Ask a Question

Synopsis
  • This video from Hot Mess explains the remarkable success of the Montreal Protocol in banning the production of chlorofluorocarbons (CFCs) and other ozone-depleting substances. 
  • The video draws a comparison between our response to the ozone hole and the potential for similar action in the context of halting greenhouse gas emissions.
Teaching Tips

Positives

  • This video offers a rare and hopeful glimpse at what it looks like when environmental policy works on a global level. 
  • The video highlights the fact that the Montreal Protocol was successful, in large part, because it required wealthier countries to support economically disadvantaged countries in phasing out CFCs. 

Additional Prerequisites

  • The video begins with an advertisement. 
  • Though the ozone hole is just beginning to heal, the video may give the false impression that the ozone hole is nearly gone. 
  • Students will benefit from having some prior knowledge about climate change, greenhouse gas emissions, fossil fuels, and the Paris Climate Agreement. 

Differentiation

Scientist Notes
The Montreal Protocol, banning of CFC chemicals, is one of the rare times we've seen international policy affect the planet. While this video does give a rather optimistic view on the status of the ozone layer hole, it is, in reality, far from "saved" and has many years to go to reach pre-1980 levels. This resource is recommended for teaching.
