1 . Meteorites (陨石) can offer clues about what the early solar system was like. But finding them is far from difficult. Now, some scientists are turning to drones (无人机) and machine learning to help spot freshly fallen meteorites much more efficiently. “A team of six people on a meteorite-hunting expedition can search about 200,000 square meters per day,” says Seamus Anderson, a planetary scientist in Australia.
Around 2016, Anderson began toying with the concept of using drones to take pictures of the g round to look for meteorites. That idea blossomed into a Ph.D. project. In 2022, he and his colleagues reported their first successful recovery of a meteorite spotted with a drone. They’ve since found four more meteorites at a different site. Drone-based searches are much faster than the standard search way. “You’re going from about 300 days of human effort down to about a dozen or so,” he says.
Anderson and his workmates have used drones to search for meteorites in remote parts of Western Australia and South Australia. The team is tipped off about a fall site by networks of ground-based cameras that track meteoroids flashing through the Earth’s atmosphere. The researchers have to do a series of fun but difficult work before the hunt. They pack a four-wheel drive vehicle with drone and computer equipment, battery charging stations, generators, fuel, food, camping equipment, tables, chairs and much more. The drive to the fall site can take more than a day, often on rough or nonexistent roads. Anderson says, “You hope you don’t pop a tire.”
After arriving, the team flies its primary drone at an altitude of about 20 meters. Its camera takes an image of the ground once every second, and the scientists download the data every 40 minutes or so when the drone lands to receive fresh batteries. A typical day of flying can net over 10,000 images, which are then divided digitally into 100 million or so smaller sections. Those “tiles”, each 2 meters on a side, are fed into a machine learning algorithm (算法) that has been trained to recognize meteorites based on images of real land rocks which are spray-painted black.

2 . Recent research confirms what our farming ancestors have known for centuries about hedges (树篱). They conserve precious soil by acting as windbreaks and absorbing rainwater that would otherwise wash it from the fields. And hedges store carbon, putting them in the front line of our bi d to tackle the climate crisis.
However, hedges have had a tough time in the poor countryside, with farmers encouraged to tear them down in pursuit of maximum production and larger field s to accommodate ever-larger machinery. What’s more, some hedges have been ignored. If left to their own devices, they’ll eventually become a line of trees. Some hedges each year lose their structures and fail to fulfil the primary duty as a barrier. Around a half of the nation’s hedges have disappeared in the past century.
There are signs that “the tide is turning”. The search for net zero has aroused many organizations’ interest in the humble hedge’s role as a carbon sink. The Climate Change Committee is recommending a 40 percent increase in hedges: an additional 200,000 km. Such recommendations are starting to drive policy. Cash-pressed farmers will be encouraged to create new hedges and improve their management of existing ones under the new Environmental Land Management Schemes, which will replace many of the existing agricultural support payments in coming years. Meanwhile, initiatives such as Close the Gap, led by the Tree Council, is providing funding and support to plug the gaps in existing hedges with new planting. There’s even an app to help time-pressed farmers do a quick survey to spot where their hedges need some help.
This is a good time for hedges. Take some of the most pressing challenges facing the countryside, and indeed, the world as a whole — the climate crisis, soil erosion (侵蚀), insect attack and wider biodiversity loss — and hedges are part of the solution.

