The urban tree canopy in Denver is one of the sparsest in the country. In 2020, when Linda Appel Lipsius became executive director of the decades-old Denver Urban Gardens (DUG) network, which oversees more than 200 community vegetable gardens throughout six metro Denver counties, she wanted to continue increasing community access to fresh food—a longtime goal of the garden program. But she had another aim, too: increasing the city’s tree coverage. Appel Lipsius decided to build a system of food forests throughout the Denver area. These dense, layered plantings incorporate fruit-bearing trees with other perennials to mimic natural forests. Now, DUG oversees 26 food forests, with 600 or so fruit and nut trees and 600 berry bushes. While urban trees are recognized for their multiple benefits, including cooling and carbon drawdown, “there are not a lot of players in Denver, or even in most cities around the country, who are focused on food trees,” Appel Lipsius said. “We were able to step into this space to help build and bolster the canopy while adding food-producing perennials.” Neighbors are welcome to enter and harvest a wide assortment of fruits, nuts, and berries. Beyond providing fresh food in neighborhoods that need it most, these agroforests reduce the urban heat island effect, create pollinator habitat, and combat pollution and climate change by absorbing and filtering harmful gases.

When Mount Saint Helens in southwestern Washington erupted on the morning of May 18, 1980, the stratovolcano spewed a plume of debris high into the earth’s atmosphere and spread ash to at least eleven nearby states. But despite the appearance of a mountain-side extinction event, life was already regenerating. Just 10 days after the eruption, the geomorphologist Fredrick Swanson surveyed one of the lahars with colleagues and noticed something intriguing. In the rubble, fine, filament-like threads had attached themselves to some of the smaller pebbles and stones cast out of the volcano’s center. What Swanson was witnessing was the phenomenon of “phoenicoid fungi,” aptly named in a nod to the mythical phoenix rising from the ashes. Fungal organisms such as these are often the first responders to blast zones and wildfire burn areas where the decomposing landscape serves as a smorgasbord for their biological needs. The fungi used for environmental clean-up come in a variety of shapes and sizes. Oyster mushrooms ... can break down petroleum and hydrocarbons, putting them top of the list when it comes to cleaning up deadly oil spills. A 2023 study conducted in Massachusetts, commissioned by MassDOT, found that there could be benefits to integrating mycelium into the state’s pre-existing stormwater management infrastructure to serve as a filtration system to improve water quality.

It wouldn’t be wrong to say Sam Shoemaker crossed the ocean on a mushroom. This August, the Californian artist launched his 14-foot kayak off Catalina Island and paddled for 12 hours across the 26.5-mile Catalina Channel to San Pedro. The brownish-white boat itself [was] “a boat made entirely from a single mushroom growing outside my studio,” Shoemaker explains — the world’s largest mushroom boat. He built it from wild Ganoderma polypore collected near his LA studio, propagated in a hemp-and-sawdust substrate for about four weeks, molded into kayak form and dried until it became “a strong, hydrophobic and inert, cork-like material.” Mycelium, the interconnected root network of a fungus such as Ganoderma polypore, can grow to hundreds of acres. The boat was sealed with locally sourced beeswax, using no synthetic materials. Shoemaker’s multiyear project wasn’t commercial — he is simply interested in demonstrating mushrooms’ potential. His invention is part of AquaFung, a term coined — and a movement inspired — by artist Phil Ross that hopes to one day replace Styrofoam and other materials that go into water with fungi, as part of the nonprofit Open Fung. In their quest, Shoemaker and Ross are members of a sprouting global community of artists, engineers, high-end designers and environmentalists, intent on producing sustainable inventions from mushrooms. For Ross, mycelium is not just a material but a mystery and companion.

Each planting season, Claudia Bashian-Victoroff ventures out into Bole Woods. Laced throughout, weaving an intricate, microscopic web, are the mycorrhizal fungi she’s after — fungi that have spent 400 million years learning to live in symbiosis with plants, including the trees throughout Bole Woods and at least 80 percent of all species on the planet. Bashian-Victoroff doesn’t need much soil. A single spoonful can contain miles of fungal hyphae and filaments, engaged in an ancient evolutionary exchange with the trees to which they’ve bonded. The fungi gather up water and nutrients, and deliver them to the trees. In return, they receive carbohydrates developed through photosynthesis, which they fix into the soil as they grow. It’s a prosperous cycle, and Bashian-Victoroff is among a growing global community of researchers and conservationists taking advantage of this relationship to restore forests and other degraded ecosystems. Their goal: Promote the health of the soil beneath our feet and the plants it supports, sequester carbon and make agriculture more sustainable. Mycorrhizal fungi can be an important part of a broader suite of climate solutions, says Anne Polyakov, a fungal conservation and restoration scientist with the Society for the Protection of Underground Networks, or SPUN, which recently used machine learning to map the planet’s mycorrhizal networks in an effort to promote conservation.

Farmers Alberto Gómez, José Castillo and Javier Castillo arrive with their selected seeds, stored in shigras – hand-woven shoulder bags – as has been done for generations. In San Lorenzo, they call themselves “seed guardians” for their role in protecting this living heritage and passing it down the generations. [They] are among the farmers supporting draft legislation, under review by the lower house of the Colombian parliament, that would ban genetically modified (GM) seeds, which they claim threaten their traditions, livelihoods and food sovereignty. The initiative has the backing of Indigenous, peasant and environmental organisations, but faces opposition from agribusiness and sectors that support GM. In San Lorenzo, the rejection of GM seeds evolved into organised political opposition after people detected the use of such seeds in nearby crops in 2012. They then feared that GM seeds might cross-pollinate with their native varieties, altering their traits and threatening their ability to preserve them. The alarm prompted them to act. They travelled from village to village, hosted workshops, collected 1,300 signatures and drafted a citizen-led proposal. The initiative was backed by the Seed Guardians of Life Network, a national platform comprising farming and environmental groups, as well as local collectives and the municipal government. It was formally submitted to the town council. In 2018, San Lorenzo declared itself a GMO-free territory.

The latest figures and the statistical yearbook "The World of Organic Agriculture" was presented on 11 February 2025 at BIOFACH, the world's leading trade fair for organic food in Nuremberg. The global organic farming area increased by 2.5 million hectares in 2023, reaching almost 99 million hectares. The sales of organic food reached nearly 136 billion euros in 2023. The 26th edition of the yearbook "The World of Organic Agriculture", jointly published by FiBL and IFOAM – Organics International, shows that the growth in area and number of farms in 2023 exceeded that of previous years, particularly due to increases in Latin America. Data were provided by 188 countries. By the end of 2023, 98.9 million hectares were managed organically, marking a 2.6 percent increase (+2.5 million hectares) from 2022. Latin America experienced the largest increase, adding 1 million hectares (10.8 percent growth), while Africa recorded the highest relative growth, expanding by 24 percent to reach 3.4 million hectares. Oceania remains the leading region for organic farming, with 53.2 million hectares, accounting for more than half of the global organic area. It is followed by Europe, which has 19.5 million hectares, and Latin America, with 10.3 million hectares. By country, Australia leads with 53 million hectares, followed by India (4.5 million hectares) and Argentina (4 million hectares). There are notable increases observed in Vietnam, Sri Lanka, and Burkina Faso.

As I approach India's first Garbage Cafe on a cloudy and foggy winter day in early 2025, the smell of hot samosas immediately makes the place feel cosy. Inside, people are sitting on wooden benches holding steel plates filled with steaming meals, some chatting, others eating quietly. Every day, hungry people arrive at this cafe in Ambikapur, a city in the state of Chhattisgarh in central India, in the hope of getting a hot meal. But they don't pay for their food with money – instead, they hand over bundles of plastic such as old carrier bags, food wrappers and water bottles. People can trade a kilogram (2.2lb) of plastic waste for a full meal that includes rice, two vegetable curries, dal, roti, salad and pickles, says Vinod Kumar Patel, who runs the cafe on behalf of the Ambikapur Municipal Corporation (AMC), the public body which manages the city's infrastructure. Every morning, [Rashmi Mondal] sets out early on the streets of Ambikapur in a search for discarded plastic – anything from old food wrappers to plastic bottles. For her, collecting such detritus is a means of survival. "I've been doing this work for years," Mondal says, looking at the small pile of plastic she has gathered. Previously, Mondal used to sell the plastic she collected to local scrap dealers for just 10 Indian rupees (£0.09/$0.12) per kilogram – barely enough to survive on. "But now, I can get food for my family in exchange for the plastic I collect. It makes all the difference in our lives."

