training in marine biology, though he did have the naval Captain’s years of practical knowledge of the Sea. And he had some engineering background. Many passages in the book describe activities that the team undertook in the name of research to learn about animal behavior and diving physiology and so on, which seem quaintly sophomoric to us in the modern world where we’re accustomed to seeing the wonders of the universe in high-definition while we loaf on the living room sofa.
But that is part of the point. Cousteau was not an egghead product of the universities as many of us are know. There was essentially noone to teach him the skills and understanding that we take for granted today, either as marine biologists or sport divers. He was, to use the old cliche, a student in the school of hard knocks. He and his buddy Emil Gagnon invented underwater breathing, something that humans had been trying to figure out for literally thousands of years. That alone is enough to qualify him for heroic status.
But there’s more. The human stories behind the Cousteau saga are fascinating. The aqua-lung, as they called their creation, was cobbled together from scrounged parts while Cousteau and his homies were laying low in Nazi-annexed France during the war. They tested the thing out in a hidden cove to escape the attention of Italian occupation troops. They fed themselves in those lean times by spearing fish. Everything was trial and error, including terrifying dives to great depths, in caves, and such places where divers not infrequently passed out or lost their bearing from nitrogen narcosis. Some never came back.
After the war, as a naval officer, Cousteau was detailed to Marseilles to run “a collecting center for returning sailors in a commandeered castle.” He convinced his superiors that the aqua-lung had promise in a variety of naval applications and wheedled their permission to conduct a series of explorations. His buddy Taillez quit his job as a forest ranger, and a motley crew was assembled as the “Undersea Research Group.” Their activities included location and salvaging of wrecks, which led them eventually to the wrecks of cargo ships from classical times, the merchant marine of Greece, Phoenicia, Carthage, and Rome. The treasures they found had been sitting on the bottom of the Mediterranean since they sank two millennia ago, and offered unprecedented insights into the life of those times. Cousteau was, without a doubt, larger than life.

“I have recounted how the first goggles led us underwater in simple and irresistible curiosity, and how that impulse entangled us in diving physiology and engineering, which produced the compressed-air lung. Our dives are now animated by the challenge of oceanography. We have tried to find the entrance to the great hydrosphere because we feel that the sea age is soon to come.”
Reading these tales of high adventure half a century or more later inevitably brings the wistful sense, all too familiar nowadays, of what has been lost from the oceans, which were still comparatively virgin in the 1940s and 1950s when Cousteau first penetrated them. The descriptions of schools of gigantic fishes moving placidly among colorful reefs, which Cousteau and company were the first humans to see in their natural habitat, are almost nowhere to be found in the world oceans of today. But I am willing to bet that the situation would be far worse had the mysteries and beauty of the Ocean world not been brought to such wide popular attention by Cousteau’s lifelong passion.
What “professional” ocean scientist today can claim that kind of victory?










Consider the impact that this single unsung man (so unsung, in fact, that the pixelated snapshot above is the only one I could find of him online!) has had on the environmental awareness of an entire generation — perhaps even two or three generations — of American citizens. Who can say how many kids in the 50s and 60s and 70s decided, while browsing through one of these little books, to spend the afternoon outside hunting for caterpillars instead of yielding to the seductive stupor of the cathode ray tube? Who can say how many of today’s alternative energy entrepeneurs and scientists and educators and conservationists caught fire as a result of a spark generated by one of these books? I can’t, but I know one: me.
When I was a kid, my family drove cross-country (in a van without air-conditioning that was prone to overheating in the desert and climbed the Rockies at about 18 mph, etc.), from Arlington, Virginia to LA, every three years, where we spent the bulk of three weeks visiting my aunt and her family. When I tell people this they think my parents were crazy. But it was a the adventure of a lifetime and an incomparable learning experience for kids. We saw a lot of the country, did a lot of camping, and my parents occasionally allowed us to visit the cheesy fake Indian trinket shops that were common along the dustier stretches of Route 66 in the olden days. One day when I was probably about seven (this would have been the late 1960s), we were visiting Walnut Canyon, which is somewhere in the southwest, and I convinced my parents to buy me the Golden Nature Guide to Rocks and Minerals. I felt so grown up to have a real book instead of a kid’s book. It was an early watershed moment in my life as a bookworm and naturalist.
Nevertheless, I was not destined to be a geologist. For one thing, rocks are dead. Or so they seemed to me. I found animals much more interesting. Second anecdote: Around the same time, in second grade, I became obsessed with turtles. I take this herpetophilia to be a common, though poorly understood, genetic trait located somewhere on the Y chromosome, since it is so commonly expressed among young boys. This is despite the fact that my white-bread suburban neighborhood turned out, to my dismay, to be nearly devoid of reptiles. I saw maybe two or three box turtles, and no snakes at all, in the wild while I was growing up despite frequent expeditions mounted for that purpose to the local park where I spent much of my youth. But I can remember sitting rapt with the pocket-sized Golden Guide to Reptiles and Amphibians, studying the pictures, memorizing what they ate, looking at the ingenious maps that showed purple where the summer (pink) and winter (blue) ranges overlapped. This genetic propensity has in fact been transferred to my son, who latched on to my antique Reptile guide in an uncannily similar way and spent a lot of time with it (it is now bound with duct tape).
It appears that I’m not the only one with such fond memories. Evidently the original versions of the Guides have recently become “

