Because trees need time to grow and take roots. It's possible to plant big trees but it requires heavy machinery as root are large.
Usually there is not room in the soil (pipes etc), and asphalt/concrete prevent a tree to get water.
Also trees evolved to live in an ecosystem. A city is not an ecosystem.
And there also are roofs and walls and roads, so tree will just mitigate the problem.
It's feasible, but the cost is high, and it also implies giving up car space.
- samwillis 3y ago> A city is not an ecosystem. A city is an ecosystem, and we desperately need to treat them as one rather than try an obliterate all signed of none human life. > not room in the soil Not true in any sense, yes there are services under the ground but that is a tiny amount of usage. Roots can cause problems for hard surfaces, but the answers to that is more turf and planting, exactly as the article is proposing. > also implies giving up car space. Also only a good outcome, we need less cars stationary on streets using up valuable space.

- xyzzyz 3y ago> It's possible to plant big trees but it requires heavy machinery as root are large. Mature trees are also simply expensive by itself, as they require many years to grow. They are expensive to transport, and the transplant frequently fails to take hold, requiring buying another expensive tree, digging up the previous one and replacing it. This makes planting mature tree cost tens of thousands of dollars, compared to tens of dollars for planting saplings.
- voisin 3y agoSo plant small trees and invest in the future! The best time to plant a tree was 30 years ago, and the second best time is today.
- voisin 3y ago> A city is not an ecosystem. Maybe this is the problem. Humans like to pretend we are separate from the environment rather than a part of it, and the consequences of this lunacy are felt in every aspect of our lives, always to the negative.
- HPsquared 3y agoThere's not much natural in a city. Just decoration, really.

Some is better than none and you need some to have more.
- callalex 3y ago>always to the negative Only if you let yourself focus solely on the negative. For example, I don’t have to worry about a bear or really animal attacking me in the city. I can navigate safely without my own source of light. I am not going to get dysentery or cholera from the water supply or a neighbor’s runoff. I can travel great distances and participate in many communities without maintaining my own vehicle. I don’t have to worry about everything being constantly coated in a layer of dust. I could go on for a while more…
- Sharlin 3y agoYou are quite correct otherwise, but just about everything on Earth is an ecosystem. The word does not just refer to forests and meadows and grassland. Cities are surprisingly rich and complex ecosystems in fact. But they could be even richer.
