I live ridiculously frugal in a emerging economy country. It's not that I actively look to drop out of consumption, it's just that I lifestyle seemed to settle on this way of being. My entire cost of living is probably less than the cost of ownership of my small truck back home.

I don't consume things which use corn as an ingredient. I don't use seed oils. My food is mostly wild fish (local markets.) If Russia were unleash nuclear war, I probably wouldn't get hit.

I guess I would still be screwed if there were a global food catastrophe because it would affect me somehow.

No reason for this comment other than it's strange to see that the solutions on this list wouldn't apply to me.
