TED-ED: How long will human impacts last? - David Biello

The video explores the concept of the Anthropocene, a proposed epoch marking significant human impact on Earth's geology and ecosystems. It discusses how human activities, such as nuclear bomb testing and plastic production, have left lasting marks on the planet. The video also highlights the impact of human actions on biodiversity, leading to species extinction and environmental challenges. It emphasizes the importance of diversity in ecosystems for resilience and the potential future implications of current human choices.
