facetは以前記事中にも表記されておりますので此方も併せてご参照頂ければと思います。(cf.my father's Great Expectations - 田邉祐司ゼミ 常時英心：言葉の森から)文中でのfacetは第二語義の「（（正式））（心・問題・正確などの）面、様相」（『ジーニアス英和辞典 第３版』大修館）となります。念のためOxford Dictionaries Onlineも参照してみますと’a particular aspect or feature of something’ と掲載されていました。(Shou-VR*)
As I See It: Leave choice up to consumers by labeling genetically modified foods
Reporting on genetically modified (GM) crops has led me to conclude that eating such crops renders no problematic health effects, based on various research results. I personally feel that the issue is settled. However, many readers have continued to ask whether such crops are truly safe to eat. There are pluses and minuses to any kind of technology, and I've been struck by the difficulty of getting that message across.
I, too, was previously focused on the negative aspects of GM crops. I once even reported on a paper released overseas that the spread of genetically altered crops could inadvertently increase the use of pesticides.
During a visit in 2002 to Nebraska in a region of the Midwestern United States known as the Corn Belt, I saw firsthand the growing of GM crops. There, I realized that I had been staring at just one facet of the issue.
