4、nt Pioneer, Dow Agrosciences and SyngentA.The preliminary decisions are circulating within the European Commission, which has the final say. Some officials there are skeptical of a ban that would upset the powerful biotechnology industry and could exacerbate tensions with important trading partners
5、like the United States. The seeds are not available on the European market for cultivation.In the decisions, the environment commissioner, Stavros Dimas, contends that the genetically modified com, or maize could affect certain butterfly species, specifically the monarch, and other beneficial insect

Europabio says that the crops grown using the genetically modified com are already
14、imported into several European countries, including France and Germany, where they are used to feed animals like cows and chickens.Rob Gianfranceschi, spokesman at the United States mission to the European Union in Brussels, said it was too early to comment on a decision that had not yet been formal
