What percentage of people are affected by light pollution?

The statement that 80 percent of people are affected by light pollution highlights the significant prevalence of this issue in modern society. Light pollution refers to the excessive or obtrusive artificial light produced by urban development, which can disrupt ecosystems and obscure the night sky, leading to various adverse effects on human health and the environment.

Research has shown that a vast majority of the global population, particularly those living in urban areas, experience some form of light pollution. Factors such as city lights, street lamps, and illuminated billboards contribute to this phenomenon. As cities expand and technology advances, more areas become subject to artificial lighting, exacerbating the effects of light pollution.

By stating that 80 percent of people are affected, it underscores the widespread nature of the issue and the need for awareness and measures to mitigate its impact on natural environments and human activities. This statistic serves to emphasize the urgency of addressing light pollution and its consequences on global health and ecological balance.
