Rabbi Roodyn

Rav Hirsch explains the final three pesukim of the chapter by saying that contain a central theme that is repeated a number of times in Tanach.

Wherever the pesukim speak of mankind’s eventual deliverance from sin and man’s return to his own morally pure destiny under G-d, we find a mention of a flourishing rejuvenation of nature.

There is a close relationship between the moral conduct of man and the growth or inhibition of the world of nature into which G-d has put man in order to fulfil his task in this world.

Moreover, apart from that, if man fulfils his destiny, the everything that blossoms for man and is used by him for his purposes will also attain its true, higher destiny. But as long as man will take all that serves his life and work and which he subjects to his rule, and uses it solely to serve his sensual desires, then the heavens will mourn when they look down and see what manner of life it is that they awaken with the light of their sun and rear with their drops of rain and dew.
