2 . 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.

4 . Artificial intelligence (AI) has been increasingly good at fooling people. A series of photos showing former US president Donald Trump being aggressively arrested by police have caught people’s attention. They were fake but very convincing.

Created by the AI program Midjourney, the photos were highly realistic, from the characters’ movements to the surroundings. However, many details can give away the fact that they are made by AI. The Washington Post’s technology writer Shira Ovide shared her tips. The main idea is to spot the problems-anything that would look strange in a photo.

AI software has a history of generating human hands incorrectly. It sometimes can create hands with more than five fingers. This is because AI isn’t sure what a “hand” exactly is, according to Popular Science. The data AI uses to learn often show hands and fingers in various gestures, which can be very confusing for AI.

AI-generated images also usually contain details that are against reality. To spot this, focus on items like accessories. For example, people in an image may be missing earrings or one part of their sunglasses. If there’s text in an image, such as a newspaper or poster, it’s usually garbled (篡改), even though the text may look realistic from a distance.

Another thing AI is terrible at handling is the background. If there’s a crowd in the image, people’s faces in the background are usually blurry — or they don’t have faces at all!

The development of AI-generated art also raises alarm bells about how these fake images could be used to spread misinformation. “I think misinformation is going to hit an all-time high,” Jamie Cohen, a digital culture and AI expert in the US, told New York Post. Generating an AI artwork is to “create reality”, Cohen argued, adding that, being able to tell whether the work is real or not requires high media literacy (素养) skills. “The world may not be ready for how realistic the images have become,” Shane Kittelson, a US researcher, told The Washington Post.

5 . A Dutch city will become the first in the world to ban meat adverts from public spaces in an effort to reduce consumption and greenhouse gas emissions (排放). Haarlem, which lies to the west of Amsterdam and has a population of 160,000, will pass the prohibition from 2024 after meat was added to a list of products thought to contribute to the climate crisis.

Adverts will not be allowed on Haarlem’s buses, shelters and screens in public spaces, causing complaints from the meat sector that the city government is “going too far in telling people what’s best for them”.

Recent studies suggest global food production is responsible for one-third of all planet-heating emissions, with the use of animals for meat accounting for twice the pollution of producing plant-based foods. Forests that absorb carbon dioxide are cut down for the grazing (放牧) of animals while fertilizers used for growing their feed are rich in nitrogen (氮), which can contribute to air and water pollution and climate change. Livestock also produces large quantities of methane (甲烷), a powerful greenhouse gas.

Ziggy Klazes, a councilor from the GroenLinks party, who drafted (起草) the law banning meat advertising, said she had not known the city would be the world’s first to enforce (执行) such a policy when she proposed it. She told the Haarlem 105 radio channel, “We are not about what people are baking and roasting in their own kitchen; if people wanted to continue eating meat, fine… Of course, there are a lot of people who find the decision unacceptable, but there are also a lot of people who think it’s fine.”

The ban also covers holiday flights, fossil fuels and cars that run on fossil fuels. The ban is delayed until 2024 due to existing contracts with companies that sell the products.

Research suggests that to meet the EU target of net zero emissions by 2050, meat consumption must be reduced to 24kg per person per year, compared with the current average of 82kg or 75.8kg in the Netherlands, which is the EU’s biggest meat exporter.

6 . A promotion (促销活动) offering 98 yuan domestic plane tickets is being advertised by Chinese online travel platform LY.COM. While such a low price sounds amazing, there is just one catch: the purchaser is not told where the flight is heading, nor when it will take off.

The promotion has become a trending topic on Chinese social media as some people have been attempting to book them ahead of the upcoming May Day holiday. Labeled as a “destination blind box” on the site, tickets are purchased through a rather simple booking procedure, in which passengers provide their travel information, select a departure airport and then pay their 98 yuan. If the randomly chosen date and destination are unsuitable, users may ask for a refund, but once they “lock in” their tickets，there is no going back.

“Destination blind box” is now a hot topic on China’s online platforms. “I believe young people are a big target demographic (特定年龄段人口) for this promotion, because they not only enjoy the thrill of the unknown, but also like to show off their lives through these types of commercial activities. Like this one for instance, it doesn’t matter if they finally go or not. Booking a ticket and posting about it on social media can still suggest that one has adventurous and life-loving qualities,” said Fan, a marketing expert who has worked with civil aviation clients.

Many people not only shared the screenshots of tickets they drew, some even came up with a tutorial to teach the booking procedure under the free cancelling policy. However, some others claimed it is too rare to draw a ticket that is ideal. “If it wants to be a profitable activity, the release of the tickets must have been planned ahead and is not as random as it seems. It will not have popular airlines. The marketing campaign may also be aimed at the fast sale of some tickets from less popular airlines that were originally not that expensive. If they sell a large quantity of tickets, the company may still earn a profit even though the price is 98 yuan,” an expert in tourism suggested.

9 . One form of social prejudice (偏见) against older people is the belief that they cannot understand or use modern technology. Activities like playing computer games, going on the Net and downloading MP3s are only for the youngsters. Isn’t it unfair that older people enjoying a computer game should be frowned upon (反对) by their children and grandchildren?

Nowadays older people have more control over their lives and they play a full part in society. Moreover, better health care has let more people in their sixties and seventies feeling fit and active after retirement. Mental activity, as well as physical exercise, can contribute to better health. Playing computer games is a very effective way of exercising the brain. So that’s why grey gamers are often seen now.

When personal computers were first introduced, most older people didn’t believe they would ever get familiar with them. Now computers have been around for a few generations and retired people have gradually become more relaxed about using them for fun. Gamers over 65 prefer playing puzzle games and card games. Kate Stevens, aged 72, says, “I find it very relaxing. It’s not very demanding, but you still need to concentrate.”

Another development that has favored “grey games” is a change in the type of video games available on the market. There’s a greater variety of games to choose from, including more intellectual and complex strategy and simulation (模拟) games. For example, Internet Chess and Train Simulator are among the most popular of these. Train Simulator is based on real — world rail activities. Players can choose from a variety of challengers, such as keeping to a strict timetable and using helper engines during a winter storm.

Some people argue that “grey gamers” simply don’t have the skills required for computer games, and that teenagers are better. This couldn’t be further from the truth. Most computer games require the kind of analytical thinking that improves with practice, which means that the “grey gamers” may well be far better than the young. In games where speed is the main consideration, older people would be at a disadvantage because they may have slower reaction. time. On the other hand, “grey gamers” have a preference for slower — paced, mind challenging games.
