Ask AI: Write a summary about what the harmful effects of light pollution are AND what people can do to reduce light pollution.

Light pollution refers to the excessive or inappropriate use of artificial light. It can have harmful effects including disrupting ecosystems and wildlife, causing adverse health effects, affecting our sleep patterns, and wasting energy. It interferes with astronomical research by creating an artificial glow that outshines the stars and other celestial bodies. There are several measures that individuals and communities can take to reduce light pollution. These include using dark-sky friendly lighting that directs light downwards instead of upwards into the sky, minimizing the use of light, especially at night, and using lights with warmer colors. Advocating for or implementing policies that regulate outdoor lighting, and improving the efficiency of lights can also minimize light pollution. Awareness-raising about the harmful effects of light pollution can also be an effective way to tackle this issue. Taking these actions can lower light pollution levels, benefiting both the environment and human health.
