In what context is light pollution a concern?

• A. Unwanted light that affects holiday lighting displays
• B. Excessive artificial light interfering with celestial visibility
• C. The lack of direct sunlight on plants
• D. Changes in natural weather patterns

Answer: (B)

Light pollution is primarily a concern due to excessive artificial light in the night environment, which significantly interferes with celestial visibility. This phenomenon diminishes our ability to see stars, planets, and other astronomical features in the night sky. Astronomers and stargazers are particularly affected, as the bright lights from cities and urban areas create a glow that obscures the clarity of the night sky, making it difficult to observe and study celestial bodies. Additionally, light pollution can disrupt natural ecosystems and affect wildlife behavior, as many species rely on natural light cycles for navigation, mating, and feeding. The bright artificial lights can confuse these creatures and lead to detrimental effects on their survival. The issue is not simply aesthetic; it has real implications for science, nature, and human health, as exposure to excessive artificial light at night can disrupt sleep patterns and circadian rhythms. In contrast, the other options either focus on light in a context that does not relate directly to pollution, such as holiday lighting displays or the lack of sunlight for plants, or suggest a connection to meteorological changes, which is not a direct consequence of light pollution.
