Let’s say I’m going to Mauritius (an island country) to visit a friend. I’m there and then I get news that a long term SHTF world changing event has hit the USA making travel back to USA or and country impossible due to this event.

What could I do to survive this situation as a foreigner, would going back home even be possible? As a traveler this situation worries me.
