 The "severely polluted air and water" and allegedly "vast areas of decimated landscape" of Dnipro and Donetsk are considered by some to be an environmental crisis.Though exactly where in Dnipropetrovsk these areas might be found is not stated.Dnipro is a primarily industrial city of around one million people; in being such it has developed into a large urban centre over the past few centuries to become, today, Ukraine's fourth-largest city.
