However, this thin filter is enough to keep us safe and block most of the ultraviolet radiation coming from the sun. The smaller is the wavelength of ultraviolet light and can cause more damage to life, but is also more easily absorbed by the ozone layer. The problem lays at the places ...
The ozone layer is a thin concentration of ozone gas that exists in the stratosphere. The ozone layer has been damaged in the past due to human production of chlorofluorocarbons (CFCs) and other fluorinated gases. However, due to a ban on these chemicals, the ozone layer is regenerating....
