It is bizarre how hostile to humans we build cities.

Reducing the urban heat island effect is the easiest countermeasure to mitigate some of the effects of climate change. A tree canopy is cheap with additional benefits to psychological well-being and air quality.

Cities are hostile to humans for the same reason barns are hostile to cattle. As long as we're willing to treat sentient beings as livestock, why would we expect ourselves to be treated any differently?

I like how simple it is

I see zero trees from my Tokyo apartment window :(

I live in a green city so i can see like ten or so from my window. It really does keep the heat down here in the tropics.

I can see more than 300 trees from out of my window. I feel like my stubborn refusal of being normal and following the rules brought me here and feel like I've secretly hacked the system. I also feel that more than half of the city dwellers wouldn't want to swap places with me after they learn there's bugs everywhere and no AC.

The 3-30-300 rule is an excellent benchmark. I'm more than a little surprised that the only German cities achieving this are in the Ruhr area around Essen. Really, wtf?

I can see three trees from every window in my home. Most are in my yard. But if I discounted those trees, I'd still see 3 trees from every window.

I live in a low-middle income neighborhood and I think it probably meets this 3-30-300 metric.

Great concept.

How is 30% tree coverage possible? The Street has to fully be covered and the house needs a garden. As long as trees are not on a roof, dense housing becomes impossible.

Tree lined sidewalks cover a lot of space once the trees become mature. And maybe dense housing with parks and green patches

[–] poVoq@slrpnk.net 6 points 2 weeks ago

With parks in between and maybe block designs that include interior shared green-spaces that seems very compatible with dense housing. On the contrary, dense housing uses less surface area per inhabitant (due to stacking apartments vertically) thus there is more space left for trees in between.
