There's definitely a few legitimate concerns about genetically engineered crops, but they're mostly based on the new genes "escaping" rather than any directly adverse effects on humans (so the people who don't want to eat stuff because it's genetically modified are silly).
And how in a world would a gene escape to anywhere? I am baffled.
Anyway, here are some snazzy online resources which might be helpful, if not for this subject, then at least for others.
Personally, I'd love to see a "book club"-styled thingy, where people choose an online course to follow, and then discuss, review and generally talk about the subject in question. Just thinking aloud(?).
http://academicearth.org/ - a repository of online courses from universities like MIT, Harvard and whatnot. The biology section doesn't contain any strictly "genetic engineering" related courses, but I suppose there are at least a few lectures within, which relate to the current subject.
http://thesciencenetwork.org/ - these are more of a collection of panels and individual lectures, rather than academic courses. Good for keeping track of current developments in a given field, and simply fun to watch, as inteligent people talk about their passions(like, their scientific focus, not their sexual adventures).
http://richarddawkins.net/ - Richard Dawkins' own website. The man is a great popularizer of scientific thought in general, biology in particular. Don't go there if you want to mix science with religion - Dawkins will eat your head.
http://lesswrong.com/ - great site if you want to get an intuitive, yet in-depth explanation of scientific thoughts too heavy on technical jargon to approach. Somewhat hard to navigate, and more focused on philosophy of science rather than any particular subject, but if you'll ever want to get a hang of e.g.quantum physics(in a qualitative way), this is the place to go to.
