Interesting and funny repartee to the GM corn article...
The story appeared in an online magazine and I was quite distressed by the implications. But there was a very interesting dialogue that happened between an aware & informed reader Mr. Proloy C Pramanik and the author of the article, which I am re-producing here.
I am re-producing the interaction since initially I was stupid enough to post the story verbatim, I feel it my responsibility towards the readers of this blog that I must also provide the following interaction which is both interesting as well as informative and follows a logical inquiry on the same topic.
I confess that I am not qualified enough to understand and appreciate the nuances of such matters, but I hope this conversation below will be of MUCH better use. Read it, towards the end, the conversation becomes both funny as well as literally dripping with satire.
So here it is..
In reply to the article, a reader responds:
And was any ill-effect observed on the pigeons who did eat the GM corn? Did the pigeons die off...? Or are we suggesting that whether GM crops are good or not be decided based on the relative brain sizes of pigeons and crows? Whatever the crows do agree to eat, could that be considered safe for human consumption too?

| Author: Dear Proloy Coomar Pramanik, thank you for writing in, and grateful. I have simply placed my observations, surveyed various competing hypotheses, and then applied what is called Occam's Razor (lex parsimonae), which is a valid as well as time-tested and scientific option that has survived the ages available to all of us. But you have asked a valid question on GM corn vs non-GM corn in Delhi. Please guide me on where I can purchase normal non-GM corn in Delhi's wholesale markets, lately, and oblige. The way I see it, this is our shared courtyard, and we are all eligible to draw any conclusions basis skill-sets and parameters drawn. Ergo, QED, and good luck - and once again, thank you for writing in. Regards/VM | |

| Proloy Coomar Pramanik: If this version of Occam's Razor
were to be considered "scientific", then a falling feather would
certainly be experiencing a smaller gravitational acceleration due to
the earth than a falling stone. Because, it's quite evident to everyone,
be they of whatever persuasions, that a feather does indeed reach the
ground much later than a stone. This razor is outstandingly parsimonious
with respect to truth and a spirit of scientific inquiry. This is without prejudice to the merits of your reported observations. I welcome them. But, conclusions drawn without cross-examination or objective scrutiny lie in the domain of impulsive oversimplification, not simplicity. Unfortunately, I live in Hyderabad, not Delhi. So my knowledge of the Delhi wholesale markets is not something I can be called proud of. But, if indeed the population of Delhi is only getting to eat GM corn now (which even crows refuse to eat), and if I could assume that this has been the case for some length of time, then I'd actually feel a degree of confidence that GM may not be all that bad. I know you've already provided links that suggest that the harm from GM may be long-term (like, say, slow arsenic poisoning). But there is something called as Mean Time Between Failure (MTBF). When hard-disks are said to have an MTBF of 50000 hrs of operation, it's not that any such hard disk has actually been operated for 50000 hrs and seen to survive. What's done is to spin about 500 disks continuously for 100+ hrs each, all together, and finding that not a single disk failed within 100 hrs (and proportionately further). While this approach may not look absolutely convincing, it's surprisingly significant statistically, especially after applying some coefficients, and matches closely with the manufacturers' warranty replacement experience over the actual lifetime of the disks in operation. Therefore, if say 10000 Delhi-ites have been consuming consuming GM corn for one year, and say, 250 of them developed some weirdo symptoms lately, then the MTBF because of GM corn could be roughly considered to be 40 years (assuming that nothing other than GM corn was instrumental in the appearance of the symptoms). We are all free to hold our own opinions and preferences. I respect that. But it isn't the same as freedom to draw any conclusion as one pleases. Conclusions, in so far as they are meant to represent an assertion of a fact (if not irrefutable, at least a strongly evidenced one), have to be based on common agreement. However, to fully respect people's right to exercise choice, I strongly advocate very explicit marking of such products as GM ones. This should be statutory. Those who wish to take the risks (for reasons best understood by them) can buy and consume, those who don't wish, can refrain. (The pigeons and crows, unfortunately, were denied that right to informed choice -- but looks like they figured that out regardless. ;-) ). ------------------------------------------------------------------ |
| Author: Dear Proloy ji, 1) A feather that has been tightly compressed will fall at the same speed as a stone, so that takes care of that - and a stone that is thrown in the water may well not fall as it skips a few times over the surface while the feather floats on. Occam's Razor is capable of responding to all these aspects . . . 2) Scientific enquiry has for decades been trying to prove that smoking is not the cause for an assortment of ailments. Let us take it with a pinch of Sodium Chloride. 3) The crows are not eating corn on the pavements of Delhi anymore. The crows are not attacking corn fields anymore. The crows are probably the smartest of all birds and in terms of survival skills match the cockroach. 4) My form of scientific inquisitiveness teaches me to look beyond the lab and numbers. It is like being on a ship at sea or an airplane in the air, and I qualified for both in my days - we have the best of equipment, but still, nothing beats looking out of the window, cockpit, bridge wings, smell the air, check the sea-state and traffic around, see what the clouds are up to, gaze at the horizon and state of the world, to get a wider more holistic understanding of what is really happening out there. +++ Having said that, I truly appreciate your writing in, and hope you shall carry out your own enquiries too and let me know more observations from your end? thank you!! Best/VM |

