Blundell & Blundell Concepts in Thermal Physics tells us that in a thermally isolated system such that $\mathrm{d}Q = 0$, the inequality $\mathrm{d}S \geq 0$ always holds true. Thus, "it shows that any change for this thermally isolated system always results in the entropy either staying the same (for a reversible change) or increasing (for an irreversible change)."
From what I'm reading, if we take the universe to be a thermally isolated system, the first of the two laws of thermodynamics become:
- $U_{\text{universe}} = \text{constant}$.
- $S_{\text{universe}}$ can only increase.
Hence, any attempt of human organization can only increase the entropy of the universe, and at most give zero change (if we clean up, that can be considered as a reversible process). So by this perspective, are we only increasing the disorder of the world?
