GMO's

Genetically Modified Organisms.  Typically this discussion is debated in relation to foodstuffs.  I personally have no objection to GMO foods in general.  I have a hard time imagining how humanity is going to feed the growing population of humans on earth without GMO foods.  If studies have shown a food to be safe, then I do not oppose eating it.

But there is a lot of concern on this topic.  People are very scared of genetic modifications.  For myself, even as a child I loved the idea of genetics and genetic manipulation.  I fell in love with Punnett Squares when I was 12.  The science of genetic selection is fun and exciting to me.  I tend to assume that opposition to GMO foods just boils down to fear of science.

But I know a lot of intelligent people who are very concerned about GMO foods.  I would like people who are against GMO foods to comment here and tell me why.  If you can provide data against GMO's I would appreciate it.

I am biased to support GMO's until proven otherwise.  I think there should be discussion of them.  We need to make sure that GMO's are not doing things like killing bees.  We need to protect against genetic patents penalizing inadvertent cross pollination.  In fact I think there needs to be a serious discussion about the wisdom of allowing genetic patents.

I don't want to go on too long.  I want a discussion here, because I would like your help in forming a better more informed opinion.  What's your take?
