Shrimp’s Dirty Secrets: Why America’s Favorite Seafood Is a Health and Environmental Nightmare

Thursday, February 18th, 2010

– Not my first post on this subject.  See: also.

– – – – – – – – – – – –

The environmental impact of shrimp can be horrific. But most Americans don’t know where their shrimp comes from or what’s in it.

Americans love their shrimp. It’s the most popular seafood in the country, but unfortunately much of the shrimp we eat are a cocktail of chemicals, harvested at the expense of one of the world’s productive ecosystems. Worse, guidelines for finding some kind of “sustainable shrimp” are so far nonexistent.

In his book, Bottomfeeder: How to Eat Ethically in a World of Vanishing Seafood, Taras Grescoe paints a repulsive picture of how shrimp are farmed in one region of India. The shrimp pond preparation begins with urea, superphosphate, and diesel, then progresses to the use of piscicides (fish-killing chemicals like chlorine and rotenone), pesticides and antibiotics (including some that are banned in the U.S.), and ends by treating the shrimp with sodium tripolyphosphate (a suspected neurotoxicant), Borax, and occasionally caustic soda.

Upon arrival in the U.S., few if any, are inspected by the FDA, and when researchers have examined imported ready-to-eat shrimp, they found 162 separate species of bacteria with resistance to 10 different antibiotics. And yet, as of 2008, Americans are eating 4.1 pounds of shrimp apiece each year — significantly more than the 2.8 pounds per year we each ate of the second most popular seafood, canned tuna. But what are we actually eating without knowing it? And is it worth the price — both to our health and the environment?

Chemical Exposure Linked to Attention Deficit Disorder in Children

Sunday, January 31st, 2010

So, go ask the folks that make any of the zillion chemicals released into the environment over the last 100 years if they think there’s any chance that their particular chemicals might, in some way, harm people or the environment.  Go ahead and ask – you know what they’re going to say.

A study of New York City students found that phthalate exposure was linked to behavioral problems

Children exposed in the womb to chemicals in cosmetics and fragrances are more likely to develop behavioral problems commonly found in children with attention deficit disorders, according to a study of New York City school-age children published Thursday.

Scientists at Mount Sinai School of Medicine reported that mothers who had high levels of phthalates during their pregnancies were more likely to have children with poorer scores in the areas of attention, aggression and conduct.

Children were 2.5 times more likely to have attention problems that were “clinically significant” if their mothers were among those highest exposed to phthalates, the study found. The types of behavior that increased are found in children with Attention Deficit Hyperactivity Disorder and other so-called disruptive behavior disorders.

“More phthalates equaled more behavioral problems,” Stephanie Engel, a Mount Sinai associate professor of preventive medicine and lead author of the study, said in an interview Thursday. “For every increase of exposure, we saw an increase in frequency and severity of the symptoms.”

A big picture snapshot

Wednesday, December 9th, 2009

– A friend wrote me the other day about CO2 and said that most of the folks who are out there talking about CO2 and its dangers sound a bit like Chicken Little.  He said there must be places out there on the web where one can get a more balanced presentation of the issues.  And asked if I could direct him to such.

– I’m not sure I answered his questions as effectively as I might have.  I could have, for instance, done some research and tried to find web sites for him with more balanced presentations around CO2 and its issues.

– But, instead, I decided to tell him how and why the debate over CO2 has gotten to be so shrill and why many folks these days are sounding like Chicken Little.

– I think the explanation of why things have gotten so shrill is well worth repeating to a wider audience and so I’ve reproduced my friend’s questions and my responses below.

= = = = = = = = = = =   = = = = = = = = = = =   = = = = = = = = = = =

Dennis,

I know your position on global warming.   Here are my thoughts:   First any thing that would get us untangled from the Middle East and every one else that we buy oil from would be a godsend.   Most people don’t realize that Canada and Mexico are our biggest suppliers.   Being tied to any other country the way we are is a bad thing.   I don’t think the oil/coal industries will are willing to have any change in the status quo until the last ounce of oil and coal is gone.   I think they control, to one extent or another, our government.   I believe that without their influence, we would have made massive changes by now.

