Description: This photo recorded the light pollution in downtown Montreal at night for a short time with a shutter speed of twenty seconds. The content of the photo contains two parts: buildings, and lighting. For buildings, only blue-gray tones are retained. And the bright orange is used in the lighting part to form a sharp contrast with the blue-gray buildings, thus highlighting the light pollution of the city.
Light pollution is excessive, misdirected, or inappropriate outdoor lighting. Too much light pollution washes out the view of the Universe, increasing energy consumption, interferes with astronomical research, disrupts ecosystems, and affects the health and safety of humans and wildlife. Light pollution can have as great an impact on the planet as levels of carbon monoxide and other airborne.
