Average weight of a grain of pollen?

Hi Toby,

I have to disagree with your comment.  Although I do not necessarily
agree with the WWF's position as stated in their web page, refusing
to provide data (merely because I don't particularly support their
policy position) seems 'unscientific'.  If the folks on the list can
assist Mr. Cuddeford in his research, then he is more likely to
produce reliable, unbiased results that can really address the GMO

Although I think, all things considered, that GMO crops do not pose
anything near the risks that have been attributed to them, and that
there are a lot of inflated fears, it is clear that (for whatever
reason) a portion of the public does not agree with this view.
Anything scientists can do to help the public understand our science,
its potential benefits, =and= any reliably documented risks (as well
as any unbiased refutation of risks) seems like effort well worth