While trying to come up with a pesticide solution to kill off bollworms, Dr Robert Mensah had his eureka moment. It was the 90s, and in Australia bollworms were devastating cotton farms. He experimented and eventually came up with a simple food spray, “a mixture of food ingredients, yeast and sugar-based, diluted in water and applied to crops. It emits an odour which is picked up by beneficial predatory insects and attracts them to the fields where they kill pests.” It was the beginning of an international grassroots campaign, in which Mensah has worked with various charities to teach people about this sustainable farming method. Ever since the dangerous side effects of pesticides became widely known, alternatives have been sought. This approach to farming, which reduces our reliance on pesticides, is called integrated pest management. In 2005, Mensah took food sprays to Benin, where the Pesticide Action Network (PAN UK) was helping farmers transition to organic farming. There, the misuse of chemical pesticides was seriously damaging people’s health. The food sprays – cheap, safe and effective – caught on with farmers in Benin where thousands now use the technique. From there, Mensah took food sprays to southern Ethiopia, where they were also trialled successfully on vegetables ... and then to Vietnam where they were used successfully on maize. Another charity, Better Cotton, is now trialling food sprays in India ... where they’ve trained 214,000 farmers to use sprays.

Small was what the couple wanted. Ms. Boyle is from Vermont, and while studying at Emerson College in Boston, she worked an office job connected to the local food movement. But she quickly realized she wanted to be outside with her hands in the earth. Mr. Wolcik graduated from the University of Massachusetts Amherst, where he studied sustainable agriculture and community food systems. He, too, realized he wanted a life close to the soil. They met while working at a nonprofit farm outside Boston and soon discovered they shared a dream about buying their own acreage to grow food and flowers. They weren’t interested in a massive operation. Instead, their vision included no-till growing methods, hand tools, and a desire to build a “human scale” production system. They also wanted to make their living entirely from their farm – something increasingly difficult to do in New England. Over the past 60 years, the region has lost 80% of its farmland. They joined a community actively building a new storyline around farming, food, and resilience in New England. Here, in this part of little Vermont, statewide population 648,000, a coalition of farmers, nonprofits, and residents is eschewing mainstream beliefs about what makes agriculture successful and what it means to create a prosperous economy. Instead, they are building a system in which farmers are able to make a living and residents can eat healthy food grown nearby.

Everywhere around the world, regenerative farmers prove that we can generate ecological, social and economic profit whilst producing food. These farms are no longer part of the climate, soil, biodiversity, water and health crises, but actively contribute to solutions. Because whilst they sow, grow and harvest, they ensure that their landscapes, communities and local economies become increasingly healthy and resilient. However new or revolutionary this seems, it is not. In fact, regenerative farming goes back to the basics and places indigenous principles – such as the idea that all life is interconnected – at the heart of food production. And just like indigenous communities, regenerative farmers look beyond the short-term and desire to pass on their land in a better state than they found it. In nature, different plants, flowers, herbs, nuts and fruits grow side by side in the same ecosystem. Whilst they grow, they add and remove different nutrients from the soil, thus keeping it balanced. At the same time, a wide variety of insects and other animals are attracted by the biodiversity, keeping each other in check and making sure that no species can ever become a pest. This ensures that all life can flourish. Many regenerative farms sell their produce directly to consumers, therefore cutting out the middleman, or even opt for a membership model where people can become members of the farm for the duration of a harvest season, called Community Supported Agriculture.

