Bluefin Tuna Fact of the Day


"The BP oil spill in the Gulf of Mexico, one of only two known Atlantic bluefin spawning grounds, has only intensified the crisis. By some estimates, there may be only 9,000 of the most ecologically vital megabreeders left in the fish’s North American stock, enough for the entire population of New York to have a final bite (or two) of high-grade otoro sushi. The Mediterranean stock of bluefin, historically a larger population than the North American one, has declined drastically as well. Indeed, most Mediterranean bluefin fishing consists of netting or “seining” young wild fish for “outgrowing” on tuna “ranches.” Which was why the Greenpeace craft had just deployed off Malta: a French fishing boat was about to legally catch an entire school of tuna, many of them undoubtedly juveniles."

Freeman Dyson profile



Among Dyson’s gifts is interpretive clarity, a penetrating ability to grasp the method and significance of what many kinds of scientists do. His thoughts about how science works appear in a series of lucid, elegant books for nonspecialists that have made him a trusted arbiter of ideas ranging far beyond physics. Dyson has written more than a dozen books, including “Origins of Life” (1999), which synthesizes recent discoveries by biologists and geologists into an evaluation of the double-origin hypothesis, the possibility that life began twice; “Disturbing the Universe” (1979) tries among other things to reconcile science and humanity. “Weapons and Hope” (1984) is his meditation on the meaning and danger of nuclear weapons that won a National Book Critics Circle Award. Dyson’s books display such masterly control of complex matters that smart young people read him and want to be scientists; older citizens finish his books and feel smart.

Yet even while probing and sifting, Dyson is always whimsically gazing into the beyond. As a boy he sketched plans for English rocket ships that could explore the stars, and then, in midlife, he helped design an American spacecraft to be powered by exploding atomic bombs — a secret Air Force project known as Orion. Dyson remains an armchair astronaut who speculates with glee about the coming of cheap space travel, when families can leave an overcrowded earth to homestead on asteroids and comets, swooping around the universe via solar sail craft. Dyson is convinced that our current “age of computers” will soon give way to “the age of domesticated biotechnology.” Bio-tech, he writes in his book, “Infinite in All Directions” (1988), “offers us the chance to imitate nature’s speed and flexibility,” and he imagines the furniture and art that people will “grow” for themselves, the pet dinosaurs they will “grow” for their children, along with an idiosyncratic menagerie of genetically engineered cousins of the carbon-eating tree: termites to consume derelict automobiles, a potato capable of flourishing on the dry red surfaces of Mars, a collision-avoiding car.

These ideas attract derision similar to Dyson’s essays on climate change, but he is an undeterred octogenarian futurist. “I don’t think of myself predicting things,” he says. “I’m expressing possibilities. Things that could happen. To a large extent it’s a question of how badly people want them to. The purpose of thinking about the future is not to predict it but to raise people’s hopes.” Formed in a heretical and broad-thinking tradition of British public intellectuals, Dyson left behind a brooding England still stricken by two bloody world wars to become an optimistic American immigrant with tremendous faith in the creative imagination’s ability to invent technologies that would overcome any predicament. And according to the physicist and former Caltech president Marvin Goldberger, Dyson is himself the living embodiment of that kind of ingenuity. “You point Freeman at a problem and he’ll solve it,” Goldberger says. “He’s extraordinarily powerful.” Dyson seems to see the world as an interdisciplinary set of problems out there for him to evaluate. Climate change is the big scientific issue of our time, so naturally he finds it irresistible. But to Dyson this is really only one more charged conundrum attracting his interest just as nuclear weapons and rural poverty have. That is to say, he is a great problem-solver who is not convinced that climate change is a great problem.

Dyson is well aware that “most consider me wrong about global warming.” That educated Americans tend to agree with the conclusion about global warming reached earlier this month at the International Scientific Conference on Climate Change in Copenhagen (“inaction is inexcusable”) only increases Dyson’s resistance. Dyson may be an Obama-loving, Bush-loathing liberal who has spent his life opposing American wars and fighting for the protection of natural resources, but he brooks no ideology and has a withering aversion to scientific consensus. The Nobel physics laureate Steven Weinberg admires Dyson’s physics — he says he thinks the Nobel committee fleeced him by not awarding his work on quantum electrodynamics with the prize — but Weinberg parts ways with his sensibility: “I have the sense that when consensus is forming like ice hardening on a lake, Dyson will do his best to chip at the ice.”

Dyson says he doesn’t want his legacy to be defined by climate change, but his dissension from the orthodoxy of global warming is significant because of his stature and his devotion to the integrity of science. Dyson has said he believes that the truths of science are so profoundly concealed that the only thing we can really be sure of is that much of what we expect to happen won’t come to pass. In “Infinite in All Directions,” he writes that nature’s laws “make the universe as interesting as possible.” This also happens to be a fine description of Dyson’s own relationship to science. In the words of Avishai Margalit, a philosopher at the Institute for Advanced Study, “He’s a consistent reminder of another possibility.” When Dyson joins the public conversation about climate change by expressing concern about the “enormous gaps in our knowledge, the sparseness of our observations and the superficiality of our theories,” these reservations come from a place of experience. Whatever else he is, Dyson is the good scientist; he asks the hard questions. He could also be a lonely prophet. Or, as he acknowledges, he could be dead wrong.

