Related: About this forumNeil deGrasse Tyson on GMO food!
Cosmos host Neil deGrasse Tyson takes down the anti-GMO argument swiftly and deftly, in a way that only he can.
here has been a considerable amount of discussion and debate regarding the safety of genetically modified food. Though the topic has been researched over and over again, there isnt evidence that eating conventional produce will cause disease, despite whatever the scientifically-illiterate Food Babe has to say. In fact, over 2000 studies have found GM food to be perfectly safe. Genetic modification is simply a tool, and like all tools, it's how you use it that matters.

(27,137 posts)- I would have thought that a ''scientist'' would know better than to spout off on a subject with which s/he was not sufficiently qualified to make pronunciations upon regarding GMOs and limit his/her comments to his/her area of expertise. Which in his case, includes astrophysics but does not include GMOs nor the growing food for public consumption of any kind.
Abstract
Our previous studies have demonstrated that stable microRNAs (miRNAs) in mammalian serum and plasma are actively secreted from tissues and cells and can serve as a novel class of biomarkers for diseases, and act as signaling molecules in intercellular communication. Here, we report the surprising finding that exogenous plant miRNAs are present in the sera and tissues of various animals and that these exogenous plant miRNAs are primarily acquired orally, through food intake. MIR168a is abundant in rice and is one of the most highly enriched exogenous plant miRNAs in the sera of Chinese subjects. Functional studies in vitro and in vivo demonstrated that MIR168a could bind to the human/mouse low-density lipoprotein receptor adapter protein 1 (LDLRAP1) mRNA, inhibit LDLRAP1 expression in liver, and consequently decrease LDL removal from mouse plasma. These findings demonstrate that exogenous plant miRNAs in food can regulate the expression of target genes in mammals.
CELL RESEARCH: Full Study
"Our study contradicts Monsanto conclusions because Monsanto systematically neglects significant health effects in mammals that are different in males and females eating GMO's, or not proportional to the dose. This is a very serious mistake, dramatic for public health. This is the major conclusion revealed by our work, the only careful reanalysis of Monsanto crude statistical data."
Other Problems With Monsanto's Conclusions
When testing for drug or pesticide safety, the standard protocol is to use three mammalian species. The subject studies only used rats, yet won GMO approval in more than a dozen nations.
Chronic problems are rarely discovered in 90 days; most often such tests run for up to two years. Tests "lasting longer than three months give more chances to reveal metabolic, nervous, immune, hormonal or cancer diseases," wrote Seralini, et al, in their Doull rebuttal. [See "How Subchronic and Chronic Health Effects Can Be Neglected for GMO's, Pesticides or Chemicals." IJBS; 2009; 5(5):438-443.]
Further, Monsanto's analysis compared unrelated feeding groups, muddying the results. The June 2009 rebuttal explains, "In order to isolate the effect of the GM transformation process from other variables, it is only valid to compare the GMO with its isogenic non-GM equivalent."
The researchers conclude that the raw data from all three GMO studies reveal novel pesticide residues will be present in food and feed and may pose grave health risks to those consuming them.

"Shockley argued that the higher rate of reproduction among the less intelligent was having a dysgenic effect, and that a drop in average intelligence would ultimately lead to a decline in civilization. Shockley advocated that the scientific community should seriously investigate questions of heredity, intelligence, and demographic trends, and suggest policy changes if he was proven right.

(716 posts)Wow, Tyson confuses selective breeding with the genetic roulette that ignores the interaction of genes in living organisms, and the significance of exotic proteins. He is apparently unaware of the current BT and glyphosate problems, as well.
And it's alarming how many people trust short term testing to clear something for long term use; if that was good enough, we'd still have lead pipes, lead in house-paint, and leaded gasoline; not to mention asbestos.
The David Suzuki narrated film is quite good, thank you!
His daughter Severn Cullis-Suzuki has spoken wonderfully on these issues for her generation as well (as she still does), when she spoke at the UN Earth Summit in 1992:

