Singapore here, checking all the boxes. 200m from a neighborhood park with many trees, and ~700m from a GARGANTUAN park, Jurong Lake Gardens, over 4 km in length with many times that in pathways through gardens and around a lake.
London here: can see 12 trees within 30m from the back, 10 from the front; 50m from a neighbourhood park, 300m from Burgess Park (140 acres), probably 700m from Southwark Park (60 acres) (all of these are well tree-d)
Yes, Singapore is great for that. But to be fair with the other cities, it’s very hard _not_ to have abundant vegetation in tropical rainforest climate. Everything grows rapidly and stops at nothing in its way.
In other climates, like European ones, this becomes much more complex. Germany struggles even to keep its forests alive with long stretches of missing rain, higher temperatures, and new pests. Single trees in cities constantly die. Spain is in large parts a desert etc.
I really hope we find a solution/adapted plants to keep cities from heating up so much.
I can't see any trees from my window right now. But that's just because I'm in the groundfloor of a shophouse (in Singapore).
Yes, it's pretty green here.
Now, if we could ban street parking like Japan did [0], and perhaps take some more inspiration from Dutch traffic planning..
[0] Ideally we'd get the Gahmen out of the car parking business completely.
