As for the green plant issue I think Corgyps came close to the answer but missed the reality.
Though our Lord, Father/Son/Ghost, may to some seem insensitive because of drowning a whole world of babies and for killing and ordering the massacre of multitudes of babies in various events, he really is quite concerned for our feelings when it comes to the food we eat.
Our Lord, YHWH/Jesus/Spirit, or some combination, made plants reflect green light since if they didn't they would only reflect the black part of the EM spectrum and would look black and aesthetically unappealing. Can you imagine consuming a black cauliflower?
I heard once that our Lord, Yahweh/Esau/Essence, or some combination, made bananas long and round for our consumption convenience (though some may see a sexual overtone to this we have to remember that a famous psychologist, I think Simond Fraud, once said that sometimes a cigar is just a cigar cept this one is yellow and has peels. I didn't even know you could peel a cigar).
By having plants green we are more apt to consume them and keep healthy. Our Lord, Jehovah/Lamb/Apparition, knows what would happen if our tomato sauce and orange juice were black. Yuck. Just ask the Irish about black potatoes. And since cows eat plants they would have black meat! You put it on the grill and would not be able to tell when it was done. That is not healthy.
So along with rainbows, salvation and creation, green plants are a gift from our Lord, Elohim/Hazoos/Casper, or some combination.
