Several European cities are replacing traditional white streetlights with red lighting to reduce light pollution and protect wildlife. In Copenhagen’s suburb of Gladsaxe, red LED lights have been installed along roads and cycle paths near bat habitats. The lights are placed at intervals that create darker gaps, allowing light-sensitive animals to cross safely without being exposed to predators and still providing enough visibility for people.
Studies have shown that white and green light can reduce bat activity, whereas red light has little to no effect. Studies conducted in the Netherlands found that light-sensitive bats remain active under red lighting. This makes red lighting a promising option for roads near wildlife habitats. It offers a practical solution that balances environmental protection with human safety, with the added benefits of lowering energy use and reducing maintenance needs.
歐洲數個城市正以紅色照明取代傳統白色路燈，以降低光害並保護野生動物。在哥本哈根郊區的格萊薩克瑟，靠近蝙蝠棲地的道路與自行車道沿途都設置了紅色 LED 燈。這些燈以間隔方式配置，形成較暗的空隙，讓對光敏感的動物能在不暴露於掠食者之下安全通行，同時仍為人們提供足夠的可見度。

研究顯示，白光與綠光可能會降低蝙蝠的活動，而紅光則幾乎沒有影響。於荷蘭進行的研究發現，對光敏感的蝙蝠在紅色照明下仍能保持活躍。這使得紅色照明成為野生動物棲地附近道路的一項具潛力選擇。它提供了一種平衡環境保護與人類安全的實用解決方案，同時具備降低能源使用與減少維護需求的額外優點。

In September 2025, Kaohsiung’s Beiling Elementary School became Taiwan’s first public Taigi (Taiwanese Hokkien) experimental primary school. Taigi used to dominate everyday speech in Taiwan, but its speaker base shrank after the promotion of Mandarin. According to the 2020 census, while 31.7 percent of Taiwan’s population identified Taigi as their main language, only 7.4 percent of children aged six to 14 did so. With the language in steady decline, it’s in schools like Beiling that the revival of Taigi finds its strongest hope. Employing Taigi as the primary medium across all subjects, Beiling pairs homeroom teachers with certified Taigi
