About Ozone

Ozone, a highly reactive gas molecule comprised of three oxygen atoms, is found naturally in the stratosphere. Although present only in tiny amounts, ozone is vital because it absorbs most of the harmful UV radiation emitted by the sun and prevents it from reaching Earth’s surface. 

Near the ground, ozone often is produced as a byproduct of burning fossil fuels. In this instance, ozone is very harmful. It can damage lungs and is harmful to other living things, such as plants.