4 . Super Typhoon Rai (known as “Odette” in the Philippines) made landfall on Siargao Island in southeastern Philippines at 1:30 pm local time on Thursday, December 16. The typhoon was the 15th storm to hit the country in 2021 and was the strongest storm of 2021. Almost 16 million Filipinos were facing threats including strong winds, heavy rains, flooding, landslides, displacement and risking loss of life, home, livelihood and agriculture. Around 700,000 of them were children.
UNICEF (United Nations International Children’s Emergency Fund) expressed deep concern for children and families at risk and announced its commitment to providing support to the Philippine government. Reyn Ambag was one of the children who were rescued during the typhoon.
12-year-old Reyn Ambag is a grade 7 student living on the island of Siargao. He goes to school in San Isidro National High School which is located in the Municipality of San Isidro. With Values Education as his favorite subject in school, Reyn is always ready to help others.
Reyn is raised by his mother who is a single parent and runs a retail store alone. Aside from his mother, his cousin has also been living with them to help out in the absence of Reyn’s father. Reyn’s mother provides for all three of them. She is able to support their daily needs and Reyn’s schooling by the income she gets from the small retail store.
During Typhoon Odette, Reyn’s family stayed inside the comfort room of the school where they were evacuated (疏散) to. There, he witnessed through the window how the strong winds of the typhoon destroyed the area. They stayed there until the storm subsided and it was safe for them to go out. Upon returning to their home, they were astonished to find that their house was damaged due to the fallen trees.
After observing the delays in restoring the electricity in their community, Reyn wanted to pursue a related job in the future. “I want to be an electrician someday so that if a power cut would happen because of a typhoon, I would be able to help in restoring it for free,” said Reyn.

We met at the Leeds Grenville SPCA. We were here to find the best fit for our little family of three. In my heart, however, I think I already knew which one was the right cat. Portia, a quiet brown tabby (斑猫), watched us with partially closed eyes, seemingly saying, “Take your time…” and I know it’s going to be me. As I neared her cage, one paw extended. Finally we decided to bring home a cat that day.
After a day or two of settling in, Portia became a sort of small and furry nanny to my kids. She would travel from room to room with us during the day, usually staying closest to my son. She wanted to sit where he sat, look out the windows from which he peered, and make courageous attempts to share whatever he was eating. At night, she would sprawl onto his lap during story time. We nicknamed her “Guardian Kitten” for the way she always wanted to be where he was, watching over him as if he were her own.
One day, I was gathering leaves while my child delighted in disturbing the piles. Portia was dozing on the porch, her cars sometimes shifting toward the sound of our voices. Then suddenly, from down the street, a desperate voice cried, “No! Come back here!” The phrase was repeated and the volume increased as the speaker drew closer. A Golden Retriever ignored his owner and reached my property first. In a split second it leaped over the low fence surrounding the front yard.
The dog rushed toward my son with boundless energy and body language that expressed that it wanted to play. “Puppy!” my son exclaimed, spreading his arms apart in a welcoming gesture. Unlike me, he was not aware that this dog would, at the very least, knock him down with its uncontained enthusiasm. And I wasn’t going to be able to close the space between us in time.

6 . 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.

When I was a kid, my godparents, Uncle Nell and Aunt Frances, brought me a four-month-old puppy. She was half German shepherd, half collie. As her pink tongue touched my face with wet licks, it was love at first hug.
My family named the puppy Dusty. Although I wanted to lay my only claim to her affections, in a family of seven kids, no one lays permanent claim to the family pet.
Dusty was our dog, not “my” dog. We soon realized that she had the patience of Buddha. My baby sister often transformed Dusty’s warm fur into a nap-time pillow -- falling asleep on the rug. Like a protective mother, Dusty waited -- without moving -- until my sister woke.
Dusty doubled as a school crossing guard, too. Monday through Friday she’d walk us kids two blocks to St. Patrick’s Parochial, looking both ways to check for traffic before allowing us to cross the street. We’d wave good-bye as we entered the door, knowing Dusty would be waiting at the school door to greet us at the close of the school day.
Of all the contributions Dusty made to our family, one incident stands out far and above all others.
Late one night, Dusty rushed to my parents’ bedroom. She barked and barked. When she got no response, Dusty raced upstairs to my bedroom and my brothers’ bedroom and barked again and again. When she failed to fully wake us, she flew back down the steps and returned to my parents’ room. Finally, she got Mom’s attention.
“What are you doing, Dusty?” Mom snapped, still halfway in dreamland. Dusty persisted. Finally my mother gave in.
“Okay, what is it?”
Dusty whined and rushed out of Mom’s room. Thinking the dog needed to be let out to relieve herself, my mother followed Dusty to the front door.

