ENGINEERING SALMON CONSUMERS

“The main concern addressed was whether the genetically engineered salmon could escape and establish themselves in the wild, with detrimental environmental consequences. The larger salmon, for instance, could conceivably outcompete wild Atlantic salmon for food or mates. The agency said the chance this would happen was ‘extremely remote.’ It said the salmon would be raised in inland tanks with multiple barriers to escape. Even if some fish did escape, the nearby bodies of water would be too hot or salty for their survival. And reproduction would be unlikely because the fish would be sterilized, though the sterilization technique is not foolproof.” Damn, I guess they're right; I don't see a flaw in their reasoning, not even a loophole the size of a salmon/eel gene switch. It's as safe and sure a thing as so many other government promises. Maybe even better than those decades of Fukushima reactor assurances, starting back in the 1970s and going on until March of last year, when they somehow turned into actual lies. Odds must be, jeez, like one in-- some other number! And growth hormone year round, too! What could go wrong there? Wonder what kind of labfood they're fed in those tanks. Unevolved, human-made and bred fish naturally aren't very smart. I suppose these would have to taste pretty close to salmon. But most folks won't know what they're eating.

Why genetically engineered food is dangerous:
New report by genetic engineers


One of the report's authors, Dr Michael Antoniou of King's College London School of Medicine in the UK, uses genetic engineering for medical applications but warns against its use in developing crops for human food and animal feed.
Dr Antoniou said: "GM crops are promoted on the basis of ambitious claims – that they are safe to eat, environmentally beneficial, increase yields, reduce reliance on pesticides, and can help solve world hunger.
I felt what was needed was a collation of the evidence that addresses the technology from a scientific point of view.
Research studies show that genetically modified crops have harmful effects on laboratory animals in feeding trials and on the environment during cultivation. They have increased the use of pesticides and have failed to increase yields. Our report concludes that there are safer and more effective alternatives to meeting the world’s food needs."

Another author of the report, Dr John Fagan, is a former genetic engineer who in 1994 returned to the National Institutes of Health $614,000 in grant money due to concerns about the safety and ethics of the technology. He subsequently founded a GMO testing company.
Dr Fagan said: "Crop genetic engineering as practiced today is a crude, imprecise, and outmoded technology. It can create unexpected toxins or allergens in foods and affect their nutritional value. Recent advances point to better ways of using our knowledge of genomics to improve food crops, that do not involve GM.
Over 75% of all GM crops are engineered to tolerate being sprayed with herbicide. This has led to the spread of herbicide-resistant superweeds and has resulted in massively increased exposure of farmers and communities to these toxic chemicals. Epidemiological studies suggest a link between herbicide use and birth defects and cancer.
These findings fundamentally challenge the utility and safety of GM crops, but the biotech industry uses its influence to block research by independent scientists and uses its powerful PR machine to discredit independent scientists whose findings challenge this approach."

The third author of the report, Claire Robinson, research director of Earth Open Source, said, "The GM industry is trying to change our food supply in far-reaching and potentially dangerous ways. We all need to inform ourselves about what is going on and ensure that we – not biotechnology companies – keep control of our food system and crop seeds.
We hope our report will contribute to a broader understanding of GM crops and the sustainable alternatives that are already working successfully for farmers and communities."
