In Joy of Life, the reason for the extinction of mankind was the arrival of the Ice Age. In the novel, the arrival of the Ice Age led to rapid changes in the Earth's climate. The sea level rose, the land area decreased, and the ecosystem was severely damaged. Humans were almost extinct in this disaster, and only a few survivors survived around the world.

In Joy of Life, the reason for the extinction of humans was that humans threw nuclear bombs at each other, causing the Earth to fall into destruction. Nuclear radiation filled the atmosphere, and the remaining human civilization directly returned to the primitive era. This truth was mentioned in novels and television dramas.

Every time it was frozen, it would lead to the extinction of the creatures of the previous era. This extinction eventually led to nuclear war and the extinction of mankind by nuclear radiation. In addition, there was also a saying that advanced weapons and technology had led to the extinction of mankind. However, the specific details and background information were not mentioned in the search results provided, so a more specific answer could not be given.
