1 . Chaudhary quietly weaves together lengths of ropes, binding them with grass collected from the riverbank. She skillfully shapes the materials into a jewelry box. Meanwhile, she’s instructing a group of women to work out the materials. The ropes used were once the lifeline for climbers tackling Nepal’s mountains and were then discarded (扔掉). They are now finding new life, transformed by skilled hands into items to sell.
Acharya, working with the cleaning campaign, owns a waste processing business in Kathmandu, also an advocate for sustainable waste management. “Aluminum and other metal waste go through the recycling process, but we found no way to recycle ropes and gas cans,” she says. It struck her that the non-recyclable waste could be reused, but it wasn’t until she met Maya Rai that a solution emerged. Rai, leading Nepal Knotcraft Centre, helped connect Acharya with Chaudhary’s team of craftswomen in hopes of turning the mountain waste into economic opportunity. “While this seems insignificant compared to waste in the mountains, it’s a start. We aim to connect local expertise, mountain waste and local economy,” says Acharya, proudly displaying a mat made from ropes left on Mt. Qomolangma by climbers. Her goal is to ensure that no waste collected from mountains ends up in a landfill again.
Finished crafts are sold at outlets and exhibitions. The craftswomen are paid according to how many items they make and sell. With flexible hours, the project gives women an opportunity to earn money even as they maintain household responsibilities.
Eventually, Acharya hopes to expand the program to involve more women and process more waste. But progress has been slow. “We still have not found a sustainable business plan to make crafts in large quantities, ”she says. Now, she is searching for cooperators to make a model that serves not only the mountain but the communities. “After all, we are trying to craft a sustainable future.”
Each rope turned into a decorative item is a way to help local women earn a living and keep mountains clean.

2 . Nanako Hama gets a lot of mail, mostly from strangers who live in her home city of Tokyo. In light envelopes, they send locks of their hair, hoping to recycle it.
People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change.
But hair possesses useful qualities and it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks,
Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mats, which are then used to clean up the floating oil.
“Hair is particularly well-suited for this,” says MoT co-founder Lisa Gautier, “That’s because its rough sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.
In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney, in Australia found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair — significantly more than polypropylene (聚丙烯), a type of plastic that’s typically used to clean up floating oil.
Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen (氪), a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.
“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes-for oil and soil, ” Hama says.

3 . Waterways are important for every country around the world. They provide not only water for everyday use but also routes for transport. However, due to industrial activity, many of them are now polluted.
Dakota Perry from the US has experienced water pollution firsthand. The 15-year-old high school girl told Alabama Local News that she spends a lot of time going on boat rides with her dad on the river behind their house. However, the river has become littered with plastic bags, bottles and cups.
Perry wanted to clean up the water so she could continue to enjoy the river. So, with the help of her father, she designed a system to collect and remove trash in waterways.
In May, Perry put forward her solution al the Regeneron International Science and Engineering Fair held in Gcorgia, US, and received a Judge’s Award from the National Oceanic and Atmospheric Administration for her project.
According to the Science News for Students website, her system was inspired by the Dutch Great Bubble Barrier in Amsterdam, which creates a flow of bubbles that trap waste and directs it to a catchment (集水) system. But Perry tried to challenge herself and make her system more environment-friendly.
She planned to create a curtain of bubbles that spanned the river diagonally (对角地).The curtain would stop the floating trash and then push it toward the shore. Once there, a conveying belt run by a solar-powered battery would carry the waste to trash bins.
In her backyard pool, Perry used an air compressor (压缩机) to send air through a pipe full of holes to create a stream of bubbles. She experimented with different amounts of pressure to make sure there would be enough bubbles to form a full curtain. “For the bubble system to actually work and actually collect the trash,” she explained to Science News for Students, “I have to know how much pressure the air compressor is supposed to push out.”
After she tested her system for collecting trash, Perry found that it worked better than expected. Next, she plans to work out how to use the power of the river to run the air compressor.

4 . This summer we witnessed interview teams at the North Pole wearing short sleeve shirts due to the warm weather. A study published on Aug 29 revealed more concerning issues in the supposedly coldest area of the world. Zombie ice from a massive Greenland ice sheet was confirmed to be melting, which would eventually raise global sea levels by at least 10 inches (27 centimeters) on its own, reported Associated Press (AP).
Zombie ice is the kind of ice that is still attached to thicker areas of ice, but is no longer getting fed by larger glaciers. Since glaciers are getting less snow to make up for the amount of ice melted, once the zombie ice is melted, it cannot be re-formed.
Scientists decided to look at the balance of the ice. In perfect equilibrium (平衡),snow in the mountains of Greenland flows down and thickens the sides of glaciers, balancing out what’s melting on the edges, according to AP. But in the last few decades, there is less refill and more melting, creating an imbalance.
Study co-author William Colgan at the Geological Survey of Denmark and Greenland told AP that 3. 3 percent of Greenland’s total ice volume will melt eventually. “Starving would be a good phrase” for what’s happening to the ice, Colgan added.
With a great number of natural resources buried under the earth, areas of melted ice revealed treasures that attracted the world’s richest men. According to CNN, in early August, there was a “treasure hunt” in Greenland. Billionaires, including Bill Gates and others, financially backed KoBold Metals, a US-based mineral exploration company, to explore the rare metals under the glaciers in Greenland. The company told CNN that since there were enough minerals to power hundreds of millions of electric vehicles, the critical resource is capable of powering the green energy transition (过渡).
While investors are taking advantage of global warming, experts express their concerns that the mineral exploration is likely to worsen the local environment, running out of the world’s resources at a faster rate.