An emerging body of scientific knowledge links nature time to longer attention spans, better cognitive functioning, reduction of stress, and strengthened family bonds. What better way to enhance parent-child attachment than to walk in the woods together, disengaging from distracting electronics, advertising, and peer pressure?
1. Go for a family walk when the moon is full. There’s a whole new set of animals, sights and sounds out there. Listen to animals calling. Owls and bats are looking for prey. Watch for things glowing, like worms and fungus on trees. And look up at the stars.
3. Tell your children stories about your special childhood places in nature. Then help them find their own: leaves beneath a backyard willow, the bend of a creek, the meadow in the woods. Let it become their intimate connection with the natural world.
5. Invent your own nature game. One mother’s suggestion: “We help our kids pay attention during longer hikes by playing “find ten critters” — mammals, birds, insects, reptiles, snails, and other creatures. Finding a critter can also mean discovering footprints, mole holes, and other signs that an animal has passed by or lives there.”
Now that’s what I’m talking about.
“Restoration ecology” is not quite the appropriate term since some of the plants they foster are not native to their specific region. On the other hand, they do support native insects, and therefore higher levels in the food web. And in any case, as climate change and other environmental impacts progress, we need to shift our focus to “emerging ecosystems”. While remaining (or becoming) aware of the sometimes forgotten baselines of how nature used to look and work, we also need to incorporate the reality that geographc ranges of species are shifting, some invaders are here to stay, and some natives are disappearing inexorably. How do we maintain biodiversity and functional, resilient ecosystem in this new world order?
extremely finicky eaters. Many are strict specialists on one or a few types of plants. This means that yards and gardens filled with ornamental plants introduced from elsewhere often support only invasive pest species and not the native insects adapted to local conditions and enjoyed by local birds and other animals. Encouraging native plants — and insects — is a concrete way to restiore ecological balance to the patches of land over which we personally have stewardship.
As the evidence for ongoing climate change has grown incontrovertible, there is increasing urgency to the question of what these changes hold in store for us.
The Figure at left shows the northern hemisphere temperature variation (as anomalies from the long-term average, panel A), war frequency, and rate of change in human population from 1400 to approximately the beginning of the industrial revolution in 1900. The number of wars is shown for the northern hemisphere as a whole (bright green line, and right axis scale), Asia (pink), Europe (turquoise), and arid areas of the northern hemisphere (orange). Panel C shows number of wars worldwide as recorded by three different authors using different thresholds for defining war — as can be seen, the trends are roughly similar. Finally, panel D shows the 20-year population growth rate in Europe (turquoise), Asia (pink), and the northern hemisphere as a whole (blue), as well as the 50-year fatality index in the region (bright green). Cold phases of history are shaded in gray. The bright green curves correspond to the right axis. 
The figure at right summarizes in diagrammatic form the pathways by which long-term climate variation influenced frequency of war and human population dynamics in China and Europe during preindustrial times (i.e. up to 1900). Solid lines indicate direct effects, and dotted lines indirect feedbacks. Thicker arrows indicates stronger correlations. There are several inrerrelated impacts of climate change mediated by the interactions of humans with our food supply and with each other, but food supply is central.

An honor such as this comes with responsibility of course. And in the characteristic pyramid-scheme modus operandi of the blogosphere, mine is to finger ten more blogs that I deem “excellent!” I am of course delighted to do so. Thus, in no particular order:

And now, as the Pythons say, for something completely different. I realize that this is a bit peripheral to the mainsteam content of this blog but (as another famous person said), “I’m the decider”.
The Grim finding (I’m sorry — that was inexcusable) was that the number of papers published, the total number of citations received, and the average number of citations per paper all declined significantly with quantity of beer consumed (see the graph at left). These results were consistent across both 2002 and 2006 data sets. And get this, you Bohemians:
