Today, a trip to the supermarket reveals dozens of ice cream and potato chip flavors, but the milk comes from only a few cow breeds, and only a handful of potato varieties are used. A study by the International Potato Centre predicts that 13 wild potato species could be extinct by 2050. Apples are also disappearing; a 1905 book titled “The Apples of New York” documented hundreds of varieties, but most are now gone, including the vanilla-flavored “Virginia Greening” from the 1700s. Like milk, apples, and potatoes, food varieties worldwide are disappearing at an alarming rate, reports PBS in The Lexicon of Sustainability.

According to the UN Environment Programme, over the past 100 years, more than 90 percent of crop varieties have disappeared and today, just nine plant species account for 66 percent of total crop production. “Over the past 50 years, we are seeing that diets around the world are changing and they are becoming more similar – what we call the ‘globalized diet’,” Colin Khoury, a scientist from the Colombia-based International Center for Tropical Agriculture, told BBC. “This diet is composed of big, major crops such as wheat, rice, potatoes and sugar.” He added that the decline in crop diversity in the globalized diet has limited the production of more nutrient-rich foods. According to Khoury, the crops recording a decline were millets, rye, yams, sweet potatoes, and cassava in the past decade.

Although the world’s croplands have over 50,000 edible plants, just three of them, including rice, maize, and wheat provide 60 percent of the world’s food energy intake, per FAO. So, what is happening? Why is crop diversity on the edge of extinction? The answer lies in seeds, according to PBS. Traditionally farmers grew and mutually shared these seeds, but today most seed production is controlled by a selected few companies. Plus, the DNA of seeds also seems to have been altered, which is called “genetic modification.”

Another factor is “farming.” With the advent of advanced technology, modern farming is way different from the one done in the bygone times. These intensive farming practices are causing the soils worldwide to degrade in quality, per BBC. As the layer of fertile topsoil becomes thinner, it becomes much less capable of growing food. The result is a precarious vanishing of crops. To solve the problem of crop extinction, many people are stepping forward. For instance, nowadays, there are seed banks like “The Svalbard Global Seed Vault,” also called “Doomsday Seed Vault” that preserves the seeds from around the world.

Besides these banks, experts suggest that farmers gain an understanding of “Agricultural biodiversity,” also called “agrobiodiversity.” According to The Counter, agrobiodiversity is the foundation of agriculture and food, resulting from the connection between microorganisms, plants, and animals, as well as the quality of nutrients in the soil.

Plus, the solution also lies in what people eat and how they view food and agriculture. “The revolution starts here, on our plates, by looking at the pillars of our diets and by making simple changes. The way to take back this power for ourselves is to understand why we eat what we eat. And to understand what we’re losing—so we know what to reclaim,” wrote Preeti S. Sethi in her book, “Bread, Wine, Chocolate: The Slow Loss of Foods We Love.”

    Scottish children are helping penguins find mating partners with these tiny, painted stones

    “I would cry if a penguin picked MY pebble 😭 It’s a life goal”

    During mating season, male gentoo penguins are tasked to find pretty and smooth rocks to present to prospective mates. This is meant as a gesture to woo them and to be used to build a nest with them, too. Well, this season, the penguins at the Edinburgh Zoo in Scotland got some help.

    Kids being supported by the Edinburgh Children’s Hospital Charity gathered together to paint pebbles with vibrant colors for the penguins. The hospitalized children do this every year with the first stone traditionally placed in the penguin enclosure. The children often watch a livestream of the gentoo penguin enclosure to see the penguin pick their favorite rocks that they’ve painted.

    Commenters sound off on the penguins’ pebbling

    The Edinburgh Zoo posted this year’s pebbling pickings on Instagram, delighting the commenters:

    “I would cry if a penguin picked MY pebble 😭 It’s a life goal lol.”

    “This is just brilliant! How wonderful to see a creative health initiative that actively connects the children with a purpose like this!”

    “This is heartwarming ❤️❤️❤️”

    “This is brilliant for the penguins and the children! Can’t wait to see the beautiful nests.”

    “My grandson painted a pebble he’s hoping it gets picked.🤞🤞🤞”

    “Penguin pebble pilfering season is upon us! So pleased it makes so many people (and penguins) happy.”

     “Oh no, now I’m questioning if penguins have favourite colours.”

    “Any that aren’t picked would make an awesome rock garden that kids visiting the zoo could pick from!!”

    “This is the cutest thing I have seen probably ever.”

    Pebbling practices for human relationships

    As mentioned, this mating ritual called “pebbling” is a gesture made by male penguins to their mate to not just build a nest. It’s their version of saying, “I saw this and I thought of you.” In fact, psychologists and couples therapists recommend adopting a version of pebbling for human relationships.

    Now to “pebble” in dating or married relationships doesn’t literally mean giving your partner rocks (unless they’re a geologist that would love that sort of thing). For humans, pebbling your partner means to share or give a small gift like a flower, toy, or object that has some meaning to one or both of you. It doesn’t always have to be a gift either, but it could be a photo, social media post, or a meme you can text them. It’s essentially anything that conveys “I saw this and thought of you” in order to showcase affection to them and initiate closer conversations.

    Pebbling isn’t just for romantic couples either. Many autistic people find it more difficult to navigate socially due to high anxiety, sensory sensitivities, or having trouble interpreting social cues. By texting a GIF to a friend, giving a small flower to their parent during a walk, or other such pebbling, it allows some autistic people the ability to communicate their affection and connection without the pressure of using words.

    Whether it’s a colorful rock or something else, pebbling can be a valid form of communication between friends, partners, or potential mates. It all depends on who you choose to build a nest with.

  • Scientists have created a leather clothing alternative made entirely from mushrooms that looks and feels like the real thing

    Austria’s scientists have created a leather made from mycelium. Growing mushrooms in low-oxygen chambers allows researchers to craft an alternative material that feels and looks like traditional leather. The finished textile is strong, flexible, and even fire-resistant.

    Manufacturers grow the material instead of harvesting it from animals. After it reaches the desired thickness, they apply non-toxic enzymes to keep it fully biodegradable. The vegetative part of the fungus grows into a dense mat over a matter of days. Above all, it avoids the environmental impact of traditional leather production.

    Alternative leather made from mushrooms

    This is not science fiction; fungal fabric has grown from a curiosity into reality. A 2025 report listed the benefits of mushroom leather as having a lower carbon footprint. It begins with a substantial reduction in water use. Growing mushrooms, compared to raising cattle, requires a fraction of the water.

    Secondly, the product breaks down naturally without microplastic contamination. Using enzymes that cross-link the fibers results in a material free of blended toxic materials.

    Moreover, by creating the right environment—a low-oxygen chamber with a nutrient-rich substrate—the mushroom mat can be grown in a matter of days.

    Lastly, mushroom leather is naturally fire-resistant. There’s no need for harmful chemicals to treat the textile. In addition, clean up requires mild soap and lukewarm water.

    A 2026 study in ScienceDirect confirmed the fungal mycelium as an eco-friendly alternative to traditional and synthetic leathers. It demonstrates structural integrity and favorable thermal stability.

    Is the public ready for vegan leather?

    People have conflicting thoughts, as seen in the comments on the Instagram post. Some individuals are excited and encouraged by the possibilities. Others, however, are less impressed:

    “I’m ready for it. How do we buy it?”

    “Make it affordable and common!”

    “As long as the final product keeps being painted and coated with chemicals, the purpose of the product is merely green washing.”

    “bio degradable? sorry your shoes were eaten by mold after the rain.”

    “Where we can buy this leather?”

    “Unless we’re talking about aprons/gloves for welders or blacksmiths (which is a fairly niche market), flammability isn’t something most people that wear leather are concerned about.”

    Fashion looks for sustainable, yet affordable materials

    Fashion leaders are looking to incorporate more sustainable fabrics into their creations. A 2025 post on Open Forem explored material choices for leading industry fashion designers in 2025. For example, more familiar textiles like polyester, organic cotton, and wool made their traditional rounds. But there was an effort to use plant-based leathers, too.

    Mushroom mycelium leather was a hot choice for its low environmental impact, its short creation time, and its customizable texture and thickness.

    Other exotic materials included banana fibers, seaweed-based fabrics, and Piñatex, a natural, low-impact textile made from pineapple leaf fibre. Designers fashion the plant-based material into vegan handbags, shoes, and wallets.

    A 2026 article in Vogue revealed that Gucci seeks more sustainable ways to produce leather products. The luxury brand began a campaign for vegan alternative leather back in 2021.

    Despite commercial adoption remaining somewhat limited, mushroom leather continues to attract attention for its eco-friendly production and versatility. Grown on agricultural waste while remaining fully biodegradable are cornerstones of this remarkable material.

  • Scientists create environmentally friendly plastic replacement from shrimp shells

    Plastic waste has been a growing global issue for years. The United Nations Environment Programme says that 19 to 23 million metric tonnes of plastic waste leaks into lakes, rivers, and oceans each year. Given the threat microplastics pose to animal and human health, efforts to find green replacements have intensified—and they’re working. Scientists from Singapore and Spain have found a strong, potentially viable replacement for plastic made from shrimp shells.

    A research team based at the Singapore University of Technology and Design and the Institute for Bioengineering of Catalonia in Barcelona has made a biodegradable plastic alternative out of chitosan. Chitosan is a compound created by combining shrimp shells with trace amounts of nickel. It contains a structural molecule found in the shells of crustaceans and insect exoskeletons. Usually discarded as a waste byproduct of shrimp and crab processing, chitosan is commonly produced during seafood preparation and commercial fishing.

    The issue with chitosan, though, was that it weakens and dissolves in water. That is, until recently.

    How chitosan got stronger

    Dissolving chitosan flakes into a weak acetic solution and mixing them with dissolved nickel chloride and water produced surprising results. Scientists then poured the mixture into molds to dry. The process yields a thin, green-tinted film with the strength of commonly used plastics like polypropylene. Even better, when submerged in water, the film grows 50% stronger. This increased durability matches the characteristics of polycarbonate and PETG, plastics commonly used in commercial single-use water bottles.

    Researchers then stress-tested the chitosan material by molding it into cups and containers. They were able to confirm it could hold water without leaks. In terms of biodegradability, the chitosan material reached its half-life in four months in a standard soil burial test. By contrast, most commercial plastics can take centuries to decompose under similar conditions.

    Researchers found that this is not only a better biodegradable plastic alternative, but also one that produces zero waste during creation. When the chitosan/nickel film is submerged, about 87% of the nickel washes out. That wash water can then be reused again and again from one batch of chitosan to the next. According to the researchers, the nickel content of a single AAA battery would provide enough nickel to manufacture more than a dozen chitosan drinking cups.

    The potential future

    Rigorous testing to assess the material’s limits for medical use and consumption still needs to be done. That said, the Food and Drug Administration has already approved products containing chitosan and nickel individually in the past. Barring any troubling research about their combined safety, the outlook is quite positive for future use.

    Hopefully, seafood and battery waste can be reduced, helping lower plastic waste in a three-way win for the environment.
