"21So God created the large sea animals and every living thing that moves in the sea. The sea is filled with these living things with each one producing more of its own kind. He also made every bird that flies, and each bird produced more of its own kind. God saw that this was good. 22God blessed them and said, "Have many young ones so that you grow in number. Fill the water of the seas, and let the birds grow in number on the earth." 23Evening passed, and morning came. This was the fifth day."
I love sea animals the best of all animals, I think that they have a grace and beauty which cannot be reproduced by anything which is land based. The birds have a similar sort of beauty. The reason for this, as far as I can tell, is that they have freedom. They can go anywhere, at any time, no fences to stop them or people to control them. They have a freedom which we have taken from or denied to many of the animals who cohabit the dry land with us.
