I was eight years old and wasn’t aware of all the arrangements being made for our journey as a family to London in 1950. My mother was in great pain and wished to visit specialists in London. My father reluctantly had to sell our property in Queensland. The day before we boarded the ship, Father unwillingly said goodbye to his five-year-old cattle dog, Spider, who was loved by us all. Father’s friend Sandy was to be his guardian while we were overseas, as he had been getting to know Spider for many weeks.
Six weeks later, an airletter arrived from Sandy, giving my father the news that Spider had run away just two weeks after we had sailed. Sandy had advertised constantly on ABC and other regional newspapers. Despite many “sightings”, the dog was never found. It seems Spider just kept running and searching for us. As he was cattle dog, my father thought he would shoe or dingo-trapped, because of his appearance. But our family thought that Father held a secrets hope that Spider was still alive.
We sailed back to Australia two years later and re-established our home. My father immediately began his own search for Spider. One cold winter’s Saturday morning eight months after our return, my father had a call from an elderly lady living on her own on the outskirts of the town. As she told my father on the telephone, it was “just glimpses of a dingo-type dog in the shadows” of her disused tennis court. That was enough for my father to interrupt my homework.
We set off in his blue and black Jensen car which he had brought back from England. It was hardly the right vehicle for the rough roads we travelled that day. Five and a half hours later, we found the run-down old property. Sadly, she told my father that the “dingo dog” hadn’t been around for a few days. My father had a strange look in his eye. He put two fingers to his lips and did his special whistle for Spider.

2 . People have come to understand the enormous impacts-beneficial as well as harmful- plastics have on human lives and the environment. As polymer (聚合物) scientists committed to inventing sustainable solutions for real-world problems, we set out to tackle the issue of plastic waste by rethinking the way polymers are designed so we could make plastics with recyclability built right in.
Everyday items including milk jug, grocery bags, and takeout containers are made from a class of polymers called polyolefins. These plastics are really durable (耐用的) because the chemical bonds in those polymers are extremely stable. In a world set up for disposable (一次性的) items, durability is no longer a design feature but rather a design drawback. Imagine if half the plastics used today were recyclable through twice as many processes as they are now. Also conventional recycling requires careful sorting of all the collected materials, which can be challenging with so many different plastics. For example, separating paper from metal doesn’t require complex technology, but sorting a container from a milk jug of a different polyolefin is difficult to do without the occasional mistake.
In a study published in Science in October 2023, we described a series of polymers with only two building blocks-one soft polymer and one hard polymer-that behave like polyolefins but could be chemically recycled. Connecting two different polymers multiple times until they form a single, long molecule (分子) creates what’s called a multiblock polymer. By changing how much of each polymer type goes into the multiblock polymer, our team produced a wide range of materials with properties that covered all polyolefin types.
Using the same strategy but by adding hydrogen, we could disconnect the polymers back into their building blocks and easily separate them to use again. When we made new polymers out of these recycled plastics, they performed just as well as the original materials even after several rounds of chemical recycling. So we were able to create materials with similar properties of the plastics the world relies on. We believe this work is a step toward more sustainable plastics.

Swim Buddies
I leaned (倚靠) over the side of the beat and stared at the clear blue water. This was my last chance, I thought. “I hope you find a green turtle (乌龟) today, Alexa, and realize your dream of swimming with it.” Dad said, as if reading my thought. “Me, too,” my brother, Jonah, said. “I want to see one, too!”
I lifted my head up, turned toward Jonah, and glared. Why, why, why did he always insist on following me everywhere, doing everything I did? Make your own friends. I wanted to scream at him. Find your own green sea turtle! But I said nothing. Ever since Jonah was a little kid and they discovered he acted so differently because he had autism (自闭症), I had been trained to show understanding for him. Trained to put up with a lot, including his shouts at the top of his lungs.
“We’ll stop here, and if we are lucky enough to see turtles.” Father said, “remember not to get too close, or they will be scared away. Do the ‘dead man’s float’ and wait. If they’re curious enough, they’ll cheek you out.”
Jonah said — too loudly, of course, so everyone on the boat could hear him —“That turtle sounds just like me. It wants to be friends but doesn’t know how, like me. I really, really, really want to see one, Dad.”
Putting the mouthpiece into my mouth, I dived into the water. I swam in a different direction and searched the seafloor. Suddenly, I saw a huge green turtle chewing on the seaweed. Excited as I was, I did the dead man’s float, lying as still as possible. “Come on, buddy (伙伴).” I said to myself, “Come swim with me!”
As I watched than lonely turtle, I couldn’t help bust think of Jonah’s words about friends — Jonah didn’t have friends. He functioned well enough to be in a regular class, but he was still strange enough that the other kids stayed away from him. This turtle might be the only one we could find today. And I knew that Jonah had got his heart set on seeing one, just like I did. Even though Jonah made my life really hard. I understood how he felt. I swam to Jonah.

