>>10950835The irreversibility of the second law of thermodynamics is a statement of the initial conditions of the Universe. The Universe began in a macrostate only compatible with very few microstates, relatively speaking. Because so many more microstates are accessible within the dynamical laws, the Universe will naturally evolve towards those macrostates consistent with more microstates.
>>10952177The increase in entropy happens locally and simultaneously. An apparent decrease in entropy of a macroscopic system happens simply because there's something locally exchanging energy with that system that you're ignoring. The entropy of organisms can appear to decrease only because the entropies of the neighboring medium and electromagnetic field simultaneously increase.
