Unfortunately, pollution is like air: it’s everywhere! pollution is the introduction of harmful substances into the environment that can cause damage and harm to humans, animals, and the environment. it takes on a number of different forms, from chemicals and garbage to something as seemingly innocent as light or noise.

2pollution comes from a variety of sources. in addition, it alters, changes, and even destroys a variety of places. for example, exhaust from cars pollutes the air. when it rains, runoff from fertilizers and pesticides, which farmers use to crops grow, can pollute the water in oceans, rivers, lakes, and streams. garbage dumped in landfills is not only an eyesore, but also a source of harmful gases that can damage the earth’s atmosphere. light pollution, which comes in the form of bright streetlights or signs, disrupts the view of the night sky. noise pollution caused by cars, trucks, and machines interrupts the natural sounds of the world around us, such as birds singing or leaves rustling.
