Good morning, everyone. Today we're going to look at how urban planning has evolved over the last century. In the early 1900s, cities often grew rapidly without much regulation, leading to overcrowded and unhealthy living conditions. Then, in the 1920s, zoning laws were introduced to separate residential areas from industrial ones. However, these laws sometimes created social divides. By the 1960s, planners began to focus on community needs, and in recent decades, sustainability has become a key priority. For example, many modern cities now prioritize green spaces and public transport over car use. So, as we see, the focus has shifted from mere efficiency to livability and environmental impact.
