1 . In 2022, campaign group Fashion Revolution Chelsea dye a garden for its Chelsea Flower Show presentation. An ancient craft, natural dyeing is a practice whose time has come again, with hand tie-dyed fashion also making a comeback in recent years.
The revival has been encouraged by Covid lockdowns, “which allowed people to explore the craft at home, says natural-dyeing enthusiast and teacher Susan Dye. It’s unlikely, though, that the practice would have caught on in quite the same way if not for a continually growing discomfort about fashion’s heavy footprint. From carbon emissions to animal cruelty, fashion is under considerable inspection. “Put it this way, 97% of dyes used in the industry are petrochemically (石油化学产品) based,” says sustainable fashion consultant Jackie Andrews, who helped advise the UN Ethical Fashion Initiative. We’ve got net zero targets which mean we’re going to have to remove all those petrochemicals from the manufacturing cycle.
Fashion is a huge polluter. According to the UN Environment Program, the industry is responsible for up to one-fifth of all industrial water pollution—due to the fact that most clothes today are produced in poorer countries where regulation is weak and enforcement weaker. Waste water is dumped directly into rivers and streams, poisoning the land as well as the water sources of people and animals who rely on them.
It’s easy to see why someone who cares about people, planet and animals, as well as clothes, might turn to natural plant dyeing. From the beauty of the raw materials—often wild plants-to the property of only bonding with natural fiber like cotton and linen (亚麻布) from the minor footprint of recycling old clothing that has grayed or faded over time to the vibrant and long-lasting dyeing results, plant dyeing feels like a quiet act of rebellion. This is why, while beginners start with simply changing their clothes’ color, new worlds open. Many of today’s natural dyers grow their own dye plants, run local community workshops, and advocate for change in industrialized fashion systems and beyond.

2 . Are you a tea drinker? If so, you’re not alone. Every day around the world millions of cups of this popular brew are drunk, and it’s been that way for thousands of years. The oldest discovered tea is from the Han Dynasty, dating from 206BC to 220AD. But it’s thought that the tea trend really took off during the Tang Dynasty in the 8th Century, when it became China’s national drink. Now, Turkey, the Republic of Ireland and the UK are believed to be the biggest tea—drinking nations, per capita.
Tea is consumed in many ways-slurped, sipped or glugged. It can be poured from pots, infused or brewed in the cup using tea bags—and it’s this latter process that is causing concern. Research last year found some premium tea bags might be leaving billions of microscopic plastic particles in the cup. Scientists from McGill University in Montreal found that some ‘plastic’ tea bags shed high levels of micro plastics into water. However, The World Health Organization says such particles in drinking water do not appear to pose a risk.
Most tea bags are made from paper, with a small amount of plastic used to seal them shut— made from oil. This has led to debate about whether they can be recycled, but many are still composted. However, gardener Mike Armitage has told the BBC that the plastic contained in the soil could be washed into streams and rivers and ultimately out to sea.
Unilever, the owners of the tea brand PG Tips, said their tea bags are made with a small amount of plastic—used to seal them—and that they are suitable for composting. And the brand Yorkshire Tea said their bags do contain 25% polypropylene, but they were “actively developing plant—based and biodegradable alternatives”.
While tea bag manufacturers might be doing their bit to reduce plastic pollution, it could be a good time to switch your favourite beverage to coffee, or if that isn’t your cup of tea then try using loose-leaf tea, which can have a better flavour.