4 . It’s reported that about 20 percent of the Amazon rainforest has disappeared during the past 50 years. Deforestation is not only threatening the millions of unique plant and animal species native to the Amazon River area, it’s affecting humans worldwide. When it comes to the protection of the Amazon, it’s hard for many people to relate because they don’t feel connected to the area. There are actually a lot of direct connections, no matter how far away we are.
A connection that affects everyone on the planet is climate (气候) change. Planting new trees in the forest is basically a way of removing CO2 from the air. Rain forests have a carbon (碳) reduction nearly equal to half of what is in the air. About half of that is in the Amazon. Another case in point is a big snake called the bushmaster that lives in the Amazon. Today, millions of people use medicines made from its venom (毒液) to treat high blood pressure. So they have longer, fuller, and more productive lives.
In the 1960s, there was only one highway in the entire Amazon. That’s an area as large as the continental United States with one highway and three million people. Today, there are between 30 million to 40 million people, countless roads, and about 20 percent forests have been cut down. But on the plus side, 50 years ago there were only two national parks and a national forest and a reserve in Brazil. Today, more than 50 percent of the Amazon is under some form of protection.
“There’s been a lot of damage done and forest lost, but nothing is gone until it’s gone”, noted National Geographic explorer Dr. Thomas Lovejoy. “We want to see more shared planning between the departments of transportation, energy, agriculture, and the other industries in the area. We think Amazon cities can have higher quality of life and keep people in existing cities so there’s less reason to deforest.”

| C．Protecting the species. | D．Polluting the rivers. |
| A．The increase of extreme weather. | B．The removal of CO2. |

5 . To reduce the carbon emissions from passenger jets and long-haul trucks, a vast volume of soy-based renewable fuel will be needed. To produce it, American farmers could ruin existing cornfields to clear space, plant millions of additional acres of soybeans and shut down all soybean exports. Researchers at startups and biotech giants alike have found ways to create a new kind of soybeans through genetic recombination that generates more oil.
One of the startups, ZeaKal Inc., funded in part by seed giant Corteva Inc., plans to introduce its first batch of high-oil seeds for commercial planting in 2024. Scientists have tricked the plant into sustaining photosynthesis for longer with genetic recombination, ultimately producing more oil as well as more protein.
Companies are racing to build more capacity to process soy, a critical component for expanding green fuel supplies. Tax credits make companies in the transportation industry switch to fuel with lower carbon emission. S&P Global sees domestic demand for renewable biofuel reaching 4 billion gallons in 2030, up from around 2.7 billion this year. It projects that the use of sustainable aviation fuel will total 1.7 billion gallons annually by the end of the decade, compared with just 182 million gallons a year now.
Despite the bullish predictions, the soy-based transportation fuel market is still a drop in the bucket for the fuel industry. And even if the new breed of high-oil seeds takes off, widespread adoption will take time. Farmers may be reluctant to become early adopters of a technology that hasn’t yet proven its benefits, especially if the oil content comes at the expense of existing genetic recombinations that improve disease or pest resistance.
Chicken producer Perdue Farms Inc. has signed a deal with Zeakal, agreeing to pay farmers a higher price for harvested supplies of the new variety, which is good for chicken feed because of its higher protein levels. If large oil companies follow suit, the soybean market might never look the same. “We could have an opportunity for the oil component of soybeans to actually become more important in some markets than the protein aspect,” says Mike Dillon, vice president of ZeaKal, “That’s a very dramatic shift.”

6 . Whenever I order food for delivery, I play a little game to guess how many sets of tableware(餐具)the restaurant will provide with my meal. Sometimes restaurants will throw in two, three or four sets for just one order. But I rarely need any tableware at all, and the waste goes into the trash or collects dust in a kitchen drawer.
Researchers working with Chinese technology group Alibaba tried a simple approach to this problem. Instead of just wastefully doling out tableware, the company required food-delivery customers in some cities in China to pick how many sets of tableware they wanted to receive.The default (默认设置)was set at zero. The result, published today in the journal Science, was a 638% increase in the share of no-tableware orders. If applied across China, researchers found, the approach would save nearly 22 billion sets of plastic tableware. The study doesn’t cover carbon emissions, but it’s safe to say that the impact would be significant. It struck me as a useful reminder of the many low-hanging fruits across the economy that can cut waste, and emissions.
Nudging its customers cost Alibaba nothing more than a few hours of software engineering time and the impact it brought was immense. The concept of nudging comes from the field of behavioral economics known as nudge theory. It suggests that a slight action can encourage good human behavior without the need for policies that limit choice or economic punishment that raises the cost of bad behavior. To nudge customers to eat better, for example, a restaurant might organize its menu by listing healthy options first and bury unhealthy ones at the bottom. More recently, some big companies like Google have also begun to use nudges to advance climate objectives.
Behavioral economics broadly, and nudges more specifically, aren’t without controversy. Some might think it assigns consumers responsibility for addressing environmental challenges. But there is another way to look at it. In the absence of necessary policy—and policy is needed一companies can help encourage a widespread shift of consumer behavior.
And all of that behavioral change can add up. The International Energy Agency found in 2021 that small behavioral changes in energy consumption such as walking instead of driving and adjusting the thermostat could in total shave off 4% of global emissions. The more that companies can do to facilitate such changes, the better.
1. What did Alibaba do with tableware waste?| A．It stopped restaurants from handing out tableware. |

