Washington — National Geographic scientists say they’ve discovered the world’s largest coral near the remote Solomon Islands in the Pacific Ocean — an undersea mass that is so big, it can be seen from space.

The man who found it, Manu San Felix, director of cinematography for National Geographic Society’s Pristine Seas, a program dedicated to marine conservation, says the giant organism measures 34 meters wide and 32 meters long and is “close to the size of a cathedral.”

“I see this as a living library that has the information of the conditions of the oceans for centuries,” he told reporters this week, underscoring it is a reminder of the need to better protect the ocean from global climate change.

Eric Brown, a Pristine Seas coral scientist, said the enormous coral species, Pavona clavus, is healthy and has “high reproductive potential,” making it essential to help other coral reef ecosystems recover from the damage of a warming ocean.

Corals “are very vulnerable ecosystems. So, it’s important for us to do whatever we can to protect these environments that are both small and mighty,” Brown said at a Tuesday press briefing to announce the find.

The announcement comes as world leaders gather for the United Nations climate conference, known as COP29, in Azerbaijan. Attendees are trying to agree on new mechanisms to finance a global energy transition to renewables and help nations like the Pacific Islands pay for the cost of adapting to rising oceans.

Pristine Seas is also encouraging nations to designate marine protected areas, or MPAs. The goal is to protect 30% of the world’s oceans by 2030.

Palau President Surangel Whipps Jr. is attending the summit. Palau has walled off 80% of its waters to development, while the nearby Pacific Island nation of Niue has designated 40% of its waters for protection.

“It cannot just be big countries. Small countries need to do their part,” he told VOA in an interview. “So, it’s all of us working together … protecting our oceans, because we know that healthy oceans are an important part of the ecosystem and important in regulating climate.”

Solomon Islands Prime Minister Jeremiah Manele agreed.

“Our survival depends on healthy coral reefs, so this exciting discovery underlines the importance of protecting and sustaining them for future generations,” he said in a press release.

But so far, the Solomon Islands has created a network of 79 designated ocean conservation areas — less than 1% of its exclusive economic zone. What’s more, its economy is largely dependent on forestry — the very industry that threatens the viability of coral through sedimentation.

“All that sediment is going onto a reef, and it’s smothering the reef, thereby preventing the corals from being able to feed, to grow, to reproduce,” Molly Timmers, Pristine Seas lead scientist on the Solomon Islands, said at the press briefing.

According to the Observatory of Economic Complexity, an online platform that seeks to visualize the distribution of international trade, the Solomons exported $308 million in rough wood in 2022, with $260 million of it going to China.

VOA asked Chief Dennis Marita, director of culture at the Ministry of Culture & Tourism, how the government can find a balance.

“Much of the logging activities are happening on the mainland” away from the coral, Marita said in an interview, but “there needs to be a serious awareness about the impacts of what’s happening in the logging industry to the marine environment.”

Marita sees this coral discovery as a way to attract researchers, biologists and tourists to bring in revenue to the small island nation of 740,000 people. Earlier this week, the Solomon Islands signed an agreement with China to provide visa-free travel between the two countries.

“Suddenly, people will start coming to the island, but then we need to be prepared for them, and also, we need to ensure that the coral is safeguarded,” Marita said.

Dr. Daniel Barshis of Old Dominion University’s Ecological Sciences Department in Norfolk, Virginia, said that idea has merit.

“I would imagine this discovery would draw tourists to the area, similar to how old-growth trees inspire folks to visit,” he told VOA via email.

“The fact that [corals] like this still exist is a reminder that coral reefs are still surviving and deserve us working as hard as we possibly can to save them from some of the worst-case scenarios if we don’t reverse course on greenhouse gas emissions as soon as possible,” said Barshis.
