We have the opportunity to create the largest protected area on Earth: an Antarctic Ocean Sanctuary. It would ensure a safe home for future generations of animals, and protect the waters from industrial fishing vessels, currently sucking up the tiny shrimp-like krill on which all Antarctic life relies. The Antarctic ocean supports an abundance of incredible life: penguins, whales, fish, seals, and colossal squid. But a warming climate and expanding industrial fishing are threatening this vital ocean and its iconic creatures.
