Organic food is great but comes at a price. Land is scarce, we are expanding, we need cheap food.

Speaking from a purely scientific background, unless the genetic modifications make the plant over-produce some natural carcinogen (none that I can think of right now) or toxin, all that's really happening is overproduction of the reproductive organs/fruiting bodies -- don't see a problem with that.

I'm curious, is there any argument against GMO aside from the supposed negative effects on humans (i.e. wiping out native plant species by successfully competing for resources)?

If I give someone a genetically modified tomato and an organic tomato, the body's processes to break it down will be the same -- the only difference being one will simply have more plant mass. As a consumer I'd be more worried about the soil conditions and fertilizers used to grow a plant than its genetic make-up. Plant DNA/cellular material is all going to be destroyed/broken down by the time it reaches the stomach anyways.
