PS: Current humans probably won’t survive without internet for a month. May be a few will survive without going crazy and killing each other
During the start of COVID the supply chain of food got disrupted quite a bit. Large restaurant suppliers no longer had customers because the restaurants were closed and grocery stores didn't have enough supply to keep up with customers. However, I didn't even have to dig into my emergency rice stash at all, and I haven't heard of anyone else actually going hungry.
Do you think a larger disruption might cause a cascading effect, or how exactly would that play out? The COVID example appears to show the opposite: our food supply chain is rather robust.
Next pandemic will have countries hoarding masks and essentials even more early.
All that said, I was still talking about non-pandemic events.
