Why are we fascinated by apocalyptic stories? For some reason, we’re horrified and yet drawn to end-of-the-world scenarios. Here are five possible ways our planet will meet its doom.
Earth Tilt
Doomsday meteors have been part of our world’s myths forever. But what if a meteor hit earth that wasn’t large enough to cause complete devastation – but just big enough to change the tilt of the earth’s axis? Our solar system is very delicate balance: every body exerts a gravitational pull on every other body. If our planet’s axis shifts just a bit, it would soon wobble completely out of control, spinning towards the sun, the moon, another planet, or simply off into space. Not to mention the melting of the ice caps and death of nearly living thing in the interim.
Super Volcanic Eruption

Supervolcanoes are relatively new to scientists. There are only five known in the world. When the last supervolcano erupted in Indonesia in 1815, it changed the entire climate of the region, caused massive devastation, and killed nearly everyone in the area. That supervolcano is dwarfed by the one underneath Yellowstone National Park in California. Scientists predict when that volcano erupts, it will trigger the eruption of all the other supervolcanoes and a number of smaller ones. In other words, our planet will be one massive lava pool.
Nuclear Annihilation
Although the possibility of everyone dying in a nuclear winter seems remote, it wasn’t too long ago that it was a plausible scenario. The Zone of Alienation surrounding Chernobyl offers a chilling glimpse of what life after nuclear holocaust would look like. There are still nuclear warheads around the world unaccounted for, and terrorism is on the rise. Those quaint bomb drills of the 1960s don’t seem quite so antiquated now, do they?
Freeze to Death

There are two ways this scenario could come to pass. One is that our sun will eventually fizzle out. As it dies, our world will be become colder and colder, until eventually all life will die away. The other is that global warming will melt the ice caps, disrupting the natural heating and cooling flows of the planet. The results would be largely the same, but global warming would be much more likely to occur in our lifetime.
Biohazard

We may all die from an epidemic, triggered naturally or released by terrorists. There could be any number of diseases spread, from the mundane to the truly horrifying. Where nuclear wars were the fear of the Cold War, bio-terrorism is the fear in our era.
