That would be a wrong approach for this is not an essay paper. There is only one true answer to this question: urbanization is a blessing provided that it is managed or sustainable (this is what makes urbanization either wanted or unwanted) in a suitable way with certain approaches (these can then be discussed at length). If not managed it will certainly create cities and regions of conflicts of many kind (these will then be discussed at length). It's a curse as in cities where transportation patters are encouraging car dependency. This will make a community with social, environmental, and economical problems. Why is it a blessing? Needs of the communities may be catered with organized/anticipated/managed urbanization. You can provide for public with less investments in infrastructure. Biggest example is cities are engines of economic growth, and not the rural areas.
