主题：六扇门那些事儿第三部 53 兼职。 -- 史老柒
Sorry can't type Chinese now.
One thing I probably know:
Corn syrup is used in many, many, many processed food products. And that is the major way for Americans to consume GM corns as direct food - if not counting the meat products coming from livestocks feeding on GM corns.
1 bushel of shelled maize (corn) at 15.5% moisture by weight: 56 lb[2] = 25.4012 kg
US exported 20% of the annual product of corn, and consumed the rest 80%.
28.6% of the 80% went to making fuel, and 58.64% of the 80% were feed to livestocks. Then the remaining 12.76% of the 80% (10% of the total 13M bushel) were processed into different forms, and were supplied to the market as direct human food.
Although you may still argue that the 10% used for direct human consumption is less than the 14% of none-GM corn produced, it is a well known and intensively discussed topic that the corn syrups used in food industry are mainly made from GM corns.
You can regard corn syrup as one magic ingredient for the food industry. The other magic ingredient is soybean protein, which, in the US, mainly comes from GM soybeans.
In the US, it is estimated that 75% of processed food (what Americans like most 
) contains transgenic ingredients.
Next time when you buy any processed food, including biscuits, candies, fries, burgers, sausages, hams, drinks... basically anything that's not in the animal or plant's original form, check the ingredients for the two magic bullets.
And the 58.64%x80%=47% of the yearly product of corn that fed to livestocks will still end their journey in human stomachs.
http://en.wikipedia.org/wiki/Genetically_modified_food
In the US, by 2009/2010, 93% of the planted area of soybeans, 93% of cotton, 86% of corn and 95% of the sugar beet were genetically modified varieties.[11][12]. Genetically modified soybeans carried herbicide-tolerant traits only, but maize and cotton carried both herbicide tolerance and insect protection traits (the latter largely the Bacillus thuringiensis Bt insecticidal protein). In the period 2002 to 2006, there were significant increases in the area planted to Bt protected cotton and maize, and herbicide tolerant maize also increased in sown area.[29]
Of course, what Americans do is not always the best. North American food and the way many north Americans eat, are probably the two worst things you can find in the world.
But talking about China, China is a country with barely enough(?) arable land and a growing, huge population. Organic? 40 years ago, everything in China was organic, but they were just not enough.
For this following question, I think you may consult the [Iron Hand]:
