I found it interesting, but don't know if it is significant, that God specified the seed-bearing aspect of the plants and fruit which were to be food for humans. In contrast, the beasts, birds and creatures which move on the ground seemed to have been given every green plant for food, with no mention of whether these had seeds or not.
[After all the effort to grow seedless watermelons and other fruit, wouldn't it be ironic if there was something in the seeds which was actually especially good for us?!]
Several times during the discussion of God's work of creation on specific days, God declares His work "good". (Genesis 1:10; 1:12; 1:18; 1:21; 1:25) At the end of this passage, though, "...God saw all that he had made, and it was very good." Just sayin'. [This is probably partly why I get a little testy when people say that men and women are just another form of animal, instead of acknowledging that humans are made in God's image.]
