I do my best to cultivate a minimalist and sustainable wardrobe I can wear for a long time. Two ways I do this is by creating a capsule wardrobe and being mindful of the fabrics I choose to wear.
I try to opt for natural fibers whenever I can. Synthetic materials shed microplastics over time, aren’t as durable, and can’t be composted at the end of their life. Plus, I don’t really like how synthetic materials feel on my skin.

Synthetic and semi-synthetic materials are also often treated with harsh chemicals during the manufacturing process.
One such material is cupro fabric. Have seen it before on your clothing tag? It’s not the most common fabric, but what exactly is cupro and is it eco-friendly?
Cupro is a vegan alternative to silk. It’s a semi-synthetic fabric made from recycled cotton. But that doesn’t automatically make it sustainable. A lot of harsh chemicals are used in the formation of cupro.
In fact, cupro is illegal to produce in the United States. This means most of Cupro is imported from other countries. There are specific reasons for this we will dive into below.
If you’re considering buying an item made from cupro, here’s everything you need to know about the fabric, and if it’s sustainable.

is cupro natural or synthetic?
Cupro is a semi-synthetic fabric that is made primarily from cotton waste from the cotton growing industry. Though cupro is derived from a natural source, it’s mixing with various chemicals during the manufacturing process make it hardly pass as a natural fiber.
The raw material of cupro is natural though: It’s called cotton linter which is a material obtained from the manufacturing process of cottonseed oil. Cotton linter is the short downy fiber enfolding cotton seeds.
While cotton linter itself is biodegradable and compostable, I wouldn’t recommend composting cupro fabric due to the harsh chemicals used in the manufacturing process. Composting it would release any toxins from production, dyeing, and washing into the ground which is not recommended.
Cupro is classified as biodegradable (which simply means it will break up over time). Technically, so will plastic, but that doesn’t make it sustainable.
RELATED: Biodegradable vs Compostable: What’s the Difference?
Cupro is short for cuprammonium rayon. It got its name because the solution of copper and ammonia is used to make this particular type of rayon. Rayon was created as an alternative to silk and rose in popularity because of its lower price point.
Rayon made using the cuprammonium process can be labeled cupra, cupro, or cupra rayon under the trade name Bemberg.
how is cupro made?
1. First, they expose the cellulose of a plant product to a mixture of ammonium and copper.
2. Then these two elements are combined with the cellulose to make a new substance.
3. The mixture is then dropped into caustic soda and extruded through a spinneret.
4. The extruded strings are immersed into a series of hardening baths that reconstruct the cellulose and remove the ammonia, copper, and caustic soda.

is cupro a good fabric?
Cupro is a good fabric in terms of working as a vegan and cruelty-free substitute for silk. It’s also generally less expensive than silk, with similar look and feel.
It’s smooth, light, texture works well for clothing that drapes across the body, like dresses and blouses.
However, in terms of the environment, cupro isn’t the most sustainable material out there – and we’ll discuss why.
environmental impacts of cupro fabric production
Cupro is considered a recycled material. This is because it’s made from a byproduct of the cotton industry, cotton linters.
However, cotton is a crop that is known for using massive amounts of water and pesticides which can pollute ecosystems and waterways. Conventional cotton has been known to cause soil degradation.
Even if cupro was sourced from organic cotton, which it often is not, it still uses a lot of hazardous chemicals during the manufacturing process, such as copper sulfate, ammonia and caustic soda.
According to the Council of Fashion Designers of America (CFDA), cupro is illegal to produce in the U.S. due to the manufacturers inability to comply with water and air protection regulations.
Also, chemicals used to make cupro can harm workers. According to CFDA, work accidents can occur from explosions or leaks in chemical storage areas associated with any form of rayon production.
Cupro can now be made in a closed-loop system, but the only manufacturer to do this is Asahi Kasei in Japan under the trademark Bemberg. Their system ensures that the copper and ammonia used in manufacturing is recovered and reused.
While this is an improvement, it’s worth noting that most of cupro is still made and exported from China, where there is less transparency regarding the production process. There, the fabric is often referred to as ammonia silk.
Also, it’s worth noting that any form of rayon production (cupro, viscose, etc.) involves copious amounts of water waste, on top of being an energy intensive process.
Most factories that manufacture rayon (and cupro) are usually powered by fossil fuels, which release emissions that contribute to climate change. This is not limited to just rayon though, as many factories that generate synthetic materials are often powered by fossil fuels.

