How will the world end? No one knows, but BRYAN WALSH ’01 has devised eight of the most pressing existential threats to humanity in his book End Times (Hachette). Walsh explains what they are and how we might survive them on PAWcast, our monthly podcast. 

Walsh says: “The reality is that you can’t really ‘prepper’ yourself past the kind of catastrophes I’m talking about here. These are global ones that will last for years. There is no way to go out into the mountains with your own supplies and stay safe. It really requires us to come together as a species.”