To Drill or not to Drill

Accord on the Tire-Gauge Question;
“Senator Obama said we should inflate our tires,” Mr. McCain said, according to a pool report of the evening. “I think we ought to inflate our tires. I’m all for it. The Triple A said we should inflate our tires. But that’s not all we should do.”


Tired of Talking Tires Yet?


Obama pokes at McCain over tire - pressure issue;
In mocking Obama, McCain told a motorcycle rally in Sturgis, S.D.: ''My opponent doesn't want to drill, he doesn't want nuclear power, he wants you to inflate your tires.'' The Republican National Committee widely distributed tire pressure gauges labeled ''Obama energy plan'' and suggested that was the Illinois senator's only idea for reducing oil imports, although both candidates have offered multifaceted energy proposals.

Human Nature meets Mother Nature


Encounters at the End of the World- a great documentary

A review from NYT;
One of the beauties of “Encounters at the End of the World” is that all the furry and floating animals are no more wondrous than the bipeds tramping through and around McMurdo: the linguist turned philosopher, the banker turned bus driver and the female adventurer who, for drama and odd entertainment, likes to have herself zipped up in a carryall bag. (She’s her own baggage.) Mr. Herzog opens his mind, heart and eyes to all these wayfarers who — despite the persistent strain of melancholy that touches each and every person who appears on camera — seem eerily at peace at the bottom of the world. One reason may be that, like Mr. Herzog, more than a few evince a deep-felt pessimism about both the present and the future.

If this were a nature documentary like any other, the casual talk about global warming and other calamities might cast shadows across this bright expanse. But there’s something about Mr. Herzog — including the accidental if now well-practiced comedy that colors even his most dramatic pronouncements — that inevitably keeps his pictures from growing too dark. One reason is beauty, which in his hands has a way of keeping the worst at bay; it is, after all, hard to fully despair in the face of so much of the natural world’s splendors. Another reason, I think, has to do with Mr. Herzog’s seemingly unshakable faith in human beings, who for all their misdeeds at times reach a state of exaltedness. They soar — just like that jellyfish.

A World Free for Tigers

From the World Bank;
TIGER CONSERVATION: MOVING LESSONS LEARNT TOWARDS A WINNING STRATEGY

Related;
Hoisted from Comments by Tony Whitten;
As one of the Bank's team which organized the Tiger Event on June 9 and the author of the blog to which you link, let me give my perspective on this reasonable question. I regard biodiversity protection (e.g. of tigers) as an integral part of development and is part of our obligation to support countries which have signed the Convention on Biological Diversity. The continued survival of wild tigers is a good indicator of sound forest management, rural development strategies, infrastructure development, and governance. The conservation of biodiversity (and other global public goods is a major part of the sustainability agenda) and this is clearly recognized in the MDGs. Biodiversity conservation can also produce significant co-benefits to communities living in and around natural habitats. All the biodiversity work we support is done with a view to social condition and social impact and as such is an integral part of poverty alleviation and economic growth. Details of our large portfolio of biodiversity projects can be found on www.worldbank.org/biodiversity.

Volcanic Rocks can save us from Global warming?

A group of scientists at Columbia has used deep ocean-floor drilling and experiments to show that volcanic rocks off the West Coast and elsewhere might be used to securely sequester huge amounts of carbon dioxide, a greenhouse gas, captured from power plants or other sources. In particular, they say that natural chemical reactions under 78,000 square kilometers (30,000 square miles) of ocean floor off California, Oregon, Washington and British Columbia could lock in as much as 150 years of U.S. carbon dioxide production.

Celebrity endorsements for World Bank

"By committing to help wild tigers, the World Bank is sounding its intention to be a global leader in biodiversity conservation. I commend this commitment and look forward to seeing it in action."

-Harrison Ford

What do the readers think? I've no comment- after all World Bank's motto is a World Free of Poverty.

Life of Guano workers, Peru




Peru Guards Its Guano as Demand Soars Again
  • Guano is an undeniably strenuous enterprise from the perspective of the laborers who migrate to the islands to collect the dung each year. The laborers rise before dawn to scrape the hardened guano with shovels and pick-axes.
  • Many go barefoot, their feet and lower legs coated with guano by the time shifts end in the early afternoon.
  • The workers earn monthly salaries of about $600, more than three times what manual laborers earn in the impoverished highlands, where most of them are from
  • Guano in Peru sells for about $250 a ton while fetching $500 a ton when exported to France, Israel and the United States. Its status as an organic fertilizer has also increased demand, transforming it into a organic niche fertilizer sold around the world.
