The thing about not eating meat is pretty important.  Until Adam and Eve sinned, nothing had to die.   But when they did sin--that sin being disobedience--God required a live animal for a  sacrifice, a covering for sin. ( Genesis 3:21)  He made them coats of skins to cover their naked bodies.  He sacrificed an animal to cover their sin.  Then God casts them out of the garden lest they should eat of the Tree of Life and live forever.  The prototype for a sacrifice has just been set by God.  

Genesis 1:32  "And God saw every thing that He had made, and behold, it was very good."  (Everything that he had done was perfect at this point. ) "And the evening and the morning were the sixth day."

Genesis 2:1  "Thus the heavens and the earth were finished and all the host of them." (Millions and millions of animals.  Millions and millions of stars and galaxies.)

We aren't getting new animals on the earth.  Or anything else.  God was done.  Animals became prey after man sinned.  Animals have been going extinct (they are not evolving into other species) for thousands of years--because we have not done the five things that God asked us to do.  He asked us to care for the fish, birds, cattle (mammals), earth, and creeping things.  That means that we must also care for the water, air, food for animals, soil, and the clean up crew of creeping things.  We are responsible for the habitat of all creatures.  We've pretty much blown that.  Just in the ocean, there are islands of discarded plastics.  And discarded fishing nets.  They trap and kill whales and other large animals every day.  And then there is smog, air pollution.  And chemical waste in the soil.

My brother (doctor, missionary to China) said that they tested all of the children they treated in China including their own children and  hundreds of missionary children, and without exception, every one of them tested well above the acceptable level for lead in their bodies.  China dumps everything in the soil--just as we used to do.   Produce that is coming up out of the ground is not coming up roses.

I am done with explaining the sequence of events after Gen.1:1  The word 'create' is used to describe three events.  1. The heavens and the earth.  2.  New kinds of animals.  3.  Humans in the image of God.   The word 'let'  or 'made' is used for everything else.
