“蓝绿空间（blue-green space）”离你家近不近，为什么影响幸福感？
Does nearby 'blue-green space' affect happiness, and why?
蓝绿空间指公园、河流、湿地等自然区域；住得离它们近的人更易散步放松、社交与运动，研究把这种可达性与更低的焦虑、更高的生活满意度联系起来。
Blue-green space means parks, rivers and wetlands; living near them makes walking, socializing and exercise easier, and studies link such access to lower anxiety and higher life satisfaction.

小区池塘里常见的“蜻蜓点水”其实在做什么？
What is a dragonfly really doing when it 'touches water' in the pond?
那是雌蜻蜓在产卵，把卵点进水中或水草上；幼虫在水里长大、吃蚊子幼虫，是池塘里免费的“灭蚊小卫士”和生态健康指示。
The female is laying eggs into water or plants; the larvae grow underwater eating mosquito larvae—free 'mosquito guards' and a sign of a healthy pond.

阳台上种一小盆薄荷或小番茄，为什么也算“亲近自然”？
Why does a pot of mint or cherry tomato on the balcony count as 'connecting with nature'?
看种子发芽、叶子舒展、开花结果，能让人每天留意生命的节奏；还能顺手摘来调味，把“买来的食物”变成“自己养出来的食物”。
Watching seeds sprout, leaves open and fruit form lets you notice life's rhythm daily; you can even pick some for cooking, turning 'bought food' into 'food you grew'.

下雨后地上为什么常有蚯蚓爬出来？
Why do earthworms often come out on the ground after rain?
雨水灌满土壤缝隙，蚯蚓在地下喘不过气，就爬到地面呼吸；它们翻土能让泥土更松软、更肥沃，是花园里的小园丁。
Rain fills the soil's gaps and worms can't breathe underground, so they surface to breathe; by tunneling they loosen and enrich the soil—little gardeners of the garden.
