What comes to mind when you think of the high seas? Pirates, whales, giant squid and great white sharks?
Long the subject of stories and myths, life in the oceans beyond territorial waters is far from picture perfect. Under threat from climate change, acidification, overfishing, pollution and deep-sea mining, the area is now a focus for international scientists, who want to limit exploitation with ocean sanctuaries.
â€śExtraordinary losses of seabirds, turtles, sharks and marine mammals reveal a broken governance system,â€ť said Professor Callum Roberts, a marine conservation biologist at the University of York. â€śProtected areas could be rolled out across international waters to create a net of protection that will help save species from extinction and help them survive in our fast-changing world.â€ť
The researchers broke down the global oceans â€“ which cover almost half the planet â€“ and mapped the distribution of 458 different conservation features, including wildlife and habitats. They considered hundreds of scenarios for what a planet-wide network of ocean sanctuaries could look like, before putting together a plan for at least 30% to become ocean sanctuaries.
Our oceans cover 70% of the worldâ€™s surface and account for 80% of the planetâ€™s biodiversity. We can’t have a healthy future without healthy oceans – but they’re more vulnerable than ever because of climate change and pollution.
Tackling the grave threats to our oceans means working with leaders across sectors, from business to government to academia.
The World Economic Forum, in collaboration with the World Resources Institute, convenes the Friends of Ocean Action, a coalition of leaders working together to protect the seas. From a programme with the Indonesian government to cut plastic waste entering the sea to a global plan to track illegal fishing, the Friends are pushing for new solutions.
Climate change is an inextricable part of the threat to our oceans, with rising temperatures and acidification disrupting fragile ecosystems. The Forum runs a number of initiatives to support the shift to a low-carbon economy, including hosting the Alliance of CEO Climate Leaders, who have cut emissions in their companies by 9%.

The resulting report, titled 30Ă—30: A Blueprint For Ocean Protection, is a collaboration between the University of York, the University of Oxford and Greenpeace. It comes as the United Nations prepares to vote on an international legally binding instrument for the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction.
It matters, not only for the protection and preservation of our ecosystems, but also because marine life captures carbon at the surface of the high seas and stores it deep below, a mechanism that if lost would result in our atmosphere containing 50% more carbon dioxide.
At this yearâ€™s World Economic Forum Annual Meeting in Davos, the Friends of Ocean Action brought together entrepreneurs, innovators and scientists to discuss high-impact, large-scale solutions that could make the seas healthier.
Work like this, and the 30% plan, could help safeguard the future.
â€śWhatâ€™s so exciting about this research is that it shows that it is entirely possible to design and create a robust, planet-wide network of ocean sanctuaries,â€ť said Dr Sandra Schoettner from Greenpeaceâ€™s Protect the Oceans campaign. â€śThese wouldnâ€™t just be lines drawn on a map, but a coherent, interconnected chain of protection encompassing wildlife hotspots, migration corridors and critical ecosystems.â€ť
