The Svalbard Global Seed Vault preserves more than one million of the world's seeds deep inside Platäfjellet Mountain.
"Before, we trusted the permafrost. We do not trust the permafrost anymore."
Art installations on the building's rooftop and front façade glimmer like diamonds in the polar night, but it is what lies buried deep inside the frozen rock, 475 feet from the building's entrance, that is most precious. Here, in the Svalbard Global Seed Vault, are backup copies of more than a million of the world's agricultural seeds.
Inside the vault, seed boxes from many gene banks and many countries. "The seeds don't know national boundaries," says Kent Nnadozie, the UN's Secretary of the International Treaty on Plant Genetic Resources for Food and Agriculture.

The Svalbard vault -- which has been called the Doomsday Vault, or a Noah's Ark for seeds -- preserves the genetic materials of more than 6000 crop species and their wild relatives, including many of the varieties within those species. Svalbard's collection represents all the traits that will enable the plants that feed the world to adapt – with the help of farmers and plant breeders – to rapidly changing climactic conditions, including rising temperatures, more intense drought, and increasing soil salinity. "We save these seeds because we want to ensure food security for future generations," says Grethe Helene Evjen, Senior Advisor at the Norwegian Ministry of Agriculture and Food .
A recent study in the journal Nature predicted that global warming could cause catastrophic losses of biodiversity in regions across the globe throughout this century. Yet global warming also threatens the permafrost that surrounds the seed vault, the very thing that was once considered a failsafe means of keeping these seeds frozen and safeguarding the diversity of our crops. In fact, record temperatures in Svalbard a few years ago – and a significant breach of water into the access tunnel to the vault -- prompted the Norwegian government to invest $20 million euros on improvements at the facility to further secure the genetic resources locked inside. The hope: that technology can work in concert with nature's freezer to keep the world's seeds viable.
"Before, we trusted the permafrost," says Hege Njaa Aschim, a spokesperson for Statsbygg, the government agency that recently completed the upgrades at the seed vault. "We do not trust the permafrost anymore."
The Apex of the Global Conservation System
More than 1700 genebanks around the globe preserve the diverse seed varieties from their regions. They range from small community seed banks in developing countries, where small farmers save and trade their seeds with growers in nearby villages, to specialized university collections, to national and international genetic resource repositories. But many of these facilities are vulnerable to war, natural disasters, or even lack of funding.
"If anything should happen to the resources in a regular genebank, Svalbard is the backup – it's essentially the apex of the global conservation system," says Kent Nnadozie, Secretary of the International Treaty on Plant Genetic Resources for Food and Agriculture at the United Nations, who likens the Global Vault to the Central Reserve Bank. "You have regular banks that do active trading, but the Central Bank is the final reserve where the banks store their gold deposits."
Similarly, farmers deposit their seeds in regional genebanks, and also look to these banks for new varieties to help their crops adapt to, say, increasing temperatures, or resist intrusive pests. Regional banks, in turn, store duplicates from their collections at Svalbard. These seeds remain the sovereign property of the country or institution depositing them; only they can "make a withdrawal."
The Global Vault has already proven invaluable: The International Centre for Agricultural Research in the Dry Areas (ICARDA), formerly located outside of Aleppo, Syria, held more than 140,000 seed samples, including plants that were extinct in their natural habitats, before the Syrian Crisis in 2012. Fortunately, they had managed to back up most of their seed samples at Svalbard before they were forced to relocate to Lebanon and Morocco. In 2017, ICARDA became the first – and only – organization to withdraw their stored seeds. They have now regenerated almost all of the samples at their new locations and recently redeposited new seeds for safekeeping at Svalbard.
Rapid Global Warming Threatens Permafrost
The Global Vault, a joint venture between the Norwegian government, the Crop Trust and the Nordic Genetic Resource Centre (NordGen) that started operating in 2008, was sited in Svalbard in part because of its remote yet accessible location: Svalbard is the northernmost inhabited spot on Earth with an airport. But experts also thought it a failsafe choice for long-term seed storage because its permafrost would offer natural freezing – even if cooling systems were to fail. No one imagined that the permafrost could fail.
