“This is your last chance,” warned Mrs Gillfeather. I broke out in a sweat and my hands started to shake. We both wanted to get to sleep, but before we could, I had to put a cannula(针管) in her arm.

    Before becoming a doctor I'd only a vague idea what a cannula was, coming from an hour spent with a plastic arm while at medical school. Once I became a doctor, however, I couldn't seem to get away from them.

    For those of you who are lucky enough to have never come into contact with one, they're tiny little tubes that are put into a vein(静脉)so that fluid or medicines can do directly into the blood. That's the theory. Unfortunately, the problem is that for them to work, you have to get them into the vein in the first place. This tends to be trickier than you'd imagine—and it's a job that tends to fall on the junior doctors.

    Mrs Gillfeather's veins were particularly elusive that evening. I'd been jabbing the needle in for at least 20 minutes.

    “Isn't there someone else who could do this?” she asked, for the fourth time. “Someone who knows what they're doing, perhaps,” she said under her breath, just loud enough for me to hear.

    Finally, I got it in. Mrs. Gillfeather and I both breathed a sigh of relief

    Just as I was about to leave the ward, the nurse called me over, “Max, there's another cannula to do on bed 16.”

    People have used pigeons to carry messages to one another for hundreds of years. In fact, pigeons were a common way to send messages right up through Would War II.

    In 1815, English troops were fighting Napoleon's forces in France, and the English were believed to be losing. A financial panic swept over London. Government bonds（债券）were offered at low prices. Few people noticed that Nathan Rothschild, an English banker, was snapping up these bonds when everyone else was trying to sell them. A few days later, London learned the truth: the Duke of Wellington had defeated Napoleon at the battle of Waterloo. The value of the bonds soared（暴涨）, and Rothschild became wealthy…all because his pigeons had brought him news of the victory before anyone else knew of it.

    Carrier pigeons were used by countries in both World War I and World War II. Not only were the birds often the fastest, most reliable way to send messages, they could also be used to reach soldiers far behind enemy lines, where radios and field telephone lines were useless. Since they could easily be released from airplanes or ships, every branch of the armed services used the birds.

    Carrying messages could be a dangerous job. Some pigeons performed with such bravery that they became famous and were even awarded medals. The most famous pigeon of all may have been Cher Ami. Stationed in France during World War I, he carried twelve important messages for American forces. On his last mission, though wounded, he carried a message that saved the lives of 194 American soldiers. For his amazing service, he was awarded the French “Croix de Guerre.”

    Today, modern communication methods can carry information from one place to another hundreds of times faster than a pigeon could do it. However, few people would argue with the fact that carrier pigeons — especially those that served in the military — have earned their place in history.

    It is not always a good thing to praise children because "empty" words may make them unhappy. Words such as "well done" may make them doubt their own abilities, a leading psychologist (心理学家) Stephen Grosz has warned. He says that words such as "you're so clever" or "you're such an artist" could also hinder their future development at school. He says that such empty praise causes children to be unhappy as they may say they can't live up to these expectations.

    Instead he advises parents and teachers to praise children less frequently and use words like "trying really hard," Mr. Grosz said, "Empty praise is as bad as thoughtless criticism (批评). People often pay no attention to children's feelings and thoughts." He also mentions research showing that children who are heavily praised probably perform worse at school.

    Some psychologists from Columbia University asked 128 pupils aged 10 and 11 to work out a number of math problems. Afterwards, some were told, "You did really well­—you're so clever." But the researchers told the other group, "You did really well­—you must have tried really hard." Both groups of children were then given more difficult questions and those who had been told they were clever did not do as well as the others.

    He says that when collecting his daughter from a school near their home in North London, he heard a teacher tell her, "You have drawn the most beautiful tree. Well done," Later, after she had done another drawing, the same teacher said, "Wow, you are really an artist." In his book, Mr. Grosz writes, "How could I explain to the teacher that I would prefer it if she did not praise my daughter?"

    As a parent of two children, I strongly agree with Mr. Grosz. I praise them when praising is proven right. I want them to know if I praise them, they have done something beyond my expectation, beyond what they are able to do.

    Darrell Blatchley, a marine biologist and environmentalist based in the Philippine city of Davao, received a call from the Philippines, Bureau of Fisheries and Aquatic Resources (渔业与水产资源局) early Friday morning reporting a death of a young whale.

    When the necropsy (尸检) was performed, Blatchley told NPR, he was not prepared for the amount of plastic they found in the whale's stomach. "It was full of plastic nothing but nonstop plastic." he said "It was filled to the point that its stomach was as hard as a baseball." That means that this animal has been suffering not for days or weeks but for months or even a year or more," Blatchley added.

    Blatchley is the founder and owner of the D'Bone Collector Museum, a natural history museum in Davao. In the coming days, the museum will display all the items found in the whale's system. Blatchley and his team work with the Bureau of Fisheries and Aquatic Resources and other organizations to assist in rescue and recovery of marine animals.

    "Within the last 10 years, we have recovered 61 whales and dolphins just within the Davao Gulf," he said. "Of them, 57 have died due to man whether they took plastic or fishing nets or other waste, or gotten caught in pollution — and four were pregnant."

    Blatchley said he hoped that the latest incident would launch the issue of plastic pollution in the Philippines and across the globe. "If we keep going this way, it will be more uncommon to see an animal die of natural causes than it is to see an animal die of plastic," he said.

Recycled, reused and renewable textiles（纺织品）only go so far in solving the fast-fashion crisis, writes Alexandra Carlton. The answer may lie in consumption.

Australia is the world's second-largest consumer of clothing, generating 800,000 tonnes of textile waste yearly. Individuals consume about 27 kilograms of new clothes annually and cast 23 kilograms of waste. Globally, the situation is even more severe, with an estimated 92million tonnes of clothing waste produced each year. This equates to a truckload of clothes entering landfills every second.

If you want to stop our unwanted clothes from jamming the planet, you'd assume that reusing and recycling would lead the discussion. However, full clothes recycling—breaking clothes down to their base fibres to create new ones—is no simple task. Clothes consist of various fibres, fasteners, and decorations that traditionally require painstaking manual（手工的）separation. Yet, innovation is underway, such as the Swedish large-scale sorting facility Siptex, where textiles can be sorted by color and material using infrared（红外线）technology.

Brands like Adelaide's Autark focus on minimizing output. "I keep my collections tightly designed and production numbers slim," says designer Sophia McMahon. Sometimes this means she doesn't have the exact clothes someone wants in store, but customers are patient while she makes items to order because they understand her brand's essence.

Startups like AirRobe are giving clothes a second life and could be part of the solution. The clothing resale market is currently worth 49 billion and is expected to reach 103 billion by 2025. AirRobe lets customers add new purchases to their digital wardrobe so they can be resold later without uploading photos or descriptions. "The ‘re-economy'—the reuse and recycle market sector—will be a real opportunity for us," says Erica Berchtold, CEO of The Iconic.

Researchers Samantha Sharpe and Taylor Brydges from the University of Technology Sydney advocate a widespread shift among consumers towards buying fewer, higher-quality clothes besides these innovations.
