TED-ED: The threat of invasive species - Jennifer Klos

The video explores the concept of invasive species, highlighting examples like the kudzu vine, Burmese pythons, and European rabbits. It explains how these species disrupt ecosystems by outcompeting native organisms due to a lack of natural predators and suitable climates. The video discusses the balance in ecosystems maintained by limiting factors and how human activities often introduce invasive species, either intentionally or accidentally. It concludes by questioning whether humans themselves could be considered an invasive species due to their widespread environmental impact.
