Synopsis

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.

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.
