Successor to the green heart.

I think we all know the green heart. A hard struggling piece of green that makes ferocious attempts to stay upright within heavily urbanized area. Trees, shrubs, forests, in short, a wonderful place to escape from the hectic.

But that's the green heart.

A while ago I was in the Hortus Botanicus in Utrecht (a lovely spot) and there I came across a surprising resemblance. Not with a heart, but with a lung.

Wouldn't it be great? A place where the oxygen is pure, filtered specifically for you? Basically, that's what plants do for us. Here so beautifully symbolized by plants. #milieu