"We've had record temperatures in the region recently, and there are a lot of signs that global warming is happening faster at the extreme latitudes," says Geoff Hawtin, a world-renowned authority in plant conservation, who is the founding director of -- and now advisor to -- the Crop Trust. "Svalbard is still arguably one of the safest places for the seeds from a temperature point of view, but it's actually not going to be as cold as we thought 20 years ago."
A recent report by the Norwegian Centre for Climate Services predicted that Svalbard could become 50 degrees Fahrenheit warmer by the year 2100. And data from the Norwegian government's environmental monitoring system in Svalbard shows that the permafrost is already thawing: The "active layer," that is, the layer of surface soil that seasonally thaws, has become 25-30 cm thicker since 1998.
Among the 35 depositors were several bringing their seeds to Svalbard for the first time, including the Cherokee Nation, which deposited nine heirloom seed varieties that predate European colonization.
Though the permafrost surrounding the seed vault chambers, which are situated well below the active layer, is still intact, the permafrost around the access tunnel never re-established as expected after construction of the Global Vault twelve years ago. As a result, when Svalbard saw record high temperatures and unprecedented rainfall in 2016, about 164 feet of rainwater and snowmelt leaked into the tunnel, turning it into a skating rink and spurring authorities to take what they called a "better safe than sorry approach." They invested in major upgrades to the facility. "The seeds in the vault were never threatened," says Aschim, "but technology has become more important at Svalbard."
Technology Gives Nature a Boost
For now, the permafrost deep inside the mountain still keeps the temperature in the vault down to about -25°F. The cooling systems then give nature a mechanical boost to keep the seed vault chilled even further, to about -64°F, the optimal temperature for conserving seeds. In addition to upgrading to a more effective and sustainable cooling system that runs on CO2, the Norwegian government added backup generators, removed heat-generating electrical equipment from inside the facility to an outside building, installed a thick, watertight door to the vault, and replaced the corrugated steel access tunnel with a cement tunnel that uses the same waterproofing technology as the North Sea oil platforms.
To re-establish the permafrost around the tunnel, they layered cooling pipes with frozen soil around the concrete tunnel, covered the frozen soil with a cooling mat, and topped the cooling mat with the original permafrost soil. They also added drainage ditches on the mountainside to divert meltwater away from the tunnel as the climate gets warmer and wetter.
New Deposits to the Global Vault
The day before COVID-19 arrived in Norway, on February 25th, Prime Minister Erna Solberg hosted the biggest seed-depositing event in the vault's history in honor of the new and improved vault. As snow fell on Svalbard, depositors from almost every continent traveled the windy road from Longyearbyen up Platåfjellet Mountain and braved frigid -8°F weather to celebrate the massive technical upgrades to the facility – and to hand over their seeds.
Among the 35 depositors were several bringing their seeds to Svalbard for the first time, including the Cherokee Nation, which deposited nine heirloom seed varieties that predate European colonization, and Israel's University of Haifa, whose deposit included multiple genotypes of wild emmer wheat, an ancient relative of the modern domesticated crop. The storage boxes carried ceremoniously over the threshold that day contained more than 65,000 new seed samples, bringing the total to more than a million, and almost filling the first of three seed chambers in the vault. (The Global Vault can store up to 4.5 million seed samples.)
"Svalbard's samples contain all the possibilities, all the options for the future of our agricultural crops – it's how crops are going to adapt," says Cary Fowler, former executive director of the Crop Trust, who was instrumental in establishing the Global Vault. "If our crops don't adapt to climate change, then neither will we." Dr. Fowler says he is confident that with the recent improvements in the vault, the seeds are going to remain viable for a very long time.
"It's sometimes tempting to get distracted by the romanticism of a seed vault inside a mountain near the North Pole – it's a little bit James Bondish," muses Dr. Fowler. "But the reality is we've essentially put an end to the extinction of more than a million samples of biodiversity forever."

Maybe it feels like a core human instinct to demonize bugs as gross. We seem to try to eradicate them in every way possible, whether that’s with poison, or getting out our blood thirst by stomping them whenever they creep and crawl into sight.
