Who will survive? As always, the less glamorous, but very hardy Cockroaches. Cockroaches have outlasted doomsday asteroids and dinosaur extinctions. They can live for six weeks without food. They are not choosy about what they eat; they don’t need sugar, which other insects crave. They can subsist on grease, hair, or glue. They lack glamour and are ugly and unassuming. You usually don’t see them. They move fast.