Now, I would like to understand more about CO2.  I am not ignorant of the chemistry or of the geological history.   My problems is when I hear the side describing the downsides of CO2 they are so one sided that they sound like Chicken Little.

Even though the CO2 increase has great potential for mass disruption of the world’s ecological balance, there must be a little of this that is being balanced by natural processes.   Perhaps,  just not at a rate that we can accept.   Could you send me some web sites with a little balance?

Dave C.

=== and my response:

Dave,

You are right.  The oil/gas/coal industries are not going to recognize the global climate change effects their products produce.   If they did, it would cost them personally a pile of money.   And yes, they do have a huge effect on governments all over the world – especially the U.S. government.

Your question about CO2 is an excellent one and I wish I could do a better job of answering it.

When you say that the people describing the coming problems from rising CO2 levels sound like Chicken Little, I have to agree.   But, you need to also reflect on how the situation got to be like that.

First off, think about the fact that scientific discoveries don’t usually come up for public debate.

And consider that science comes up with some wild and almost unbelievable discoveries fairly often.   Take Dark Matter and Dark Energy for two things.   And Quantum Physics and all of its weird ideas like entanglement and action at a distance.   And the fact that really small things like electrons are not really in one place or another but rather exist in a small cloud of probability that hovers near where we think it actually is.  And how about relativity with its ideas that time slows down as your speed get closer and closer to the speed of light?

All that stuff was discovered by science and it beggared the imagination for most of us.  But people (most of them anyway), didn’t stand up and begin to argue passionately against these new findings.

And almost EVERYTHING you and I see around us in the world today is the product of science.   Telephones, electronics, plastics, microwaves, space shuttles, nylon and the list could go on and on for years.  It is hard to find much that we use that isn’t in some way or another the direct product of science and scientific research.   Not many people will stand up and claim that the chemistry that led to developing nylon is wrong.  Or that the laws describing voltage, current and resistance are wrong.

So what’s different about science’s findings about global climate change?

Well, you already said it.   It’s the money.  It’s the vested interests.  It’s what folks will stand to lose if the theories about CO2 and global climate change are true.  And it is big.  If this stuff is true, it means nothing less than that we have to simply reorganized how we do business on this Earth.  Almost everything about how most of us live is going to have to change some if we want to continue to live on this planet without turning it into a hell.

So, that’s a big big change that will result if we listen to what the scientists are saying.  It’s going to cost big oil/gas/coal billions of dollars.  It’s going to change the geopolitical balance between nations, it’s going to mean that ordinary folks like you and I and Joe Six-pack are all going to have to do things differently.

But nobody likes to lose money, nobody likes to lose political power and nobody likes to change their familiar and comfortable life-style.   Joe Six-pack doesn’t want to hear that his big two smoke-stack turbo diesel truck is bad for the planet and we can’t afford to have it running around any more.  The folks making money cutting down the Amazon rain forest don’t want to hear it.  The fishermen fishing the fish in the sea into extinction don’t want to hear it.   The folks buying cheap shit at Wal-Mart, don’t want to hear it.

And that brings these findings of the scientists right smack up against human nature.

And that human nature doesn’t want to change and it will begin to squirm and look for every reason and excuse it can to dodge the bullet and to avoid having to change, or lose money or whatever it is.

When the scientists decided that 70% of the entire universe was made of dark matter a few years ago, no one demonstrated in the streets or began to talk against it on the Rush Limbaugh show.   It didn’t get into anyone’s back pocket – so they didn’t care.

But CO2 and Global Climate Change is going to get into all our back pockets – big time.

Let me take you back and give you some history.   I learned what I’m going to tell you from a book entitled, Red Sky at Morning by Gustave Speth.

In the 1970’s, environmentalists in the U.S. were just beginning to push their efforts to get laws passed like the Clean Air Act and the Food and Drug Laws.  The public was mildly interested and industry was ignoring all of it.   Then Three Mile Island and a few other things all happened at about the same time and suddenly the public was very hot to support environmental protection laws.  The result was that a lot of laws about protecting the air and the water and such were all passed at once before the industry folks were really awake to what was happening.