5 . An environmental group in Colombia is leading a project to save wild areas in the San Lucas Mountains with the help of coffee growers.
Since 2016, San Lucas areas have been threatened by mining and coca (古柯) planting Gold miners and coca growers make more money than coffee farms. Now the group WebConserva helps link coffee farmers with coffee processors from around the country in order that they can earn more. At the same time coffee farms can serve as boarders around the forests to protect the biodiversity within.
To date, the project includes 10 families who farm 400 hectares of coffee plants. WebConserva said it hopes, in time, 200 families will be included. At that level. 20,000 hectares of untouched forest could be protected. The families promise not to cut down trees to expand their crops or to hunt wild animals. In return, they receive $300 for 125 kilograms of coffee.
Arcadio Barajas is among those taking part. His coffee farm sets up a barrier between cattle farms and forests where wild animals live, thus reducing the possibility of conflict between cattle farmers and wild animals. “Cutting down the forest to plant coca and killing wildlife were against my faith, and now I feel that growing coffee lets me be a good guard of the land,” he said.
Amnobis Romero is a former coca grower and miner. “Many families depended on illegal activities to support their children years ago. Now, we feel it a duty to look after this biodiversity and leave it for future generations,” he said. Activists want San Lucas to be protected as a national park, but the process has been slow. Carlos Valderrama, director of Webconserva, hopes the project can build production system that will last far into the future. “It protects forests, biodiversity and ecosystems at the same time as improving coffee growers’ quality of life,” he said.

7 . It’s no secret that inhaling (吸入) smoke is bad for your lungs. But now, scientists are suggesting smoke may also carry and spread infectious diseases. The theory, published in Science Magazine, is based on research that found wildfire smoke is crowded with thousands of species of microorganisms. Some of these microorganisms, including bacteria and fungal spores, are known to cause disease.
The new research suggests that when a wildfire burns plant or animal matter and disturbs soils, it exposes thousands of species of bacteria and fungi that otherwise might not easily become airborne (空气传播的). You might think the high heat from fire would kill these organisms, but one study mentioned in the article found that some bacteria even multiply post-fire. Scientists say the organisms attach to smoke particles, allowing them to travel thousands of miles across continents.
Dr. Peter Chen, director of the Division of Pulmonary and Critical Care Medicine at Cedars-Sinai Medical Center in Los Angeles, is interested in the theory but somewhat skeptical that the microorganisms in smoke would actually cause infections. Many bacteria and fungi don’t cause lung infections, says Chen, but it’s certainly possible that a significant amount could worsen symptoms in someone with a preexisting lung condition. “I always thought it was the particles in smoke that were causing these issues,” says Chen. “But when I read this, I started thinking: Could it be the microorganisms that are also worsening existing illnesses?”
Whether the microorganisms in smoke actually cause infection or simply worsen potential respiratory (呼吸的) issues, the article raises a new health threat that is “certainly alarming”, says Kelsey Jack, an associate professor of environmental and development economics. This is especially true for lower-income populations, Jack says, because people with fewer means are often more exposed to the environment. If smoke is affecting the air quality in a certain area, the people who work outside, or who have to go to the office on foot or by bike will inhale more smoke than those who drive.
But until more research is done, Chen says the best thing people can do is just follow existing recommendations when air quality is poor—including staying indoors, keeping windows and doors closed, using HEPA filters and running air conditioning.

9 . Amy Fang has recently been asked a lot about how her handbag matches her vest (马甲). A few months ago, they belonged to the same grey jacket that she bought five years ago. “I’ve been telling people around me that if you have clothes that carry emotional value and you don’t want to get rid of them, you can have them upcycled (升级改造),” says Fang.
Fashion’s waste problem places a huge burden on the environment, awareness of which partly drives upcycle actions. The fashion industry contributes 10% of global greenhouse gas emissions, according to the United Nations Economic Commission for Europe. Upcycling, or making unwanted materials into new products, is an important solution that goes hand in hand with recycling and reuse.
In China’s big cities such as Beijing and Shanghai, the trend is beginning to make an impact. Retopia, a sustainable lifestyle platform backed by student designer incubator Labelhood Youtopia, hosted a pop-up in a shopping centre in Shanghai to sell secondhand or upcycled clothes—70% of over 1,000 items were sold, according to the platform.
Haiyan Zhong, co-founder of Another Aura, which helped Fang find a new life for her old jacket, explains how her startup fits into the wider sustainability fashion context in China. “One part of it is to use natural, organic or biodegradable materials in making the clothes,” she says. “The other part is how to deal with the clothes and the materials they’re made from in their afterlife.”
Customers like Fang can help to influence the next generation. She is happy to see how her upcycle mindset rubs off on her 16-year-old daughter. “My daughter was very impressed with the final products from Another Aura. I hope she can be conscious of her purchases as well and adopt the same habit in the future.”