3 . Two thirds of the ice in the glaciers (冰川) of the Alps is doomed! These glaciers will melt by the end of the century as global temperatures rise, according to a recent study.
Scientists claim that half the ice held in some 4,000 Alpine glaciers will disappear by 2050 due to global warming through the effect of past emissions. After that, even if carbon emissions drop to zero, two-thirds of the ice will still have melted by 2100. If emissions continue to rise at the current rate, the ice tongues will have all but disappeared from Alpine valleys by the end of the century. The most pessimistic prediction tells us that the Alps will be mostly ice-free by 2100. Only isolated ice patches would remain at high altitudes, representing five per cent, at most, of the ice volume seen today.
The researchers warn that the loss of these glaciers will mean much less water is available for farming and hydroelectricity, especially during droughts. It would also affect nature and tourism.
In February, a study found that a third of the huge ice fields in Asia’s towering mountain chains were also under threat for the same reasons. This will lead to serious consequences for almost two billion people who live downstream. Glaciers along the Hindu Kush and Himalayan range are at higher, colder altitudes. If global carbon emissions are not cut, however, two-thirds of their ice could be gone by 2100.
The latest research combined computer models with real-world data to forecast the fate of the glaciers. It used 2017 as its starting point. Unlike previous work, these models included how the glaciers move down the mountains. Applying this approach to other glaciated mountain chains could improve ice loss forecasts there.
Cutting the emissions from fossil-fuel burning, deforestation and other polluting activities is the biggest factor in minimizing the melting of the ice. The future of these glaciers is indeed at risk, but there is still a possibility of limiting their disappearance.

4 . Sprite has been recognized for decades by its green cans and bottles, but it is retiring its green plastic bottles after more than 60 years.
Starting Aug. 1, the Coca-Cola Co., which produces Sprite, will package the lemon-lime drink in clear plastic bottles in North America, the company announced Wednesday. Sprite’s current plastic contains green polyethylene terephthalate(PET)(聚对苯二甲酸乙二醇酯), an additive(添加剂) that can’t be recycled into new bottles, a key choice for the company as it looks to reduce plastic waste.
“When recycled, clear PET Sprite bottles can be remade into bottles, helping drive a circular economy for plastic.” Julian Ochoa, CEO of R3CYCLE, a plastic group helping Coca-Cola improve its recycling, said in a statement.
Customers will also notice a revised logo and packaging design on the Sprite bottles that aims to provide a more “consistent look around the world,” the company said. The well-known green color will still be used on Sprite labels. Other beverages that use green bottles in Coke’s portfolio(系列产品), including Fresca. Seagram’s and Mello Yello, will also be replaced with clear containers in the coming months.
Coca-Cola reported higher-than-expected second-quarter earnings Tuesday, citing strong demand, and lifted its revenue forecast for the full year.
The beverage giant has often been criticized for contributing to environmentally damaging plastic waste. In 2020, the company was named as the world’s No. 1 plastic polluter by the environmental firm Break Free From Plastic. Its logos and branding were found on 13, 834 pieces of discarded plastic in 51 countries, often in public spaces such as parks and beaches.

