Araucária, Paraná, Brazil

Araucária is a city located in the state of Paraná, Brazil. It has an estimated population of over 140,000 people and is known for its beautiful natural scenery and diverse flora and fauna. However, it is also known for its significant problem with light pollution.

Light pollution is a form of environmental pollution that occurs when excessive artificial light is introduced into the night sky. This type of pollution can have significant impacts on the natural environment, as well as on human health and wellbeing. In Araucária, the primary source of light pollution is the city's industrial sector, which includes several large factories and manufacturing facilities that operate around the clock.

The city of Araucária is situated in a region with a humid subtropical climate, characterized by hot summers and mild winters. The city's location near the Serra do Mar mountain range provides it with stunning natural landscapes and many opportunities for outdoor recreation. However, this also makes it vulnerable to the effects of light pollution, as the mountains block the city's view of the night sky.

Despite this, there are several landmarks in Araucária that are popular among tourists and locals alike, including the Parque Cachoeira, which features several waterfalls and hiking trails, and the Parque da Pedreira, a park with a large lake and a variety of recreational activities.

In terms of industry, Araucária is home to several large companies in the oil, gas, and chemical sectors, including Petrobras, Repar, and Dow Chemical. These companies have a significant impact on the city's economy, but they also contribute to its light pollution problem. The excessive lighting used by these facilities creates a glow that can be seen from miles away and has a significant impact on the city's natural environment.

To address this problem, the city of Araucária has taken several steps to reduce light pollution in the area. These include the implementation of new lighting technologies, such as LED lights, that are more energy-efficient and produce less light pollution. The city has also implemented regulations that require all new developments to adhere to strict lighting standards, with the goal of reducing the amount of artificial light that enters the night sky.

Despite these efforts, the level of light pollution in Araucária remains significant. A recent study found that the city has a mean zenithal sky brightness of 17.56 magnitudes per square arcsecond, which is considered to be moderately polluted. This level of light pollution has significant impacts on the city's natural environment, including the disruption of migratory bird patterns and the suppression of nocturnal animal activity.

Araucária is a beautiful city with a significant problem with light pollution. Its location near the Serra do Mar mountain range and the presence of large industrial facilities contribute to this problem. While the city has taken steps to address this issue, there is still much work to be done to reduce the impact of artificial lighting on the city's natural environment. It is essential that the city's residents, industries, and local government work together to find solutions that promote both economic growth and environmental sustainability.
