The risk isn't derived from the technology but how it is used. The proprietary technology is used to prevent farmers from creating their own seed (including using copy right laws) while increasing their dependency on matching pesticides. Industrial agriculture is not sustainable - insect populations are dwindling because every square foot of landscape is sprayed with poison. GMO is used to further industrialize agriculture, e.g. by making crops resistant to poison, which in turn can (and will) be used more liberally.
