The Rich and Powerful Explore Our Planet High Seas

The full episode of “High Seas” in the Netflix series “Our Planet“, narrated by David Attenborough. The episode explores the wonders of the high seas, which are the vast, open waters beyond the boundaries of any country. The episode showcases the incredible diversity of life that thrives in these largely ungoverned, wild, and lawless areas.

The episode begins by discussing how the human population has more than doubled in the last 50 years and how it is essential to preserve the natural wonders to ensure the thriving of people and nature.

The episode then moves on to explore the lives of the largest animals on earth, the blue whales, which live far out to sea and roam every ocean from the tropics to the poles. The episode takes the viewers to the Gulf of California, Mexico, where a sanctuary for blue whales exists.

The viewers get to witness the most intimate moments of a blue whale mother and her calf. The episode highlights how blue whales were hunted relentlessly last century, and only a few thousand survived. But now, blue whales are protected, and their numbers are slowly increasing.

The episode then shifts to the Pacific Ocean off the coast of Costa Rica, Central America, where the spinner dolphins are starting to gather in great numbers. The viewers get to witness how the dolphins live in pods and are linked by complex social relationships.

They use a language of clicks and whistles to communicate with each other. The viewers also learn how the tuna rely on the dolphins to find food, and how the most numerous fish on the planet, the lantern fish, spend most of their time hiding in the deep.

The dolphins use echolocation, a type of sonar, to detect the lantern fish in the depths and drive them to the surface. The dolphins’ waste plays a vital role in recycling nutrients from the deep up to the surface, which helps to fuel the basis of all life in the open ocean.

The episode also showcases how phytoplankton, microscopic drifting plants, are the foundation of every food chain in the open ocean. They produce half the oxygen in the air we breathe and play a vital role in cloud formation.

The moisture evaporating from the ocean condenses around tiny particles created by the plankton, which combine to grow into colossal clouds that reflect the sun’s energy back into space, helping to protect the Earth from rising temperatures.

The high seas are the life-support system of our planet, driving the weather and climate, and transporting life-giving fresh water around the world.

Overall, the “High Seas” episode of “Our Planet” on Netflix provides a fascinating and educational glimpse into the wonders of the high seas and the essential role they play in sustaining life on our planet.
