Prozac Pee and other Pharma waste makes Fish: Anxious, anti-social, aggressive, etc.



Prozac in Drinking Water / Prozac in Streams Hurt Frogs fish / Newborns suffer Withdrawal

The earlier video I refer to in this one is Prozac Residues in Fish. Researchers have also found evidence of Prozac levels in Poultry Products. Despite the contaminants, tap water is still likely better than bottled.
An article in the UK Observer–”Stay calm everyone, there’s Prozac in the drinking water” (below) — reports that British environmentalists are calling for an “urgent investigation into the revelations, describing the build-up of the antidepressant [Prozac] as ‘hidden mass medication’.
The article was forwarded to me by at least 12 concerned, knowledgeable people from the UK and US–their concern is justified. The UK Environment Agency has found that Prozac is building up both in river systems and groundwater used for drinking supplies. This is a direct result of the inordinately high quantity of antidepressants consumed and excreted into the environment.
In 2002, the U.S. Geological Survey tested 139 rivers in 30 states and found that 80 percent of streams sampled by showed evidence of drugs, hormones, steroids and personal care products such as soaps and perfumes.
In October, 2003, US scientists reported that Prozac and other pharmaceuticals were polluting US streams and affecting the development of fish and other wild life. According to the National Center for Health Statistics at the CDC, more than 61 million prescriptions for anti-depressants were prescribed by U.S. doctors in 2001. As pointed out, because prescriptions like anti-depressants are for chronic conditions, patients often take them for months and years at a time, making them more likely to build up in wastewater
CNN reported: “Researchers are working on several fronts to determine how big the problem is and just what short- and long-term ecological effects there might be on wildlife. Bryan Brooks, a toxicologist at Baylor University in Texas, discovered evidence of Prozac, an anti-depressant, in the brains, livers, and muscles of bluegill, caught downstream from the Pecan Creek Water Reclamation Plant in Denton, Texas, near Dallas”
Marsha Black, an aquatic toxicologist at the University of Georgia found that low levels of common anti-depressants, including Prozac, Zoloft, Paxil and Celexa, cause development problems in fish, and metamorphosis delays in frogs.

Fish on Prozac: Anxious, anti-social, aggressive

When fish swim in waters tainted with antidepressant drugs, they become anxious, anti-social and sometimes even homicidal. New research has found that the pharmaceuticals, which are frequently showing up in U.S. streams, can alter genes responsible for building fish brains and controlling their behavior. Antidepressants are the most commonly prescribed medications in the United States; about 250 million prescriptions are filled every year. And they also are the highest-documented drugs contaminating waterways, which has experts worried about fish. “At high doses we expect brain changes,” said scientist Rebecca Klaper. “But we saw the gene expression changes and then behavioral changes at doses that we consider environmentally relevant.” Male minnows exposed to a small dose of Prozac in laboratories ignored females and took more time capturing prey. When the dose was increased, but still at levels found in some wastewater, males became aggressive, killing females in some cases.

Pharmaceutical Waste: Why Is It An Issue Now? 

When fish swim in waters tainted with antidepressant drugs, they become anxious, anti-social and sometimes even homicidal.
New research has found that the pharmaceuticals, which are frequently showing up in U.S. streams, can alter genes responsible for building fish brains and controlling their behavior.
Antidepressants are the most commonly prescribed medications in the United States; about 250 million prescriptions are filled every year. And they also are the highest-documented drugs contaminating waterways, which has experts worried about fish. Traces of the drugs typically get into streams when people excrete them, then sewage treatment plants discharge the effluent.
Exposure to fluoxetine, known by the trade name Prozac, had a bizarre effect on male fathead minnows, according to new, unpublished researchby scientists at the University of Wisconsin-Milwaukee.
Male minnows exposed to a small dose of the drug in laboratories ignored females. They spent more time under a tile, so their reproduction decreased and they took more time capturing prey, according to Rebecca Klaper, a professor of freshwater sciences who spoke about her findings at a Society of Environmental Toxicology and Chemistry conference last fall. Klaper said the doses of Prozac added to the fishes’ water were “very low concentrations,” 1 part per billion, which is found in some wastewater discharged into streams.
When the dose was increased, but still at levels found in some wastewater, females produced fewer eggs and males became aggressive, killing females in some cases, Klaper said at the conference.
The drugs seem to cause these behavioral problems by scrambling how genes in the fish brains are expressed, or turned on and off. The minnows were exposed when they were a couple of months old and still developing.  >>MORE<<

1914 Germany Afrikaner farmer Agreement

thank you Etienne 
translated from Afrikaner to EnglishTo all the people of the white race all over the world, most of all to the German nation: This is an important agreement Concerning the South African Boer people and the German nation. It has to do with an agreement between the Boer rebellion and the German troops in Southwest Africa. The Boer rebellion were lead by leaders of the Afrikaaner nation (General Manie Maritz, General SG Maritz, General Koss Delarey) and who’ll be fought against the English in the Second Anglo-Boer war from 1899 to 1902, where the Afrikaaner nation under hun president In Paul Kruger ulcers completely humiliated by the English when ze ulcers forced to sign the Treaty of Vereeniging in 1902. The atrocities committed against the Boers in the Concentration camps ulcers horriffic to say the least, and at least 30 000 Boer women and Children Were driven from hun farms Which Were torched under Lord Kitchener’s Scorched Earth policies. The attached files are an ima…

Hardcore Gangs Hit Ohio Suburbs GANGS IN THE ’BURBS
Subversive element creeping beyond Columbus’ borders
Last year, Westerville North High School suspended two students who flashed MS-13 hand signs and drew gang insignia during an English-asa-second-language class. MS-13, or Mara Salvatrucha, is a notoriously violent street gang with roots in Los Angeles. It was formed by immigrants from El Salvador.

Gang crime isn’t nearly as serious or common in the suburbs as in some Columbus neighborhoods, but suburban schools and police departments are increasingly on watch.
"It’s not so centralized in the inner city as it used to be," said Pat Brooks, a veteran Columbus police gang unit officer.

Suburban police call Brooks and his colleagues when they suspect gang activity in their jurisdictions.

Most of the crack dealers in Reynoldsburg are gang members who live in Columbus, said Tye Downard, a Reynoldsburg police narcotics detective.

They go there to make mor…
