Prenatal air pollution exposure has adverse effects on the infant’s respiratory system. . what is the nature of the atmosphere. We live at the bottom of a thin layer of gases surrounding the earth called the atmosphere, which is divided into smaller spherical layers. In the troposphere, the layer closest to earth, about 75-80% of the earths air mass is found here.. Air pollution . -.  Harmful gases and tiny particles (like carbon monoxide, nitrogen dioxide and . sulphur. dioxide) when released into the air pollute the air. The smoke released from burning fuel, from factories and not to forget the motor cars are the major sources of air pollution. . Mrs. Beck . 6. th. grade . 2013. MAINTENANCE ACTIVITY.

Human activity is causing pollution in our air quality which affect animals, our environment and our health. Alternatives are on the rise to help decrease pollutants in our air which otherwise would increase environmental issues and our health. There maybe some obstacles in changing over how we produce energy but the benefits are worth the challenge in getting more people involved in using alternative resources..
