Humanity and most of the latest iterations of Earthly flora and fauna? Maybe soon but inevitably yes. It's happened many times before. But "The World"? Not unless God decides to allow the Sun to go grossly unstable or something wicked and very big comes this way.

Mortal coils are just that, squishy and vulverable vehicles made up mostly of water. But not to worry. We are souls and we have bodies and squatters' rights to this realm on a very short term lease.
