Can you see three trees?

A feel-good urban planning idea — can you see three trees from your window, do you live in an area with 30% tree cover, and are you within 300 metres of a park — somehow inspired exactly the kind of internet energy you’d expect: part civic concern, part geography fight, part comedy hour. The rule is spreading fast in cities from Florence to Colorado because it’s easy to understand and ties green space to better mental and physical health. But the big reality check is that many places still fail, especially on tree cover.

And the comments? Instant drama. One reader zeroed in on Espoo and basically said, “Calling this a city is generous,” arguing it feels more like a giant patchwork of car-dependent suburbs than a proper urban success story. That was the sharpest hot take in the thread: not just debating trees, but what even counts as a city. Others were less combative and more delightfully impatient, begging for interactive maps and photos so normal humans can actually tell what “passes” the test. Fair! As one commenter put it, three trees doesn’t even sound like that much.

Then came the comic relief. A commenter from northwest Scotland joked that missing tree data is probably because the local climate includes 140 mph winds and a season known as “January.” Another dropped the slogan-like line, “Beneath the pavement, the beach!” — turning a tree debate into poetic urban rebellion. In other words: people agree green space matters, but they’re absolutely going to roast the map, the cities, and the weather while discussing it.
