[This Jewish poem, and the Jews that used it in worship,] embraces things that are no use to man. In the great Psalm especially devoted to Nature, from which I have just quoted . . . we have not only the useful cattle, the cheering vine, and the nourishing corn. We have springs where the wild asses quench their thirst (11), fir trees for the storks (17), hill country for the wild goats and “conies” (perhaps marmots, 18), finally even the lions (21); and even with a glance far out to sea, where no Jew willingly went, the great whales playing, enjoying themselves (26). (The parentheses are references to the verses in Psalm 104.)

Lewis said it well. Psalm 104 describes not only living things that were of great importance to the ancient Jews, but it also praises the diversity of God's creation, specifically mentioning aspects of that creation that advanced the interests of non-human animals, including some that the Jews would rarely or never be associated with.
Lewis didn't refer to it, but I'll quote part of that Psalm:
Lewis, nor the Psalmist, knew about some of the remarkable discoveries in astronomy, over the last couple of decades. Surely galaxies, stars, and planets that humans have yet to discover, even from long range, also show forth the goodness and glory of God's creation! But they aren't useful to us now, and won't be for the forseeable future. Did Eris, a dwarf planet in our own solar system, which was not even discovered until 2005, ever do anything good for you? How about the Horologium Supercluster, which is about 700 million light years away? But they, too, are part of the good creation that God brought into being.
Thanks for reading!
