Scientists have estimated that bowhead whales — the longest-living whale species — can live more than 200 years.
It was once thought that the bowhead’s cousin, the right whale, had an average lifespan of about 70 to 80 years, but new research has revised that estimate to more than 130 years — nearly twice as long!
“From the standpoint of physiological scaling, these superannuated ages should not be unexpected. Whales are the largest living animals, and body size is highly correlated with longevity,” the authors of the study wrote.
The researchers worked with Indigenous subsistence hunters from Utqiaġvik, Alaska. They used chemical analysis of bowhead whales that had been killed to demonstrate that they are able to live more than two centuries, a press release from University of Alaska Fairbanks said.
The chemical evidence was corroborated by harpoon tips from the 19th century being recovered from bowheads killed during modern hunts.
Right whales are more closely related to bowheads than any other species and appear to have similar lifespans. Like their cousins, right whales filter their food through baleen plates and make seasonal migrations to birthing grounds.
The names given to right whales were sadly from whalers considering them to be the “right” whales for hunting because their thick blubber caused them to float after they had been killed.
“Industrial whaling, which for most species ended only 60 years ago, would have required any individuals now aged over 100 years to have survived at least 40 years of intense whaling, and any individual over 150 would have had to survive 90 years of that same intense hunt,” the authors wrote in the study. “Given that many whale species were reduced to less than 10% of their original population size, and the population minima for most species were reached in the mid-20th century, that degree of whaling would have rendered superannuated individuals extremely rare or completely absent from the age structures of most populations. Consequently, extremely old whales may not be part of the demographic makeup of current whale populations, even if they historically existed.”
The researchers looked at four decades of data that had been collected through photo identification programs tracking critically endangered North Atlantic right whales — who live along North America’s Atlantic coast — and Southern right whales, found south of the equator, the press release said.
The research team constructed survivorship curves — graphs showing how many of a population survives to each age — using the data, which are similar to those insurance companies use in the calculation of human life expectancies.
Their analysis showed that Southern right whales can live longer than 130 years — with some possibly living to 150 years — rather than the 70 to 80 years that had been previously thought.
In contrast, the team found that the average North Atlantic right whale lifespan is only 22 years, with few individuals living past 50.
Associate professor Greg Breed with University of Alaska Fairbanks explained that the stark contrast between the lifespans of bowhead and right whales is mostly due to human impacts.
“North Atlantic whales have unusually short lifespans compared to other whales, but this isn’t because of intrinsic differences in biology, and they should live much longer,” Breed, who is lead author of the study, said in the press release. “They’re frequently tangled in fishing gear or struck by ships, and they suffer from starvation, potentially linked to environmental changes we don’t fully understand.”

Breed has been studying marine mammals for years, including seals. Certain seal species have lifespans of up to 50 years. Narwhals can live a century or more.
Breed noted that there have been significant underestimations of whale lifespans in the past due to lack of whale aging data.
“We didn’t know how to age baleen whales until 1955, which was the very end of industrial whaling,” Breed explained. “By the time we figured it out, there weren’t many old whales left to study. So we just assumed they didn’t live that long.”
The new research could provide valuable information for future conservation efforts.
“To attain healthy populations that include old animals, recovery might take hundreds of years,” Breed said. “For animals that live to be 100 or 150 and only give birth to a surviving calf every 10 years or so, slow recovery is to be expected.”
The study highlights the essential nature of cultural knowledge in whale communities.
“There’s a growing recognition that recovery isn’t just about biomass or the number of individuals. It’s about the knowledge these animals pass along to the next generation,” Breed said. “That knowledge isn’t just genetic — it’s cultural and behavioral. Older individuals teach survival skills. Younger animals learn by observing and copying the strategies of the older ones.”
Breed and his colleagues plan to expand their research to additional whale populations and explore the possibility of other whale species currently believed to have lifespans of roughly 80 years living much longer. The researchers hope to discover more about whaling’s impact on the number of long-lived individuals in current populations and predict when they will recover to pre-whaling population numbers.
The study, “Extreme longevity may be the rule not the exception in Balaenid whales,” was published in the journal Science Advances.