| D．Besides turning off the lights, people get involved in other events. |
| E．It pushes them to take urgent measures by making changes to policies. |
| F．That is, they switch off all unnecessary lights at the same time for one hour. |
| G．The plus invites people to continue their action even after Earth Hour is finished. |
6 . There is a kind of climate pollution that we can’t see clearly. It isn’t in our rivers, lands or skies, it is in our minds. When climate disinformation goes unchecked, it spreads like wildfire, undermining the existence of climate change and the need for urgent action.
Like the biosphere that sustains us, the health of our information ecosystems is vital to our survival. As an artist, I feel a responsibility to create new ways of seeing the disinformation that has come to define the age of fake news.
Social media sites are honed to grab our attention. Using sophisticated algorithms, the corporations behind them decide what billions of people see around the world, dictated by what keeps you hooked, but also by what the companies paying social media sites choose to put in front of you.
Powerful corporate actors deploy clever influence campaigns via ads targeted at specific users based on what social media firms know about those people. Major oil and gas companies have spent billions of dollars over the years persuading consumers about their green proofs, when only 1 per cent of their expenditure in 2019 was on renewable energy. This is known as corporate greenwashing. Still, fossil fuel firms maintain that their climate policies are “responsible” and “in line with the science”.
To expose the scale of corporate greenwashing online, I was part of a team that recently launched Eco-Bot.Net. Co-created with artist Rob “3D” Del Naja of the band Massive Attack and Dale Vince, a green entrepreneur, Eco-Bot. Net’s AI-powered website ran throughout the COP26 climate summit, exposing climate change misinformation by releasing a series of data drops for heavily polluting sectors, including energy, agribusiness and aviation.
Academic definitions of climate disinformation and greenwashing were used to unearth posts across Facebook, Instagram and Twitter and visualize them on our website. Eco-Bot.Net then flagged greenwashing ads and posts on the original social media site with a public health warning.
By digging into our data, journalists have already revealed that companies are targeting specific demographics in order to influence public perceptions about climate change – and even alter government policy.
One data drop focused on the 100 biggest fossil fuel producers, companies that have been the source of 71 per cent of global carbon emissions. It found that 16 of these companies ran 1705 greenwashing and climate misinformation ads globally on Facebook and Instagram this year. In total, they spent more than £4 million creating influence campaigns that generated up to 155 million impressions.
Social media companies could end most of the harms from climate disinformation on their platforms if they wanted to. Flagging systems were swiftly introduced to warn users of posts containing disinformation about covid-19. The scientific consensus on human-caused global warming has been resolute for decades, so why can’t a similar flagging system be implemented for related disinformation?
It is true that Twitter and Facebook have both introduced climate science information hubs, but these are little more than PR exercises that fail to directly tackle climate disinformation on any kind of scale.
This epidemic of climate change disinformation on social media is eroding collective ideas of truth. In this post-truth age of disinformation, we hope that the public, the press and policy-makers will be able to use our data findings to see what is hidden by what we see online.
For the first time, we can witness the regional scale of corporate greenwashing. The era of climate denial and delay is largely over — except, as Eco-Bot.Net has revealed, on social media.

7 . Bioluminescence (生物发光) is a natural phenomenon wherein a chemical reaction within an organism’s body produces light. It can be found in many places in nature — fireflies, some mushrooms — but mostly in the deep sea.
Recently, Rambouillet, a small historic French town, has teamed up with a company called Glowee to turn the city into a full-scale bioluminescence laboratory. The goal is to change the way in which cities use light. The company uses marine (海的) bacteria harvested from the coast of France. It makes some of the town’s public light up in the cool blue of bioluminescence.
These bioluminescent bacteria are stored in a seawater filled tube, giving the bacteria room to float around and light up. The light provided by the bacteria is part of their natural metabolism, so producing the light requires no energy other than that which is needed to feed the organisms. This makes it much more environmentally friendly and sustainable than electric light, which consumes a huge amount of non-renewable energy.
“On the way to lighting up the world with bioluminescence, you have to feed the bacteria and add water as they grow. That’s not so easy. The phenomenon will be very temperature-dependent and I doubt that it will work in the winter. Also, bioluminescence is not very bright compared to electrical lighting, though they have improved the light intensity,” Carl Johnson, a professor from Vanderbilt University said.
One potential solution to these issues — and one that Glowee is looking into — is to remove the biological aspect of the whole process. Theoretically, luciferase (荧光素酶) can be removed from the bacteria and used to create light instead of the bacteria itself. Because luciferase is non-living, it doesn’t need to be fed. Creating new means of sustainable lighting is a way of being environmentally friendly without plunging the earth back into darkness.