Thousands of infant sequoia and coastal redwood saplings, each the size of a thumb, sprout beneath grey foil and growing lamps in bus-size greenhouses. In the next room are their juvenile siblings, five to eight inches tall: sequoias, coastal redwoods, oaks and a hundred other tree species form the Archangel Ancient Tree Archive (AATA), a living library of the world’s mightiest trees. These are not just any saplings — they all are descendants of so-called champion trees, specimens of exceptional size, age and resilience. At 75, David Milarch is trying to save the world’s last old-growth forests from extinction — by using their DNA to help reverse climate change. The need, Milarch notes, is urgent: “Ninety-eight percent of the old-growth forest has been logged,” he explains. “We have to save the remaining two percent.” Unlike with other tree planting initiatives, Milarch puts plans in place to nurture the saplings for generations to come. To make this possible, he and Arboretum Detroit work with schools. “We empower the kids. We teach them, we give them the materials, and we check in on them,” Milarch explains. “We’re propagating the propagators. That’s the paradigm shift.” Each child gets to name a sapling, “because kids need to connect with nature,” Milarch says. And later on, when the kids face hardship, Milarch points out, “they can always run to their tree and get some solace.”

Collaborating with robotics engineers and Italian 3D printer manufacturers, a Japanese company is building “homes of earth” made primarily from soil. Lib Work, Ltd. completed their first 3D-printed earth home in Yamaga, Kumamoto on July 22, calling their creative process “uncharted territory where tradition and convention offered no guide”. With an eye toward recycling, sustainability, and reduced carbon emissions, Lib Work focused on combining 3D-printing with natural materials enhanced for strength, constructibility, and design quality. The walls of the completed Lib Earth House Model B use no cement (which produces industrial waste). Instead, they utilized only naturally derived materials with soil as the primary component to create sustainable earthen walls. Compared to the previous model (Model A) that used some cement, the building’s strength has improved approximately fivefold while significantly reducing CO2 emissions from the manufacturing process itself. The walls contain cutting-edge sensors as part of a wall condensation monitoring system that monitors in real-time the temperature and humidity inside the walls. This system enables the house to manage its own condition by detecting condensation in advance to maintain a long-lasting, comfortable living environment. Additionally, the homes include remote operation of air conditioning, lighting, and bath controls via smartphone or dedicated monitor. It also features an off-grid energy system.

Equipped with her own tailored bee suit and a hood to cover her floppy ears, Maple — a former police dog — has an important retirement task: helping save thousands of honeybee hives. The canine has spent the past five months sniffing Michigan bee colonies for American foulbrood, a highly contagious bacteria that’s fatal to the insects. Maple, an English springer spaniel, uses her extraordinary sense of smell as a “high-speed screening tool” to prevent beekeepers from having to manually inspect every hive. American foulbrood only becomes detectable to humans by smell when it reaches severe infection, at which point the colony risks death, said Meghan Milbrath, a researcher and assistant professor of entomology at Michigan State University. The ultimate goal is for Maple’s work to serve as a blueprint for teaching canines to detect honeybee diseases. It’s part of a larger bee conservation effort in a record-breaking year for colony death in the United States ... primarily driven by pesticides, pathogens, poor nutrition and pests. Although Maple’s new “target odor” is distinct from her previous job ... the fundamentals remain the same. Handlers expose the canines to a scent, offer a reward and teach the dog to conduct an action that means they’ve found the odor they’re looking for. In Maple’s case, she sits when she detects the smell. [Handler, Sue] Stejskal said she has to train Maple to be familiar and comfortable with the new environment so the pup can focus on the target odor.

