"Sugar, you might think, is just sugar, no matter where it comes from. But not anymore.

About half of all sugar in the U.S. comes from sugar beets, and the other half comes from sugar cane. Now, for the first time, sugar traders are treating these as two different commodities, with two different prices.

It's all because about eight years ago, nearly all the farmers who grow sugar beets in the United States decided to start growing genetically modified versions of their crop. The GMO beets, which can tolerate the weedkiller glyphosate, otherwise known as Roundup, made it easier for them to get rid of weeds."
