Here's an illustration I did for Ask Magazine, an art and science magazine for kids from Cricket Publishing Group. Interesting magazine, with lots of cool articles and illustrations. I had to draw a diagram showing the layers of construction that a green roof requires for an article about green roofs and living walls ( I love these names). Hopefully in a not so distant future we will have much more buildings carrying those oasis that can provide lots of benefits to people and urban wildlife alike. We will live in city jungles!
