Mendel would be so proud! Seriously though, legitimate question here: if I buy seeds at the store and plant them to grow fruits and vegetables, are those genetically altered? I'm not trying to suggest i'll start a 40 day fast if all the foods I know and love are modified. I'm really just curious.
Yes. And guess what: so are you. You've maybe heard about this thing called evolution? Works by modifying genes :-)
That's not to say that I really approve of a lot of the particular modifications that are made, just as I don't approve of "organic" super-sweet corn, or apples that taste like balsa wood soaked in apple juice...
That's not how roundup works. Your understanding of organic food is based on a critical factual inaccuracy.
Good point! Strictly speaking, Roundup (tm) or glyphosate is a herbicide, not a pesticide. That is, it kills plants, not insects, and is typically used to control weeds. 'Roundup Ready' (tm) plants have a gene that confers resistance to glyphosate. That gene is purely natural, though, and some weeds are already evolving their own resistance to glyphosate, just as bacteria have evolved resistance to antibiotics.
The argument's not really new. For instance
Say there be;
Yet nature is made better by no mean
But nature makes that mean: so, over that art
Which you say adds to nature, is an art
That nature makes. You see, sweet maid, we marry
A gentler scion to the wildest stock,
And make conceive a bark of baser kind
By bud of nobler race: this is an art
Which does mend nature, change it rather, but
The art itself is nature.
Shakespeare, 'The Winter's Tale', Act 4, scene 4.
