Ask a Question

  • This video provides historical context about lawns, the many ways that lawn maintenance can be damaging to our planet, and the ways that lawns are now regulated. 
  • Topics covered in the video include colonialism, conformity, classism, insecticides, herbicides, fertilizers, gas-powered lawn mowers, non-native grasses, monocultures, and water waste. 
Teaching Tips


  • This video brings up valuable content that is typically overlooked, especially given that there are more acres of grass than corn grown in the United States.
  • Students may also be surprised to learn how much water, fertilizer, and pesticides are sprayed onto lawns each year.

Additional Prerequisites

  • The video content ends at 9 minutes, 26 seconds. The last segment is an advertisement.
  • You may have to sit through commercials to view the video.


  • Science classes could use this video as a hook to discuss the nitrogen cycle, water ecosystems, eutrophication, biodiversity loss, and land use changes.
  • Social studies and civics classes could discuss new regulations that could prevent HOAs and cities from mandating lawns and lawn maintenance.
  • Economics classes could discuss the financial impacts of regulations that require residents to maintain lawns with chemicals, equipment, and water.
