Some people prepare for Judgment Day, some others for a Zombie apocalypse. A few prepare for an alien invasion or when their government will start going dictatorship on them. I won’t discuss here these eventualities.
However I seriously advise you to increase your climate resilience. With a warming and weirding climate, as well as with increasing resource scarcity, all kinds of disruptions are due to occur sooner rather than later.
This is why the first step is to slash the amount of resources you use. Whether we are talking about basic commodities or gizmos and gadgets, consuming less is always a good idea.