Regenerative agriculture offers a way to move beyond what I call the ‘dead Earth assumption’ – this mechanistic belief that the Earth is made up of lifeless raw materials meant for extraction. Because that’s the foundation of industrial agriculture: all it cares about is how many tons of food it produces, with no regard for soil health, biodiversity or the wellbeing of farmers. Regenerative agriculture, on the other hand, shows us the opposite. It means collaborating with nature and recognizing that we are all living organisms on a living Earth. That is what farming should be about: regenerating the potential of the living soil, the living seeds, the living water, the living insects, and the entire web of life. By embracing this potential, we can also transform the way we relate to nature. Because regeneration writes its own poetry – it brings the Earth back to life again in our minds and, in doing so, our relationship with the Earth is being regenerated as well. Some people say: ‘You’re naive, because companies will always win.’ But I don’t think that companies will win, and I will give you a reason why. The first corporation ever created was the East India Company in 1600, but after the revolt of the peasants in 1857, they shut down in 1858. So the first corporation that was created to rule the world, was shut down by peasants. In today’s world, meaningful change can happen too, when we unite. It all comes down to nurturing the living soil and the living seed.

Could baby poop and fungi work together to tackle landfill waste? That's the idea behind a new product launched by an Austin, Texas-based startup that sells disposable diapers paired with fungi intended to break down the plastic. Each of Hiro Technologies' MycoDigestible Diapers comes with a packet of fungi to be added to the dirty diaper before it is thrown in the trash. After a week or two, the fungi are activated by moisture from feces, urine and the environment to begin the process of biodegradation. An estimated 4 million tons of diapers were disposed of in the United States in 2018, with no significant recycling or composting. Diapers take hundreds of years to naturally break down. That means the very first disposable diaper ever used is still in a landfill somewhere. To tackle this, Hiro Technologies turned to fungi. These organisms - which include mushrooms, molds, yeasts and mildew - derive nutrients from decomposing organic matter. In 2011, Yale University researchers discovered a type of fungus in Ecuador that can feed on polyurethane, a common polymer in plastic products. They figured the fungus, Pestalotiopsis microspora, would be capable of surviving on plastic in environments lacking oxygen, like landfills. Hiro Technologies co-founder Tero Isokauppila, a Finnish entrepreneur who also founded medicinal mushroom company Four Sigmatic, said there are more than 100 species of fungi now known to break down plastics.

Hemp is one of the most sustainable materials available to manufacturers because it's cheap to grow, uses little water, doesn't need any toxic pesticides, and can absorb more carbon than trees. Hemp batteries have their own advantages, too. These batteries use lighter and more widely available materials like sulfur, boron, and hemp instead of the heavy metals used in traditional lithium-ion batteries. Some EVs use a device called a supercapacitor, which stores energy through static electricity rather than a chemical reaction, like in conventional batteries. In these batteries, a material called graphene is used. But graphene is expensive. To create ... "cannabis cars," scientists use hemp bark — a waste product created by cannabis plants — and cooked it to make a substance that resembles graphene. Hemp lasts longer than graphene. It also stores more power and is easy to source. Son Nguyen, Bemp Research's founder, told EnergyTech that the company's lithium-sulfur battery can help solve shortages in the EV battery supply chain. "Sulfur is very abundant. Boron is also relatively abundant, with the biggest boron mine being in California," Nguyen said. "Being an American company, our focus right now is to make batteries for American electric vehicles, and we do not see any supply chain problems. Bemp batteries are less reliant on rare earth metals from around the globe and thus will help U.S. national security."

An unlikely natural ally in the fight against microplastics has been discovered. Researchers in China have found that invasive water hyacinths are adept at absorbing microplastics without harm to the plant itself. Experiments against a control group showed that plastics were mostly trapped on the outside of the water hyacinth's root systems. The few that get inside the plant are quickly separated before nutrients get to the leaves. Typically, plants exposed to microplastics suffer ill effects. Water hyacinths are native to South America. Two plants were able to produce 1,200 daughter plants in four months, according to one study. Any given population of water hyacinth can double in size in six days. Once dropped into a new foreign habitat, invasive species ... can squeeze out native species, reduce biodiversity, and eliminate vital ecosystem services. Not long ago, Arkansas had to issue a statement on the threat water hyacinths posed to agriculture. On the flip side, microplastics are a scourge. They'll often end up in the fish we catch, and once eaten by humans, they can cause problems with the endocrine, immune, and reproductive systems. Despite their rapid proliferation, it may still be worth strategically deploying water hyacinths. Other studies have shown that water hyacinths can also absorb heavy metals and agricultural runoff. Meanwhile, enterprising individuals have been able to take the excess biomass of the plants and turn it into briquettes and bioplastics.

