For those places that are coming back, or as in the case of Dublin being made more walkable, the environment especially will benefit as car trips can become shorter and, in many cases, can be replaced by transit and walking trips. We will also need fewer intrusions on undeveloped watersheds and the rural countryside. And, besides, walkable places are good for our health, too.
