Many futurists speculated that we would bring bright, shiny, and spotless technological wonders into space with us. In many ways they were right. But they were oh so wrong in others. Almost all of our permanent space stations have parks with trees and lakes in them. Places where we can enjoy nature by walking under real leaves or go for a good swim. Fish grow up there until they end up on someone’s plate with tartar sauce, and waterborne plants help filter both the water and the air. We just can’t live long periods of time separated from the nature that birthed us, so we bring it with.
