1. Unknown virus, zombie epidemic (very common, very European and American)
2. Technology progresses and then it is destroyed by the technology created by itself (actually, it is one aspect of human concern, with the advancement of technology, when machines can replace all human behaviors, At the same time, the idea of self is generated, then the existence of human beings will become less special. At the same time, human beings rely too much on technology, which leads to human beings no longer progressing, thinking begins to regress, physical energy begins to degenerate, and human beings may really die out. Personally, it is unlikely that human beings will perish because of this.)
