In many cities, planners build shops, schools, offices and homes in specific areas which may be separated from each other. Do you think the advantages outweigh the disadvantages?

Its disadvantages usually outweigh its advantages because it increases commuting, car dependence and social isolation, although limited separation is sensible for activities that create pollution, noise or safety risks.
