Like the Bermuda Triangle of the Sea

Wednesday, May 7th, 2008

 

“Strange Days on Planet Earth” series from the National Geographic channel previewed the North Pacific Gyre, a swirling clockwise vortex, of ten million square miles. We wonder where all the debris goes that gets into the water.  It ends up where it’s ashamedly known as the Great Pacific Garbage Patch. Among other things tons of plastic has accumulated here. Some argue plastics do eventually bio degrade, well, not so much. Plastic photodegrades, which means it gets smaller and thinner, and thinner until it is in micro pieces.

 

Most people are not aware of this gyre. Others know to avoid it’s swirling outer perimeter and the dead calm center. So many haven’t actually experienced the mess. In the series “Strange Days,” a boat decided to motor across the gyre to cut down on time on its way to another environmental study. It would only take a week to cross. But once the boat entered, the captain could not believe what he encountered day after day. He said it was literally a cesspool of large items and what appeared to be floating flakes. The captain decided to lower a skim for plankton that pretty much looks like a cheese cloth wind sock meant to gather plankton. What he gathered were small plastic particulates in the millions. According to Wikipedia: “These pieces, still polymers, eventually become individual molecules, which are still not easily digested.[1] Some plastics photodegrade into other pollutants.”

 

Birds and other mammals are feeding on this stuff. Birds feed it to their offspring. Industrial plastic pellets are washing up near shorelines also, and look like fish eggs. Baby albotross’ dead on the beach showed exposed stomachs filled with plastics of all kinds. There is more polymer in the N. Pacific Gyrate than there is plankton. According to Wickipedia: “Besides ingestion and entanglement of wildlife, the floating debris absorbs toxins in the water which, when ingested, are mistaken by the animals brain for estradiol, causing hormone disruption in the affected wildlife.” This is evidence of more hormone disruptors that affect the genetics of young life. We’re seeing gender bender fish, wait until we start finding gender bender birds and mammals. That’s food for thought. Right now we’re eating into this polluted animal chain, and will more than likely suffer the same consequences in the future if not already. So keep using and throwing out plastic of all kinds and keep saying man doesn’t have an affect on his environment and that recent rapid changes in climate are happening naturally. Sure.

Gender Bender Fish, Bisphenol A from Plastic, and Baby Bottles

Thursday, May 1st, 2008

As part of the “Strange Days on Planet Earth” by National Geographic that I watched on PBS, was a segment about compounds found in plastic like bisphenol A that leached into a Missouri Tributary, and into the fish and animals in a remote area. Bisphenol A acts like estrogen, and is an endocrine interrupter. It doesn’t take much for this stuff, 30 parts per trillion, to affect estrogen response in fish because they have an extremely sensitive system.

I went to find out more about this because I’ve already written about fish in N.Y. and recently the Potomac River in Washington that have both sexes, have changed gender, or are sexless due to estrogen discharged in the effluents of sewage treatment plants. When I watched this latest presentation about fish in Missouri that are altered by bisphenol A, I thought I would rummage around and found website after website from different places all over the country with gender bender fish.

There was even a study about perch in Michigan’s lakes on jestor @ http://www.jstor.org/pss/3435861. The article listed various endocrine disruptors present in the water like the estrogen from sewage plants but also bisphenol A. Read the article because it states “gonadal intersex was observed in male white perch collected from the Bay of Quinte (22-44%) and Lake St. Clair (45%), [] Intersex was not observed in hatchery-reared white perch or in white perch collected from an uncontaminated reference site (i.e., Deal Lake) in the United States.” So the lower Great Lakes are considered contaminated.

This does not bode well for our water systems. The “Strange Days” series continued about bisphenol A in plastic from which we eat and drink. It’s dangerous for our health. That’s why we’re being told lately not to microwave anything in a plastic container. As for baby bottles it’s really bad news.

The series stated that hormones control genetic programming in developmental stages of life, so babies are really affected by bisphenol A. Heating plastic baby bottle causes 10 times the amount of bisphenol A to leach out. They didn’t have to connect the dots any further. Do not use plastic baby bottles unless it’s documented they don’t contain bisphenol A.

