日本“熊患”加剧，伤亡数字创历史纪录，波及旅游业

Core Viewpoint - Japan is facing a significant increase in bear attacks, attributed to climate change and demographic issues, leading to heightened concerns in tourism and public safety [1][4]. Group 1: Bear Attacks and Statistics - Since April, at least 235 people have been injured in bear attacks across Japan, with 13 fatalities, marking a historical high in casualties [1]. - In a single day on December 4, multiple bear attacks resulted in injuries to at least 5 individuals, highlighting the severity of the situation [3]. - The Nagano Prefecture recorded its first winter bear attack since tracking began in 1977, indicating a troubling trend [3]. Group 2: Impact on Tourism - The bear attacks have adversely affected the tourism industry, with over 300 bookings canceled at a historic inn in Akita due to safety concerns [3]. - The presence of bears in populated areas has led to school closures and residents avoiding outdoor activities after dark, further impacting local tourism [3]. Group 3: Climate Change and Ecological Factors - Climate change is disrupting the ecological balance, with average temperatures in Hokkaido rising by 2.4 degrees Celsius over the past 30 years, leading to shorter hibernation periods for bears [6]. - A significant food shortage for Asian black bears is anticipated in 2025, as key food sources like beech and oak acorns are expected to fail, exacerbating the bears' search for food [6]. Group 4: Demographic Issues - Japan's declining population and increased abandonment of farmland are contributing to the blurred boundaries between bear habitats and human settlements, leading to more frequent bear encounters [6]. - The mechanization of agriculture has reduced the workforce needed to manage farmland, making it easier for bears to invade [6]. Group 5: Bear Population Growth - The bear population in Japan is increasing at an annual rate of 15%, with estimates rising from approximately 15,000 bears in 2012 to around 54,000 in the current year [7]. - Without intervention, the bear population could double in five years, posing a significant risk to human safety and local ecosystems [7].
