More than a third of animals on Earth are herbivores, but since plants don’t have a lot of calories it can be hard for grazers to eat enough to meet their energy needs. To add to the problem, climate change is lowering the nutritional value of certain foods that these plant eaters rely on.

Fossil fuel emissions produced by humans are causing levels of atmospheric carbon dioxide to rise, pushing up temperatures worldwide. This is causing plants to grow faster in ecosystems across the globe, research biologist Ellen Welti with the Smithsonian Institution’s Great Plains Science Program wrote in The Conversation.

“Some studies suggest that this ‘greening of the Earth’ could partially offset rising greenhouse gas emissions by storing more carbon in plants. However, there’s a trade-off: These fast-tracked plants can contain fewer nutrients per bite,” Welti wrote in The Conversation.

Welti and colleagues looked at the ways in which nutrient dilution might impact species throughout the food web. They focused on the responses of plant-feeding populations, from giant pandas to grasshoppers.

“When we look at future climate change, it’s not the same as the current hot years that we experience,” said Alex Ruane, co-director of NASA’s Goddard Institute for Space Studies’ Climate Impacts Group. “If we were to find a location and look at a hot year that was recently experienced, it would likely have been a heat wave that would have raised the overall temperature. Climate change is different. Climate change is every day, a little bit more and more. When those heat waves come [in the future], they’re just a little bit more intense or extreme, and that has a different physiological impact [on plants].”

Welti said changes in plants’ long-term nutritional value could be one underappreciated cause of falling animal populations.

“These changes in plants aren’t visually evident, like rising seas. Nor are they sudden and imminent, like hurricanes or heat waves. But they can have important impacts over time,” Welti said in The Conversation. “Plant-eating animals may need more time to find and consume food if their usual meal becomes less nutritious, exposing themselves to greater risks from predators and other stresses in the process. Reduced nutritional values can also make animals less fit, reducing their ability to grow, reproduce and survive.”

The nutrient value of livestock feed has also been declining. It is often difficult for cattle — who spend much of their time eating — to find enough protein, as protein concentrations are falling across rangelands all over the planet, threatening livestock and ranchers.

Nutrition dilution also affects wild species like some insects.

“Insects are essential members of the web of life that pollinate many flowering plants, serve as a food source for birds and animals, and perform other important ecological services. Around the world, many insect species are declining in developed areas, where their habitat has been converted to farms or cities, as well as in natural areas,” Welti explained. “Many insects are plant feeders that are likely to be affected by reduced plant nutritional value. Experiments have found that when carbon dioxide levels increase, insect populations decline, at least partly due to lower-quality food supplies.”

Leaf-chewing insect species like caterpillars and grasshoppers suffer the most negative impacts, from smaller body sizes to reduced reproduction.

Other insects like cicadas and aphids could benefit from carbon-rich plants.

“Certain types of plant-feeding animals are likely to face greater declines because they need higher-quality food. Rodents, rabbits, koalas, horses, rhinoceroses and elephants are all hind-gut fermenters – animals that have simple, single-chambered stomachs and rely on microbes in their intestines to extract nutrients from high-fiber food,” Welti added.

Welti said more research will be necessary to understand the role of nutrient dilution in the declines of individual species.

“Over the longer term, it will be important to understand how nutrient dilution is altering entire food webs, including shifts in plant species and traits, effects on other animal groups such as predators, and changes in species interactions. Changes in plant nutritional value as a result of rising carbon dioxide levels could have far-reaching impacts throughout ecosystems worldwide,” Welti said.

8 Best Ethical & Sustainable Flats That Are Effortlessly Chic

Published

on

Ballet flats have long been a staple in my wardrobe, but in the past few years have experienced a significant resurgence — and for good reason. The right pair can be practical, versatile, and oh so chic through days at work, with family, or out for the evening. But finding that “just right” set that’s well-crafted and sustainably made can be a whole other story. That’s why this sustainable flats guide exists.

Comfort, style, sustainability, and longevity are a lot to ask in a shoe, but I don’t believe it’s too much. It just takes some extra digging. And thankfully, I’ve done that digging for you. Because I get it! I want a flat that looks beautiful. I want a flat that’s made responsibly in line with my values. I want a shoe I can actually wear for my life. And I want that shoe to be worth the investment — it has to last. That’s why I vetted through dozens of brands to create this curated list of flats.

