1 . Food accounts for one-third of greenhouse gas emissions(排放量), but it does not yet get the attention it deserves. With global meat consumption on the rise, the truth is, we need to break bad habits before they break us. Plant-based nutrition can deal with climate change in many ways.
Did you know that one of the most effective ways to lower your carbon footprint is to eat a plant-based diet? NASA climate scientist Peter Kalmus documented his own personal experiment in low-energy living in Being the Change: Live Well and Spark a Climate Revolution.
He was able to reduce his personal carbon footprint tenfold, from 20 to 2 tons per year, by some lifestyle changes. Kalmus is a vegan(纯素食者), bikes to work, doesn’t fly, is a keen gardener and hangs his clothes out to dry. He also found living mindfully made him feel happier and even halved his food bill. Kalmus says it’s possible for the average person to cut their emissions easily. The average meat-eater in the US emits 3, 000 kg CO2 per year compared to 1, 000kg for vegans.
Another way to deal with climate change is to grow your own food. “Some of the juiciest strawberries that satisfy my taste buds were grown at home last summer in hanging baskets using organic seeds.” Kalmus said. “As well as plenty of nutritious, cheap and delicious foods, growing my own food has allowed me to get to know my neighbors. We share seeds, wisdom, and tasty soup.” Besides, composting(制作堆肥) leftovers and yard waste diverts green matter from landfills that produce the greenhouse gas and instead can help build healthy soil.
Globally, our meat-and dairy-heavy diet uses around half of habitable land on Earth to produce food. Nevertheless, with plant-based diets, we could feed the world with one quarter of the land, allowing us to return vast areas of land to nature.

2 . Scientists have found a new way to break down a group of harmful chemicals very hard to get rid of. The discovery could help solve a dangerous and growing problem — how to clean up the pollution of “forever chemicals”.
The group of chemicals known as PFAS (全氟烷基物) are pretty amazing. They’re non-stick, waterproof, and oil proof. They don’t burn easily or dissolve (溶解) in water. So scientists got really excited when they were discovered. Businesses started putting PFAS in all sorts of products, from non-stick pans to waterproof clothes, and from fire-fighting spray to carpets that resist stains. Even things like food wrappers and floss for cleaning your teeth contain PFAS chemicals.
But after a while, scientists realized the same things that made the chemicals useful also caused a real problem — PFAS doesn’t break down in nature. It doesn’t dissolve in water or bum. Not even bacteria can break PFAS down. No wonder these chemicals are known as “forever chemicals”.
As a result, PFAS chemicals surge in the environment. The chemicals are found in air, water, and dirt around the world — and in animals and people. In the US, 97% of humans have PFAS in their blood.
Luckily, scientists in the US have now found a way to break down some PFAS chemicals. Their solution requires boiling PFAS with two other very common chemicals. These chemicals can be found in just about any laboratory.
Dr. Brittany Trang, one of the scientists involved, said she didn’t even want to test the idea at first. “I thought it was too simple,” she said. But the process worked.
The research involved 10 types of PFAS, including two of the most common kinds. That’s a big step. But there are over 12,000 different kinds of PFAS. It’s important to note that the new method can only break down PFAS chemicals that have already been collected. Figuring out how to remove PFAS chemicals from the environment and collect them remains a huge challenge.

3 . Growing up in Kenya, Lesein Mutunkei, together with his family, always celebrated significant occasions by planting trees, which motivated him to protect the environment. It’s what the now 18-year-old soccer player treasures, especially since Kenya has an ongoing problem with deforestation.
Mutunkei follows in the footsteps of the late Kenyan Nobel Peace Prize winner Wangari Maathai who founded the Green Belt Movement in 1977. This initiative has resulted in the planting of over 51 million trees to date.
In 2018, Lesein decided to start a movement of his own. He started by planting one tree for every goal he scored during a football match. He called it Trees4Goals, and it has grown so much that he now plants 11 trees, one for each member of his team, every time he scores. Through this, he wants to inspire young people, specifically his fellow athletes, to follow in his footsteps, take nature conservation seriously, and promise to plant trees every time they score. As a result, some of them have adapted this practice for their sports. “Seeing that they’re taking that responsibility because of the project I started, for me, that is the biggest achievement,” he said.
The initiative has caught the attention of English football club Arsenal and Kenya’s Ministry of Environment and Forestry, which he now works with regularly and gets advice from.
Like Green Belt Movement, Trees4Goals, which has planted 5,500 trees so far, has made it. While Lesein has received some recognition for his initiative, he sets his sights on making it a worldwide phenomenon. “Football is a universal game, and climate change is a universal problem,” he explains. “It has the power to unite, educate and inspire my generation to create a safer and greener future.” This is why he wants to work with the world’s biggest football federation FIFA.
As for what others can do to fight deforestation or other environmental concerns, the teenager says it’s important to just get involved in some way, no matter how small.

