Hyderabad is a city located in the southern part of Pakistan's Sindh province, approximately 160 kilometers east of Karachi, the country's largest city. With a population of over 1.7 million people, it is the second largest city in the province and the eighth largest in the country. Hyderabad is known for its rich cultural heritage, traditional handicrafts, and famous landmarks.

At night, Hyderabad's skyline is lit up with a colorful display of lights, creating a vibrant and bustling atmosphere. However, this also leads to the issue of light pollution, which affects the city's residents and the environment. The primary cause of light pollution in Hyderabad is the excessive use of artificial lights for street lighting, commercial buildings, and residential areas. The use of high-intensity discharge lamps, such as mercury vapor and metal halide lamps, further exacerbates this issue.

The amount of light pollution in Hyderabad is estimated to be high, with the night sky often obscured by a bright orange glow. The International Dark-Sky Association has classified Hyderabad as a Level 6 zone, which indicates that the sky glow is significant and obscures many of the fainter stars. The high level of light pollution has a significant impact on the natural environment, affecting the migratory patterns of birds, the reproduction of nocturnal animals, and disrupting the circadian rhythms of humans.

Hyderabad is home to several famous landmarks that are illuminated at night, including the historic Pakka Qila fortress, the tombs of Talpur Mirs, and the Phuleli Canal Bridge. The Pakka Qila fortress, which was built in the 18th century, is one of the most prominent landmarks in the city, and its walls and towers are lit up at night, creating a stunning sight. The tombs of Talpur Mirs, which date back to the 18th and 19th centuries, are also beautifully illuminated, with intricate patterns and designs that are highlighted by the lighting.

The people of Hyderabad have several habits that contribute to the issue of light pollution. For instance, street vendors often use bright fluorescent lights to attract customers, while some residential areas use high-intensity lamps for security purposes. Additionally, many people in the city leave lights on all night, leading to unnecessary energy consumption and contributing to light pollution.

Hyderabad is also known for its textile and pharmaceutical industries, which contribute significantly to the city's economy. These industries often operate 24 hours a day, leading to the use of artificial lighting at all times. Furthermore, the city's rapid urbanization and population growth have led to the construction of new buildings and roads, which require lighting and further exacerbate the issue of light pollution.

Hyderabad is a bustling city that is famous for its rich cultural heritage, traditional handicrafts, and famous landmarks. However, its excessive use of artificial lights has led to the issue of light pollution, which has a significant impact on the environment and the well-being of its residents. The city's high level of light pollution is caused by the excessive use of artificial lights for street lighting, commercial buildings, and residential areas, as well as the use of high-intensity discharge lamps. The habits of the people, the textile and pharmaceutical industries, and the city's rapid urbanization have all contributed to the issue. It is essential to raise awareness about the issue of light pollution and take steps to reduce its impact on the environment and the city's residents.