But where did our fear of bugs really come from? Jessica makes a compelling case that a lot of it is cultural, rather than in-born, and we should be following the lead of other cultures that have learned to live with and appreciate bugs.
The truth is that a healthy planet depends on insects. You may feel stung by that news if you hate bugs. Reality bites.
Jessica and I talk about whether learning to live with insects should include eating them and gene editing them so they don’t transmit viruses. She also tells me about her important research into using genomic tools to track bugs in the wild to figure out why and how we’ve lost 50 percent of the insect population since 1970 according to some estimates – bad news because the ecosystems that make up the planet heavily depend on insects. Jessica is leading the way to better understand what’s causing these declines in order to start reversing these trends to save the insects and to save ourselves.
A company called Second Sight made an implant that partially restored vision to people who'd been blind for decades. But when Second Sight pivoted, it stopped servicing its product, leaving many in the dark.
The Argus II uses the implant and a video camera embedded in a special pair of glasses to provide limited vision to those with retinitis pigmentosa, a genetic disease that causes cells in the retina to deteriorate. The camera feeds information to the implant, which sends electrical impulses into the retina to recapitulate what the camera sees. The impulses appear in the Argus II as a 60-pixel grid of blacks, grays and whites in the user’s eye that can render rough outlines of objects and their motion.
Smartphone and computer manufacturers typically stop issuing software upgrades to their devices after two or three years, eventually rendering them bricks. But is the smartphone approach acceptable for a device that helps restore the most crucial sense a human being possesses?
Ross Doerr, a retired disability rights attorney in Maine who received an Argus II in 2019, describes the field of vision as the equivalent of an index card held at arm’s length. Perk often brings objects close to his face to decipher them. Moreover, users must swivel their heads to take in visual data; moving their eyeballs does not work.
Despite its limitations, the Argus II beats the alternative. Perk no longer relies on his guide dog. Doerr was uplifted when he was able to see the outlines of Christmas trees at a holiday show.
“The fairy godmother department sort of reaches out and taps you on the shoulder once in a while,” Doerr says of his implant, which came about purely by chance. A surgeon treating his cataracts was partnered with the son of another surgeon who was implanting the devices, and he was referred.
Doerr had no reason to believe the shower of fairy dust wouldn’t continue. Second Sight held out promises that the Argus II recipients’ vision would gradually improve through upgrades to much higher pixel densities. The ability to recognize individual faces was even touted as a possibility. In the winter of 2020, Doerr was preparing to travel across the U.S. to Second Sight’s headquarters to receive an upgrade. But then COVID-19 descended, and the trip was canceled.
The pandemic also hit Second Sight’s bottom line. Doerr found out about its tribulations only from one of the company’s vision therapists, who told him the entire department was being laid off. Second Sight cut nearly 80% of its workforce in March 2020 and announced it would wind down operations.
Ross Doerr has mostly stopped using his Argus II, the result of combination of fear of losing its assistance from wear and tear and disdain for the company that brought it to market.

Second Sight’s implosion left some 350 Argus recipients in the metaphorical dark about what to do if their implants failed. Skeleton staff seem to have rarely responded to queries from their customers, at least based on the experiences of Perk and Doerr. And some recipients have unfortunately returned to the actual dark as well, as reports have surfaced of Argus II failures due to aging or worn-down parts.
Product support for complex products is remarkably uneven. Although the iconic Ford Mustang ceased production in the late 1960s, its parts market is so robust that it’s theoretically possible to assemble a new vehicle from recently crafted components. Conversely, smartphone and computer manufacturers typically stop issuing software upgrades to their devices after two or three years, eventually rendering them bricks. Consumers have accepted both extremes.
But is the smartphone approach acceptable for a device that helps restore the most crucial sense a human being possesses?
Margaret McLean, a senior fellow at the Markkula Center for Applied Ethics at Santa Clara University in California, notes companies like Second Sight have a greater obligation for product support than other consumer product ventures.
“In this particular case, you have a great deal of risk that is involved in using this device, the implant, and the after care of this device,” she says. “You cannot, like with your car, decide that ‘I don’t like my Mustang anymore,’ and go out and buy a Corvette.”
