Is there an _ethical_ problem here?  I guess I can parse this as
meaning, "if we failed to be concerned about this possibility and
released the engineered corn without satisfying ourselves that it
won't happen, we would be behaving unethically".  Certainly I agree.

Since comparable transfers of desired traits have been performed by
selective breeding since the Neolithic (not to mention that horizontal
gene transfers occur all the time in nature), I still don't see the
_qualitatively_ new ethical considerations that you seem to think
exist here.  (Introducing rabbits into Australia is a good
pre-biotechnology example of failing to anticipate massive undesired
consequences of an environmental manipulation.) Don't get me wrong- we
clearly need to start thinking a lot more seriously about the
potential undesired impacts of _all_ new technologies.  I just think
that to single out biotechnology as some kind of special case borders
on superstition.
