>> Genetic diversity is not a requirement for a species.
It is for any species on the edge of extinction. By definition, they are not adapting. Saddling them with the further burden of inbreeding isn't going to help.
Bacteria can also die in record numbers without much impact. If 1/2 of bacteria "children" die early due to genetic issues, little would change. But mammals invest much more energy into offspring than bacteria. Mortality rates matter.
