Risk analysis of genetically altered foods.



Hi Patricia,
    I think that your analogy with Chernobyl
and Bhopal was very apt, perhaps especially
with respect to the use of nuclear energy.
Like nuclear energy, the technology has the 
"potential" for some very great benefits that 
some of us wouldn't want to do without(I'm thinking
X-rays and radiation therapy).  But 
it's *all* very risky, and *some* of it has the 
potential to be exceedingly dangerous, even 
threatening our lives and civilisation.  
    I agree with you completely that these
technologies should have been evaluated *a great deal*
more before they are released, or even developed. 
     That's why I'm wondering if there has
been an attempt to classify the type and degree
of risk of various genetic alterations.  I believe
that the pressure to create and introduce these
technologies is so great that it won't be stopped 
unless there is a wreck. New alterations are 
being released regularly, everywhere. The "cat"
is out of the bag, and it isn't likely to go 
back in. I think we'll have to deal with it
as a reality and not pretend we can make it go
away. So I would like to have a way to systematically 
understand and evaluate the risks of the various 
gene manipulations that affect food and crops. 
    For example, from my uninformed point of 
view, making a vegetable that kills insects
seems to rate highly in the risk category.  Making
a crop that tolerates herbicide might be moderate.
Making a crop with a thicker root covering that
resists root maggots might be a lesser risk.
Of course, there are a host of unknown things
happening in the background that we don't know
about that may make a relatively benign alteration
dangerous.  (In the same way that one of the
big risks of irradiated food is not the irradiated
food itself but the proliferation of nuclear
mines, processing plants, waste facilities, etc.
required to support it). 

   As far as how roundup tolerant genes rank
against Mother Theresa, that likely has as much
to do with one's opinion of Mother Theresa
as one's opinion of Roundup. ;-)
