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.

However, if we planted the seeds at 1" intervals, it would only take 1/6 of one acre or an area about 70 x 100'. So, this is starting to look interesting. One person with an average size piece of dirt could plant the million trees.
Are those NY political hacks paying for this or giving tax discounts? Because if the sole requirement is the "planting", there's one heck of a deal here. Plus, think about all the delicious tiny shoots that the rats, squirrels and rabbits can eat.
