Only humans consciously experience the world’s complexity and the need to select an environment.

Evidence

A system locates itself in a selectively constituted ‘environment’ and will disintegrate in the case of disjunction between environment and ‘world’. Human beings, however, and they alone in this, are conscious of the world’s complexity and therefore of the possibility of selecting their environment – something which poses fundamental questions of self-preservation. — Niklas Luhmann, Trust and Power, 102
