Scientists found that up to 6,000 metric tons of sunscreen washes off swimmers annually, and that the sunscreen contains chemicals that lead to bleaching corals. They estimated that up to 10 percent of corals were threatened by sunscreen-related bleaching ...

... the Central Valley, Calif., chinook salmon run, which had historically been one of the West Coast's strongest, fell to record lows this year, prompting concerns about collapse ...

... researchers in North Carolina studied how to raise fish for consumption in tanks ...

... a seafood consumer center in Oregon prepped for a program that would attach bar codes to salmon, allowing consumers to learn who caught the fish, where it was caught, and how it traveled to market ...

... a wetlands restoration project near San Diego passed a milestone when its newly dredged basin was opened to the Pacific. It is hoped the area will become habitat for halibut, grunion, and bass, among other species ...

... a study commissioned by The New York Times found mercury levels in city sushi far above recommended limits. A report released by Oceana found similar results in tuna sampled around the country ...

... Ecuadorian authorities investigated the clubbing deaths of more than 50 sea lions on the Galapagos Islands ...

... several cosmetics companies, including Unilever and L'Oreal, agreed to end the use of an emollient, squalene, that is obtained from the livers of deep-sea sharks ...

... and fifteen years after a six-year-old Japanese girl released a letter inside a balloon, a fisherman discovered it among his flatfish catch.

animals of the Galapagos

The Galapagos are sorely in need of an environmental-justice intervention, what with the increasing number of immigrants from the continent who do not always understand the great value of preserving the plants and animals of those islands.

But letting goats and dogs run free is one kind of problem; the cruel bashing of these sea lions is destructive behavior of a much worse and more reprehensible sort.

And anyway, do we know who the culprits are?  Ecuadorans, or visitors?

Chickens deserve our true friendship! So do fish! So do other sentient beings! Let us learn to be kind.

recovered balloon

OK, cute story, but children should not be encouraged to release balloons.  It is well known that a number of kinds of marine animals eat trash items floating on the surface of the ocean, and get into trouble as a result.

A balloon might very well have got to the ocean floor if it had been eaten by some animal, and when that animal died, its body drifted downward.  In this case, because the girl's note was still intact and legible, it is probably more doubtful that the balloon was ingested.

Chickens deserve our true friendship! So do fish! So do other sentient beings! Let us learn to be kind.

Save the Sea Turtles

Balloons and plastic grocery bags are leading problems with sea turtles ingesting them, thinking they are food.  

In the cold snap a few years ago we rescued 130 Green Turtles.  

30 passed plastic bags or balloons and half of those, 15, died.  

I saw them trying to poop them out and yes, it was gross (I helped clean it up).

The only other turtles that died were ones with advanced pneumonia from going into hibernation with their heads underwater, perhaps another 10.

Balloons and plastic grocery sacks should be illegal in all coastal communities.

Ecology Related

Not really Ocean related, but I thought this was interesting.

70% of the plants that treat cancer and found only in tropical rainforrests.


rainforests and medicine

Thanks, Grey Falcon.  We should realize:

  1. there are plenty of other diseases and conditions, besides cancer, that are treated by medicines derived from tropical organisms; and

  2. not only do plants produce substances made into medicines; many fungi and animals do as well.  Venoms and secretions of animals seem to be of great interest.

This consideration, of the great practical value of tropical organisms, gives a strong argument in favor of E.O. Wilson's contention, that we must strive to identify all species, everywhere, sooner rather than later.

Another, different kind of question inspired by this item is, how much of our knowledge of medicinal uses of tropical organisms depends on ethnopharmacology.  Traditional peoples, especially hunter-gatherers, have deep and ancient knowledge about almost all the organisms that they live near; and when the communication is good between them, ethnologists and us, we can learn things about those organisms that we would not have suspected or even imagined.

For that matter, I wonder where our knowledge of squalene came from.  Was it Polynesians, maybe, who had discovered that the livers of sharks were uniquely useful for certain applications?  Or was it just that there is some sort of chemical database indexing all kinds of substances found in animals?

Chickens deserve our true friendship! So do fish! So do other sentient beings! Let us learn to be kind.

Galapagos again

The Travel section of the New York Times, which has long struck me as a regrettable advertising supplement, doing the nasty job of "discovering" vacation destinations that would be much better off left undiscovered, seems to have started a "Green Traveler" column.  The Galapagos were the subject of the first installment, last Sunday:

http://travel.nytimes.com/2008/01/27/travel/27green.html.

Notice the detail, that more and more Ecuadoreans are migrating to the islands in the hope of profiting from the ecotourism business.

Chickens deserve our true friendship! So do fish! So do other sentient beings! Let us learn to be kind.

pisciculture in North Carolina

This seems to be the most important sentence:

<<
The fish dine on experimental diets that include fish meal and alternative protein sources such as plankton and soy meal pellets.
>>

I had thought of easily-raised insects, e.g. cockroaches, as a possible alternative protein source.  But if plankton and soy work, fine.  We notice that "fish meal" is still in the mix, though; but it would be best not to have to use fish at all as a food for farm-raised fish.

Later in the article, the expression "sustainable feeds" is used.  Elsewhere I have written that I dislike and mistrust the excessive, fashionable resort to "sustainable" and "sustainability."  In this case, the narrow business application makes it acceptable, though inevitably misleading.

Food chains are inherently fragile, mutable, impermanent things.  A position in a food chain can never be "sustainable."

The need (if it is a "need"!) to kill sentient beings in order to live is morally corrosive.  That conduct, and that relationship, can never be "sustainable."

fyi..