Can excessive plankton buildup in the Arctic trigger same methane explosions as those off of Africa?

Thursday, May 1st, 2008

Yesterday I reported that NASA satellites are studying all types of changes on the earth. One of NASA’s studies whose results were on their website stated that:

Scientists from Stanford University in Palo Alto, Calif., set out to see what effect reduced sea ice cover would have on the organisms that comprise the base of the Arctic marine food web, the single-celled floating algae called phytoplankton. Because these photosynthetic organisms rely on the sun to meet their energy demands, reduced Arctic sea ice cover means an increase in the amount of open water habitat suitable for algal growth. Thus, their abundance is expected to increase.

Not surprisingly, the scientists found that the growth of phytoplankton has indeed increased markedly in concert with the rapid reduction in sea ice cover over the last five years. However, they were surprised to find that this growth did not take place in the areas of the Arctic where we expected it. The researchers anticipated that areas experiencing the most dramatic loss of sea ice would show the largest increase in algal growth. However this was not the case. Algal growth did indeed rise in newly ice-free areas, but only accounted for about one third of the total Arctic increase. The majority of the increase in algal growth (70 percent) was observed in the shallow waters that ring the Arctic Ocean. In these areas, algal growth rates increased because the sea ice in these areas, algal growth rates increased because the sea ice cover was melting sooner and freezing later in the year giving the algae increasingly more time to grow.

This was nine year study using all types of satellite imagery including and MRI Spectroradiometer to compare ocean color and temperature relative to sea ice melt that was also assessed.

I read a lot of things and certain words like phytoplankton buildup tweaked my curiosity as to the difference between phytoplankton and plankton. Phytoplankton is the autotrophic component of plankton. According to Wikipedia an “autotroph is an organism that produces complex organic compounds from simple inorganic molecules using energy from light or inorganic chemical reactions. Another article I found at:

http://www.futurepundit.com/archives/002481.html didn’t differentiate between phytoplankton and plankton.

This does not bode well at all in my mind because of the blog I just wrote about explosions of methane gas into the atmosphere that are growing in size to that of meters in the ocean waters off of Namibia. If all of this phytoplankton is rapidly spreading in the shallow waters that ring the Arctic Ocean, and there are not enough fish or marine mammals in that region to eat the excess plankton (phytoplankton), doesn’t it stand to reason that this Arctic phytoplankton will go the way of plankton near Namibia? In other words, it will die and rot, creating hydrogen sulfide pockets. All that is needed is high pressure from a storm on the ocean’s surface to affect the pressure on the ocean bottom in these particularly shallow waters around the Arctic and an eruption might occur. These are the same eruptions happening off of Namibia. I realize that scientists claim these explosions are not likely to take place because of the constant churning of the ocean floor. But then there is Namibia. Explain that?

http://www.blogsmonroe.com/world/2008/04/24/mankind-contributes-to-global-warming-through-fish/

Scary stuff since the first global warming event 40 million years ago was from methane gas eruptions. The earth was eventually scorched. This just shows how delicately balanced our world really is. We fish too much, or disrupt certain species by changing habitat drastically, and something else is thrown out of kilter like phytoplankton, something so small we don’t really see it except for greenish colored water. It’s something so small, yet it can eventually kill us.

The Chicken Little Crowd is Getting Bigger and With More Clout

Monday, April 28th, 2008

I read Mitch Albom’s column in the Free Press this past Sunday, and although I agree with him, I think it was well, um, a little bit dated. His perception that environmentalists are a league of people still derided as Chicken Littles is a little off. As long as I’ve been writing this blog, I think maybe I’ve been called a Chicken Little twice. I had one opponent that appeared to be a drinker going off into raves eventually calling me a cur so as to not get axed from the website for calling me something worse. But that was long ago. Another opponent eventually came to terms with the fact that on a lot of levels we are simpatico. We agreed that we do indeed create trash and should be cleaning up after ourselves, whether or not it does or does not contribute to global warming. Isn’t this moment of agreement in the environmental argument all that’s needed? Because cleaning up after ourselves is the first step to realizing just how much garbage we actually create, which should logically lead to more conservation efforts regardless of global warming.

