PLANT SCIENCE:
Communal Benefits of Transgenic Corn

Genetically engineered crops represent one of the most controversial and rapidly adopted technologies in the history of agriculture. First grown commercially in 1996, transgenic crops covered 135 million hectares (ha) in 25 countries during 2009 (1). To reduce reliance on insecticide sprays, corn and cotton have been genetically engineered to make insecticidal proteins derived from the common bacterium Bacillus thuringiensis (Bt). These Bt toxins kill some devastating insect pests, but unlike broad-spectrum insecticides, they do little or no harm to most other organisms, including people (2). Many pests have rapidly evolved resistance to insecticides, however, spurring concerns that adaptation by pests could quickly reduce the efficacy of Bt crops and the associated environmental, health, and economic benefits (3–7). On page 222 of this issue, Hutchison et al. (8) rein in some of those concerns, documenting a landmark case in which Bt corn has remained effective against a major pest for more than a decade, yielding billions of dollars of estimated benefits to farmers in the midwestern United States.

我這裡只張貼了第一段，很清楚地表明作者態度就好了，願意看更多細節論述和所介紹的Hutchison et al 研究報告的，可以自己去閱讀。有不同意見並極力反對轉基因的，請按照上面提供的作者email去信討論和/或猛批。

俺說過，「整人」的事兒俺不懂，挨了整也不知道是誰整的。俺代表越來越多的過敏受害者，給你們這些靠整人吃飯的提出一個科研提案，能不能研究一下轉基因食品和過敏體質有沒有correlation呢？

應該早就有過研究了。basically，如果轉進來的基因會生產讓你過敏的蛋白，你就會對這種作物過敏，反之，就不會過敏。所以你對哪種作物過敏與否，和這種作物是否是轉基因的，沒有直接聯繫。

除了已知的過敏蛋白可以直接導致過敏癥狀，是否還有其它未知過敏源也能導致過敏呢？特別是，轉基因食品可能不是直接的過敏源，但是否會在長期食用后，產生某種短期內無法測定的積累效應而導致免疫系統不斷進行「微進化」，在人體上出現類似基因漂移的現象，逐漸形成過敏體質呢？

多謝分享

任何作物都會如此，和是不是用基因工程來轉基因無關，傳統育種同樣轉基因。

Thanks for sharing this article :handshake

The economic impacts of transgenic corns to US farmers were highlighted in this article. Nevertheless, it hasn't been, neither was its secondary emphasis, touching the ecological or health/safety impacts of this sort of crops standing from the regional/international scope. Since the transgenic crops were just being introduced commercially in 1996 - I assume this means its use becomes more widespread in the developed world after 1996, the definitive ecological and longterm toxicological effects of its use on humans and environment may not be available to scientists, because these effects may take decades to surface.  We should recognize that there is yet some underlying risk that has yet to be resolved here. If you really study the launching and legalization of transgenic crops in the US, it was more of an economic concern driven by some quarters of political force, that make them into highways. The longterm health effects of such crops and their potential negative ecological repercussions were insufficiently addressed, although US FDA/USDA had made sure some preliminary data from animal studies to support their longterm use did not harm the test animals on several discrete toxicological measures/indices.

我建議過的，你這一段可以發給那個作者。

如果你對轉基因作物和過敏的問題要嚴肅認真地去了解並準備好研讀N頁嚴肅科學論文的話，我可以給你貼整篇的綜述，發表在Nature Biotech2008年上的。何如？

你知道俺是會從teleogical的角度多看一眼「自然」作物和「人造」作物的區別的， 有時候有創意的火花就是從多看一眼嘣出來的:P 。

俺沒戲了，看不懂，也學不會了，看俺家丫頭有沒有這方面的天賦吧。

管它是不是轉基因，居然有那麼多好處就不怕名帖了。將轉基因的東西貼上標籤賣，讓人選擇就好了。（下年開始銷售不標籤的轉基因三文魚:P）

There is uncertainty that surrounds the long-term effects of transgenic crops on population health, ecology and environment. We are playing the odds that we believe we will be ok to allow extensive use and growth of transgenic crops based on limited research that has yet to guarantee we will not lose in this game.

not really a belief. basic scientific understanding provides reasonable speculation, not some belief without any ground truth

without any ground truth在美一方 發表於 2010-10-21 23:13

the word "truth" sounds a little too strong, better to use "observed facts" or "propositional theory". just a little bone from egg.