What Makes a Flat More Sustainable?

Material Sourcing

Footwear is a tricky category when it comes to sustainable fashion because we ask a lot of our shoes. We wear them in rain or sunshine, paved paths and cobblestone, day in and day out for years. And through it all, they have to remain beautiful. Because when they’re unwearable, there’s not much left to do with them: there is no viable footwear recycling today. Anywhere that calls it “shoe recycling” is really repurposing that footwear. But once it can no longer be worn, it’s simply trash.

In other words, our shoes need to be incredibly durable, even though the most durable materials don’t always come with the lightest footprint. In footwear, when we talk about durability, we usually rely on leather or high-performance synthetic materials. Leather can hold up with many years of wear, getting more beautiful with wear, and is easy to repair when needed. Synthetic materials are also durable, particularly for withstanding the elements like snow and rain.

But sourcing these materials conventionally is highly polluting — so how can we source these materials better?

For synthetics, we have recycled options. Today, that’s largely recycling from plastic bottles, which isn’t without it’s controversies, but there is much innovation happening in the industry around true textile-to-textile recycling.

For leather, I look for:

  • Vegetable-tanned (rather than chromium tanned)
  • Locally-sourced leather (more traceability), and/or
  • Leather Working Group certified leather, which covers responsible management of water, energy, and waste; safe chemical management, traceability of the raw material, and occupational safety for workers.

Notably, there is no certification for animal welfare, so these are imperfect systems. But the alternative is footwear made from synthetic plastic materials or vegan leather alternatives that don’t yet meet the same durability standards as leather. Sustainability within today’s constraints requires trade-offs.

That said, there is always secondhand leather — by buying shoes secondhand you can access the quality of leather without adding further demand for the material.

Responsible Manufacturing

When considering responsible production practices, I look for first and foremost: transparency. Seeing what the brand shares about their material sourcing, their process, and who made their shoes where. And then I look at the details of that process: were the shoes made locally or within a geographic region? How are the workers paid and treated — and under which conditions do they work?

And, sometimes a brand employs an out-of-the-box approach to manufacturing entirely. There are a few slow fashion footwear brands challenging the traditional fashion system of ordering in mass quantities before demand is assessed —which inevitably leads to overproduction. These brands use an “on demand” model instead, producing their shoes only after they’ve been ordered. This reduces the risk of overproduction (i.e. producing more than what gets sold) while also encouraging more thoughtful consumption. You can’t impulse buy a pair of Mary Janes that you have to wait 8 weeks for.

Wearable and Beautiful

The most perfectly environmentally sustainable flat in the world is useless if no one wants to wear it. And as I mentioned earlier, footwear cannot be recycled into new footwear at the end of its life, so we want our shoes to last a really long time. That means they need to be design forward and comfortable, too.

My Top Picks for More Sustainable and Ethical Flats

Keeping all of that in mind, these more sustainable flats brands meet this criteria, albeit to various extents. Some err more on comfort while some more on style. Some have admirable levels of transparency and social impact, while other brands have more of a focus on their ecological impact. I’ve included descriptions alongside each brand as well as a summary of conscious qualities so you can find a brand that meets your priorities best. And, of course, a price range so you know what makes sense for your budget as well.

Some that this guide includes affiliate links which means we may earn a commission if you shop through these links. As always, brands featured in shopping guides are brands that meet our strict sustainability criteria that we think you’ll love.

1. ALOHAS

Spanish brand ALOHAS flips the typical fashion production system on its head with its on-demand model.

Instead of overproducing thousands of shoes to later discount them, ALOHAS does the exact opposite. Its newest styles are available for pre-order at a discount of 30%, so the footwear brand can more accurately forecast demand. Then the shoes — like their flats — are primarily made by local artisans in Spain and Portugal. The brand regularly shows the behind the scenes of their production on their social media.

Conscious Qualities: On-Demand Production, Locally Made

Size Range: EU 35-42 (US 5-11)
Price Range: $195-$225

2. Rothy’s

If you’re looking for flats for all-day wear at work or running errands, Rothy’s is my recommendation with their cushy insoles. The brand makes their more sustainable flats from recycled plastic bottles, as well as materials like hemp and merino wool, but they still look sleek enough for the office.

