Biodiversity Is Collapsing Worldwide. Here's Why.

Ask a Question

  • This video explains biodiversity, its importance for life on Earth, and how it's being reduced by human activities and climate change. 
  • It gives specific examples of ecosystem disruptions and decreases in biodiversity in Colorado, Hawaii, and Australia. 
  • To address biodiversity loss, the video suggests habitat restoration, habitat preservation, supporting Indigenous communities, and reducing global warming. 
Teaching Tips


  • This video features great graphic design and does a nice job of explaining biodiversity.

Additional Prerequisites

  • The video content ends at 7 minutes, 41 seconds. The rest of the video contains a message from the creator.


  • Science and biology classes could use this as a hook or introduction to the biodiversity of life, genetics, evolution, phylogenetic trees, ecosystems, population dynamics, or biogeochemical cycles.
  • Social studies classes could use this resource when discussing the rights of Indigenous peoples, the plight of island nations, or in consideration of the idea that nature and other species should also have rights.

    • LS2: Ecosystems: Interactions, Energy, and Dynamics
      • MS-LS2-1. Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
      • MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
      • HS-LS2-2. Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
      • HS-LS2-6. Evaluate claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.
