It pokes fun at the city, the removal of nature – some of these streets with trees that live in these little squares of soil. But we forget that under this there are roots and sewers and below them there is more soil, and subways, and Internet cables, and fossils, and ancient buried civilizations, and then magma and stuff. I studied geology in college; learning about the Earth is a good foundation to understand people and that time is an axis and our point on it is a pinprick. Unfortunately, the Earth is like a balloon that can be popped, or a hot liquid ball inside of a shell inside of a balloon, and cows and ocean are on top of it.
