Perhaps the entire biosphere is a symphony that we must not silence?
Does this symphony need an external conductor? Or is it more like a jam session, beginning with a chaotic mix, which unfolds and evolves into a beautiful piece of music? Consider the following definition of Chaos Theory: https://en.wikipedia.org/wiki/Butterfly_effect
Chaos theory is the field of study in mathematics that studies the behavior of dynamical systems that are highly sensitive to initial conditions--a response popularly referred to as the butterfly effect. Small differences in initial conditions (such as those due to rounding errors in numerical computation) yield widely diverging outcomes for such dynamical systems, rendering long-term prediction impossible in general.