Industry lost a lot of money because of all of these new laws and they vowed to never be asleep at the wheel again.

About 10 years later, in the 1980’s, the environmentalists began to realize that they could not protect the entire world by just passing good laws in the U.S.   They needed to expand their efforts and begin to fight for environmental protection laws that would be international in scope.  By the early 90’s the alarms were being sounded that we needed to do some things internationally or we, as a species, and as a planet, were going to have big problems.

But this time industry was not asleep.   They’d been burned once by not paying attention.   Now, every time an effort was mounted to increase environmental protection globally, industry looked at the proposed laws and if they could see that such a law was going to cost them big money, they mobilized to confuse people and to prevent the political will from developing to pass such a law.

This cat and mouse game has been going on for two decades now.   At first the scientists simply published the results of the scientific research in papers.  They trusted that people would be smart enough to see the writing on the wall.   But, industry confused people and confused the issues.  They published counter studies that seemed to show the opposite conclusions.

So scientists and environmental activists began to talk louder trying to get their messages and warnings out.  And industry fought back harder.  And the entire thing escalated up and up.

Most scientists now think that the entire “Global Climate Change is because of CO2” issue has been definitively proven over and over beyond the shadow of any doubt.   But the public doesn’t think that.   They are still deeply confused by the mis-information industry has been putting out for just that purpose – to confuse them and to therefore prevent political will from developing that could result in some real laws getting passed.

What’s going on in Copenhagen now is a great example.   Many people think that awareness of our environmental problems has finally gotten to the point where the world’s leaders might actually come together and try to do something real to prevent a major environmental and climate disaster.   And then, two weeks before the conference, the other side unleashes a major campaign to throw doubt on the scientific conclusions and to mess the entire conference up.

And, I fear, they are doing a pretty good job.   Frankly, I think we’re toast and I’ve thought so for a long time.   Human nature is just too predictable and to easily manipulated.   Those who want to convince the public that the climate science is wrong actually have a pretty easy time of it because Joe Six-pack and folks like him would prefer to believe that nothing’s going on because it is way easier than thinking about the fact that they might have to change their consumerist lifestyles.

So yeah, some folks are sounding like shrill Chicken Littles.  Why?  Because it is a damn desperate situation and the world is likely to go into the toilet in spite of the very best efforts of the environmentalists.  And they are worried about it.

After reading over what I’ve written here, I realize that I’ve only partially answered what you actually asked.  You asked for some balance on the question of how CO2 is processed by the environment.

There are a lot of answers to that because, as you can imagine, the world’s climate and biosphere is a wickedly complex system.   But, here are a few of the high points:

– The level of CO2 in the atmosphere hasn’t been this high in 6 million years.

– The current swift rise in the level of CO2 in the atmosphere is faster than anything we can see in the climate records back for 6 million years.

– This rise corresponds with the rise of industrial civilization.   It begins in the climate record just about the time industrialization began when the English started building factories in the 1840’s or so and it increases in the climate record in pace with the increasing rise in industrial production.

– The denialists say that the rise in CO2 is a natural thing and has nothing to do with the CO2 humans are putting into the air.   I find that an amazing idea.   It’s like saying, “I just tromped down on the gas pedal and now the car is going really fast.”   And then having someone tell you that it’s just a coincidence and that the gas pedal has nothing to do with the acceleration.  Yeah, right.

– Nature does have some ability to absorb excess CO2.  The ocean absorbs a lot of it.  But, it cannot keep up with the rate we’re adding it to the air.   And, as the ocean absorbs it, the water becomes more acidic.  As it becomes more acidic, it makes it harder for ocean animals that have shells to make their shells because the acidification interferes with their chemistry.  At some point, this rise in dissolved CO2 is really going to mess with some huge food chains in the ocean.

– Plants and trees like CO2 and use and absorb it.  To a point.  Add a little more CO2 and a little more heat and they thrive.    But, add a bit more and they begin to weaken and wilt and their ability to absorb CO2 lessens.   This is true for the majority of plants and trees.   There are some exceptions but they are a minority and what really matters is what the majority of the world’s plants and trees are likely to do.  And what they are likely to do it not good.