In this light, how the pro-environmental argument is presented seems to make a heck of a lot of difference. Finding common ground brings people to agreement faster, and that’s what seems to be happening. Unlike Albom, I’m seeing a huge surge of environmentalism on TV and the Internet lately. My 85-year old mother pointed it out to me about 2 weeks ago. I paid closer attention after that and she’s right. There are all types of commercials on TV that are telling people to buy in bulk, don’t shampoo their hair every day, you know insidious mantra that eventually gets an entire population moving toward conservation without knowing it. Admit it. We’re herded more times than not and industry with the help of the media is like the rancher.

I blogged about industry moving the green market quite a while back. Industry’s push to go “green” is getting increasingly stronger because they can’t afford high energy costs either. GE can hardly keep up with the demand for its industrial wind turbines. Green rooftops are appearing on city buildings everywhere thanks to newly formed environmental organizations like Green Roofs for Healthy Cities. And just look up companies growing in leaps and bounds like Sun Edison, who provides an affordable way for industry to benefit from rooftop solar panels, that is, if they aren’t already planted green. Retail giant Wal-Mart starting moving to go green, and now companies like SC Johnson are looking to supply those big stores with their “totally” green .products. Even Conoco Philips (Big Oil) threw in the towel, and joined Tyson Chicken to create biofuel from chicken fat at no real profit, just because it’s the right thing to do for the environment. And when moguls like Ted Turner make statements that it’s absolute suicide to continue to pollute and consume the way we do, well, try calling terrible Ted a “CL.”

I’ve lost count of all the home improvement shows that tout “green,” as well as, media outlets like PBS, Discovery, Science, and National Geographic channels that consistently show the latest findings and discoveries regarding the environment and man. I’ve even watched Canadian TV like “The Outsider,” or “The Fifth Estate” air documentaries about U.S. government cover ups of scientific reports relative to global warming. I’m seeing more and more green shows coming out of Canada now. And I can’t say enough for organizations listed as links on my blog like EarthJustice, The Sierra Club, Defenders of Wildlife, Union of Concerned Scientists, and many others that don’t think twice to take on the U.S. Government or anyone else over the environment and wildlife. While we sleep, or go about our usual day, these guys are out on cold oceans, at the edge of public forests, in congress, and everywhere they need to be to stop bad things from happening to our world and everything in it.

But best of all when I see Nancy Pelosi and Newt Gingrich in a commercial urging citizens to contact congress to push ahead to embrace environmentalism, it’s a clear indication that forces are looking to gather against the old energy lobbyists and the spin machine. This was topped off last week when Henry Waxman, Chairman of the Committee for Oversight and Reform, sent a letter to EPA Administrator Johnson, that he need be prepared to testify regarding the recently released Union of Concerned Scientists Report documenting extensive and widespread political interference with the work of scientists at EPA. Yes!!!

Add to that the U.S. Supreme Court’s ruling that the EPA should be regulating CO2 emissions from autos as part of the Clean Air Act, and the U.S. Court of Appeals vacating the EPA’s “Clean Air Mercury Rule,” literally throwing out the EPA’s cap and trade system for mercury, and demanding the EPA set new standards for the coal burning industry within two years. Concurrently, it also vacated the EPA’s “Incinerator Rule.” This bodes exceptionally well for the Chicken Little movement.

The timing is uncanny, but unlike Mr. Albom’s perception of environmental efforts, this past Sunday, for the first time in a very long time, I was optimistic about environmentalism, my faith in America restored. After researching the onslaught against our parks, our air, our water, animals, and their habitat for so long by the Bush/Cheney administration, I finally sensed a real, hardy shove back by the other powers that be, which is American industry and ingenuity. They don’t seem to suffer low self-esteem as a “Chicken Little” crowd at all. Had Mitch written about the “CL” complex a year ago I might have wholeheartedly agreed. But now, all I see is the “greening” of America, like it or not. As for “Chicken Little” calling, sticks and stones…

Mankind Contributes to Global Warming Through Fish

Thursday, April 24th, 2008

I couldn’t post a blog last night because I lost my dial tone again. It just came back on so I’m getting this out there as fast as I can. I couldn’t research what I wanted to blog about and maybe that’s a good thing because I caught an absolutely fantastic show on WGTE, Toledo Public TV last night as part of their Strange Days on Planet Earth series. Ed Norton narrated current findings relative to global warming that are directly tied to of all things fish and mankind. Like he said no one would ever consider fish as heroes of the global warming battle but after last night’s presentation the realization of how man is so intimately connected to everything on earth, that every little thing we do, every little thing we eat like a sardine, affects us and sometimes in very bad ways that only adds to global warming and loss of more food.

