The city is not a concrete jungle, it is a human zoo.
No chains around my feet, But I'm not free.
I think a current understanding about urban behavior tells us that it's important that people get out and be able to get away from the concrete jungles and the dense environment where they live for their own mental well-being. If they don't do this, the costs in human loss and human sickness will be far greater than what we would be expending for these kinds of releases and open spaces.
Finding solitude in the concrete jungle is powerful and peaceful.
A city is a crazy concrete jungle whose people at the end of each day somehow make a small step ahead against terrible odds.
I don't like concrete jungles.
