I don't think it takes a catastrophe to want to be more self-sufficient. I've been slowly heading that way. I'm not there yet, but I'm closer.
I've been learning about gardening, and doing so organically. Companion planting to fight pests, rather than using sprays. We have chickens for eggs, and to 'recycle' food waste from the table. Someday, I'd like to have rabbits for meat.
I buy local veggies to supplement what I get from the garden (especially last year, due to the drought). And I buy beef & pork from a local grass fed, free-range farming operation.
My credit card is paid off each month, and I'm getting better at focusing on needs than wants. I drive less, and plan my route to minimize gas use.
But I think most everyone here is headed in the right direction. You wouldn't be at BYC, otherwise. So no need to argue about whether the sky is falling or not. Even if it isn't, we should still all try to be more responsible in all aspects of our lives. And we can all improve in some way.