What was showcased is the latest correlation between man and global warming concerns fish. Did you know that Namibia besides being the birthplace of Angelina Jolie and Brad Pitt’s baby is also home to one of the world’s richest fisheries? At least Namibia was rich with fish 40 years ago, where millions of tons of fish were processed per year and sold worldwide.
 
Namibia is one of the most productive ocean systems in the world because it enjoys almost constant ocean winds, which churn up nutrients like plankton from the bottom. Sardines love plankton and swarmed the area in the millions. But man over fished the sardines years ago and although Namibia has made a concentrated effort to recover their fish populations, it’s just not happening. Fleets of fishing boats from Europe and other far away places invaded that space and harvested, and harvested, ten million sardines in one month’s time sometimes, without enforced regulations to stifle the pillaging.

So what about sardines you say? As part of another delicate ecosystem that has been disrupted by mankind, the sardine is necessary to insure the plankton does not build up on the ocean floor. Rotting plankton has a very detrimental effect.  Hydrogen sulfide and methane production is the by-product of rotting plankton. Sulfur is that rotten egg smelling gas.

As a result of over fishing sardines, Namibia’s coastline now boasts a strange shift in ocean color on a regular basis. Some call it lemonade, or a whitish ethereal color appears while the horrible stench of rotten eggs is emitted, and then unimaginable amounts of dead fish float up and line the shoreline. With all the over-fishing in our oceans today, we do not need this additional kill off of fish. It’s creating a cycle where we’re going to end up with no fish at all.

Three people figured out what’s happening in Namibia. A marine biologist, Brownen Currie, a satellite expert Scarla Weeks, and an oceanographer Andrew Bakun figured out that deep-sea eruptions were taking place and emitting hydrogen sulfide. Bakun found that deep sea eruptions coincided with desert rain, that atmospheric storms that pass over the ocean’s surface cause pressure on top that translates to pressure at the bottom where the buildup of hydrogen sulfide and methane lay. Eruptions on the ocean floor take place releasing millions of bubbles of the two gases. As methane rises to the surface it expands and becomes explosive.

Experts have known about these eruptions for a while and figured they were isolated incidents, but when Scarla Weeks, a satellite expert became involved a whole other scenario surfaced. From satellite images in space these eruptions were shown to be increasingly more virulent, and are occurring back to back, growing out of control into huge events covering hundreds of kilometers over the ocean.

This is where my eyes bugged out. I wrote a blog about a CO2 explosion at the bottom of a lake in Africa, which resulted in a cloud of gas belching into the night and traveling miles to kill 1700 people. At first, it was thought to be a methane gas explosion like those happening off of Namibia. Then I remembered writing a blog about the first global warming event some 40 million years ago that incinerated the earth. It was caused by a ˝ degree in temperature change over a longer period of time than we’re experiencing now. It happened because of constant methane eruptions on the ocean floor from an earth that was still forming.  The atmosphere eventually filled with methane, which is twenty six times more effective at trapping heat than carbon dioxide, and the earth fried.

Scientists have always thought that it was impossible for methane or carbon dioxide to build up like that again on the ocean floor due to the constant movement of water. Wrong again. It seems like what we’re facing now is totally new territory. But there are still quite a few obstinate people who will not see that humans are affecting the earth in a myriad of ways that is upsetting the intricate balance of all living things. This is just one of the ways we’ve impacted the earth and helped global warming along. I remember someone I talked to about environmental events brushing off the idea that an increase in earthquakes is tied to global warming. Why not? Now that we know atmospheric pressure on the surface of seawater affects pressure at the bottom of the sea, it’s quite possible that atmospheric pressure can affect pressure below the earth’s surface just as easily, and there are a lot more earthquakes happening lately.