What if your heating and cooling worked during power outages, and you could count on it becoming more efficient and climate-friendly over time? That's the promise of district heating and cooling or district energy, where entire communities share a heating and cooling system. That allows them to tap into many low-carbon energy sources they couldn't before, more efficiently than any individual building could. As governments look to tackle carbon emissions from buildings — the third largest source in Canada behind the oil and gas industry and transportation — it's an idea that more of them are considering and implementing. Peter Ronson is chief operating officer for Markham District Energy (MDE), a network in a Toronto suburb that heats and cools 14 million square feet in more than 200 buildings, including condo buildings up to 44 storeys tall, a hospital, data centres, hotels and two schools. Some, like the data centres, produce a lot of heat, while others may use lots of hot water. "We got all sorts of stuff on the system," Ronson said. "When [some are] throwing away energy, I can recover and give it to somebody else." That kind of heat-sharing is efficient. Excess heat in the system can also be stored (underground in water or rock, for example) ... and much more cheaply than electricity. All that means converting buildings that burn fossil fuels to district energy can potentially put less strain on the grid than electrifying individual buildings using heat pumps or baseboard heating.

A team of researchers searching for safe, sustainable, and biodegradable alternatives to plastics presented a new type of transparent material at the American Chemical Society (ACS) spring meeting. Unlike previous transparent “wood” designs that sacrifice some biodegradability for strength by including certain types of plastics, the team said its eco-friendly see-through material is made with all natural components. Potential applications for the plastic alternative include electronic device screens, wearable sensors, coatings on solar cells, and transparent wood windows. Bharat Baruah, a professor of chemistry ... said his woodworking hobby led him to research efforts to create transparent wood. He quickly discovered that successfully created transparent wood materials were enhanced with epoxy, a type of plastic, to increase its strength, sacrificing some biodegradability. The professor decided he should see if there were better alternatives. After enlisting Ridham Raval, a Kenneshaw State undergraduate student, to help, the duo used a vacuum chamber, sodium sulfite, sodium hydroxide, and bleach to remove lignin and hemicellulose, two of wood’s three components, from a sample of balsa wood. What remained was a paper-like layer of cellulose filled with tiny pores. Instead of refilling the pores with epoxy, the team soaked the cellulose layer in a mixture of egg whites and rice extract. They were “left with semi-transparent slices of wood that were durable and flexible.”

Researchers at ETH Zurich have designed a sustainable method to extract gold from electronic waste using a byproduct of cheese production. Electronic devices, from smartphones to laptops, contain small amounts of gold due to its excellent conductivity and resistance to corrosion. With the rapid turnover of electronic gadgets, e-waste has become the fastest-growing waste stream globally, reaching 62 million tonnes in 2022, and only 22.3 percent of this was formally collected and recycled, leaving vast amounts of valuable materials unused. Professor Raffaele Mezzenga and scientist Mohammad Peydayesh led the ETH Zurich team in developing a method that utilizes “whey”, the liquid byproduct of cheese-making. By processing whey proteins into amyloid fibrils, they created a sponge-like aerogel capable of selectively absorbing gold ions from acidic solutions derived from e-waste. Professor Mezzenga stated, "The fact I love the most is that we're using a food industry byproduct to obtain gold from electronic waste. You can't get much more sustainable than that!" In laboratory tests, this aerogel successfully extracted gold from dissolved computer motherboards. The sponge drew out gold that was about 90.8 percent pure, yielding a 22-carat nugget weighing approximately 450 milligrams. The research team is also exploring the use of other food industry byproducts, like pea protein and fish collagen, to diversify the sources of the aerogel. The process is economically viable, with operational costs significantly lower than the market value of the recovered gold, unlike traditional gold extraction techniques that rely on toxic chemicals like cyanide.
