What would happen if every human suddenly disappeared? - Dan Kwartler
TED-Ed・2 minutes read
Human settlements significantly influence the Earth's geological record, with the absence of humans resulting in immediate consequences like malfunctioning oil refineries and flooded underground rail systems. Over time, urban infrastructure deteriorates, leading to collapsed skyscrapers, eroded streets, and flooded tunnels turning into urban rivers, with imported plants thriving and altering ecosystems in the post-human world.
Insights
- Human settlements have a significant and long-lasting impact on Earth's geological record, showcasing the profound influence of human activity on the planet's landscape and ecosystems.
- The absence of humans results in immediate consequences such as malfunctioning oil refineries causing extensive fires and abandoned drainage pumps leading to flooding, highlighting the critical role of human intervention in maintaining urban infrastructure and preventing environmental disasters.
