pollution


Pollution is a very bad thing that makes the ozone layer get smaller. the type of pollution i am learning about is photochemical smog. This smog occurs when there is burning oil and burning coal. That is just two of them, whats in photochemical smog is Acid Rain which could cause Asthma, bronchitis, coughing and chest pain, some people try to stop all of the pollution by inventing new things.