7 . When most kids go to the beach, they’re too focused on making sandcastles and splashing around to notice litter, but several years ago, for 7-year-old Cash Daniels, noticing a plastic straw sparked a lifelong passion for saving the planet.
Cash, who is now known as the “conservation kid”, has always loved nature. He grew up fishing along the Chattanooga River, after all! But once he learned that 80 percent of all trash from land and rivers ends up in the ocean, he couldn’t sit back.
He started with cleanups along the river, something that quickly went from a family affair to a community effort with volunteers and neighbors. In 2019, Cash, together with a Canadian conservationist, Ella Galaski-Rossen, started a nonprofit called the Cleanup Kids. Despite living in different countries, they managed to create educational videos on their YouTube channel. “We hope to be a really big nonprofit that eliminates plastic in the U. S. and Canada,” Cash said. “We want to inform kids and adults in the landlocked states on how their actions are connected to the water and the ocean,” Cash said.
Cash was selected as one of America’s top 10 youth volunteers of 2021 by the Prudential Spirit of Community Awards. He also earned the title of National Honoree, where he received a$5,000 grant to go to a nonprofit of his choice, and he became the first person to win the Youth Conservationist Award two years in a row from the Tennessee Wildlife Federation.
“I want to travel the world, teach others, and help them feel connected to the ocean. Because if you are connected to the ocean-if you love it and what lives in it—you’ll want to protect it,” he said. “This is my fun, and it becomes more fun with every new discovery.”

8 . The most beloved bird in history may very well have been a 29-year-old pigeon by the name of Martha. It was the early 1900s, and Martha was at the height of her fame. Perched on her humble roost at the Cincinnati Zoo, she was an object of fascination to the thousands of visitors who lined up just to catch a glimpse. Martha may not have looked the part of an animal celebrity, but she was hardly average—in fact, she was the very definition of one of a kind. After the death of her companion George in 1910, Martha had become the world’s last-living passenger pigeon.
There was a time not long before when her kind accounted for more than a quarter of the birds in North America and may have been the most abundant bird species on the planet. Passenger pigeons used to travel at 60 miles an hour in flocks a mile wide and 300 miles long. Witnesses compared them to a train rumbling through a tunnel.
Ironically, the passenger pigeons’ very abundance may have spelled their doom. An agricultural pest and reliable source of protein, they became easy targets for hunters who killed them in the tens of thousands. In a matter of decades, a bird that once numbered in the billions was reduced to a few, and then, eventually, to one.
Martha, who’d grown up in captivity, had no offspring of her own. At 1 p.m. on September 1, 1914, Martha fell from her perch, never to rise again—one of the rare occasions in which historians could identify the exact moment of a species’ extinction.
Of course, the real tragedy was that the loss of the passenger pigeon was neither surprising nor unique. For as long as the Earth has sustained life, it has also seen the permanent disappearance of life forms, the dinosaurs being a particularly extreme example. But Martha’s high-profile death trained national attention on an alarming new trend. Close to a thousand animal species alone have died off in the last 500 years, and the trend is only getting worse.

10 . In recent years, lots of American companies have gotten behind a potential climate solution called carbon capture and storage, and the government has backed it with billions of dollars in tax preferences and direct investments. The idea is to trap planet-heating carbon dioxide from the smokestacks of factories and power plants and ship it to sites via thousands of miles of new pipelines. Communities nationwide are pushing back against these pipeline construction and underground sites, arguing they don’t want the pollution running through their land.
Now the U. S. Forest Service is proposing to change a rule to allow storing this carbon dioxide pollution under the country’s national forests and grasslands. “Authorizing carbon capture and storage on National Forest System (NFS) lands would support the Administration’s goal to reduce greenhouse gas emissions by 50 percent below the 2005 levels by 2030,” the proposed rule change says.
Some experts, like June Sekera, a research fellow with Boston University, question the timing of the proposed rule change, given community pushback across the country to pipelines planned on private land. Yet she says the Forest Service proposal to open up national parks for CO2 storage is “an end run around local towns and counties. And it’s a much simpler and way less expensive route.”
In an email, Scott Owen, press officer for the Forest Service, writes that the proposed rule change would allow the Forest Service to consider proposals for carbon capture and storage projects. He writes that any proposals must still pass through a secondary screening, adding, “The Forest Service has been ‘screening’ proposals for use of NFS lands for over 20 years as a means to be increasingly consistent in our processes and also be able to reject those uses that are inconsistent with the management of the public’s land. ” He notes the Forest Service currently does not have any carbon capture project proposals under consideration. The Forest Service has opened public comments on the proposed rule change until Jan. 2, 2024.
