As the average temperature of the Earth rises year by year, the habitat of polar bears, which live only in the Arctic, is moving southward, and the habitat of grizzly bears in the North and South America of the Arctic is moving northward. In recent years, there has been a change in the overlapping environment of the two species. The main difference between the two is that grizzly bears hibernate during the winter, but polar bears do not unless they have a nutritional deficit due to harsh environment.
Based on this fact, I imagined something such as, ""What would happen if a polar bear entered the habitat of a grizzly bear?"" And ""What would happen if a grizzly woke up too early when it is supposed to be in hibernation?"" The story involves white polar bears accidentally falling into the habitat of grizzly bears and because of its color difference, the white polar bear is discriminated against by the grizzly bears. Through this story, I wanted to focus on how the power of a group is dependent upon the population in that group.