sustainable alternatives to cupro
If you’re looking for a more sustainable alternative to cupro, I recommend looking into TENCEL Lyocell and Modal from Lenzing AG. These are both imperfect alternatives, also both sourced from rayon, but they are more transparent with their production processes.
They are both vegan and cruelty-free and possess similar qualities to cupro.
When choosing a rayon-based material, it’s important to look for sustainably forested, low-chemical, closed-loop producers with certifications like FSC, EU Ecolabel, and OekoTex 100.
Here’s a bit more about both TENCEL Lyocell and Modal fabrics from Lenzing.
tencel lyocell
- Their fibers are produced in a closed loop process which recovers water and 99.8% of the solvent, which transforms wood pulp into cellulosic fibers with high resource efficiency and low environmental impact.
- Biodegradable and compostable, if it is not combined with any polyester, elastane or nylon fabrics/elements.
tencel modal
- A bio-based, semi-synthetic fabric made from spinning beech tree cellulose.
- Carbon-neutral, has a smaller water footprint, and requires less land per tonne than cotton fibers.
- Completely biodegradable and compostable under industrial, home, soil and marine conditions.
Be aware that Lyocell and Modal made outside of Lenzing AG may not be as eco-conscious, because they don’t have to meet their rigorous standards. Modal and lyocell you see without the TENCEL
certification is likely made in factories that aren’t being transparent about their practices both socially and environmentally.
Try to always buy from brands that have the TENCEL
modal and lyocell certification, if you can.

7 DIY Recycled Bird Feeders
Before you throw away that empty soda bottle, wine bottle, or milk carton, think about turning it into a bird feeder.
These seven DIY projects show how to reuse common household items to make useful backyard wildlife stations. There’s something for everyone, whether you’re crafting with kids or have experience with tools. Whenever possible, choose glass instead of plastic. Experts say glass bottles last longer in the sun and are easier to clean than plastic.
This article contains affiliate links that help fund our work.
1. Soda Bottle Bird Feeder

The soda bottle bird feeder is a classic project that’s easy for anyone to make. Start by saving a 1- or 2-liter soda bottle from the recycling bin. Then, find two wooden spoons, dowels, or sturdy twigs from around your home or yard. These will serve as perches for the birds.
To make one, follow the instructions from Gardening Know How: mark two sets of holes at right angles, insert the spoons or dowels, fill the bottle with birdseed, put the cap back on, and hang it up with string or fishing line. If you’re working with young kids, adults should handle the cutting.
If you prefer not to do DIY from scratch, you can buy soda bottle bird feeder kits. Just attach the tray and wire to your own bottle.
2. Milk Carton Bird Feeder
Making a bird feeder from a milk or juice carton is just as easy as using a soda bottle. The Audubon Society even has a version that’s great for kids. Cut a large opening a few inches from the bottom on one side, add a stick underneath for a perch, make two small holes at the top for hanging, decorate it, and fill with birdseed.
Keep in mind that milk cartons don’t last as long as plastic or glass feeders. Watch for signs of wear and replace your feeder when needed. Remember to recycle the old carton.
3. Tray Bird Feeder

