Europe is different, though, with relatively well-developed regions. Although it appears that European nations occupy only one spot in the top ten cities, there are many urban cities with a population of millions, a depth that neither the United States nor Australasia can match.
As the current most populous city, London has many nicknames, and if it claims to be second, no other city dares to claim first.
Titles such as World's Financial Capital, World's Political Capital, World's Economic Capital, World's Industrial Capital, the Pearl of Europe, and Beacon of Humanity, among others, have adorned London with an unparalleled reputation.
At the same time, negative reputations like Capital of Smog and City of Exploitation are common drawbacks among highly populated cities.
Indeed, all highly populated cities face such issues. Fundamentally, current industry does not prioritize environmental protection, and its pollution and impact on the environment are substantial.