| Proloy Coomar Pramanik: Dear VM, Thank you for your responses. I do appreciate your writing this article in public interest, and trying to make people aware of the dangers of genetically modified corn (and, I'd assume, by extension other GM food). It's indeed a matter of serious concern if crows have started a wholesale boycott of GM corn, have refused to eat GM corn spread on the streets, and have also stopped attacking GM corn fields (though I'm not quite sure why one should be inclined to invite such an attack). That the crows have done this, but not the pigeons, is indeed testimony to the superior intellectual capacity of the crows (inferred either by applying Occam's Razor, or by looking out of the window, or by a combination of both). I'm not too sure how the crows actually got to know that it was genetically modified, given that even humans cannot distinguish without being told. (I'm getting to develop an inferiority complex as regards the crows now...) Since the color and texture seem to be no different, for the crows to be able to detect it from a distance, and boycott it, it must be an olfactory signature that's characteristic of the GM corn. I'll have to do some research on whether crows do have noses. Anyway, admire your scientific inquisitiveness, across land, water and sea. It's good to apply Occam's Razor principles through open windows, and also through television screens, movie theatres, coffee-table magazines and placards. One needs to keep one's scientific eyes open to all of these. There is just a minor point of detail regarding your article. The Monsanto DEKALB corn variety that you've mentioned is NOT genetically modified. The GM varieties usually go by the name BT. This variety is biotechnologically modified to contain a gene from soil bacteria called Bacillus Thuringiensis, which produces a toxic protein that kills plant pathogens. As far as I know, the only permitted GM crop in India is Bt-Cotton, which now has extensive adoption, and has revolutionized production. The first food crop that was proposed was Bt-Brinjal, but that was shelved after the huge brouhaha over it last year. The government has not yet permitted Bt-Corn production in India (or any other food crop), though Monsanto does sell it legally in several other countries including the US and China. So, if you believe the Delhi supermarkets are flooded with GM corn (which even crows are refusing to eat), it deserves a representation to the government, if not a PIL, because such GM corn has to be completely contraband, in view of such production being yet to be permitted in India. As per the Monsanto India website, the DEKALB corn varieties (17 of them sold in India) are regular hybridized corn. Which means they have been produced by selective crossing of natural corn varieties themselves. They do not contain foreign genes (like the Bt gene) implanted from foreign organisms. So, calling them GM corn is completely misleading. Of course, all hybridization is a genetic procedure, but then so is all sexual reproduction! http://www.monsantoindia.com/MIL-product... Hybridization is a hundreds of years old procedure that hasn't exactly been a Monsanto invention. It has been practised in India too since ages, including in gaon-dehaat, and is the bread-and-butter stuff of most agricultural universities and institutes today, whose day-to-day research consists in evolving newer, higher-yielding, disease-resistant hybrid varieties. I'd be interested in knowing whether the crows only have objection to Monsanto DEKALB hybrids, or whether they have equal dislike for homebred, say, PUSA or SONARA corn too. If just DEKALB, I'd be quite inspired by the crows' patriotism! The DEKALB hybrids too have been in existence since the 1910s, which is when the eponymous company started (which was taken over by Monsanto in the late 1990s). The biotech procedures of gene-injection are only a few years' old invention. Monsanto has plans of introducing Bt-Corn in India in 2012-13 (of course, subject to governmental approval) as per the following article: http://www.business-standard.com/india/n... Unfortunately, I've not had any first-hand experience in scientifically investigating the effect of GM foods -- it's not my domain of expertise. When I do manage to get my hands on some Bt-Brinjal or such, I'll try to leave them on the pavement, and report back looking over my window on whether rats are showing inclination to eat it or are giving it a thumbs down. Till then, perhaps the following paper on the effects of GM crops on mammalian health may be of use, for those interested: http://www.biolsci.org/v05p0706.htm Here is another survey on the issue: http://www.csa.com/discoveryguides/gmfoo... Regarding whether or not feathers need to be 'tightly compressed' to experience the same gravitational acceleration as a stone, is elementary high-school physics. But that is beside the point since you're not making any claims that basic physics is needed to be known for scientific inquiries. In the meantime, let's raise a toast to the crows, who have stopped eating GM corn even before it has been introduced in India. Such proactive boycotts and protestations will go a long way in furthering the public cause in India. Btw, did you verify that the "more expensive" jowar and bajra that the crows now seem to have upgraded their diet to, aren't themselves Monsanto crops too? Last heard, Monsanto does sell high-yield hybrid varieties of those seeds too in India. It just piques me a little bit that nowadays scientific articles seem to get published more in politico-economic journals, and sometimes Cineblitz, Gladrags, and Paanchjanya, than in actual science journals. Modern democracy at work! Certain M.S. Swaminathans and Norman Borlaugs have spoken in favour of GM food crops, but then in what way can they be a match for the intelligence of crows? After all, what they write are not scarecrow articles. http://www.fnbnews.com/article/detnews.a... http://www.agbioworld.org/biotech-info/t...
