Pollution :- Pollution is when something is added to the environment that is harmful or poisonous to all living things. Smoke or dust in the air is a type of pollution as it is bad for the lungs when we breath in. Sewage in drinking water is another type of pollution, as it can make people ill because it contains germs and viruses.
This is true somthing we all need to consider. And look for ways to stop it or slow down.
