First came the acid rain, initially most Feles blew it off as just bad weather. As time passed it was only getting worse, it reached a point where anything solvent that was exposed corroded down to nothing. At this point, it had polluted enough of the groundwater that the soil became contaminated beyond repair; this is when the real problems came. With the soil poisoned, the plants were the first to start dying off. Not long after, lacking nutrients any wildlife that had not already fallen victim to the rain were expunged.
