2 . Deforestation in tropical (热带的) regions of Asia, Africa and the Americas has reduced the cooling effects of trees. “The temperature change associated with deforestation over the 15-year study period is equal to a century of global warming, happening almost instantly, at these locations,” says Luke Parsons at Duke University in North Carolina.
Now, by using data from population surveys and mapping tree cover loss over a 15-year period, Parsons and his colleagues have estimated the effect of deforestation on outdoor workers across 41 countries. He says climate change has already pushed tropical locations right to the edge of what would be considered safe for heavy outdoor labour and that deforestation causes those locations to be even more precarious.
Parsons and his colleagues used land surface temperature measurements from satellites, and collected humidity (湿度) data, to estimate how hot an average day felt to outdoor workers in regions which either lost or maintained tree cover between 2003 and 2018. “The study focuses on what you would think of as a ‘feels-like’ temperature. It takes into account how well you can cool yourself by sweating, which is affected by humidity, as well as the temperature,” says Parsons.
The researchers then turned to population surveys to estimate the number of outdoor workers in these areas. This revealed that some 2.5 million outdoor workers in Asia lost at least half an hour of safe work per day, between 2003 and 2018, due to increased temperatures in deforested regions. Nearly 200,000 outdoor workers in the Americas and some 31,000 people in Africa lost this amount of safe work time each day. Regions that maintained forest cover generally stayed cool, and less work time was lost.
It is important to remember that, due to the scale (规模) of the study, the team didn’t measure actual worker hours on the ground across the entire tropics, says Parsons. This means the assessment of lost worker hours is based on theoretical considerations rather than direct observations of behaviour.

3 . In many parts of the world there may not be much rainfall, but there is a fair amount of water vapor (水蒸气) in the air — particularly at night. An experimental new device draws in that vapor, and uses it to water eatable plants.
Known as SmartFarm, the small device designed by a team at the National University of Singapore, led by assistant professor Tan Swee Ching aimed to help address two of the world’s biggest problems — water shortage and food shortage. It’s a transparent (透明的) box that has vegetable plants growing in soil on the bottom — on top, a hydrogel (水凝胶) panel lies beneath a solar-powered motorized cover.
The hydrogel is very absorbent, readily drawing water vapor from the cool night air while the cover is open. An integrated timer closes it at daybreak, with the sun’s rays subsequently heating the hydrogel through the clear cover material. The gel responds by releasing its stored water in the form of vapor, which turns into liquid on the inside of the cover. When that cover periodically slides open throughout the day, the liquid gets wiped off along the inside edges of the box and runs into the soil.
According to scientists, the gel can absorb up to 300 times its weight in water at night. During the day, it releases that water at an hourly rate of 2.24 grams of water per gram of gel. And what’s more, the released water meets World Health Organization standards for drinkability.
Tan said, “The SmartFarm concept greatly reduces farms’ demand for water and is suitable for urban farming techniques such as rooftop farming. This is a significant step forward in easing water and food shortage.” He believes the SmartFarm device can be further improved with additional functionalities before it moves to mass and commercial production. For example, it can include wireless networking capability to enable users to monitor and control the process using smartphones.

4 . Damon Carson must have one of the most interesting inboxes in the world. On any given day, in his office in Denver in the western US state of Colorado, he will field numerous inquiries from people looking to unload things. We’re not talking about someone trying to dispense with an old refrigerator or some out-of-fashion clothing, but companies.
Picture large companies looking to unload massive amounts of waste that would otherwise go to the landfill.
For example, Carson got a request from a battery company to deal with 22 tonnes of barium sulfate (硫酸钡) used in lead-acid batteries. A load of plastic garbage cans from a discount store were just waiting for him to repurpose them. And a recreation company wanted to know if Carson was interested in 360 kilograms of blue ropes, which they no longer needed to make the handles on coolers.
“They don’t want to just throw the waste away,” he explains. “Nor should they. Because it has value.” He is a matchmaker of the never-ending waste stream, trying not to pair people with people, but things with people. For nearly a decade, his company, Repurposed Materials, has been involved in this business. He’s not looking to recycle the things he gets-breaking them down to make something new-but rather finding a second life for cast-off goods in their original forms.
Once working in construction, Carson was familiar with an almost everyday phenomenon. “You’d open up one of these big construction dumpsters (大垃圾桶) and things would start falling out,” he says. He would find perfectly good windows still covered with plastic from the factory. “You can’t wrap your mind around how wasteful America is until you run a waste company,” he says. He began thinking about creating a sort of secondhand hardware store that would sell unwanted materials and keep them out of the waste stream. Then, in 2010, a business was born.
1. What does the underlined phrase “dispense with” in the first paragraph mean?| A．Make use of. | B．Look forward to. |
| C．Get rid of. | D．Come back to. |
| A．To prove Carson’s tough work. | B．To indicate Carson’s “big business”. |
| C．To appeal for waste management. | D．To explain the source of the material. |
| A．By creating something new. | B．By selling them to companies. |
| C．By recycling them to save energy. | D．By getting others to use them. |
| A．His disappointment at America. | B．His love for secondhand hardware. |
| C．His exposure to too much waste. | D．His experience in a waste company. |