As a longtime book lover, I may be biased, but I think a full bookshelf is one of the most beautiful additions to a space. There’s nothing better than seeing a showcase of your favorite reads alongside a TBR list.
A bookcase, though, can of course be used for all sorts of purposes from placing your favorite photos of family and friends to showcasing treasured vintage finds.
Whatever the case, this guide will help you find the right sustainable bookshelf for your living room, office, or wherever you like to cozy up with a good read!
So what make a bookcase more sustainable? What makes a bookshelf non-toxic?
First of all: sustainable and non-toxic are two overlapping — but distinct — criteria. And both of those terms can come with a lot of opinions and varying definitions.
When it comes to sustainable bookcases, I look for:
- Responsibly Sourced Materials: most bookshelves are made primarily with wood. While natural, unsustainable wood sourcing can be a cause of deforestation, so we want to see that the wood was from responsibly managed forests or made from reclaimed or repurposed wood. Some bookshelves may feature metal, in which case recycled materials here are important.
- High Quality Construction: sustainability includes longevity — how long will you be able to use that furniture piece before it goes to the landfill and gets replaced? Look for transparency around craftsmanship and woodworking processes. Another sign of quality is the length of warranty a company has for its products.
- Ethically Made: this one is straightforward in theory — were the people making it paid fairly and working in safe conditions? — but is unfortunately not always easy to find information. In this category, I look for transparency in practices, what relationship the brand has with the manufacturer (some produce in-house which is the best case scenario for transparency!), where it was made, and how well the makers were paid.
Ideally a sustainable bookshelf would also be non-toxic — as toxic chemical fumes aren’t exactly sustainable! But this isn’t always the case. For example, if a company prioritizes upcycled materials, they don’t necessarily have control over what inputs were part of the original materials. And sometimes a company focuses more on ethical artisan partnerships and sustainable wood sourcing, more than, say, using non-toxic finishes.
But when it comes to non-toxic bookshelves, this is what I look for. (Note that non-toxic doesn’t necessarily mean safe for all chemical sensitivities. Nor does it mean zero potentially irritating chemicals.)
- Solid Wood (where possible): MDF or pressed wood contains glue to stick the various wood pieces together, which can contain added formaldehyde. I prefer solid wood, or if it is engineered wood, I’d make sure the company is transparent around the type of glue used and/or they at least have a product certification like GREENGUARD. (More on that in a second.)
- Low or Zero VOC Finishes: most wood furniture is completed with some sort of finish to provide a protection against scratches or moisture. Many of these finishes are synthetic, and some can contain high levels of toxic chemicals. Look for a natural finish like linseed oil or beeswax or a low VOC synthetic finish.
Relevant Certifications
You’ll see a few certifications referenced throughout this guide. Here’s what each one covers:
- FSC Certified = the wood sourcing was responsibly managed; this is not a finish, foam, or textile guarantee.
- GREENGUARD / GREENGUARD Gold Certified = the finished product was tested for low chemical emissions, including VOCs, with Gold representing the stricter tier.
- Fair Trade Certified
= verifies that a factory meets standards for fair wages, safe working conditions, and ethical labor practices. - Cradle to Cradle Certified (Gold) = evaluates a product or material across material health, circularity, clean air/climate, water/soil stewardship, and social fairness.
Where to Find Sustainable Bookcases and Shelving
I’m always a secondhand first proponent, and that goes for furniture, too. While your local thrift store might not have used bookshelves, check for dedicated furniture resale shops near you or estate sales. (I use EstateSales.net to find ones near me.) You can also find gently used pieces on online marketplaces like Facebook Marketplace, OfferUp or AptDeco.
If you can’t find something you love secondhand, and you don’t want to DIY your own bookshelf, then the next best choice is to shop from one of the sustainable furniture companies below. (If you’re simply looking for a bookstand, I’d suggest browsing Etsy for a collection of solid wood, bamboo, and reclaimed wood book stands and cookbook stands!)

Put your feet up and relax with the eco-friendly and non-toxic ottomans, benches, and poufs from these incredible sustainable furniture brands.
What makes an ottoman, pouf, or bench sustainable?
There are a lot of considerations that go into making sustainable furniture. Some brands may meet more of these criteria than others, and some criteria may be more or less important to you.
You might also engage with sustainability differently depending on your lifestyle, budget, aesthetic preferences, among other factors. But here’s a general idea of what to look for:
Look Secondhand
Used ottomans and benches are going to the most sustainable option since these furniture pieces have already been produced! Plus you’re preventing that furniture from heading to a landfill. You could browse an app like OfferUp or check your local Facebook Marketplace.
You can also check secondhand furniture sites like AptDeco and Chairish
Shopping for new sustainably-made ottomans and benches? Check out the following tips:
Eco-Conscious & Durable Materials
With the rise of fast furniture, the quality (and the sustainability) of materials used in furniture has declined. I’m consistently blown away by the incredible condition of so much vintage mid-century modern (1930s-1970s) furniture out there!
A sustainable ottoman (or sustainable bench) would be made durably so it lasts and would be constructed from responsibly sourced materials such as FSC-Certified and/or locally sustainably-harvested wood, recycled fabrics and organic natural fabrics for the upholstery, and non-toxic — ideally zero VOC — finishes. This guide has more non-toxic furniture brands.
Responsibly Made
Look into where the brand is producing their ottomans, benches, and/or poufs. Is it in their own workshop or a nearby production facility? Is it in a fair trade artisan workshop? A brand should have full transparency and traceability of their supply chain.
They also should ensure workers are earning living wages and work in safe environments. (This is where the overlap with non-toxic comes in — when there are toxic chemicals used in furniture, supply chain workers are exposed to these toxins in far greater quantities than consumers.)
Circular Practices
The EPA estimates that 12 million tons of furniture are thrown out annually. Yikes. A brand selling sustainable benches and ottomans would ideally consider the following:
- Quality construction so the furniture lasts a lifetime (or several)! If you’re moving a lot, it’s also worth considering how easy that piece of furniture is to move around and deconstruct/reconstruct if necessary. Though this probably is less of a concern with a smaller piece of furniture like a pouf, bench, or ottoman.
- Repairability. Is that material repairable? Does that brand have replacement parts? Is it a material that could be refinished or reupholstered easily? For example “vegan leather” (typically plastic) is very difficult to keep up or repair.
- Secondhand program or resellability. It would be incredible if the brand had a resale program for their furniture. Not many brands do, though. So you might also just think about if the style and quality of the piece would make it easy to sell again if you do think you might outgrow it.
