1 . That artificial food dyes (染料) are unhealthy is not news. Some are known to cause hyperactivity (多动症) in some children, affecting their ability to learn. But regulatory agencies (监管机构) around the world don’t necessarily agree on which food dyes are a problem, or why. That may soon change. A 2021 peer-reviewed report by California’s Office of Environmental Health Hazard Assessment concluded that artificial food dyes “cause or worsen neurobehavioral (神经行为的) problems in some children” and that the current levels that are regarded safe for consumption by the federal government are too high.
California is now considering requiring warning labels on food products and dietary supplements containing the seven most commonly used artificial dyes. The warning label requirement would put California on par with the European Union, which since 2010 has required food products containing certain artificial food dyes to carry warning labels about their negative effect on activity and attention in children.
Artificial dyes are used in foods for one reason: to make products look prettier. Bright colors make candies appealing, especially to kids. But dyes are also in chocolate cake mixes, salad dressings and other products that don’t seem to cry out for a color boost.
In Europe, it was the 2010 label lawmaking that triggered (引发) companies’ decisions to reformulate. “If you’re a company, you do not want to put a warning label on your product.” says Lefferts, an environmental health consultant. Warning labels are why European Starburst Fruit Chews are now colored with natural products, not the artificial dyes that brighten their North American counterparts (同类商品).
Given that artificial food dyes are used far more than needed, we need to be more cautious. After all, we don’t dye fresh fruits and vegetables, but we do dye candy and sprinkles, points out Joe Schwarcz, a chemistry professor at McGill University in Montreal. “The foods in which you find food dyes are foods that are poor in nutrition,” he says. “If you limit foods that contain food dyes, you automatically make your diet better.”

4 . A shocking 53.6 million metric tons of electronic waste was discarded last year, a new UN-backed report has revealed. The report shows that e-waste is up by 21% from five years ago. This isn’t surprising, considering how many more people are adopting new technology and updating devices regularly to have the latest versions, but the report also shows that national collection and recycling strategies are nowhere close to matching consumption rates.
E-waste contains materials including copper (铜), iron, gold and silver, which the report gives a conservative value of $ 57 billion. But most are thrown away or burned rather than being collected for recycling. Precious metals in waste are estimated to be worth $ 14 billion, but only $ 4 billion-worth is recovered at the moment.
While the number of countries with national e-waste policies has grown from 61 to 78 since 2014, there is little encouragement to obey and a mere 17% of collected items are recycled. If recycling does occur, it’s often under dangerous conditions, such as burning circuit boards to recover copper, which “releases highly poisonous metals” and harms the health of workers.
The report found that Asia has the highest amounts of waste overall, producing 24.9 million metric tons (MMT), followed by Europe at 12 MMT, Africa at 2.9 MMT, and Oceania at 0.7 MMT.
But whose responsibility is it? Are governments in charge of setting up collection and recycling points, or should companies be responsible for recycling the goods they produce? It goes both ways. Companies do need to be held accountable by government regulations and have incentives to design products that are easily repaired. At the same time, governments need to make it easy for citizens to access collection points and deal with their broken electronics in a convenient way. Otherwise, they may turn to the easiest option — the landfill.

7 . The Stanford marshmallow (棉花糖) test was originally conducted by psychologist Walter Mischel in the late 1960s. Children aged four to six at a nursery school were placed in a room. A single sugary treat, selected by the child, was placed on a table. Each child was told if they waited for 15 minutes before eating the treat, they would be given a second treat. Then they were left alone in the room. Follow-up studies with the children later in life showed a connection between an ability to wait long enough to obtain a second treat and various forms of success.
As adults we face a version of the marshmallow test every day. We’re not tempted by sugary treats, but by our computers, phones, and tablets — all the devices that connect us to the global delivery system for various types of information that do to us what marshmallows do to preschoolers.
We are tempted by sugary treats because our ancestors lived in a calorie-poor world, and our brains developed a response mechanism to these treats that reflected their value — a feeling of reward and satisfaction. But as we’ve reshaped the world around us, dramatically reducing the cost and effort involved in obtaining calories, we still have the same brains we had thousands of years ago, and this mismatch is at the heart of why so many of us struggle to resist tempting foods that we know we shouldn’t eat.
A similar process is at work in our response to information. Our formative environment as a species was information-poor, so our brains developed a mechanism that prized new information. But global connectivity has greatly changed our information environment. We are now ceaselessly bombarded (轰炸) with new information. Therefore, just as we need to be more thoughtful about our caloric consumption, we also need to be more thoughtful about our information consumption, resisting the temptation of the mental “junk food” in order to manage our time most effectively.

