The area burned so far is larger than most European countries. Entire towns have been razed, breeding grounds for various animals are destroyed and the fire in Kangaroo Island decimated the population of chlamydia-free koalas.
Even worse is that this mass clearing of forests will lead to a drastic increase in new growth which will lead to worse conditions for fires next year (since young plants with shallower root systems will dry out faster)
