Psalm 104:30 (NIV) When you send your Spirit, they are created, and you renew the face of the earth.
An inescapable fact of God's economy is that death strikes down one generation, and a new one is raised up to take its place. When animals die, either by violence or through age, it is as if God were hiding His face. But at the same time that these fall and return to... dust, God sends forth His Spirit and repopulates the earth with what seems like a fresh creation. On the one hand there is a constant wasting away, on the other hand a continual renewal of the face of the earth. -- William MacDonald, Believer's Bible Commentary