– Big coal has been yammering on for years about CO2 sequestration.  But, in spite of many big public relations splashes, no one yet has made a full scale carbon sequestration plant that works.   In the mean time, China is building one or more coal fired dirty power production plants a week!   Much of the public thinks “clean coal” is either a done deal or very close.   It truth, it is miles and mile off and maybe we’ll never have it.

– The problem is bigger that just how much CO2 we’re putting into the air.  That’s bad and we can see it ramping up.  But, it is causing other problems much as one fire creates others as the embers fly.

– The arctic ice is melting and as it does, the white snow and ice disappear and the darker sea and land underneath become visible.  The white reflected heat back into space.   The darker stuff being exposed absorbs it.  So there’s more heating going on because of this and it, in turn, causes more ice and snow to melt.  It is a positive feed back cycle and it is beginning to get up onto legs of its own.

– Glaciers all over the world, with very few exceptions, are melting.  The winter snow falls that used to stay in the mountains and then melt in the summer are going away and that’s going to have a huge impact on human beings.  The summer water that millions need to grow crops and survive is going away, soon.  We’re talking most of the west coast of South America, the Southwestern U.S., Northern India and a huge swath across Central China from east to west.  We’ve never seen anything like the disruption and starvation that will result.

Dave, I’ve been reading this stuff for years and this is just a part of what I’ve read.  Scientists have no reason to make this stuff up.  But, folks who make big big bucks by keeping the world running as it is now have a huge motivation to not see and react to the coming global climate changes.  These folks have a lot of money and they think that even if there are big problems, they will have to money to hang out in nice villas up in the Alps and where ever while the rest of use starve and fight it out in the streets.

All they have to do is keep us confused so we won’t shut their party down.

Got Gas?

Sunday, October 18th, 2009

– A good friend of mine sent me this article saying, “Interesting article on natural gas“.

– It is, indeed, an interesting article but I saw it in a different light than many perhaps do.

– My response to my friend:

D,

An interesting and potentially game-changing story, indeed.

But, it is a classic case of humanity’s inborn tendency to jump at the short term relief without fairly balancing it against the long-term consequences.

To see the consequences, I’d like to see someone make the assumption that ALL the fossil fuel we burn from here forward is this cleaner gas.   And, to be really fair, we can drop all considerations of the collateral damages associated with obtaining the gas that were mentioned in the article.

Just assume that the world will continue growing and producing and have more babies and all the rest of it for the next 20 to 50 years – all largely fueled by this gas.

The analysis should show what will happen to the CO2 levels in the atmosphere from consuming just this gas.  And then it should consider the consequences of this change in CO2 levels on global weather, ecosystems, environmental refugees, depleted glaciers and winter snow packs, increasing desertification, species die-offs and an entire host of follow-on consequences that will attend continued rising of global CO2 levels.

Short-term thinkers are enthusiastic about these new gas producing technologies because they allow us, for the moment, to avoid having to deal with the really tough long term questions regarding what we have to do to get into a sustainable long-term homeostatic balance with the planet’s ecosphere.

Long term, it’s really the only question that matters much.

Everything else is an avoidance or a denial that only take us further down the road wherein we do not solve this problem and cause a major crater in the Earth’s evolutionary history; killing many species, altering the weather for tens of thousands of years and killing the majority of the human beings alive and reducing the ones that survive to miserable circumstances.

Not an insignificant outcome – and all the more terrible because, difficult as it may be, we could avoid most of it if we had the grit and the will to do so.

Tiny particles pose threat: scientists

Friday, August 28th, 2009

– I’ve been beating this little drum for sometime now.   I think when we look back in the future on today’s science, this will be one of the big ‘gotchas’ we missed.

– I’ve written on this before here: , , , , and .

= = = = = = = = = = =

Tiny particles in consumer products sold in New Zealand and around the world pose health and environmental risks and need to be tracked, scientists say.

Amid growing worldwide concern about the potential effects of nanoparticles, Kiwi scientists, academics and officials want the Government to introduce a labelling system identifying nanomaterials used in products on supermarket shelves and to maintain a public database of nanoproducts.

