Ep 3. Lost City of Life

In the third episode of Cosmos season 2, entitled "Lost City of Life," host Neil deGrasse Tyson takes us on a journey to discover the secrets of one of the most mysterious and unexplored regions on the planet: the deep ocean. With the help of cutting-edge technology and innovative scientific methods, Tyson uncovers a hidden world of life that has been untouched and undiscovered for millions of years.

Tyson begins by explaining that the deep ocean is the largest ecosystem on Earth, covering over 70% of the planet's surface. Yet, despite its vastness and incredible diversity of life, we have barely scratched the surface of what lies beneath the waves. To illustrate this point, he takes us on a plunge beneath the ocean's surface, where we discover a world of strange and fascinating creatures that have evolved to survive in the extreme pressures and temperatures of the deep.

With the help of a new generation of underwater submersibles, Tyson and his team are able to explore the depths of the ocean in ways never before possible. They discover a lost city of life, teeming with creatures that have never been seen by human eyes. From giant squids to glowing jellyfish, the deep ocean is a world of wonders that is just waiting to be explored.

As Tyson guides us through this hidden world, he also highlights the urgent need for us to protect the ocean and its inhabitants. The deep ocean is facing a range of threats, from climate change to overfishing, and it's up to us to take action to preserve this vital ecosystem for future generations. With stunning visuals, thought-provoking discussions, and cutting-edge science, "Lost City of Life" is a must-see episode for anyone who cares about the future of our planet.
