An experiment shows that "mouse paradise" is an experiment conducted by Israeli behavioral scientists on the influence of excessive population density on social behavior and reproductive health.
Why? Kalman (the person in charge) put a large number of mice in a narrow space, "and provided them with sufficient food and water resources." However, the space for increasing the number of rats and mice is becoming more and more crowded, which eventually leads to "abnormal social behaviors of rats, including hobbies, loneliness, baby aggression and weak fertility rate".
At the beginning of the experiment, rats and mice were divided into several fields by themselves because of adequate food, and began to establish social relations and social classes, and some "leaders" and "followers" appeared, forming different social circles. In the middle of the experiment, with the formation of social hierarchy, some rats began to have physical and mental problems, such as insomnia, depression and anxiety. The experimenter also noticed that low-level mice were more likely to get sick than high-level mice. At the end of the experiment, most rats had various health problems, such as tumor, osteoporosis and immune system disorder.
The "experimental conclusion" perfect paradise is over. "Environmental pressure and resource limitation caused by overpopulation" When there are too many rats, the space becomes crowded with living resources between them. "All cities will become limited", which leads to intensified competition and contention between exhibitions and serious pressure between exhibitions. "Social behavior and reproductive behavior will change." They become irritable and stick to their territory (even young rats will be attacked). No more socializing, no more breeding.
Conclusion: This conclusion has aroused people's reflection and discussion on human society, especially the social problems of urbanization and urban poor winning. However, the experimental results have not been widely recognized. Some people think that it has some problems in experimental methods, or it is just a simple model, which cannot accurately reflect the complexity of human society.
But: isn't the inexplicable correspondence more worth thinking about? Do not stop thinking!
