"World politics and the society are chaotic, the environment worsens, how does the humanity continue many 100"

Sweetheart, I wish the schools and the media hadn't done such a good job of turning people away from Christianity. The Bible does have the answers to these questions. I suggest you find a good church. Tell the pastor what your worries are in these regards, and ask him to give you lessons from the Bible that will help you to understand what the problems are and that there is hope, so that you do not have to live in fear over this.
