1 . Climate change is causing more areas to turn into deserts. This issue is affecting the lives of 250 million people as land that used to be good for farming becomes dry and unproductive. Around one-third of the world’s land is impacted, including regions in Africa, southern Europe, Asia and America.

Sand to Green is a Moroccan company that can transform a patch of desert into a sustainable (可持续的) and profitable plantation in five years, according to Wissal Ben Moussa, its co-founder and chief agricultural officer. The solution is using agroforestry (农林业)to create a new kind of agriculture that is sustainable and that can be resilient (有适应力的) in front of climate change.

The system can be set up close to any source of salty water, which Sand to Green cleans using energy from the sun. It then grows different types of fruit trees and plants together in the same area—a method called mixed planting—and waters the plants’ roots directly with the cleaned water, to reduce water loss to the air. The soil is regenerated using what Sand to Green calls “green manure”, a mixture that includes compost, biochar(生物炭)and microorganisms that help the soil “wake up”. Biochar is a form of charcoal that can help dry soil hold on to water.

In a five-hectare trial in southern Morocco that’s been running since 2017, Sand to Green has tried out a variety of plants in search of the best performers. Among the intercropping herbs (草本植物) that have been successfully trialed are rosemary, geranium, vetiver and citronella, which Ben Moussa describes as “very low-maintenance and very high-profit”.

Sand to Green is now working to scale up to a 20-hectare commercial site, also in southern Morocco. It says a site of that size would cost around $475,000 to set up and would start bringing financial returns in about five years.

According to Ben Moussa, with this system they create biodiversity, which means better soil, healthier crops and a bigger yield. The plantation can generate 1.5 times more yield, thus making more money than a farm that grows only one type of crop in the same space.

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.

1. What made Lesein get interested in environmental protection?

A．The influence of his family.

B．Wangari Maathai’s huge assistances.

C．The demand of the football team.

D．His fellow athletes’ encouragement.

2. Why did Lesein found Trees4Goals?

A．To gain Kenya’s support.

B．To set an example for others.

C．To catch Arsenal’s attention.

D．To show his achievements.

3. What is Lesein’s hope for the future of Trees4Goals?

A．Promoting football’s development.

B．Going global with the help of FIFA.

C．Beating climate change completely.

D．Getting beyond Green Belt Movement.

4. What can we learn from Lesein’s story?

A．Fame is a great thirst of the young.

B．A youth is to be regarded with respect.

C．Positive thinking and action result in success.

D．Success means getting personal desires satisfied.

5 . Vast lands of America are dominated by corn, nearly 100macres of it, stretching from Ohio to the Dakotas. What once was forest today produces the corn that feeds people, cattle and, when made into ethanol (乙醇), cars.

Now, the nation’s airlines want to power their planes with corn, too. United Airlines signed a deal with a Nebraska ethanol company to buy enough sustainable fuel, to power 50,000 flights a year. The government could decide on its tax incentives (税收激励) for the industry as soon as December. “Mark my words, the next 20 years, corn farmers are going to provide 95% of all the sustainable airline fuel,” President Biden said in July.

The airlines’ ambitious goal would likely require nearly doubling ethanol production, which airlines say, with great expectation, would decrease their greenhouse gas emissions. If they succeed, it could transform America’s Corn Belt, stimulating farmers and ethanol producers, but potentially further damaging one of the nation’s most important resources: groundwater.

Corn requires a lot of water to grow and it can take hundreds of gallons to produce a single gallon of ethanol. But as airlines take the idea of ethanol, the vital groundwater faces serious risks. “We’re on track to massively increase water usage without any real sense of how sensitive our groundwater is,” said Jeffrey Broberg, who is concerned about groundwater in Minnesota, a major corn state.

The Department of Energy said in a statement that “water use is a critical part of the conversation surrounding bio-energy sustainability”. It pointed to a 2022 department study that concluded that the United States could significantly reduce pressure on groundwater by shifting fuel production away from water-intensive crops like corn, instead growing more crops that don’t require irrigation (灌溉), like various types of straw, grasses and trees. Hopefully, a better approach will be soon studied and adopted.

A．Expand the corn planting area.

B．Use some alternative materials.

C．Cut down the daily water usage.

D．Turn to the government for help.

6 . “The era of global warming has ended and the era of global boiling has arrived,” the UN secretary general, Antonio Guterres, said after scientists confirmed July 2023 was the world’s hottest month on record.

