• This video explains how the hole in the ozone layer was formed, what was done to address it, and how society can apply these strategies to climate change.
• The ozone layer was predicted to be completely destroyed by 2050, but the Montreal Protocol to phase out ozone-damaging substances was eventually signed by every nation and today the ozone layer is expected to recover by 2065.

Positives

• This video interviews Dr. Solomon, a scientist who was instrumental in the discovery of what caused the hole in the ozone layer. 
  
• This video uses graphs and interviews to make the information more engaging and easy to understand. 
  

Additional Prerequisites

• There are ads before or during the video.
• Students should be comfortable reading graphs and should be familiar with the metric system. 
  

Differentiation

• The chemical reaction between CFC's and ozone is explained, so a chemistry class could use this as an example of a chemical reaction.
• The Montreal Protocol is a unique treaty and would be a great topic to cover in a social studies or government class. 
• Biology and science classes could use this video when discussing the electromagnetic spectrum, the atmosphere, the requirements of life on Earth, photosynthesis, food webs, and evolution.
