日本の山にはオオカミが必要？！｜保水力と生態系の関係とは

Why do Japanese mountains need wolves? In this video, we explain the essence of "water retention" on a whiteboard, while also examining mountain ecosystems, dam policies, nature conservation, animal welfare, and the psychology of people who oppose the introduction of wolves. Based on our experiences living in the mountains, we carefully explain why "soil that retains water" is important and why building dams alone cannot solve the problem. I feel that in order to restore true water retention, we need the role of apex predators such as wolves, and the natural cycle itself. Recommended for those who are interested in the natural environment, water retention, ecosystem conservation, the limits of dams, rewilding, and the real-life experience of rural life and deep in the mountains. ▼Timestamps 0:00 Opening & What is "Evidence" 2:32 What is water retention 9:12 Are dams a waste? 21:40 Do we need wolves to regenerate forests? 33:31 Do people vote by instinct? 37:05 Bonus #WaterRetention #MountainLife #JapaneseForest #NaturalCycle #Wolf #Bear #Soil #Ecosystem #CountryLife #DeepMountainLife Human instincts haven't been updated for 100,000 years?!
