That is my concern. But the dimensional stabilizer regulates each inmate individually so that no one experiences anything that would be too difficult for them. There is no need to worry on that account, Doctor.
The animals and plantlife here that are below the cognizance par for inmates are considered to be innocent, and therefore are protected species. This system would never initiate an atmospheric change without ensuring that they will be comfortable -- in much the same way that I regulate each inmate's condition, really, but to a more complete degree.
