Here in NYC there's an initiative of planting one million trees. And I'm all for planting more trees, but not just for the sake of it, and for the celebrity behind it to feel good about herself. If a home owner plants a tree there's a lot of planning involved. They analyze the perfect spot, how it matches the surrounding, if it's needed, etc. But in this situation it just plant one million trees for the heck of it. Cut a square, throw a bunch of dirt, the spot doesn't matter. It doesn't matter if it's in front of a stoop creating multiple bottlenecks in a busy block. The dirt gets all over, and half of the trees die anyway.
It really shows that human nature of not really thinking about your surrounding. In this case instead of causing pollution it's trees.
Random example, though not the best because if not a busy sidewalk.

In my personal opinion people should just not plant trees, instead they should create a community which can plan where its most suitable to plant them, who will take care of the trees and once they have answers to these questions then they should go ahead and plant trees.
