【日本の熊】ヒグマが“本州に来れない理由”…実は地理じゃなかった

The brown bear—a colossal presence that dominates the forests of Hokkaido. With its overwhelming size and strength, it is one of the strongest land animals in Japan. However, for some reason, brown bears do not exist on Honshu. Many people think it's because they are separated by the sea. But—that understanding is "half right and half wrong." Why doesn't the strongest animal expand its territory? Why doesn't it cross even if there's a "possibility of crossing"? 🐻What you'll learn in this video: ・The real reason why brown bears can't come to Honshu ・The history of division created by the Ice Age and the Tsugaru Strait ・Competition with the Asiatic black bear and the limits of the ecosystem ・The "invisible wall" created by human society ・The impact on the ecosystem if they were to come The current distribution is not a coincidence. It is a "necessary balance" resulting from the convergence of multiple conditions. If brown bears were to appear on Honshu— At that moment, Japan's nature would change dramatically.