If you have leftover wood from a home project, you can make a simple tray feeder using Birds & Blooms’ instructions. You’ll need cedar or pine scraps, an aluminum screen for drainage, panel nails, eye screws, and some chain for hanging. You should also be comfortable using a drill and hammer.
You can also reuse old windows, picture frames, or other wooden items from around the house to make a tray feeder. One Instructables tutorial shows how someone built a feeder from the wooden backing of an old bronze award.
Tray feeders bring in many types of birds, like cardinals, chickadees, woodpeckers, and mourning doves. However, they don’t keep out squirrels.
4. Floppy Disk Bird Feeder
If you have some old floppy disks lying around, you can turn them into a retro bird feeder using an Instructables guide.
You’ll need to take apart three disks, remove the magnetic film, cut a window for the seeds, put the pieces together to form a cube, and attach a string for hanging. Use tape or a hot glue gun to hold it together, then add birdseed inside.
5. Self-Refilling Glass Bottle Bird Feeder
This gravity-fed feeder is a smart upgrade from basic designs. Remodelaholic’s wine bottle bird feeder tutorial explains how to build a simple wooden platform with a notched holder that keeps an upside-down glass bottle just above the seed tray. As birds eat, gravity refills the tray with more seed.
You need only a recycled wine bottle (or any narrow-neck glass bottle) and some wood for this project. The screw-based mount makes it easy to remove the bottle for refilling. Use a low- or no-VOC wood sealer to protect the frame.
6. Plastic Bottle Hummingbird Feeder
Want to bring hummingbirds to your yard? Try this Instructables guide for making a hummingbird feeder from recycled plastic containers. It uses a pop bottle and a deli container lid, like the ones from grocery store takeout, with milk bottle caps glued on as feeding ports.
Fill the bottle with hummingbird nectar. The International Hummingbird Society suggests mixing one part white sugar with four parts water. Don’t use food coloring, honey, or artificial sweeteners. The red parts of the feeder attract the birds, not the nectar itself.
If you want something sturdier and easier to clean, Birds & Blooms offers instructions for a glass bottle hummingbird feeder that uses copper wire and a commercial feeding tube. This version takes more effort to make but lasts much longer.
7. Glass Soda Bottle Bird Feeder

This is a step up in craft and durability, and a good reason to save that glass Jarritos or Mexican Coke bottle. Birds & Blooms’ glass soda bottle feeder tutorial pairs a recycled glass bottle with a chicken feeder base for a sturdy feeder that holds plenty of seed and will last for years.
The most involved step is drilling a hole in the bottle’s bottom using a diamond drill bit under running water to keep the bit cool so the glass doesn’t crack. A steel rod threads through the bottle and into the chicken feeder base, locked in place with a washer and wing nut; a G-hook at the top completes the hanger. To refill, simply unscrew the base, add seed, and reattach.
This DIY project requires comfort with a drill and patience with glass, but the result looks intentional and well-made, not like a weekend craft project. For the nectar-recipe and feeder-cleaning guidance that applies to all glass bottle builds, the International Hummingbird Society’s feeding page and Birds & Blooms’ black oil sunflower seed guide are solid references depending on what you’re trying to attract.
To find out where to recycle glass bottles in your area, check the Earth911 Recycling Directory. Most curbside programs don’t accept them, but many drop-off sites do.
Tips for Bird Feeders
- Clean your feeders every one or two weeks to stop mold and bacteria from harming birds.
- Hang feeders at least five feet above the ground and away from bushes where cats might hide.
- Black oil sunflower seeds attract the most types of birds.
- For hummingbird feeders, change the nectar every two or three days. In hot weather, change it even more often.
- Plastic feeders break down faster than glass ones in sunlight. Check them regularly and replace when needed.

Sustainability In Your Ear: Schneider Electric’s Steve Wilhite Maps the Renewable Energy Transition
The global energy system is changing in two big ways: it is moving from centralized fossil-fuel generation to distributed renewables, and it is becoming more digital in how energy is measured, traded, and optimized. Steve Wilhite, Executive Vice President of Advisory Services at Schneider Electric, works at the intersection of these complementary yet challenging transitions. Schneider supports more than 40% of the Fortune 500 with energy procurement and sustainability strategies, managing over $50 billion in annual energy spending. His experience shows something that pledges and press releases often miss: the biggest challenge for corporate sustainability is not money, technology, or political will. The real issue is the gap between ambition and the ability to deliver. Companies are making Science-Based Targets commitments faster than they are building the infrastructure to meet them. Scope one and two emissions are being managed better, but scope three emissions, which come from a company’s supply chain, still present a systems problem that no single company can solve alone. Schneider’s zero-carbon supplier program suggests what it takes to close this gap. When the company started its own effort to cut emissions from its top 1,000 suppliers by 50% in five years, all 1,000 signed up within two weeks. However, about 84% of them did not fully understand what they had agreed to. Achieving success meant creating measurement tools, education programs, and action plans to help the whole ecosystem, not just individual companies.

