Critique of modern agriculture in song

One of our gradudate students sent me a link to this music video performed by a band, Wookiefoot, he recently saw in concert.

If you couldn't follow along, here's a sample of some of the lyrics

Then McDonalds got a farm GM GM GMO
And on that farm he had a chicken and a cow
But they do now you really don’t wanna know
Why must we label it organic
When that’s the way we’ve been growing it for ten thousand years

I don't suppose it would do any good to mention what organic really means or to show what agriculture really looked like 10,000 years ago?
