Do humans increase Entropy at a faster rate?

  1. May 22, 2015 #1
    Do systems further away from equilibrium increase entropy faster than a system with a high level of entropy and does this increase push the universe towards thermal equilibrium faster. Is there anything stopping the universe from reaching thermal equilibrium?

    Humans, and living things in general, are an organizing influence - i.e. "local" entropy changes tend to be negative.
    Overall, the net change in entropy is going to be positive, and it will be a bigger positive number than if the life were not present.
    On the scale of the Universe, the human impact entropy change is not detectable.

    I don't know of anything in mainstream models that opposes the laws of thermodynamics.

    Thanks for the response and this is the answer I was looking for. So what has a greater overall increase of entropy for the universe, low entropy dissipative system or a system with a higher level of entropy? Is this knowable?

    You mean "Does the rate of change in entropy depend on the current entropy level?"
    I think the answer is "it depends". You could probably set up two systems that fit your description and have the same rate of change.

    Low entropy mean large energy differences. Diffusion equation cannot works unlimited. Large energy differences makes flows that are more productive but have less entropy, because is organizing. Some say that the life is a more productive physical way to the total equilibrium.
