Positives

• The video provides good analogies and the animated content is engaging.
  

Additional Prerequisites

• Teachers will need to register for a free account to access the materials.
• The concept of an ecological footprint may be a novel concept for some, so be ready to discuss this further with students. 
• There is an answer key available for the worksheet.
  

Differentiation 

• There are related videos available for extended learning.
  
• Social studies and economics classes could discuss the social norms and built-in infrastructure that may make it harder for Americans to reduce their ecological footprints, even if they don't consume a lot of "stuff".
• Students could brainstorm ways of changing American culture and infrastructure to accommodate a more sustainable lifestyle with smaller ecological footprints.
• Other resources on this topic include this footprint calculator, this interactive data resource about the main causes of carbon emissions, this article about food waste, and this video about individual actions.
