America is just beginning out to find out the hard way that
growing GM crops with no wild relatives to share their genes with doesn't
actually mean they'll stay in the field and under control. Even after very few years' cultivation, GM
alfalfa is now flourishing on US road verges and spreading its genes far and
wide [1].
Europe has an interestingly different version of the same
problem.
Maize, MON 810, is the only GM crop grown in Europe, where
it has no wild relatives and doesn't grow easily outside of cultivation. However, no one expected wild weedy relatives
of maize to make their way from Mexico and Central America all the way to Europe.
'Teosinte' species were first noticed growing in Spain in
2009 and have now reached such densities that local governments have prohibited
maize cultivation in a bid to stop the spread.
The concern is that teosinte can cross-pollinate with
maize. It's already an invasive species,
and breeding with MON 810 could make it worse.
MON 810 contains a 'Bt' gene which generates an insecticidal
protein to keep pests from harming
the crop. Unfortunately, inside teosinte, Bt may well
diminish natural environmental control from plant-eating insects.
All the signs are that Monsanto hasn't fulfilled its
obligation to monitor the potential environmental hazards arising from its GM
maize, and that the European Commission is oblivious to the problem.
As Testbiotech has pointed out:
"If there is now a wild relative of maize in Europe, it is obvious that the risk assessment of MON 810 is no longer valid and that its authorisation for cultivation should be withdrawn immediately by the European Commission."
OUR COMMENT
Tell the UK and EU governments to face facts: artificial
genes are uncontrollable.
