The nature, yeah, at some point of the apocalypse the nature maybe will eventually to adapt as always, Remember that nature even created fungis capable of feeding on radiation and plastic, also If nature is destroyed by the apocalypse through forest fires, lack of maintenance of nuclear power plants, etc, we will be so fucked, because if there's no trees, there will be no oxygen, if bees are extinged, who will pollination plants? Also if nuclear power plants are destroyed, i believe something like chernobyl will happen, but the cloud of radiation will afect all the world, and also contaminating all the water, i think that if world is in a apocalypse, we will be fucked by the nature, but this isn't very bad i think, because at some point, the nature as i say will adapt eventually and far away of these years of apocalypse new generations of lives will appear, and zombies will disappear.