4 . Sounds from human activity flood across the oceans, causing trouble to ocean creatures. And climate (气候) change may make some places even louder.
Researchers have expected the oceans to get noisier because of increasing human activity. “The more goods you buy, the more shipping you have, so the more noise you have.” says Luca Possenti, a scientist studying sound in the ocean at the Royal Netherlands Institute. But Possenti and his co-worker realized that climate change might also influence how sound travels through the water.
Human-caused climate change is changing ocean temperatures, salt levels and acidity (酸度). So Possenti’s team used computers to model how those factors (因素) influence noise levels across the world’s oceans.
When waters become more acidic, they can’t take in sound at some wavelengths as well, so those sounds can travel further, adding to the noise in some areas. This effect is relatively small. Other changes impact the sound level more, the researchers found. Changes to temperature and salt levels can change how well different layers (层) of the ocean mix, which, in turn, impacts how sound travels.
The team predicted (预测) models of the world in about 70 years if climate change continues. And then they compared them with models of the world now. In the North Atlantic, they saw an increase in sound levels in the upper 125 meters of the ocean. This was caused mostly by ice melting (融化) off of Greenland, forming a cold layer of water near the ocean’s surface. Sound traveling through water tends to go toward the coldest area. As a result, sound waves tended to get stuck in the cold top layer-spreading further out across the water, instead of traveling deeper. That increased the noisiness at this depth in the North Atlantic. The models suggested that a single ship could sound about five times as loud underwater because of this. Considering all the ship traffic between Europe and North America, that may stress animals, many of which communicate, and catch food with sound.

9 . As night falls on the streets of Shanghai, Mikiko Chen can often be found pacing up and down through the winding narrow streets of the city hunting for discarded items.
“I pick up all sorts of things, chairs, wine boxes, bowls and cups. . . it’s like treasure hunting for me, “she says. The 27-year-old digital marketer is among the first adopters of “stooping” in China, a practice that refers to picking up discarded furniture and other goods on the streets for re-use. She says the concept “stooping” was inspired by New Yorkers who often leave unwanted things on the “stoops” —or doorsteps—leading up to the entrances of buildings.
“The core concept of stooping for me is to make the best use of things,” Ms. Chen says. “It can help you to save money, but it’s not just about lowering consumption.” “It’s wasteful to throw away something that’s still usable; it’s better to share it with others who need it.”
Ms. Chen says she was among the first to use the hashtag (话题标签) #stooping on Xiaohongshu. “I initially started with posting items that people no longer used and wanted to throw away or exchange . . gradually I’m receiving hundreds of messages each day,” she says. Since then, the trend has become increasingly popular.
Ms. Chen says she is “very surprised” the concept has become a hit on social media, as older generations often stigmatize picking up things from the street or using second-hand goods. “People like my mum consider stooping as ‘rubbish picking’ and ‘scavenging’ (拾荒),” she says. “She thinks that people will look down on you for doing this.”
For Nan Zheng, an environmentalist and advocate, stooping is more than the physical act of picking up things from the streets. He created an app called “Grecycle” where people can give away or take unwanted items for free. “I think we can let more people know about the concept of stooping as an interesting and fun thing to do,” Mr. Nan says. “But then, gradually we can let people know this can also be about charity and helping others.”
1. What can we learn about Mikiko Chen from paragraph 2 and 3?| A．She is hunting for costly treasures. |

10 . During the summer of 2021, I flew to Greece to learn more about the wildfires there. I wanted to hear people’s stories, to understand what it meant to be displaced by environmental disaster.
In a cafe for people surviving the fire, I met brave children who now have to live with terrible scars, physical and emotional. I met a man who could not even speak to me, his eyes filling with tears.
I was expecting to hear a lot about loss; I was not expecting to learn so much about the attribution (归因) of blame. I came to understand how desperately people needed to blame a tangible entity (实体) –a person, a group of people, the government. Indeed, this was understandable and reasonable. The outbreak and mishandling of the fire needed to be explored, looked into and dealt with.
What surprised me, however, was that the survivors were completely silent over any mention of the climate crisis and global heating. It was made clear to me that this subject was unacceptable. Survivors felt that these issues had nothing to do with what they had suffered, and that the people actually responsible needed to pay.
But when it comes to climate breakdown, blame did not come to just one person, one corporation, one country. In Greece, the fire didn’t rage so hard because someone had set off a spark—— it raged so hard because years of global heating had dried up the land, part of a set of unsustainable (不能持续的) practices and inaction that had set our planet on fire. And now the fires are even worse.
The more I spoke to people, including climate scientists, the more I came to see that there is often a gap that separates science from public awareness. In her book “Engaging With Climate Change” Sally Weintrobe says that “many people who accept global warming continue to regard it as a problem of the future”. To my astonishment, this seemed to apply even to people who had themselves been affected directly by wildfires.