This critical conversation explores how renewable energy is bought, including the difference between physical and virtual power purchase agreements. Steve also explains why the Power Purchase Agreement (PPA) market became more complex as it grew, and why 10% fewer renewable deals closed in 2025 compared to 2024, as tech companies used up available clean energy. He also addresses a key question in clean energy: is AI helping the environment overall, or do its energy needs still outweigh its efficiency benefits? Schneider processes over a million energy invoices each month, and about 50,000 of them had issues that took 10 to 15 business days to resolve. Now, a team of AI systems can handle these in seconds. Accurate energy consumption and billing data directly affect emissions reporting, energy efficiency, and money-saving market decisions. He describes Schnieder’s approach as “frugal AI”: using the right-sized models for each task, running them on clean energy, and choosing simple solutions over complex ones. Looking ahead, electrification is building a global digital energy network in which every meter and adjustment contributes to a new system independent of central plants. As intelligence spreads, power can shift to consumers, communities, and businesses. Schneider is enabling this shift by building a mesh grid in which each point both produces and consumes energy, coordinated by AI. These changes fundamentally reshape the global energy landscape. The central question: will we intentionally build this new, distributed system, or will we repeat centralized patterns digitally?

The West Is Burning Before Summer Even Starts, and It’s No Accident
Nevada just shattered its March statewide high temperature record by 6 degrees, which is a ‘72 miles per hour in a school zone’ kind of margin. And it happened during the hottest 11-year stretch in 176 years of recorded temperature tracking.
A mid-March heat wave in the American West pushed temperatures in Laughlin, Nevada, to 106°F, far above the previous March record of 100°F. The fact that this happened in March is alarming, especially since it coincided with a near-total collapse of the region’s snowpack. This sets the stage for an early and possibly severe wildfire season. The heat also fits a troubling trend confirmed by the World Meteorological Organization last week: 2015 through 2025 have been the 11 warmest years ever recorded on Earth.
Usually, temperature records are broken by small amounts. What happened in Nevada last month was very different. Some places broke monthly high temperature records by as much as 8 degrees. Reno had seven days above 80°F in March, compared to the previous record of just two days. “It’s not just that we broke monthly records,” said Nevada State Climatologist Baker Perry, “but it’s by how much we broke the monthly records, and not just in one place.”
A Snow Drought That Wasn’t in the Forecast
The heat wave didn’t hit a typical winter landscape. Nevada was already experiencing what Perry calls an unprecedented snow drought. Even though winter precipitation was close to normal and there were big storms in mid-February, warm, moist air arrived soon after. This caused what the National Weather Service called the second-highest single-day snowmelt ever recorded in the eastern Sierra, only surpassed by flooding in 1997.
Normally, snow melts slowly through April and May, but this year it happened all at once in late February and early March. SNOTEL monitoring stations across Nevada show the impact clearly: 70% of sites in northern and central Nevada now report zero inches of snowpack. That’s not just low—it’s gone. The incidence of drought is closely correlated with rising atmospheric CO2 levels recorded at the Mauna Loa Observatory in Hawaii, which is threatened with defunding by the Trump Administration.

