Many large cities have high levels of population, and this is one reason why they are so distinctive. Metropolitan areas are home to many people who seek greater economic opportunity. Pollution is an issue in many metropolitan areas due to high levels of industry. People who are poorer than others will be more at risk from HIV/AIDS. They must take part in potentially dangerous work to reach economic independence. The impact of poverty and AIDS on micro, mezzo and macro-social behaviors is devastating. The ecological footprint of people is directly affected by their actions and habits. It is crucial to promote sustainability by investing in renewable energy, as well as an efficient transportation infrastructure.
Research has previously shown that pollution from big cities is the main cause of environmental problems. The majority of major cities in the world still see a lot of rural and urban migration. Many types of pollution are a consequence of high levels of population in large cities. Plastics usage and disposal are much more prevalent in large cities than they are in rural areas or smaller towns. Plastic pollution continues to plague the urbanized world despite all the environmentalists and governments trying to eliminate it. Many see pollution as a negative consequence of urbanization. Many communities failed to find creative ways to reduce plastic pollution in their localities and their water supplies. The population of large cities draws a lot of residents from rural areas and smaller urban centres. This leads to unsustainable growth and an increase in pollution.
Sernau (2021) says that the most urgent problems facing large cities right now are the economic and social. Large cities’ instability and general disorder make it difficult for minority groups to contribute meaningfully to society. The most troubling aspects of urban living are insecurity, inequality and other forms. Overpopulation is the biggest issue that causes environmental harm. Urban air pollution can be caused by many factors. The main contributors to urban pollution are typically industrial and vehicular emissions (Sernau 2002). Because more people choose to live in cities, there is an increase in traffic on urban roads. Motor vehicle exhaust gas emissions can contaminate our environment. This is especially true if they are repeated. New Delhi is the city with the highest pollution levels (Rizwan and co., 2013). In a research done by Rizwa et al. Rizwa et al. (2013) found that Delhi is one of the most polluted places in the world. The indoor pollution was above the acceptable limit. Due to the city’s large population, and strain on sanitation services, it is widely believed that Delhi residents are more susceptible to various health problems. The research found that the city had interior pollution levels above acceptable standards due to its large traffic volume. Problem arises from the perception that there is no way to balance industry and health in Delhi. Delhi also has one of the most high rates of health problems related to air pollution. Many believe that environmental pollution can lead to adverse effects on the health of Delhiites due to overcrowding, crowded housing and poor living conditions.
