   Of course (at least as far as Earth is concerned).   
      
   Earth receives a stream of entropy from the sun via solar radiation   
   (approximately the energy of the solar radiation impacting Earth divided   
   by the black-body temperauter of the Sun) and emits entropy into space   
   via radiation, approximately the same amount of energy from the sun   
   divided by the temperature of Earth as a black body.  Because that   
   temperature is much lower than that of sunlight, Earth generates   
   a lot of entropy.   
      
   The Second Law states that the change in entropy of any system has   
   to be larger than, or equal to,  the sum of the entropies going   
   over the boundariy of that system.  So yes, the Earth's entropy   
   could decrease, by quite a lot.
