Really, the term Genetically Modified Food or Organism is a bit of a misnomer. Ever since the dawn of agriculture (even as hunter-gathers, unconsciously) we've been artificially selecting for traits that we found desirable in our food. Since the 1920s, we've taken control even further, "engineering" particular desirable traits. The term would be more scientifically accurate as "Genetically Engineered Organism". I've found that, usually, the most fervent anti-GE believers are usually the ones that don't understand the underlying science around the issue.
I usually upload the audio from videos I post—for those hungry iPods—but I feel like this one should be watched for full effect, so have at it and share with your friends.
