Nowadays the way modern society is developing is being shaped by people's migration to large cities. In what ways is the migration to large cities affecting society? Has this become a positive or negative development?

Nowadays, urbanisation has changed 1people's lifestylespeople’s lifestyle thoroughly. Those living in suburbs or rural areas have gradually moved into central cities to find better opportunities, not only for a job but for 2accommodation, a better life and advanced facilitiesaccommodation, better life and advanced facilities. From my point of view, this modification has had more drawbacks 3forto communities. To begin with, two important reasons have led individuals to select sprawling cities as the best 4places to liveplaces for living. 5One is that they are more to find better job positions. Clearly, the branches of many multinational companies are located in large cities than in small cities. For example, 6a recent computer science graduatea fresh computer graduate living in a small village 7inof the USA is rarely able to find an appropriate career in his place, while by moving and living in Los Angeles, he will be able to apply 8tofor IBM, HP, Microsoft or other international corporations. Another benefit is that they can have a better lifestyle. Obviously, urban inhabitants can have 9more housing optionsmore options to inhabit, like living in skyscrapers or 10huge luxurious mansionsluxurious huge mansions which might not be found in 11suburbansuburb areas. 12The advancement of technology and modernisation are fewer in rural areas than those in the city. 13Finally, factoriesFinally factories, industries and other companies also attract 14labourerslabours and blue collar job seekers and that’s another reason many people move to large cities. This migration trend has changed the social structure and the economy of cities. The cities are expanding faster and the increasing population 15isare also creating many issues that were rare in the past. The huge population from 16different ethnicities, educational backgrounds, and religionsdifferent ethnicity, educational status and religion has created a mixed culture in the cities. Apart from the positive aspects, this mixed culture offers, many social and environmental problems are also being created because of that. In my view, this change of living condition has had more negative consequences than having more probable advantages. One obvious disadvantage is raising the density of air pollutants in cities. 17Unfortunately, using more private cars in metropolitan, dwellers are faced numerous heart and lung problems. In particular, had the government of Tehran, the capital of Iran, prohibited migration of rural people there, the rate of morbidity and mortality would have dropped fundamentally 18over the past three decadessince last three decades. According to medical officials’ report, just over 1940,000 people40000 of humans in Tehran died because of air pollution in 2014. Furthermore, 20traffic congestion has worsenedtraffic congestion has been deteriorated in urban areas. Admittedly, as the population grew, more private cars were to be used, leading traffic loads inflated far considerably and causing people to have more stress. However, controlling of immigration of villagers could reduce traffic jams, and citizens had less tension in their daily life. To sum up, although displacement of humans into major urban areas has had some credible benefits, its negative influences must not be forgotten. Increasing the density of air emissions and traffic congestion are the two prominent consequences that have jeopardised city dwellers’ lives because of mass immigration.