(36,286 posts)genes already present in a population is the same as inserting new genes. For example, say I start with a population of rabbits, some long haired and some short haired. I can choose to breed long haired rabbits to long haired rabbits until I can be fairly certain that that given line contains only the genes for long hair. That's somewhat different from inserting a gene to give my long haired rabbits green fur that glows in the dark!
He does not address the problem that when plants are designed manufacture Bt toxins, the target insect populations are more likely to develop resistance to those toxins. Nor does he address the question of our long term exposure to those toxins.
http://en.wikipedia.org/wiki/Genetically_modified_maize
He does not address the problem of keeping the new genes confined to particular plants, so we are already seeing Round up resistant weeds.
https://www.extension.purdue.edu/extmedia/GWC/GWC-1.pdf
He does not address the problem of modified animals getting loose and perhaps driving other animals to extinction.
http://en.wikipedia.org/wiki/AquAdvantage_salmon
He does not address the issue of mono cropping and its effect on the entire environment including the soil base. Somehow, the use of GMO techniques is considered "scientific", but organic techniques developed and evaluated using the scientific method are not. Technology is not the same ting as science.
http://www.fao.org/docrep/016/ap563e/ap563e.pdf
Most of all, he ignores the many times "science" has brought us something new and wonderful that turned out later not to be so wonderful. It took most of the 20th century to understand the hazards of exposure to radiation from various sources such as radium paint, X-ray machines, nuclear fallout, etc. As another example, consider the wildly varying advice on nutrition that scientists have given in the last 70 years. Reporters who went back to study the original research found out that the accepted advice to avoid cholesterol and fats had more basis in strong personalities than in actual experimental results!

Understand, I am not recommending a return to the Bronze Age, but rather some humility and caution when using a new technology.We have found out over and over again that it is easier to let the genie out of the bottle than to put it back in! It makes sense to move ahead slowly and carefully.

It's a particularly galling/misguided/hypocritical statement on Dr. Tyson's part given he spent an entire episode of his recent Cosmos series exposing and outlining the problem with and controversy surrounding lead paint/gasoline/etc..., the decades it took to discover and determine its toxic effects, and the still more ensuing years with high scientific authority and "consensus" and - even longer - industry denying the fact and trying to keep it on the market as long as possible.

PatSeg

(28,946 posts)Because you come across as pretty close minded with severe tunnel vision. I do believe a lot of caution should be taken with GMO's with lots of testing but I also think a lot of good can be done with them. Evolution can occur in nature and in the lab, who is to say plants sprayed with roundup would not have naturally developed the same resistance as the GMO plants but over a longer period of time? Maybe even having the exact same chemical make up. If the mutation had happened naturally it's okay but when sped up by science it's not? Is that your reasoning? If so it's pretty faulty.
How many of those 1,700 studies have you actually read? You do realize they went through peer review don't you? Science can do good and bad, not just bad and there are a lot of dedicated scientists out there trying to save lives with GMO's who are having a hard time moving there work forward because the anti-GMO lobbying.

(1,648 posts)Is it so they are tastier? NO
Is it so they can make/tolerate high herbicides like RoundUp and 2,4-D? YES But Why? Weeding is expensive and poisons are much cheaper.
How about this 2,000 studies finding GMOs "perfectly safe"? Are they paid for by Monsanto et al? Well, yes.
How about the time the lab rats are re-checked? Oh, the time period is short. Follow ups? NO
You see Cancer and other terrible diseases attack is usually found in longer periods than 30 or 90 days.
So, why would Neil defend GMOs? No comment, but it should be noted that GMOs aren't his field, or even close to SPACE TRAVEL, ETC.
Neil, I'm very disappointed in this...but you can fix it. So, do the right thing and check out the facts, then speak.

1. Science should not be confused with technology. Science is a method of studying the universe, a question is raised, a method of testing that question is developed and then a test is made to determine the answer. If the question can be reduced to one variable, the answer can be found fairly simply. If not, further testing is required. A second step is to repeat the test to ensure that the results are accurate. But - experiments at best only answer the specific question asked.
2.Technology is based on the application of scientific results. Thus, while scientific findings enable us to insert genes into living organisms, they have nothing to say about whether or not that is a good idea.
3. Experience has shown that interfering with the environment often has unintended consequences. For example, after WWII, the use of DDT saved thousands of lives. It was safe to use around humans. However, no one had asked whether DDT would interfere with avian reproduction. If we are failing to ask the right questions about GMOs, we may find out too late that releasing them into the environment was a very, very bad idea.
