Fundamentally the human body is the universe, the infinite complexities of all chemistry can be and is discovered from within. Despite its personal chaos, it is also capable of restraint and this capability is practiced no where else in the universe. So while the body is the universe, its capability for restraint appears to be separate.
There is an ongoing war between our bodies (chaos) and ourselves (restraint). Put another way there is an ongoing war between our bodies (chaos/evil) and ourselves (restraint/order/good). When both exist simultaneously, there is conflict. The conflict is neither good or evil but instead exists to achieve resolution.
When resolution is not discovered, insanity ensues. Insanity being the repetition of non progressive actions or events. In this situation there must be an outside intercession. For example, the dinosaurs being killed ended insanity and allowed for new evolution.
In this scenario a “harmonious” ecosystem is insane, since there is neither forward or backwards progression.