The idea of eating fish because it is healthy for us is starting to resemble the idea of drinking bottled water. We do it for our own health but do not realize the affects of those actions, that it hurts the earth to toss that plastic in a trash dump or along the roadside, every bit as much as over harvesting even the smallest fish. Without strict fishing regulations, new ways of farming fish, (more about that mess in another blog), and a quick attitude change by the human population to conserve, it doesn’t appear there will be enough in the wild to sustain mankind worldwide.

Watch “A Man Among Wolves” at 10:00 Tonight, Jan. 16, National Geographic Channel

Wednesday, January 16th, 2008

This is a very good documentary about wolves by researcher Shaun Ellis and also a good tribute to “Wolf Moon” month of January. Find out more about wolves and why we should stop the eradication of this species once and for all. A majority of people have spoken, but legislators, especially in Alaska, continue the sportless killing by helicopter and plane.

 Shaun Ellis doesn’t recite a documentary at you, he lives with the wolves. It’s good. Watch it. Learn.

All the Power We Need From What Looks Like a Satellite Dish?

Wednesday, January 16th, 2008

I caught the end of a program on the Science Channel tonight that featured Stirling Energy Technologies. Stirling has been around since the 80’s relative to alternative energy sources. Stirling is not selling retail to the public on an individual basis yet, but considering I have a large satellite dish out here in the boonies I would have no problem owning a solar dish in the future.

The FAQ page for Stirling describes: 

Our Solar Dish Stirling system is shaped much like large satellite dishes (approximately 37’ in diameter) and covered with curved mirrors. These solar dishes are programmed to always face the sun and focus that energy on a collector in much the same way that a satellite dish focuses radio waves on a tuner. This collector is connected to a Stirling engine, which uses the thermal power generated by the focused solar energy to heat liquid hydrogen in a closed-loop system. The expanding hydrogen gas creates a pressure wave on the pistons of the Stirling engine, which spins an electric motor creating electricity with no fuel cost or pollution. This technology is referred to as solar thermal or concentrating solar power.

The company also says that at a “power plant producing 1,000 MW, the cost per kWh would be less than ten cents,” and “[o]ne dish on an annual basis can produce 55,000-60,000 kWh of electricity. This is equivalent to the total energy required for 8-10 homes in the U.S.” ChaChing!

Stirling may save the Western part of our country in the future. Right now Stirling is planning a solar field 5 miles square in the desert that will supply the entire city of San Diego with electricity. Of course as more of this type of technology is utilized, the more the engineers can improve and modify, modify, modify. Remember computers back in the 70’s? I used to do keypunch and then worked on a desktop computer in U of M hospital’s personnel dept. The mainframe to those computers back then took up a whole room. We had to type the info on forms with 7 carbon copies first, then input the data too because we couldn’t trust that the system wouldn’t go down and dump everything. The miracle of innovation, and modification is apparent as I type this on my little laptop that I can take anywhere and doesn’t even require a mouse. See what I mean?

The sooner we unleash all the technology that is out there to see what we actually can come up with, the sooner it gets modified down to convenient personal size. Right now it would take 20,000 dishes to equal a coalburner or nuke plant. But with future innovation and modification in no time we could see that number down to hundreds as the size of the equipment is reduced. Better yet our own personal dish, and mini power station no bigger than a small boiler that produces everything we need with absolutely no fuel used or pollution produced to keep us nice and cool as the sun sears on.  Am I taking it too far? I don’t think so.

Watch Larry King with Jack Hanna Tonight on CNN

Tuesday, January 1st, 2008

This should be a pretty good show since Jack is bringing some rare and threatened species of animals on the set. And there should be a lot of good information about what is disappearing from the planet due to climate change. Jack is passionate about animals and so am I. I really don’t want to be the generation that remembers animals in the wild like the old Tarzan flicks because the animals no longer exist anywhere.

