Prolonged exposure to such noise levels can lead to various health issues, including hearing loss, increased stress levels, and sleep disturbances. Moreover, the constant noise can disrupt wildlife habitats and behavior, affecting the biodiversity of urban ecosystems.

Light pollution, another consequence of industrial growth, is often overlooked but has significant environmental implications. Factories and manufacturing plants typically require extensive lighting to ensure round-the-clock operations. This artificial lighting can create a bright, illuminated environment that extends far into the surrounding areas. The excessive use of lights not only contributes to energy waste but also disrupts natural light cycles, affecting both wildlife and human activities. For instance, it can interfere with the natural behavior of nocturnal animals and impact the sleep patterns of humans, leading to potential health issues.

The constant operation of factories and manufacturing units also contributes to light pollution in the form of skyglow, where the night sky is illuminated by artificial light, even in areas far from the industrial sources. This phenomenon can have ecological consequences, as it can disrupt the natural darkness required for many species' survival and behavior. Additionally, the excessive lighting can create glare, which can be hazardous to drivers and pedestrians, increasing the risk of accidents and visual discomfort.

Addressing the noise and light pollution caused by industrial growth is crucial for sustainable urban development. Implementing stricter regulations and noise barriers can help mitigate the impact on nearby residents and wildlife. Adopting energy-efficient lighting systems and adopting practices that minimize light trespass can also contribute to reducing light pollution. By finding a balance between industrial needs and environmental sustainability, cities can ensure that economic growth does not come at the expense of the well-being of their residents and the natural environment.
