5) Cataclysmic Event

 With earthquakes, hurricanes, tsunamis, tornadoes, and more in its arsenal it goes without saying that cataclysmic events make their way onto this list. Cataclysmic events set to take place millions-billions of years from now are bent on wiping out most if not all life on earth. It isn’t certain whether these events will completely annihilate the human race, but the chances are rather high.

However, those who manage to beat the odds, whether it is due to luck or resilience will be forced to suffer through earth’s most brutal sate of decay and suffering. Those who manage to survive will have to adapt to the changes and chaos that occurs on earth.

This goes beyond being a challenge as stability is not yet met and finding a place among the rest of the animals could prove to be either the survival or extinction of mankind among the ever-growing scarceness of nature provided rations.