January is the Month of the Wolf Moon According to Native American Lore

Tuesday, January 1st, 2008

So is this how we celebrate the wolf in January 2008 America–slaughtering them as a species? President George Bush, Vice President Cheney, Secy. of the Interior Dirk Kempthorne, (former Gov. of Idaho), current Gov. Butch Otter of Idaho, and Gov. Dave Freudenthal of Wyoming, as well as, Gov. Palin of Alaska are advancing their plans to skip the threatened and endangered species list and eradicate wolves by aerial helicopter, plane, snaring, etc., in Idaho and Wyoming. Alaska is already obliterating wolves by aerial hunting there. Gov. Palin just wants to keep the carnage going.  I find it interesting that while Gov. of Idaho Kempthorne pushed to get state control over wolves and now he is in charge of Dept. of the Interior overseeing this latest wolf assault.

http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/970314a.html

While Kempthorne heads the Dept. of Interior, the U.S. Dept. of Agriculture’s (USDA) National Research Center has current reports that wolves have restored much balance in the wild, keeping coyote populations down. Another 3-year study radio collared wolves in packs whose habitats surrounded the perimeter of cattle ranches. The wolves constantly crossed through cattle herds at night. In 3 years, wolves killed only 8 cattle. The National Geographic Channel aired a segment about Yellowstone’s wolves being a great success for the environment there. Why the rush to kill wolves after allowing them to flourish, especially if they are maintaining a balance among other predators?

This concept of wolf slaughter via aerial planes and helicopters is a hideous irony considering the American wolf is a major and honorable component in Native American history. Native Americans like the Cheyenne, Sioux, and Arapahoe admired wolves for the way they “operated in packs, caring for each other and sharing food, as well as the strength, endurance and hunting skills displayed by the Native American wolf. These were the same qualities that would help to ensure the survival of the tribe, qualities worthy of emulating.” http://www.native-languages.org/composition/native-american-wolf.html.

Running an animal to exhaustion from a helicopter or a plane to shoot it with sighted high-powered rifles from above isn’t honorable hunting skills. It’s sacrilegious that our government officials are willing to hunt an animal in such a cowardly manner while Native Americans revere the animal for its hunting skills. Wolves are not rats. Many Native American Tribes believed wolves to be teachers and called their scouts “wolves” that were brave enough to be the first to venture out and bring their experiences back to the tribe as wolves do for their pack. Right now many Christian Americans embrace creationist theory for their origins. Native Americans have their own creationist theory that includes wolves, “… the Medicine Wheel atop Medicine Mountain in the Bighorns, [] the Massaum Ceremony, “the medicine dance of the ancients,” a beautiful and integral part of traditional Cheyenne culture in which the wolf, and the “Wolf’s Lodge,” is essential to creation, to life, and renewal in the spiritual and physical,” http://www.infohub.com/vacation_packages/3367.html.

And so here we are in 2008 allowing an already dubious administration to slaughter an icon of our heritage by cowardly if not sadistic means while we cry to other nations to stop clubbing seals, hooking dolphins, and killing whales for research.  This administration attempts to evoke a sense of patriotism in everything else they do; yet they overlook the wolf. Look at some of the names of the leaders of some of the greatest tribes that once ruled America.

“Little Wolf was the Native American chief of northern Cheyenne. Little Wolf, who led a military society called the Bowstring Soldiers, was a leader in the Northern Plains wars. He and Sioux and Arapaho warriors fought together in the War for the Bozeman Trail, which was also known as Red Cloud’s War, from 1866 to 1868. Little Wolf was a signer of the Fort Laramie Treaty in 1868,” http://student.britannica.com/comptons/article-9312204?

Among the signers of the Laramie Treaty were many native chiefs whose names included wolf: Of the Ogallalah band of Sioux chiefs there was High Wolf and Big Wolf Foot, of the Uncpapa band of Sioux chiefs was Wolf Necklace, and of the Arapahoe chiefs there was Spotted Wolf, Big Wolf, Wolf Mocassin, and Wolf Chief.
http://digital.library.okstate.edu/Kappler/Vol2/treaties/sio0998.htm.

There are many citizens interested in Native American culture that should embrace the seriousness of what is being proposed for wolf populations in these particular states. Out of heritage, patriotism, and humaneness for America’s wildlife, call or contact your congress people to stop this type of eradication process for living things once and for all. Contact the media for more coverage about wolves and their future in America.
