And the GMO corn did have something to do with round-up . . . it was "round-up ready" corn, IIRC, which is to say that it's modified so that round-up doesn't kill it. I also wouldn't worry about the round-up use across the street, unless it was a very windy day and the wind was blowing towards your garden. But I also was desperate enough to actually use round-up in my food garden, so take my opinion for what it's worth on this matter.
And I just can't help but voice my agreement about the disgustingness that is Monsanto. I love that they genetically engineered a crop to increase use of their patented pesticide, then proceeded to sue people when it cross-pollinated with their crops . . . and it's not like the corn asked for their consent, it's wind-pollinated for pity's sake. ARGH! Anyway, to prevent ranting I must stop now . . .
Well, except for one thing. Did you know that Monsanto also produces a whole lot of the plastics that make up carpets? I think my dad told me that Dupont was owned by them, but I don't think that's right. However, I did once, while learning to knit, buy an acrylic ball of yarn. I was surprised and displeased when I got it home to discover that it was made by Monsanto. ARGH!