While I might not wear Rothy’s flats to a fashion event (I prefer smooth leather for more elevated occasions), they are more than stylish enough to wear to most of my real-life scenarios. My favorite part about Rothy’s, though, is that they are machine washable.

Materials: Recycled & Natural Materials, Owns One Factory (undisclosed percentage of production)

Size Range: US 5-13
Price Range: $99-$165

3. Vivaia

Vivaia has the most adorable sustainable Mary Janes made from recycled plastic bottles. The adjustable straps and arch support make Vivaia’s Mary Janes suitable for all-day comfort, even if your feet are typically prone to slipping out of flats.

This vegan footwear brand also makes square-toe and pointed-toe flats for a more elevated look. And of the several recycled plastic bottle footwear brands on the market today, Vivaia tends to have the most elevated designs in my opinion.

Conscious Qualities: Vegan, Recycled Materials

Size Range: US 5-11
Price: $97 – $116

4. The RealReal

The RealReal is an authenticated luxury resale platform with contemporary, designer, and high-end luxury brands. Depending on your priorities you can find shoes in anywhere from pristine condition (but higher priced)) to “fair” or even “as is” for the largest discount from full price.

You don’t always have as many options aesthetically when shopping more sustainably, so I like to go to The RealReal when I’m looking for specific styles. I was recently looking for Mary Janes with feminine detailing and came across Larroude Flats on The RealReal, where I purchased a pair of neutral scalloped accent flats. (Pictured here!)

Conscious Qualities: Secondhand

Size Range: US 3.5-14
Price Range: $9+

5. ESSĒN

ESSĒN elegant, minimalist footwear is artisan handcrafted from Leather Working Group-certified leather in solar-powered facilities in Italy, Portugal, and Spain. Each shoe also comes with a product passport where you can view the step-by-step journey that product took through the brand’s supply chain from raw material to manufacturing to packaging and distribution.

Beyond transparency and responsible manufacturing, ESSĒN’s slow fashion business model prevents overproduction by operating on a made to order basis. Meaning while sizes and styles are predefined, the shoes are only produced after they’ve been ordered.

Conscious Qualities: LWG Certified, Supply Chain Transparency, On Demand Production

Size Range: EU 35-44 (US 4-13)
Price Range: $295-$450

Chocolate brown leather classic flats

6. Allbirds

Another comfort-first footwear option besides Rothy’s is Allbirds. The brand creates lightweight, super smooth and breathable flats from tree fibers, aptly called “Tree Breezers”. The (washable) shoes are also soft enough to wear without socks.

The Allbirds Tree Breezers are far more comfortable than typical flats, though I find that the Rothy’s are slightly comfier.

Conscious Qualities: Natural materials (FSC-Certified eucalyptus, castor mean oil, sugarcane EVA)

Size Range: US 5-11
Price Range: $105-$125

Gray wool flats

7. Darzah

Fair trade certified by Fair Trade Federation, Darzah’s ethical flats are entirely hand-embroidered and handcrafted in Palestine from locally sourced leather.

The tatreez flats from this nonprofit are embroidered by refugee and low-income women artisans in the West Bank with this traditional Palestinian techniques.

Conscious Qualities: Sustains Heritage Crafts, Fair Trade Certified

Size Range: EU 36-41 (US 6-10)
Price Range: $199 – $209

Tatreez fair trade flats in red and blue

8. Nisolo

If you’re seeking a quality pair of classic leather flats ideal for your capsule wardrobe, Nisolo is a strong pick. Nisolo’s flats are handcrafted by artisans using leather sourced from a Leather Working Group certified tannery.

I’ve been wearing my Nisolo shoes for many years and can attest to their quality and durability.

That said, the brand has recently turned over to new ownership and now has significantly less information about their sustainability and ethics in their supply chain. I will be keeping a close eye on this brand to see if it continues to uphold the values Nisolo has long held.

Conscious Qualities: LWG-Certified, Artisan Handcrafted

Size Range: US 5-11
Price: $138 – $198
