Human Impact on Biodiversity

The video discusses Earth's sixth mass extinction, driven by human activities such as climate change, habitat destruction, poaching, overfishing, and the introduction of invasive species. It highlights the impact of these activities on biodiversity, with many species at risk of extinction. The video also explores the potential of de-extinction technology to revive extinct species, emphasizing the need for human responsibility in protecting biodiversity.
