it is curious the similarities between

-religious cataclysms

-natural cyclic cataclysms

-curreent movie themes

You will eat the bugs, have nothing and be happy.

After the past natural cataclysm:

-there were no possessions to be had

-there were no food animals available in areas far from the coasts

-survivors were happy to be alive

short bus replication of natural cyclic events.
