Call to Earth Week
On October 8, 2026, the world comes together once again for CNN’s Call to Earth Day — the global day of action dedicated to protecting the planet we all share. This year’s theme, “Think Blue,” shines a light on the one force that connects every country, every coastline, and every community on Earth: the ocean.
From the coral reefs of the Pacific to the rivers and waterways that flow through our cities, the health of our oceans impacts all of us. Whether we live close to the sea or thousands of miles from it, oceans feed billions of people, regulate our climate and produce much of the oxygen we breathe. Despite these benefits, a number of human-caused factors threaten to stall the planet’s blue engine. Rising temperatures, overfishing and plastic pollution are just some of the issues threatening this fragile ecosystem.
That’s why this year, Call to Earth Day is inviting schools, organizations, families, and individuals around the globe to “Think Blue” and take action in support of our important waters.
Whether it’s organizing a beach or river cleanup, creating ocean-themed artwork, reducing single-use plastics, restoring marine habitats, planting mangroves, educating students about conservation, or simply pledging to make more sustainable choices, every action matters. Because protecting the ocean is not just the responsibility of coastal communities, it belongs to each and every one of us.

In July 2025, British adventurer, James Ketchell set sail from Gosport, England on an ocean adventure of nine months and 30,000 nautical miles. James was setting out to achieve his third circumnavigation of the globe and become the first person in history to do so via air, sea and land. He had already cycled around the world and was the first person to fly a gyrocopter around the world.
He completed the sailing journey in June of this year! Join in for a catch up with James to learn about this incredible sailing journey around the world and to check out some photos, videos and stories from along this epic journey!
Join us for a virtual field trip to the incredible Turtle Hospital in the Florida Keys and meet some sea turtles!
The Turtle Hospital opened its doors 1986 with four main goals: 1) rehab injured sea turtles and return them to their natural habitat, 2) educate the public through outreach programs and visit local schools, 3) conduct and assist with research aiding to sea turtles (in conjunction with state universities), and 4) work toward environmental legislation making the beaches and water safe and clean for sea turtles. The Turtle Hospital contains up-to-date equipment needed to perform a variety of surgeries on different species and sizes of sea turtles. There are 7 species of sea turtles throughout the entire world. Five of the seven are found in Florida: Green, Loggerhead, Leatherback, Hawksbill, and Kemp’s Ridley.
Join Fabien as he shares some of his ocean exploration adventures along with special guest Jason Link. Together they have created Oceanic, a marine life game which is currently launching via Kickstarted. A strategy game that should be in every classroom!
Fabien is the first grandson of Jacques-Yves Cousteau and spent his early years aboard his famous grandfather’s ships, Calypso and Alcyone, learning how to scuba dive on his fourth birthday. In June 2014, Fabien and his team of aquanauts embarked on Mission 31, the longest science expedition to take place at Aquarius, the world’s only underwater marine laboratory located in Florida and he’s currently developing PROTEUS™, the International Space Station of the Ocean off the coast of Curaçao.
Arzucan Askin is a National Geographic Explorer, OWUSS Scholar and conservation scientist with a passion for the protection of endangered marine wildlife. The best thing about her job is to be in the water: Her work has taken her across the world from studying blue whales in the Arctic, to removing ghost gear from shipwrecks in the Mediterranean, to monitoring coral reef ecosystems in Southeast Asia all the way to searching for deep sea sharks in the Indian Ocean.
When people think about Peru, the think about Machu Picchu, rainforests and deserts. But with over 3,000km of coastline, there an ocean world of incredible biodiversity. However, it’s under threat due to human activity. Join Daniel to learn about Peru’s Big 5 (dolphins, sharks, whales, turtles, rays) and the conservation efforts to protect them.
Daniel is the Hispanoamerica representative for Sustainable Ocean Alliance (SOA), a marine biologist, PADI Dive Instructor, Darwin200 and Peace Boat Ambassador. In 2015, he founded Cuidando el Mar, Peru’s largest ocean collective, and in 2017, he established SOA Perú, the first international SOA hub and the largest youth ocean leadership network in the country.
Join deep-sea explorer Victor Vescovo to learn what it takes explore the very deepest places on Planet Earth: the technology, team, training, and planning. Why do we do it, what did we find, and what do we hope to learn in the future?
Victor has skied to both poles and climbed the highest peaks on each continent. He is also an accomplished pilot of jet fixed-wing aircraft, helicopters and, most recently, manned submersibles. He is now the first person in history to have been to the top of all the world’s continents as well as the bottom of all its oceans.
After travelling 47,000 miles and completing 39 dives, the Five Deeps Expedition has reached its successful conclusion: the first manned descent to the deepest point of each of the world’s five oceans.
Just like people, corals need oxygen to survive, but our oceans are slowly losing oxygen as the planet warms. Join oceanographer Dr. Ariel Pezner on an adventure across the Caribbean, Eastern Pacific, and Great Barrier Reef to discover how corals are coping with this challenge and how scientists test what reefs of the future might be like. Through her research, we’ll meet some surprisingly tough corals that could unlock tools to help save reefs for generations to come.
