haven't seen it but I hope I can ask you to read this :
When buying organic pays
: this one talks about which foods are worth buying organic and which ones aren't.
The other thing to keep in mind, and you probably are already doing this if you have thought about buying organic, is that sometimes it takes significantly more energy and resources for an organic product than for a non-organic product, even with the use of pesticides. I try to eat and buy organic as well, so I'm with you. just adding my $0.02. :)
