The amount of ground planted to transgenic, or genetically modified (GM), crops reached nearly 125 million acres by the end of 2001.

Growth in the use of GM crops increased more than 10% in 2001 compared with that in 2000. And it increased 30-fold since 1996, when the first commercial GM crops were grown.

That's all according to a not-yet-released global survey by Clive James, chairman of the International Service for the Acquisition of Agri-biotech Applications (ISAAA). ISAAA will release the 2001 Global Review of GM Crops later this year. E-mail questions to knowledge.center@isaaa.org.
