In cities today, light pollution and noise pollution are affecting our health and the environment.
In this essay, I will talk about the effects of these forms of pollution. When there is too much
light in an area, there is light pollution. Light pollution makes it difficult to see stars at night.
Most people don't think light is a big problem, but light pollution can cause headaches and
make people feel stressed. Many animals prefer to live in the dark, so light pollution is also
harmful to them. Some noise has a negative effect on people or nature. We call it noise
pollution. Transportation and machines cause the most noise pollution. Too much noise makes
people stressed, and it can affect their heart's health. It scares animals and makes it difficult for
them to communicate with each other... In conclusion, we should try to reduce light and noise
pollution. This will improve people's lives, help wildlife, and make our cities moré peaceful and
beautiful.
