The third season of "Black Mirror" "Public Enemy" shows a "post-bee extinction era" scene. There was once an assertion that the day bees disappear, it will be the end of life on earth. Today, because bees spread most of the pollen on the earth, and without the process of pollen spreading, most plants will become extinct, and animals that rely on ingesting plants will also die one after another. In the end, humans will not be spared. The sixth episode is set in a future where bees are about to become extinct. Humans create mechanical bees to replace real bees to maintain the earth's ecology. It sounds far-fetched, but artificial bees have already been created in reality! Harvard University now has 60 artificial bees. The purpose of development is just like the setting in "Black Mirror" to prevent mass extinction of species. This also indicates that the survival status of bees as a species is somewhat dangerous. But if you’ve seen this episode of Black Mirror, you know how scary these bees can be.
