越冬候鸟为什么离不开湿地这一个个"驿站"？
Why can overwintering migratory birds not do without wetlands as "stopovers"?
长途迁徙耗能巨大，候鸟需要在湿地补充食物与体力；一旦驿站消失，整条迁徙路线就会"断链"，种群随之崩溃。
Long migrations burn huge energy, so birds must refuel at wetlands; lose a stopover and the whole flyway breaks, collapsing populations.

城市里的"小微湿地"为什么也很宝贵？
Why are small urban "pocket wetlands" also valuable?
即便只有池塘、沟渠大小，也能滞蓄雨水、降温、给蛙鸟昆虫留口粮；在城市里它们是容易被忽视却高效的"生态拼图"。
Even a pond or ditch stores rain, cools the air and feeds frogs, birds and insects—easily overlooked but efficient pieces of the urban ecological puzzle.

围填海为什么会让海岸在灾害面前更脆弱？
Why does coastal reclamation make shores more fragile against disasters?
填海抹平了红树林、滩涂这些天然缓冲带，波浪和风暴直接拍打硬化岸线；同时湿地丧失削弱了净化与碳汇功能，代价常被低估。
Reclamation erases mangroves and mudflats—natural buffers—so waves and storms hit hardened shores directly, while lost wetlands cut purification and carbon storage, a cost often undercounted.
