Survival is inevitably accompanied by death, and humanity and the Earth are no exception.As noted by the renowned British astronomer Martin Rees, the increasing sharpness of the double-edged sword of science has made it increasingly difficult to maintain the "health" of the Earth. Rees estimates that the probability of the Earth encountering a devastating disaster has risen from 20% a century ago to 50% today.This book selects and elaborates on the 10 most significant threats to humanity. It aims to enhance readers’ scientific knowledge, raise awareness of crises, foster environmental protection and peace concepts, and encourage collective efforts to safeguard the Earth, our shared home. Rich in content, this book prompts readers to reflect on life while reading, making it a classic science popularization book that offers new insights with each rereading.