And, whether the Argus II implant works or not, its physical presence can impact critical medical decisions. Doerr’s doctor wanted him to undergo an MRI to assist in diagnosing attacks of vertigo. But the physician was concerned his implant might interfere. With the latest available manufacturer advisories on his implant nearly a decade old, the procedure was held up. Doerr spent months importuning Second Sight through phone calls, emails and Facebook postings to learn if his implant was contraindicated with MRIs, which he never received. Although the cause of his vertigo was found without an MRI, Doerr was hardly assured.
“Put that into context for a minute. I get into a serious car accident. I end up in the emergency room, and I have a tag saying I have an implanted medical device,” he says. “You can’t do an MRI until you get the proper information from the company. Who’s going to answer the phone?”
Second Sight’s management did answer the call to revamp its business. It netted nearly $78 million through a private stock placement and an initial public offering last year. At the end of 2021, Second Sight had nearly $70 million in cash on hand, according to a recent filing with the Securities and Exchange Commission.
And while the Argus II is still touted at length on Second Sight’s home page, it appears little of its corporate coffers are earmarked toward its support. These days, the company is focused on obtaining federal approvals for Orion, a new implant that would go directly into the recipient’s brain and could be used to remedy blindness from a variety of causes. It obtained a $6.4 million grant from the National Institutes of Health in May 2021 to help develop Orion.
Presented with a list of written questions by email, Second Sight’s spokesperson, Dave Gentry of the investor relations firm Red Chip Companies, copied a subordinate with an abrupt message to “please handle.” That was the only response from a company representative. A call to Second Sight acting chief executive officer Scott Dunbar went unreturned.
Whether or not the Orion succeeds remains to be seen. The company’s SEC filings suggest a viable and FDA-approved device is years away, and that operational losses are expected for the “foreseeable future.” Second Sight reported zero revenue in 2020 or 2021.
Moreover, the experiences of the Argus II recipients could color the reception of future Second Sight products. Doerr notes that his insurer paid nearly $500,000 to implant his device and for training on how to use it.
“What’s the insurance industry going to say the next time this crops up?” Doerr asks, noting that the company’s reputation is “completely shot” with the recipients of its implants.
Perk, who made speeches to praise the Argus II and is still featured in a video on the Second Sight website, says he also no longer supports the company.
Jeroen Perk, an investigator for the Dutch customs service, cried for joy after partially regaining his sight, but he no longer trusts Second Sight, the company that provided his implant.
Nanda Perk
Nevertheless, Perk remains highly reliant on the technology. When he dropped an external component of his device in late 2020 and it broke, Perk briefly debated whether to remain blind or find a way to get his Argus II working again. Three months later, he was able to revive it by crowdsourcing parts, primarily from surgeons with spare components or other Argus II recipients who no longer use their devices. Perk now has several spare parts in reserve in case of future breakdowns.
Despite the frantic efforts to retain what little sight he has, Perk has no regrets about having the device implanted. And while he no longer trusts Second Sight, he is looking forward to possibly obtaining more advanced implants from companies in the Netherlands and Australia working on their own products.
Doerr suggests that biotech firms whose implants are distributed globally be bound to some sort of international treaty requiring them to service their products in perpetuity. Such treaties are still applied to the salvage rights for ships that sunk centuries ago, he notes.
“I think that in a global tech economy, that would be a good thing,” says McLean, the fellow at Santa Clara, “but I am not optimistic about it in the near term. Business incentives push toward return on share to stockholders, not to patients and other stakeholders. We likely need to rely on some combination of corporately responsibility…and [international] government regulation. It’s tough—the Paris Climate Accord implementation at a slow walk comes to mind.”
Unlike Perk, Doerr has mostly stopped using his Argus II, the result of combination of fear of losing its assistance from wear and tear and disdain for the company that brought it to market. At 70, Doerr says he does not have the time or energy to hold the company more accountable. And with Second Sight having gone through a considerable corporate reorganization, Doerr believes a lawsuit to compel it to better serve its Argus recipients would be nothing but an extremely costly longshot.
“It’s corporate America at its best,” he observes.