Nanoparticles are about 1000 times smaller than the width of a human hair and are used in more than 800 consumer products, including cosmetics, sunblock, clothing, food, washing machines and refrigerators.

A report on the opportunities and drawbacks of nanotechnology has just been published by the Ministry of Research, Science and Technology. It lists more than 70 actions the Government should take.

Report editor and University of Canterbury physicist Simon Brown told The Press that apart from nanotechnology’s obvious advantages in the computer and electronics world, there were known and unknown hazards.

There was a strong sense the Government had yet to face up to nanotechnology.

Sizewell nuclear disaster averted by dirty laundry, says official report

Sunday, June 21st, 2009

Contractor noticed water from radioactive cooling pond that posed ‘significant risk to operators and public’

A nuclear leak, which could have caused a major disaster, was only averted by a chance decision to wash some dirty clothes, according to a newly obtained official report.

On the morning of Sunday 7 January 2007, one of the contractors working on decommissioning the Sizewell A nuclear power station on the Suffolk coast was in the laundry room when he noticed cooling water leaking on to the floor from the pond that holds the reactor’s highly radioactive spent nuclear fuel.

As much as 40,000 gallons of radioactive water spilled out of a 15ft long split in a pipe, some leaking into the North Sea. The pond water level had dropped by more than a foot (330mm) – yet none of the sophisticated alarms in the plant sounded in the main control room.

By the time of the next scheduled safety patrol, the pond level would have dipped far enough to expose the nuclear fuel rods – potentially causing them to overheat and catch fire sending a plume of radioactive contamination along the coastline.

The HM Nuclear Installation Inspectorate’s report of the incident, obtained under the Freedom of Information Act, said: “The pond could have been drained (it takes about 10 hours) before the required plant tour by an operator had taken place. In this worst-case scenario, if the exposed irradiated fuel caught fire it would result in an airborne off-site release.”

It concluded: “NII believes that there was significant risk that operators and even members of the public could have been harmed if there had not been fortunate and appropriate intervention of a contractor who just happened to be in the right plant area when things went wrong.”

American Chemistry Council: Balancing Trivia With Toxic Violence

Saturday, May 16th, 2009

It’s common knowledge that given a choice of two tasks, of varying impact, most people in the civilized world will choose to do the easiest, even if the outcome is of little or no importance. Given the choice of walking a mile to your destination, or getting in the car and driving a mile – regardless of the environmental and social impact of cars – most people will choose to drive. Or rather, “choose” to drive.

I put the word “choose” in quotes because it’s not really a choice at all; civilized society conspires to make the option that is of most benefit to the capital economy the most favourable “choice”, even if it means that the “choice” runs counter to what most people would do given a genuine freedom and an absence of persuasive factors (e.g. advertising, social engineering, lack of alternatives) that steer the individual in the direction of the best choice for the economy. Recycling is a serious offender, not because there is anything intrinsically bad about recycling most materials, but because it is presented by society as an environmental “choice”: you can choose to recycle and be “green” or you can choose not to recycle and not be green.

What other choice is there? What about choosing to do any number of things that are substantially more important than recycling; like reducing your primary consumption of goods, repairing what you already have, reusing what others have no need of, bartering or exchanging goods and services, or just giving stuff away because it means the recipients will buy less of that stuff new. And then there is not filling the skies with toxic gases; not pouring millions of gallons of effluent into seas and rivers; not garnishing the biosphere with a cocktail of persistent chemicals then leaving others to sort out the mess later.

Carbon Nanotubes: Innovative Technology Or Risk To Health Or Environment?

Tuesday, May 12th, 2009

– I’ve written before about my concerns on the nanotechnology they are gleefully rolling out into our environment.   :arrow:, :arrow:, ➡

== == == == == == == == == == ==

Carbon nanotubes have made a meteoric career in the past 15 years, even if their applications are still limited. Recent research results show that – apart from their favorable mechanical and electrical properties – they also have disadvantageous characteristics.

