Ciudad de México, also known as Mexico City, is the capital of Mexico and one of the largest cities in the world, with an estimated population of over 21 million people. Its rich history, vibrant culture, and impressive architecture make it a popular destination for tourists and a bustling hub for business and industry. However, its growth and development have come at a cost, including a significant amount of light pollution.

The night lights of Ciudad de México are a sight to behold, with the city skyline illuminated by a seemingly endless sea of streetlights, office buildings, and residential homes. From the top of the Torre Latinoamericana, one of the tallest buildings in the city, one can see the sprawling metropolis stretching out in all directions, the bright lights creating a stunning contrast against the dark sky.

But while the night lights of Ciudad de México may be impressive, they also contribute to a significant amount of light pollution. According to a study conducted by the National Institute of Astrophysics, Optics and Electronics (INAOE), the city has a sky brightness of 32.1 mag/arcsec2, which is classified as severe light pollution. This level of light pollution can have negative impacts on both human health and the environment, including disrupting sleep patterns, interfering with wildlife behavior, and wasting energy.

There are several factors that contribute to the high levels of light pollution in Ciudad de México. One of the main factors is the city's dense population and urban sprawl. As the city has grown, so too has the number of buildings and streetlights, which all contribute to the overall brightness of the night sky. In addition, the city is home to several major highways and airports, which also generate a significant amount of light pollution.

Another factor that contributes to light pollution in the city is the habits of the people living there. Many residents of Ciudad de México have a culture of working late into the night and staying out late, which means that the city's lights are often on well into the early morning hours. In addition, many businesses and restaurants keep their lights on all night long, further contributing to the overall brightness of the city.

Despite these challenges, there are efforts underway to reduce light pollution in Ciudad de México. The city government has implemented several measures aimed at reducing the amount of energy consumed by streetlights, including using more efficient LED bulbs and installing motion sensors to turn off lights when not needed. In addition, several organizations are working to raise awareness about the negative impacts of light pollution and encourage individuals and businesses to take steps to reduce their impact on the night sky.

Ciudad de México is a bustling metropolis with a rich history and vibrant culture. Its night lights are impressive, but they also contribute to a significant amount of light pollution, which can have negative impacts on both human health and the environment. While there are challenges to reducing light pollution in the city, there are also efforts underway to address the issue and promote a more sustainable and healthy night sky for all.
