Psalms 8:6-9

6 You made him ruler over the creations of your hands; you put everything under his feet: 7 all the sheep and oxen, as well as the animals in the wild, 8 the birds of the sky, and the fish of the sea that pass through the currents of the seas. 9 Yahveh, our Lord, how honorable is your name throughout the land.

The image of God given to our ancestors in Eden primarily has to do with this conferred authority and responsibility to pass on God’s honor by managing his creations. Not only are we our brother’s keepers, we are also keepers of the rest of creation.
