Light Pollution

Free English reading comprehension worksheet about light pollution
Light pollution is a big problem in modern cities. It is caused by too much artificial light at night. This light comes from streetlights, buildings, and other sources. Excessive light makes it hard to see the stars. Many children have never seen the Milky Way. Light pollution affects not only humans but also animals and plants. Birds can get confused by the bright lights in cities. They might fly in the wrong direction. Some plants need darkness to grow well. With constant light, their growth can be affected. People are starting to become more aware of this issue. Some cities are taking steps to reduce light pollution. They are designing street lamps that point downwards. This helps to keep the light where it is needed. Reducing light pollution also saves energy and money. Better lighting controls mean using less electricity. This is good for our environment too, as it reduces energy waste. Everyone can help reduce light pollution in their own ways. Homeowners can use curtains or blinds to keep light inside. Outdoor lights should be turned off when they are not needed. It is important to think carefully about how much light we use every day. Addressing light pollution is beneficial for our planet and all living beings. By making simple changes, we can enjoy more beautiful night skies. Together, we can make a change towards a better world.
