There are many ways civilization, as we know it, could end: nuclear war, major asteroid impact, or even a zombie apocalypse, and the hermit country of North Korea is planning to survive them all.
Along with math science, literature and the obligatory socialist ethics course, the isolated communist country is now preparing students for the collapse of civilization with daily classes warning them about the end of the world.
North Korea isn't the only country preparing for the end of the world, however. Earlier this year Swedish researchers published a report that outlined 12 global risks facing the planet that could potentially have an "infinite impact," according to Science Alert.
"[These events would be the] end of human civilization or even human life."
The Global Challenges Report gives violent AI robots a 1 in 10 chance of killing off all humans in the next 100 years simply because they don't need people to survive.
The other major obstacles to the survival of mankind include a global pandemic and extreme climate change, both at 5 percent. Less likely options for the extinction of mankind include ecological collapse, nuclear war, major asteroid impact, super volcano, and rogue nations like North Korea who are armed with nuclear weapons, according to the Global Challenges report.
"This makes extremely intelligent AI's a unique risk, in that extinction is more likely than lesser impacts. [But] an intelligence of such power could easily combat most other risks in this report, making extremely intelligent AI into a tool of great potential."
Their research focuses on finding patient zero, the person who first contracted the disease, along with understanding the transmission method and reproduction rate, according to The News Minute.
"The main consideration in a zombie epidemiology model is how many people a zombie can bite before it either runs out of victims or is destroyed."
Kim Jong-Un isn't taking any chances, however. He's instructed North Korean schools to start teaching his country's students how to survive the end of the world.
The survivalist prepper classes were announced as North Korea's saber rattling worsens and leaders in the communist regime continue to warn the world about an inevitable showdown with the U.S. and its allies.
The survival classes come as O Yong Ran, director of North Korea's Institute for International Studies, called the U.S. an empire of evil in a recent editorial in the state-run newspaper Rodong Sinmum, reports the Express.
"The US nature as man-killers has become all the more undisguised with the passage of time. As leopard never changes its spots, the brutal nature of the US can never change."
"We are ready to deal a merciless and annihilating blow to the enemy if they make even the slightest provocation."