What worries scientists most is the combination of these events. “To have these two unprecedented, exceptional events happening at once is a combination that is particularly concerning,” Perry said.
What This Means for Fire Season
Wildfire risk isn’t only about heat. It depends on the sequence of conditions leading up to fire season, and this year’s setup is especially dangerous.
The snowmelt and early rains caused plants to grow weeks ahead of schedule. This early growth creates lots of fine fuels. As these plants dry out over the spring—now with less moisture from snowpack—they become the kindling that can fuel fast-moving fires.
Truckee Meadows Fire Protection District Division Chief August Isernhagen said the early green-up could lead to conditions we haven’t seen before as fire season approaches. He urged people to be even more careful than in recent drought years.
“The majority of our starts, and nearly all of our catastrophic fires are human caused,” Isernhagen said in a statement from the University of Nevada, Reno.
Mountain forests face another challenge. Dawn Johnson, Warning Coordination Meteorologist at the NWS in Reno, explained that losing snowpack this early means heavy timber can become drought-stressed much sooner than usual, turning it into a fire hazard months earlier than normal. A cooler storm pattern expected in early April might bring some relief, but experts warn it may be too little, too late to make a real difference.
Eleven Years. No Exceptions.
The Nevada heat wave wasn’t an isolated event. It happened during the longest stretch of global heat ever recorded.
The WMO’s State of the Global Climate 2025 report, released on March 23, confirmed that every year from 2015 to 2025 is among the hottest ever recorded. Depending on the data, 2025 was either the second- or third-warmest year since records began, with temperatures about 1.43°C above pre-industrial levels. Atmospheric CO₂ reached its highest level in 2 million years, and ocean temperatures set a new record for the ninth year in a row.
UN Secretary-General António Guterres put the streak in stark terms: “When history repeats itself eleven times, it is no longer a coincidence. It is a call to act.”
The report also introduced a new measure called Earth’s energy imbalance (EEI). This tracks the difference between the energy the planet receives from the sun and the energy it sends back into space. In 2025, EEI was at its highest since records began in 1960. Surface temperatures, which get most of the attention, only show about 1% of the planet’s extra heat. Over 91% is absorbed by the oceans, which have taken in the equivalent of about 18 times the world’s total annual energy use each year for the past 20 years. EEI gives a clearer picture, showing that the planet is becoming more out of balance.
“In 2025, heatwaves, wildfires, drought, tropical cyclones, storms and flooding caused thousands of deaths, impacted millions of people and caused billions in economic losses,” said WMO Secretary-General Celeste Saulo. She added that the changes driven by human activities “will have harmful repercussions for hundreds — and potentially thousands — of years.”
What’s happening in the Western U.S. matches the WMO’s global findings perfectly. The report highlighted major glacier loss in 2025 along North America’s Pacific coast. These events aren’t separate—they’re both signs of the same warming trend, just showing up in different ways and times.
“We seem to be entering this new era where temperatures will be significantly higher than what they were ten years ago,” said climate scientist Sarah Perkins-Kirkpatrick of Australian National University. She explained that the changes of the past three years can only be explained by climate change.
What About the Cold in the East?
This is where things get both surprising and important.
If you live in the Northeast, Midwest, or Southeast, 2025 might not seem like a record-warm year. Some parts of the eastern U.S. have had cold snaps and severe winter weather that made national news. So how does that fit with 11 straight years of record global heat?
This actually makes sense in climate science. Climate change doesn’t warm every place at the same time. Instead, it disrupts atmospheric patterns like the polar vortex, which usually keeps cold air over the Arctic. As the Arctic warms much faster than the rest of the planet—about four times the global average, according to NOAA—the polar vortex weakens and shifts, letting cold air move into areas that don’t usually get it.
In other words, the same forces causing record heat in Nevada are also behind the unusual cold in the eastern U.S. These aren’t opposites—they’re both results of a destabilized climate system. Weather feels local, but our climate is shared. When the West is hot in March and the East is cold, both are signs of the same disrupted system.
What You Can Do
- If you live in the West, check current wildfire risk conditions through the National Interagency Fire Center and understand your local evacuation routes and readiness steps before fire season peaks.
- Lower the risk of starting fires. Most wildfires are caused by people, so be extra careful during high-risk times. Don’t have campfires during bans, avoid dragging chains on your vehicle or trailer, and make sure your equipment doesn’t create sparks.
- Support climate policy at both the state and federal levels. Reach out to your Congressional representatives. The WMO data shows the trend is clear. The decisions we make now will shape how severe fire seasons are in the future.
- Cut your home’s carbon footprint by using energy efficiently, choosing cleaner transportation, and making changes to your diet. One person’s actions won’t solve the global problem, but when many people make changes, it can have a real impact on emissions.
- If you live in the eastern U.S., don’t let cold winters make you ignore climate data. Pay attention to what’s happening across the country—the same atmosphere connects us all.