“Humanity is in the hot seat,” Guterres told a press conference on Thursday. “For vast parts of North America, Asia, Africa and Europe, it is a cruel summer. For the entire planet, it is a disaster. And for scientists, it is clear that humans are to blame. Climate change is here, it is terrifying, and it is just the beginning. The era of global warming has ended; the era of global boiling has arrived.”

Guterres urged politicians to take swift action. “The air is unbreathable, the heat is unbearable, and the level of fossil fuel profits and climate inaction is unacceptable. Leaders must lead. No more hesitancy, no more excuses, and no more waiting for others to move first. There is simply no more time for that.”

“It is still possible to limit global temperature rise to 1.5℃and avoid the very worst of climate change but only with dramatic, immediate climate action. We have seen some progress, but none of this is going far enough or fast enough. Accelerating temperatures demand accelerated action.”

The WMO secretary general, Petteri Taalas, said, “The need to reduce greenhouse gas emissions is more urgent than ever before. Climate action is not a luxury but a must.”

Other climate scientists confirmed the findings. Karsten Haustein at Leipzig University found the world was 1.5℃ hotter in July 2023 than in the average July before industrialisation.

Marina Romanello, a climate and health researcher at University College London, said, “We have data showing how the very foundations of health are being undermined by climate change. But we still have time today to turn the tide and to ensure a liveable future for us and our children.”

7 . Nature has the power to alter an element’s identity with time and space. This is evident by the transformative effect Britain’s deep coal mines have been showing after decades of being one of the biggest reasons for pollution. Now, they’re being employed to supply green energy to the town of Gateshead. The town is the first place to experience something like this in the country, but the success of the phenomenon has encouraged the authorities to apply it to other towns.

In 2021, coal was just producing 2% of electricity in the UK. Most of the electricity in the country is being supplied through oil and gas. This has resulted in massive abandoned coal mines all across the country. As years went by, these mines were flooded with water, making it a source of geothermal（地热的） energy, which is used to generate heat and electricity. Gateshead hosts such a mine in its town, whose council, therefore, launched a mine water project in March 2023.

The authorities put in a large central heat pump in the mine. Mine water can often sit with a temperature of 45℃. The water is then pumped using appliances to home heat pumps. The process increases the temperature further. The water then goes ahead and warms up the interior space and home water supply. After the heat from the water has been used, it’s sent back to the mine where it again goes through the same process. The project has been successful in supplying low-carbon heating to 350 high-rise buildings, a college and several office buildings.

“Recovering heat from mine water below the ground within abandoned coal mines provides an exciting opportunity to generate a low-carbon secure supply of heat, benefitting people living or working in buildings on the coalfields,” said Gareth Farr, head of heat and by-product innovation at the Coal Authority.

The water resources through the mines are estimated to be two billion cubic meters or half the amount of water in Loch Ness. Farr added, “With many millions of people living upon abandoned coalfields in Great Britain, the potential for mine water heat could be significant.”

10 . In recent years, the popular idea of reducing carbon footprints by eating locally to cut down food miles has come under close examination. However, a recent study published in Nature Food indicates that global food miles might account for as much as 20 percent of food-related emissions, a significantly higher percentage than previous estimations. This statement begs the question: Are food miles more significant than we initially believed?

Food miles represent the distance food travels from production to consumption, with previous studies suggesting that the emissions from these miles are tiny compared to the emissions produced during the food growing process. For instance, producing one kilogram of beef generates almost 99 kg of CO₂, while apples only produce 0.4 kg per kilogram. If the goal is to minimize dietary carbon footprints, it would be more beneficial to choose foods with lower overall carbon footprints, even if they have to travel a distance. Therefore, reducing meat and dairy intake could prove to be a more effective strategy.

The recent study doesn’t contradict (相矛盾) this conclusion. The reason why the reported proportion is higher is that the calculation includes all transport involved, including the transportation of fertilizers, farm equipment, and pesticides (杀虫剂). Hannah Ritchie, a researcher at the University of Oxford, suggests that a term other than “food miles” would be more appropriate to avoid any confusion. If the study had followed the standard definition of food miles, the per-centage would drop to 9 percent, which corresponds more closely with the 4 to 6 percent found in prior research.

Moreover, the study theorizes that even if all food was produced in the countries where it is consumed, the reduction in emissions would only be 1.7 percent overall. This is due to the fact that a larger proportion of food would be transported by road rather than by sea, with trucks producing higher emissions per ton of cargo than ships.

“So, overall, the bottom line is still that what you eat has a much bigger impact on emissions than the distance that food has to travel to reach you,” said Ritchie.
