The population of Chennai city comprises of both Tamil and Telugus people. Its language is Tamil, and it is widely spoken, though English is also widely spoken. The major religion is Hinduism, with 81.3% of the population belonging to this faith. However, there are also other religions that have a presence in the city, including Christians, Muslims, and Jains. There are also a large number of minority groups that speak other languages.
The population of Chennai city is over nine million, and it is one of the most populous metropolitan areas in the country. This is due in large part to migrants from rural areas of the state. However, people from other regions in India also visit Chennai. In the last few weeks, Chennai has been suffering from water shortage, and four of the city's largest reservoirs are almost dried up due to the lack of rain.
Chennai is an important industrial hub in India. Historically, the city has been a port for the Bay of Bengal. It was also an important trading hub in South Asia. However, its modern economy has been centered around software development and electronics manufacturing, and it has numerous technology parks. Several foreign companies also have offices in Chennai. Other industries include automobiles, rubber, fertilizer, leather, and iron ore.
The main sources of pollution in Chennai are paved roads and brick kilns. These contribute to particulate matter, so the government needs to take steps to curb pollution by watering and sweeping roads. In addition, the government should provide subsidized CNG and LPG fuel to city commuters. Currently, many commuters in the city are unwilling to switch to cleaner fuels due to a lack of supply. Fortunately, the city has many walking and cycling paths that can help reduce the need for private vehicles.
