While Gelidium seaweeds can be collected by gathering fragments washed ashore, mass production of agar requires steady, large quantities.10 Harvesters in New Zealand during WWII had to “walk beside a boat, waist to armpit deep in water and feel for the weed with their feet.” Handling large volumes of wet seaweed (which yields less than five percent agar) was challenging. Then as now, when Gelidium is harvested by scuba divers from rocky seabeds, collectors have to understand the life cycle of the algae, find the most likely locations for its growth, and prevent overharvesting to safeguard future yields.

在政府治理领域，数据是提升治理能力现代化的重要抓手。打破部门“数据孤岛”，整合公安、社保、卫健、教育、民政等多领域信息，能实现从出生、入学到就业、养老等事项的“一网通办”，真正让“高效办成一件事”成为常态。数据也让决策更科学、治理更精准。智能感知系统实时采集交通、气象、水文等数据，为风险识别、灾害预警和应急救援提供有力支撑，推动社会治理从被动响应向主动预防转变。
