Vertical Forests, Can It Be Or Just A Crazy Idea


You've seen them. Those artists' renditions of futuristic skyscrapers, with trees growing in rooftop gardens or mid-building parks. City living is hard on the human psyche, so architects imagine that in the future, we'll have soothing green spaces built right into our high-rises.

Not so fast, environmental researcher-turned-journalist Tim de Chant writes on his blog. Trees often don't grow well on top of skyscrapers, De Chant explains, for a few crucial reasons.

First, it's much windier up there, which strips the tiny protective layer of air every leaf maintains. Some plants evolved to live in hot and windy climates and have adaptations to deal with this, but they aren't the tall, straight-trunked trees most often seen in drawings of green architecture.

Also, the weather really sucks. Temperatures are more extreme, and the velocity of rain, hail, snow and sleet is greater.

De Chant advocates spending time and money to preserve ground-level green spaces instead, which is a great idea. But what if, at the same time, we just ended up with skyscrapers growing the kinds of trees evolved for mountaintops and sea cliffs? That could be pretty cool:
