Pollution is when something is added to the environment that is harmful or poisonous to people, animals and other living things. Smoke in the air from factories is a type of pollution as it is bad for your lungs when you breathe it in. Sewage in drinking water is another type of pollution as it can make you unwell if you drink it because it contains germs and viruses. People living next to a building site where there is too much noise can become sick as they cannot sleep or relax. We call this noise pollution.
