If you could change one thing about your country, what would it be?

I am from a city called Pune. Pune is a metrapolis located in the state of Maharashtra. With a population of approximately seven million, the city has its fair share of problems associated with overpopulation; such as: pollution, traffic jams and shortage of real estate to name a few. If I were to change one thing about Pune, it would be the excess population of our city.
Over the past decade, the population of Pune has nearly doubled. This rise in population has resulted in a dramatic increase in pollution. Almost every household in the city now owns a car. Without any regulations regarding car emissions, air pollution has gone rampant. During peak traffic times, visbility is greatly reduced because of all the unchecked emissions. It is also becoming increasingly difficult to breathe as most of the air is heavily polluted. With the rise in population, the traffic has also increased considerably resulting in severe traffic jams throught the city. This causes major inconvenience as it now takes several hours to even commute small distances making it almost impossible to reach school, work etc on time.
Finally, the rising population has also overloaded Pune's drainage system. The city has been known for its efficient drainage system since the 19th century. However, unfortunately, no improvements have been made to it since. As a result, the system is severely lacking and the problem is further compounded by an increasing population. This has made leaking sewage water a common occurence in several parts of the city, which inturn has resulted in an exponential increase in the rate of malaria making the city a very unsafe place to live in.
Hence, to sum up, considering all the serious implications the growing population has on Pune, I would definitely change that aspect of my city and hope that the lower population would make it a much better place to live in.