8 . Chaudhary weaves (编织) together lengths of rope and grass collected from the nearby riverbank in her village, skillfully shaping the materials into a gift box while instructing a group of women to follow suit.
The ropes being used were once the lifeline for mountain climbers tackling Nepal’s mountains and were then cast away. Diverse measures to remove such discarded materials have rocketed since 2019, when the government launched Clean Mountain Campaign.Around 140,000 tons of waste were collected on Mt. Everest alone, which were handled accordingly, either securely buried or recycled.
Some waste is now finding fresh life, transformed by skilled hands like Chaudhary’s into items to sell, thanks to an initiative led by Acharya, an owner of a waste processing business and an advocate for sustainable waste management. She has been working with the cleaning campaign, aiming at mountains like Mt. Everest.
“Metal waste goes through the recycling process, but we weren’t capable of recycling these ropes and cooking gas cans,” Acharya says. It didn’t occur to her that the waste which couldn’t be recycled could be reused until she met Rai at an art exhibition and a solution emerged.
Rai, a businessman dealing in craftworks, helped connect Acharya with Chaudhary and her team of craftswomen in hopes of unlocking the economic value of the mountain waste. With flexible hours, the project gives the craftswomen an opportunity to earn money even as they maintain their household responsibilities.
“While this seems insignificant compared to waste in the mountains, it’s a start. We can’t supply sufficient raw material with waste sorting and cleaning processes taking plenty of time and money,” Acharya says, desperate to expand the program to involve more women and treat more waste. But progress has been slow. “We need investment to mechanize the cleaning and processing of waste in the initial phase to provide the crafting team with enough materials to meet their demand,” she adds.

9 . During the 20th century, an estimated 3 million great whales were hunted to provide humans with oil, meat and rose fertiliser. Roger Payne, a biologist and environmentalist, spurred (推动) a worldwide environmental conservation movement with his discovery that whales could sing.
This discovery was made in 1967 during his research trip to Bermuda (百慕大) when a navy engineer provided him with a recording of curious underwater sounds documented. Payne identified the tones as songs whales sing to one another and he was conscious from the start that whale song was to get the public interested in protecting an animal previously considered little more than a resource, curiosity or nuisance.
Payne saw the discovery of whale song as a chance to spur interest in saving the giant animals, who were disappearing from the planet. In 1970, Payne released the album Songs of the Humpback Whale. The record, a surprise hit, fueled a global movement to end the practice of commercial whale hunting and save the whales from extinction. It remains the bestselling environmental album in history.
The impact of the whale song discovery on the early environmental movement was immense. Many antiwar protesters of the day took on saving animals and the environment as a new cause. The humpback whale became the icon of a new environmental awareness. And the whales entered pop culture, no longer the fearsome beasts. In 1977, the whale calls were loaded on to the Voyager probes and sent into outer space.
Payne, graduating from Harvard University and Cornell University with a doctor’s degree, authored or co authored dozens of scientific papers, gave hundreds of lectures, made countless television programmes and films, and led 100 oceanic expeditions. Payne had started an ambitious new project: CETI, a combination of scientists using new technology to interpret what whales might be “saying”.

10 . Sri Nihal Tammana, age 13, of Edison, New Jersey, was named a winner of the 2022 Gloria Barron Prize for Young Heroes. The Barron Prize annually honors 25 outstanding young leaders who have made a significant positive impact on people, their communities, and the environment.
Nihal founded Recycle My Battery to promote and facilitate the recycling of used batteries. His nonprofit places free battery recycling bins(箱子)and educates young people and adults about battery recycling. In just three years he has built a team of more than 250 student volunteers across the globe who have recycled nearly 200,000 batteries and educated millions of people. Nihal learned at age 10 that 15 billion batteries are thrown away each year and that most end up in landfills(垃圾填埋地)where they pollute groundwater, harm the ecosystem, and can cause catastrophic fires. Inspired to tackle the problem, he began collecting used batteries from his community. He put them in free recycling bins at stores like Staples until he was told he was bringing too many and had to stop.
Undeterred, he reached out for help from Call2Recycle, the largest battery recycling nonprofit in North America. Call2Recycle agreed to assist and provided recycling bins for free, which were placed in schools, libraries, and other public places. Nihal’s organization now operates across the U.S. and is expanding to other countries including Canada, Switzerland, and India. “Earth gives us so much — oxygen, food, water — everything! So it’s important that we give something back when we can,” says Nihal.
The Barron Prize was founded in 2001 by author T. A. Barron. “Nothing is more inspiring than stories about heroic people who have truly made a difference to the world,” says T. A. Barron. “And we need our heroes today more than ever. Not celebrities, but heroes — people whose character can inspire us all. That is the purpose of the Barron Prize: to shine the spotlight on these amazing young people so that their stories will inspire others.”
