A massive, "unprecedented escape" of genetically-modified crops into
the wild
A massive, "unprecedented escape" of genetically-modified crops into
the wild Genetically-modified canola has been breeding undetected in
the American wilds for at least "several generations," say scientists.
The escaped GM canola has already mutated into a never-before-seen
strain, and now it may be modifying other plants too.
Canola is a yellow flowering plant that is used to make oil.
Researchers working in North Dakota, found strains of transgenic canola
growing wild on roadsides far from local farms - meaning the GM plants
had spread quite far. They found two strains of transgenic canola.
According to Nature:
"The extent of the escape is unprecedented," says Cynthia Sagers,
an ecologist at the University of Arkansas in Fayetteville, who led the
research team that found the canola (Brassica napus, also known as
rapeseed).
Sagers and her team found two varieties of transgenic canola in the
wild - one modified to be resistant to Monsanto's Roundup herbicide
(glyphosate), and one resistant to Bayer Crop Science's Liberty
herbicide (gluphosinate). They also found some plants that were
resistant to both herbicides, showing that the different GM plants had
bred to produce a plant with a new trait that did not exist anywhere
else.
Sagers says the previous discoveries in other countries of
transgenic canola populations growing outside of cultivation were often
in or near fields used for commercial transgenic canola production. By
contrast, her research team found feral populations of
herbicide-resistant canola growing along roads, near petrol stations
and grocery stores, often at large distances from areas of agricultural
production.
So why does this matter? Because if the transgenic canola starts
swapping genetic material with weed populations - something that is not
unlikely - it could spread herbicide resistance to weeds. And that
would leave farmers with no way to fight plant pests - and potentially
massive crop failures as a result.
