Intelligent [sic] Design Creationists are stuck with a dogma that denies the role of amoral, purposeless natural forces in nature and must ascribe everything to the deliberate intent of a magic deity, whom they equate to the supposedly all-loving god of the Bible.
This means of course that the devastation the koalas are suffering right now is the result of this putative magic designer's intention. As the press release from the Leibniz Institute for Zoo and Wildlife Research, Berlin, Germany, reports:
Koalas are facing multiple environmental and health issues which threaten their survival. Along with habitat loss - accelerated by last year’s devastating bush fires – domestic dog attacks and road accidents, they suffer from deadly chlamydial infections and extremely high frequency of cancer. An international team of scientists led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) now demonstrate that a retrovirus invading the koala germline explains the high frequency of koala cancer. The results are reported in the journal Nature Communications.