8 . There was a time when a trip to the supermarket in the United States often ended with a seemingly simple question from the cashier, “Paper or plastic?” Well, which type of bag would you choose?
While both types of bags have some influence on the environment, it has long been supposed that paper bags are better. They are made from a renewable source, are broken down easily, burn without giving off thick smoke and can be recycled. However, the producing process behind paper bags uses more energy than that of plastic ones. How can this be true?
Studies show that paper bag production requires four times as much energy as plastic bag production. And the amount of water used to make them is twenty times larger. Besides, the influence on forests is very serious. It takes about fourteen million trees to produce ten billion paper bags, which happen to be the number of bags used in the United States yearly. In terms of recycling, the idea that paper bags are more environment-friendly than plastic ones can be quickly discarded. Research shows it requires about 98% less energy to recycle plastic than it does to recycle paper.
Even though paper bags might be more harmful than plastic ones, plastic still seems to be considered as the more harmful of the two by governments. In Ireland, for example, a tax has been introduced to discourage the use of plastic bags. People have to pay 22 cents for every plastic bag, and as a result, their use has dropped quickly.
There’s no doubt that it makes more sense to reuse these bags. However, we don’t seem to be doing that at present. That may be because they fall apart quickly. If so, cloth bags are a better choice, but still, their production also has a bad influence on the environment. So what to do? How should we answer the question of “Paper or plastic?” It seems that we first need to ask ourselves one more general question: “What can I do to help the environment?”

9 . From self-driving cars to carebots (care+ robots) for elderly people, rapid development in technology has long represented a possible threat to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2035 as artificial intelligence (AI) continues to change businesses.
“The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew, Director of Workplace Strategy for CBRE Asia-Pacific. A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.
The report is based on interviews with 200 experts, business leaders and young people from Asia-Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates. But the report states, “Losing occupations does not necessarily mean losing jobs—just changing what people do.” Growth in new jobs could occur as much, according to the research. “The growth of 20- to 40-person companies that have the speed and technological know-how will directly challenge big companies,” it states.
Another study by Pew Research Centre found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured “a future in which robots do not take the place of more jobs than they create.”
“Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people, there were billions of jobs. There is no shortage of things that need to be done and that will not change,” Microsoft’s Jonathan Grudin told researchers.

10 . Every 40 days a language dies. This “catastrophic” loss is being intensified by the climate crisis, according to linguists. If nothing is done, conservative estimates suggest that half of all the 7,000 languages currently spoken will be extinct by the end of the century.
Speakers of minority languages have experienced a long history of persecution (迫害), with the result that by the 1920s half of all indigenous (土著的) languages in Australia, the US, South Africa and Argentina were extinct. The climate crisis is now considered the “final nail in the coffin” for many indigenous languages and the knowledge they represent.
“Languages are already endangered,” says Anastasia Rachel, director of the Strathy language unit at Queen’s University in Kingston, Ontario. Huge factors are globalization and migration, as communities move to regions where their language is not spoken or valued, according to Rachel. “It seems particularly cruel,” she says, “that most of the world’s languages are in parts of the world that are growing unpleasant to people.” Vanuatu, a South Pacific island nation measuring 12, 189 km2, has 110 languages, the highest density of languages on the planet. It is also one of the countries most at risk of sea level rise. “Marty small language communities are on islands and coastlines easily subject to hurricanes and sea level rise,” she says. Others live on lands where rising temperature threatens traditional farming and fishing practices, leading to migration.
In response to the crisis, the UN launched the International Decade of Indigenous Languages (IDIL) in 2022. Promoting and conserving languages of indigenous communities is “not only important for them, but for all humanity”, said Csaba Korosi, the UN general assembly president, urging countries to allow access to education in indigenous languages.
