生态修复里的“参照生态系统”和“被动 vs 主动恢复”怎么选？
In restoration, how to choose between 'reference ecosystem' and passive vs active recovery?
参照生态系统提供恢复目标基准；在干扰已除、种子源尚存时“被动恢复”靠自然更新更省钱，而在严重退化、缺失物种时需“主动恢复”补植与土壤改良。
A reference ecosystem sets the target baseline; where stress is removed and seed sources remain, cheap passive recovery via natural regeneration works, while severe degradation needs active replanting and soil repair.

“持久性有机污染物（POPs）”为什么特别难对付？
Why are persistent organic pollutants (POPs) especially hard to deal with?
它们在环境中难降解、可长距离迁移、易在脂肪中富集并通过食物链放大（生物放大），即使源头禁用，存量仍会长期危害野生动物与人类健康。
They resist degradation, travel far, accumulate in fat and magnify up the food chain; even after a source ban, legacy stocks harm wildlife and health for decades.

从环境角度怎么量化“理性消费”——一件棉T恤的“水足迹”有多高？
How to quantify 'mindful consumption' environmentally—how high is one cotton T-shirt's water footprint?
一件普通棉T恤从种棉到成衣大约耗水 2000–3000 升，还伴随农药与印染污染。理性消费不是不买，而是少买、买耐穿、买二手，把每件衣服的“环境账”用足。
A typical cotton T-shirt uses roughly 2000–3000 L from farm to finish, plus pesticides and dye pollution. Mindful consumption means buying less, durable or secondhand, and wearing each item fully.

快时尚为什么被称为“环境杀手”，慢时尚怎么做？
Why is fast fashion called an 'environmental killer', and what is slow fashion?
快时尚靠低价高频上新，刺激过度购买与丢弃，带来巨量水耗、染整污染和填埋焚烧。慢时尚是买得少而精、保养久、支持可循环品牌与二手。
Fast fashion pushes cheap, frequent drops that drive overbuying and dumping, with huge water, dye pollution and landfill. Slow fashion is fewer, better pieces, cared for longer, plus circular and secondhand choices.

共享经济（如共享单车、工具租赁）一定能减碳吗？
Does the sharing economy (bike-sharing, tool rental) always cut carbon?
不一定。若共享提高了使用率、替代了私人购买或开车，则减排；但若制造维护成本过高、或刺激更多出行，反而可能增排。要看净效应。
Not always. It cuts emissions if utilization rises and replaces private ownership or car trips; but high manufacturing/maintenance cost or induced travel can increase them. Net effect matters.

和邻居共用割草机有什么好处？
What's good about sharing a lawnmower with neighbors?
两家不用各买一台，少用一台就更少挖矿、更省电，机器也用得更勤、不浪费。
Two homes needn't each buy one; one fewer machine means less mining and power, and it gets used more often instead of sitting idle.
