Something that lacks any good cannot have an enduring existence. This is because the good contained in every creation was a fundamental element in its creation process, and without this essence it has no enduring existence, doomed to extinction. Individual creatures may not fulfill their potential and as individuals may be deficient and lack endurance. G-d created and sustains every element of the world in order for it to fulfill its purpose. And that purpose is built on providing an environment for MAN to fulfill his purpose.
Every creation is dependent on man, in whose service it was created.
If man doesn't function as intended, the entire creation loses its purpose and becomes nullified. This question is answered in the Midrash which illustrates the destruction of the animals due to man's failure. A king prepared a lavish wedding and fancy house for his son, only to have the son rebel against his father. Similarly, because of man's failure, G-d destroyed everything that had been created for him. Only when man is good, fulfilling his purpose, does he have endurance, which then gives endurance to the entire world that was created solely for man and depends upon him.
