I'm going to need more than just some dead animals to convince me of an impending apocalypse. For one thing, instances of mass death among animal populations are hardly rare; they are only getting so much news coverage because of the timing of these events. They just happened to occur with a few days of each other, which causes people to form connections that aren't really there. It's called the clustering illusion; people see patterns where none exist. The events are far too widespread to have a single cause, and therefore, are unrelated.
However, if the apocalypse were to occur (and I wasn't just killed instantly) my plan is to fall back on my zombie apocalypse plan, more or less. Grab several of my friends, hit the gun shop up for some weaponry, and then take over Costco for food and fuel purposes. Hold out as long as I can.
