Yes, the "feeding of hell" is what maintains the planet in its current state and point of evolution, so from that point of view nature needs it to be that way. However, the planet is also evolving and developing, and for it to reach a new level of being, everything within it must change; it too must be cleansed of impure elements. "As above so below." That is why there will be periodic cleansings, as the planet attempts to evolve. Eventually, a planet can become clean of impurities, such as the sun. In such as case, the overstuffed mineral kingdom (abyss) is not needed, since the planet has evolved beyond that stage.
The golden age is a period of time when those who are incarnated in human bodies are awakened; the other levels and kingdoms of the planet still have essences undergoing their respective processes.
