Question

Why do urban residents need to rely on food grown in rural areas?

Answer 1

Urban (city) areas rely on food from rural (countryside) areas because in urban citites, there aren't a lot of backyards. People stay in tall apart building built on concrete. There are a lot of streets and sidewalks. Downtown is an urban area. When you go downtown, you don't get much grass and certainly not much open area to grow crops.
