9种人类自毁的方式（Nine ways of human self-destruction） Nine ways of human self-destruction First of all it has nothing to do with Maya, long calendar or whatever. When it comes to the destruction of human civilization, we never lack of the threat from nature, including asteroid impacts and super eruptions - but in the human can play dead himself, who needs a natural disaster? Here are nine ways humans can be destroyed. 1. Nuclear Armageddon The cold war ended long ago, but the nuclear shadow still hangs over the human race. In fact, the worst is yet to come. The most terrifying thing about nuclear weapons is not its enormous power, but the technology to build nuclear weapons. More countries to master nuclear weapons technology is only a matter of time (Iran and north Korea is now the best example of this), and the biggest threat is that in the information age, we are going to want a bomb technology easier than in the past a lot, not only as the main body of the government, is also likely to get even. The most difficult thing, from theory to practice, is to get enriched uranium, which is easier said than done. But once the molecular self-assembling nano-era comes, the enrichment of enriched uranium may be as simple as heating food in the microwave. With the previous content as the basis, now we can discuss how many bombs would be needed to destroy the entire human civilization. There are models that show that 100 15-kiloton bombs would allow the earth to enter the nuclear winter. The initial blast and subsequent radiation of the nuclear bomb, depending on the location of the target, could kill between 3 million and 16 million people. And after the nuclear winter, the surviving humans will experience at least 10 years of famine, which could result in billions of light that a famine at this time of the death of the population - no matter how many people left the glory of human civilization is a thing of the past. 2.