8 . The ocean covers more than 70 percent of the earth’s surface and the deep sea could contain as many as 100 million species. But it’s becoming worse. Overfishing, plastic pollution, rising sea levels, and climate change are to partly blame (责怪) for the ocean’s present state.
People are talking about plastics more than ever after recognizing the heavy effect the material has on our planet. Every year, thousands of seabirds, sea turtles, seals, whales, dolphins, and fish are killed after mistakenly eating plastics.
Keeping our coastlines clean is a simple way to help the planet. After a day at the beach, make sure you’ve taken everything with you, including rubbish.
Being mindful of what cleaning products you use is another effective way to reduce your effect on the earth. Chemicals like household cleaners can move through waterways and eventually end up in the sea, affecting the health of oceans and the animals in them.

9 . The Chinese paddlefish (白鲟)-one of the world’s largest freshwater fish-has been announced extinct. Scientists say the paddlefish, also called the Chinese swordfish, is believed to have a lineage dating back at least 34 million years. With its long nose and mouth, the paddlefish could grow as long as seven meters.
But a research paper recently published in Science of the Total. Environment reported the paddlefish was now extinct. The researchers include scientists from the Chinese Academy of Fishery Sciences, Britain’s University of Kent and the University of South Bohemia in the Czech Republic.
The paper says the paddlefish was announced extinct for two reasons. It said that the fish was not able to survive because of widespread overfishing and damage to its native environment in the Yangtze River.
Researchers discovered 332 different species of fish in the Yangtze River in 2017 and 2018. But they did not find a single Chinese paddlefish They guessed the fish disappeared between 2005 and 2010. The extinction of the Chinese paddlefish was “a huge loss” to nature.
Pan Wenjing is a forest and ocean expert with Greenpeace East Asia. “The ecology of the Yangtze River is almost in ruins due to human activity in past decades” Pan said. She stressed that China had taken measures to improve the Yangtze’s environment, including a 10-year ban (禁令) on fishing.
After the extinction was reported in the news, some Chinese media and Internet users took a look back at the large creatures. Many people appeared to have not heard of the Chinese paddlefish before it was announced extinct.
“Every time I see the news of another species going extinct, heart starts to ache,” wrote one Weibo user. “Humans should not live alone on this planet,” the user added.

10 . Most environmental pollution on Earth comes from humans and their inventions, such as cars or plastic. Today, car emissions(排放物) area major source of air pollution leading to climate change, and plastics fill our ocean, creating a significant health issue to marine(海洋的) animals.
And what about the electric light, thought to be one of the greatest human inventions of all time? Electric light can be a beautiful thing, guiding us home when the sun goes down，keeping us safe and making our homes bright. However, like carbon dioxide emissions and plastic, too much of a good thing has started to impact the environment. Light pollution, the inappropriate use of outdoor light, is affecting human health, wildlife behavior and our ability to observe stars.
Light pollution is a global issue. This became obvious when the World Atlas of Artificial Night Sky Brightness, a computer-generated map based on thousands of satellite photos, was published in 2016. Available online for viewing, the map shows how and where our globe is lit up at night. Vast areas of North America, Europe, the Middle East and Asia are glowing(发光) with light, while only the most remote regions on Earth(Greenland, Central African Republic and Niue) are in total darkness. Some of the most light-polluted countries in the world are Singapore, Qatar, and Kuwait.
Sky glow is the brightening of the night sky, mostly over cities, due to the electric lights of cars, street lamps, offices, factories, outdoor advertising, and buildings, turning night into day for people who work and play long after sunset.
People living in cities with high levels of sky glow have a hard time seeing more than a handful of stars at night. Astronomers are particularly concerned with sky glow pollution as it reduces their ability to view stars.
More than 80 percent of the world’s population, and 99 percent of Americans and Europeans, live under sky glow.
