入侵物种为什么那么难"请走"？
Why is it so hard to "evict" invasive species?
一旦扎根并扩散，靠人工捕捞或农药往往只能压住、难以根除；它们繁殖快、藏得深，治理要长期投入且常要多种手段并用。
Once established and spread, manual capture or pesticides only suppress, rarely eradicate; they breed fast and hide well, needing long, combined efforts.

好心"放生"，为什么有时反而制造生态灾难？
Why can well-meaning "release" sometimes create ecological disaster?
放生的常是外来或养殖个体，到了野外没有天敌、还可能带病，挤占本地物种的生存空间；善意若不顾生态，反而会帮入侵物种"落地"。
Released animals are often alien or farmed, arriving without enemies and possibly with disease, crowding out locals; good intent without ecology helps invaders "land".

福寿螺、水葫芦，为什么能在中国水域泛滥成灾？
Why did apple snails and water hyacinth overrun Chinese waters?
它们繁殖极快、食性广，又缺少天敌；水葫芦盖住水面夺光夺氧，福寿螺啃食作物还传播寄生虫，治理起来很头疼。
They reproduce fast and eat widely with few enemies; hyacinth mats steal light and oxygen, apple snails damage crops and spread parasites—hard to control.