One aspect which has rarely been considered so far is now addressed by researchers of the research center Forschungszentrum Dresden-Rossendorf. “If the application of products and commodities containing carbon nanotubes will increase in the future, then there will be a higher probability for the tubes to get into the environment during their production, usage or disposal, to be distributed there, and to bind pollutants such as heavy metals on their way trough the environment”, says Harald Zaenker, scientist at the FZD.

Via water into the environment

An important way for carbon nanotubes of getting into the environment is the way via the water. In their original state, the flimsy carbon fibers with a diameter of less than 50 nanometers (1 nanometer = 1 millionth of a millimeter) are hardly water-soluble. At first glance, they should therefore not be mobile in groundwater, lakes etc., i.e. they should rapidly settle or deposit. However, carbon nanotubes are able to form colloidal solutions if their surface structure is changed. Changes in the surface structure can be brought about deliberately during the production of the tubes or can be induced by natural processes if the tubes are released into the environment.

A colloidal solution, unlike a true solution of water-soluble substances, is a solution in which the apparently dissolved substance is finely dispersed in the solvent forming tiny particles. These particles are still much bigger than the molecules of a dissolved substance in a true solution. As colloids, carbon nanotubes might be transported anywhere in environmental waters. It is known meanwhile that the tubes can even penetrate cell walls and, thus, might theoretically be able to enter also animal or human cells. In addition, changes in the surface structure of carbon nanotubes cause another effect: their capability to bind heavy metals is increased.

Russia to build floating Arctic nuclear stations

Environmentalists fear pollution risk as firms try to exploit ocean’s untapped oil and gas reserves

Russia is planning a fleet of floating and submersible nuclear power stations to exploit Arctic oil and gas reserves, causing widespread alarm among environmentalists.

A prototype floating nuclear power station being constructed at the SevMash shipyard in Severodvinsk is due to be completed next year. Agreement to build a further four was reached between the Russian state nuclear corporation, Rosatom, and the northern Siberian republic of Yakutiya in February.

The 70-megawatt plants, each of which would consist of two reactors on board giant steel platforms, would provide power to Gazprom, the oil firm which is also Russia’s biggest company. It would allow Gazprom to power drills needed to exploit some of the remotest oil and gas fields in the world in the Barents and Kara seas. The self-propelled vessels would store their own waste and fuel and would need to be serviced only once every 12 to 14 years.

In addition, designers are known to have developed submarine nuclear-powered drilling rigs that could allow eight wells to be drilled at a time.

Bellona, a leading Scandinavian environmental watchdog group, yesterday condemned the idea of using nuclear power to open the Arctic to oil, gas and mineral production.

“It is highly risky. The risk of a nuclear accident on a floating power plant is increased. The plants’ potential impact on the fragile Arctic environment through emissions of radioactivity and heat remains a major concern. If there is an accident, it would be impossible to handle,” said Igor Kudrik, a spokesman.

Environmentalists also fear that if additional radioactive waste is produced, it will be dumped into the sea. Russia has a long record of polluting the Arctic with radioactive waste. Countries including Britain have had to offer Russia billions of dollars to decommission more than 160 nuclear submarines, but at least 12 nuclear reactors are known to have been dumped, along with more than 5,000 containers of solid and liquid nuclear waste, on the northern coast and on the island of Novaya Zemlya.

‘Safe’ climate means ‘no to coal’

Saturday, May 2nd, 2009

About three-quarters of the world’s fossil fuel reserves must be left unused if society is to avoid dangerous climate change, scientists warn.

More than 100 nations support the goal of keeping temperature rise below 2C.

But the scientists say that without major curbs on fossil fuel use, 2C will probably be reached by 2050.

Writing in Nature, they say politicians should focus on limiting humanity’s total output of CO2 rather than setting a “safe” level for annual emissions.

The UN climate process focuses on stabilising annual emissions at a level that would avoid major climate impacts.

But this group of scientists says that the cumulative total provides a better measure of the likely temperature rise, and may present an easier target for policymakers.

“To avoid dangerous climate change, we will have to limit the total amount of carbon we inject into the atmosphere, not just the emission rate in any given year,” said Myles Allen from the physics department at Oxford University.

“Climate policy needs an exit strategy; as well as reducing carbon emissions now, we need a plan for phasing out net emissions entirely.”
