Lesson outcome

I can describe why the ozone layer was nearly destroyed, but through a global community and international resolution it was saved.

Show transcript
The ozone layer protects life from harmful ultraviolet (UV) radiation from the Sun. Chlorofluorocarbons (CFCs) were once used, and when they entered our atmosphere reacted with ozone (O₃). Ozone levels decreased, but scientific communication led to action being taken to prevent further loss of ozone. The work of analytical scientists suggests the ozone layer is now reforming.
