Most cornfields are doused in Round-up weed killer.

I prefer that my corn is not.

Is this an unscientific concern?

If you haven’t tested the hypothesis, or at least studied tests by others, then by definition, yes. Doesn’t by itself make it unreasonable, but it is unscientific.

No, but that's a function of the use of Round-up. Don't think the author is saying the term organic should be banned. You have that choice. As to organic being more nutritious or tastes better there's not much to back that up.

Yes it is. Unless you are a plant or have plant genes and have received a dose within the past week. In that case, your roots will begin to die, and your body will wither away.

But not to worry, your seeds will sprout because the glyphosate has dissipated and is breaking down into simple compounds.

If, I say if, you are human your biggest risk would be drinking the commercial 46% concentrate (not the 3-4% in stores). That would be guaranteed to give you a very bad stomach ache, and in the only known instance of drinking that concentrate, kill you.