7 . French company Airseas, has promised to help big goods ships reduce their fuel consumption (能源消耗), and cut their greenhouse gas (GHG) emissions (排放) by 20%. And they’re doing this with the Seawing — a 1,000 square meter kite that will fly 300 meters above the water’s surface. So the shipping industry is rediscovering the joy and efficiency of sails (帆).
The large, ship-sized kite is now being developed, and the company plans to open a factory to produce the Seawing in 2026. Once produced, Airseas has promised that launching and operating a Seawing on a goods ship will be automated (自动化), making it easy for crews (船员) to use. The crew can simply press some buttons and a large kite will rise into the sky. That’s not to say that the goods ships won’t use their engines at all, but the kite will take some pressure off of those engines and will reduce the need for fuel. The wind will move the ship, just like it did for hundreds of years in the old days before industrialization.
Lowering emissions by 20% may not seem like a big deal, but moving large amounts of goods back and forth on the high seas creates 3% of the world’s greenhouse gas emissions. That’s more than the airline industry, which produced about 2% of the world’s emissions in 2021, according to the International Energy Agency. Shipping is also a massive industry, and one worth focusing on for lowering emissions. About 90% of the world’s traded goods are moved around through ships, according to the International Chamber of Shipping.
Some companies are expecting this new version of sails. Japanese shipping company, “K” Line has placed orders for the Seawing kite, and the European Union has also invested more than $2 million in funding.

8 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

9 . Damon Carson calls himself a matchmaker (媒人) of the never-ending waste of American society, trying not to pair people with people, but things with people.
In the late 1990s, Carson was on break from business school in Vail, Colorado, when he discovered the vast world of waste. He began thinking about creating a secondhand store that would sell old materials and keep them out of being wasted. As a result, in 2010, his company, Repurposed Materials appeared.
For nearly ten years, his company, Repurposed Materials, has not been looking to recycle the waste he gets — breaking it down to make something new — but rather finding new homes for thrown-away goods in their original forms.
Carson, a husband and father of three adult children, is far from wasteful. Frugal is how he describes himself. The clothes he’s wearing all came from a charity shop; his truck was bought with 290, 000 kilometers driven.
“Why break something down, why melt something down, if it still has value?” he asks. An old oil-field pipe might be melted down and turned into a car bumper, but it still takes an amount of power to finish the complete change. Why not leave it as a steel pipe? Why not turn it into a fence post on a farm? The only cost is transport.
American industrial facilities create and throw about 7.6 billion tons of unwanted industrial materials every year. For the moment, Carson’s unique business finds new lives for millions of kilograms of industrial waste every year.

10 . When I give public lectures about the climate crisis, the most common question people ask is: “Are you an optimist?” My answer is yes. The second most common question is: “What can I, personally, do?”
That’s a tough one. About half of all greenhouse gas emissions come from electricity generation and industrial fossil-fuel use. Some people have argued that calls for individual action actually distract us from company’s responsibility. Oil giant BP promoted the idea of a carbon footprint, moving attention to its customers who, it suggests, should take personal responsibility by lowering their carbon footprints. One study found that focusing on personal activity will ruin support for more effective policy initiatives (提案) such as a carbon tax.
Another problem with personal behavior is that people do not like to be told what to do. As former congressperson (国会议员) Bob Inglis of South Carolina said, people think, “You’re saying that I shouldn’t have this house in a suburb? I shouldn’t be driving this car.”
Cutting meat consumption (消耗) is a powerful and personal thing most Americans can do to deal with the climate crisis, and they can do it immediately. About 40 percent of greenhouse gases come from agriculture, deforestation and other land-use changes. Meat—particularly beef—drives climate change in two ways: first, through cows’ emission of methane(甲烷), and second, by destroying forests as land areas as required to the cows to live on. Despite the economic slowdown caused by the COVID 19, atmospheric greenhouse gas levels continued to rise in 2020, in large part because of emissions increase in the Amazon as rain forests were changed into land for cattle to satisfy the global demand for beef. By eating less beef, we can start to reduce that demand.
You do not have to become a vegan (素食主义者) to do this. Cutting back on red meat also has the added benefit of being good for your health. While I wouldn’t advise governments to order people to stop eating hamburgers, if anyone asks, “What can I do?” a simple and accurate answer is: “Eat less meat. It’s in your control, and you can begin right now. It benefits both you and the planet.”
