Ozone is a gas that is constantly formed and reformed in our atmosphere. With the chemical formula O3, it is our defense against the Sun. Without the ozone layer, our Earth would become a barren wasteland on which little to no life could exist. UV radiation causes a host of problems for plants, animals, and humans including dangerous melanoma cancers.
