Man is meant to fill up the world. The world exists for him.
And by that I mean the actual story of Noah, not the bad movie currently playing in theaters.
Noah reflects the same message as that of Creation itself. It places man first in the universe. Creation culminated with man. The undoing of man, undoes Creation.
Hollywood liberals have launched two big budget "Noah" movies recently (Evan Almighty with Steve Carrell and Noah with Russell Crowe) and attempted to market them to religious audiences. The former bombed and the latter is getting ready to bomb. Both movies were an environmentalist misreading of the place of ecology relative to man.
Man does not exist for the sake of the world. The world exists for the sake of man.
In the Biblical worldview, man is the purpose of Creation because the knowledge of G-d is the purpose of all life. And so G-d sweeps away all life on the surface because of human corruption.
Noah's ark repopulates the world, but it does not do so for the sake of the world, but for the sake of man. The first thing that Noah does on leaving the ark is bring sacrifices from the animals he just saved to G-d.
G-d's command to Noah is a collection of anti-environmentalist messages. (Genesis 9:1-7)
And God blessed Noah and his sons, and said unto them: 'Be fruitful and multiply, and replenish the earth.'
And the fear of you and the dread of you shall be upon every beast of the earth, and upon every fowl of the air, and upon all wherewith the ground teemeth, and upon all the fishes of the sea: into your hand are they delivered.
Every moving thing that liveth shall be for food for you; as the green herb have I given you all.
Only flesh with the life thereof, which is the blood thereof, shall ye not eat.
And surely your blood of your lives will I require; at the hand of every beast will I require it; and at the hand of man, even at the hand of every man's brother, will I require the life of man.
Whoso sheddeth man's blood, by man shall his blood be shed; for in the image of God made He man.
And you, be ye fruitful, and multiply; swarm in the earth, and multiply therein.'
It's a succinct refutation of the entire moral viewpoint of the current Noah movie. The world exists for man. Animals exist for the purpose of man. Man is meant to fill up the world. The world exists for him.
Noah's message is not about the environment. It's about the guardianship of the earth through character. It's not the physical environment that the Bible is concerned with, but the moral environment of the mind, heart and soul of man.
