As if the end of the Mayan calendar wasn¹t enough to have you worrying about mankind¹s existence, now another possible apocalyptic event is on the horizon ‹ and it¹s based on science!

Scientists report there¹s a ³super volcano² hidden near the same location where the notorious Mount Vesuvias eruption of 79 A.D. occurred and killed thousands of Pompeii residents. Only now this area of Italy is inhabited by 3 million residents, and the volcano is located in the tourist-heavy Campi Flegrei. This means an exponential number of casualties would arise if a similar event were to occur today
.
Making matters worse, the ash emitted into the air by such an event can cause global climate change and lead to catastrophic events which could impact people everywhere.
