1 . As reported in the journal Nature, one system can directly remove carbon dioxide from sources ranging from flue gas (烟道气) to the atmosphere by using electricity to induce a water-and-oxygen-based electrochemical reaction. This technological achievement could turn direct air capture (捕获) from edge industry into a promising front for climate change relief.
Most carbon-capture systems involve a two-step process: First, high-pH liquids are used to separate the carbon dioxide, which is acidic, from mixed-gas streams such as flue gas. Next, the carbon dioxide is regenerated from the solution through heating or by injecting a low-pH liquid.
“Once the carbon dioxide is trapped in these solvents (溶剂), you have to regenerate it,” says Haotian Wang, assistant professor at Rice University. “There are literally no chemicals produced or consumed with our process. We also don’t need to heat up or pressurize our device, we just need to put it into a power outlet and it will work.”
Another drawback of current carbon-capture technologies is their reliance on large-scale, centralized infrastructure. By contrast, the system developed in the Wang lab is an extensible, modular, point-of-use concept that can adapt to a variety of scenarios. “The technology can be scaled up to industrial settings-power plants, chemical plants-but the great thing about it is that it allows for small-scale use as well: I can even use it in my office.” Wang says.
Also the reactor can continuously remove carbon dioxide from a simulated (模拟的) flue gas with efficiency above 98% using a relatively low electricity input. Wang notes that the process has “no carbon footprint or a very limited footprint” if powered by electricity from renewable sources such as solar or wind. “This is great news considering that renewablel electricity is becoming more and more cost-effective,” Wang says.

2 . 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.

3 . As a young girl growing up in France, Sarah Toumi dreamed of becoming a leader who could make the world a better place. Her passion to help others was awakened when, from the age of nine, she accompanied her Tunisian father to his birthplace in the east of the country during holidays. There she organized homework clubs and activities for children.
Toumi witnessed first-hand the destructive effect of desertification (沙漠化). “Within 10 years rich farmers became worse off, and in 10 years from now they will be poor. I wanted to stop the Sahara Desert in its tracks.” A decrease in average rainfall and an increase in the severity of droughts have led to an estimated 75 percent of Tunisia’s agricultural lands being threatened by desertification.
Toumi recognized that farming practices needed to change. She is confident that small land areas can bring large returns if farmers are able to adapt by planting sustainable crops, using new technologies for water treatment and focusing on natural products and fertilizers rather than chemicals.
In 2012, Toumi consolidated (巩固) her dream of fighting the desert. She moved to Tunisia, and set up a programme named Acacias for All to put her sustainable farming philosophy (理念) into action. “I want to show young people in rural areas that they can create opportunities where they are. Nobody is better able to understand the impact of desertification and climate change than somebody who is living with no access to water.”
By September 2016, more than 130, 000 acacia trees had been planted on 20 pilot farms, with farmers recording a 60 percent survival rate. Toumi estimates that some 3 million acacia trees are needed to protect Tunisia’s farmland. She expects to plant 1 million trees by 2018. In the next couple of years, Toumi hopes to extend the programme to Algeria and Morocco.

4 . The impact of the man-made climate crisis on Antarctica is scientifically undeniable: stable ice shelves are retreating, air temperature increased by 3 degrees Celsius. krill(磷虾)numbers are declining, melting ice is contributing to sea level rise, and polar bears and seals are getting displaced. “Antarctic biodiversity could decline substantially by the end of the century if we continue with business as usual.” Jasmine Rachael Lee, lead author of the University of Queensland study says.
Published in the journal PLOS Biology, the study finds population declines are likely for 65% of the continent’s plants and wildlife by the year 2100. The most vulnerable(脆弱的)species is the Emperor penguins. In October 2022, the U. S. Fish and Wildlife Service listed Emperor penguins as a threatened species under the Endangered Species Act(ESA), as experts predict the flightless seabird will see a 26% to 47% dip in its population by 2050. “This listing reflects the growing extinction crisis and highlights the importance of the ESA and efforts to conserve species before population declines become irreversible(不可逆转).” said Service Director Martha Williams at the time.
Aside from Emperor penguins, other Antarctic specialists, like the Adélie penguin and dry soil nematodes, were also highly vulnerable. We urgently need a combination of global and local conservation action to best conserve Antarctic species. Global action and global voices to help relieve climate change—because the biggest threat to Antarctica is coming from outside of it. And then we need local actions to help protect biodiversity against local threats and give them the best chance of adapting to climate changes. This will help to save our iconic(代表性的)species like the Emperor penguins and all of Antarctica’s unique and highly adapted inhabitants. It will also help humankind, as we rely heavily on the priceless services the Antarctic provides in regulating our climate and capturing sea level in its ice sheets.

6 . In dry Niger, south of the Sahara, farmers who allowed cut trees to regrow in their fields have seen crop harvests increase rapidly. In recent decades, farmers there have allowed millions of trees to regrow on land that had once been cleared.
For centuries, rich woodlands dotted this dusty, sun-baked region south of the Sahara. By the time Ali Neino was a boy in the 1980s, however, just one lonely tree shot from his family’s land, and he could see clear to the horizon. “There was no vegetation in between the village and the fields,” recalls Neino, 45. “No trees, no plants, nothing.”
Decades of drought, land-clearing, and demand for firewood had left Niger nearly treeless. Intensive farming (密集农作) to feed the world’s fastest-growing population ensured new trees would not take root. Government efforts to reforest the area in the 1970s failed. Sixty million trees were planted; fewer than 20 percent survived.
Instead of cutting trees down, farmers in Niger now leave them standing and allow them to regrow from stumps (树桩), knowing that the soil around them will retain more water and be enriched by the leaves. On a recent walk along his family’s farm outside Dan Saga, Neino pointed to the trees growing everywhere.
In the past 35 years, as scientists begged nations to get serious about bringing forests back, one of Earth’s poorest countries, in one of the planet’s worst regions, added an astonishing 200 million new trees—maybe more. Across at least 12 million acres of Niger, woodlands have been re-established with little outside help, almost no money, and without driving people off their land. The trees here weren’t planted; they were encouraged to come back naturally, cared by thousands of farmers. Now, fresh trees are popping up in village after village.

7 . Children can gain a stronger connection with the environment through story writing, according to a new study. The research was focused on the issue of plastic litter in Latin American countries along the Pacific Ocean.
The experts set out to explore how a story-writing activity may influence the opinions of children about plastic litter, as well as how their behavior may be affected. “A key element of our project was to examine the children’s responses to questionnaires (调查表) they completed before and after writing these stories,” said study co-author Dr. Kayleigh Wyles. “We found that their knowledge on the topic increased and they became more active, as they reported doing more pro-environmental acts afterwards.”
The children were asked to use their imaginations about litter items that are commonly found on the beach, such as straws and plastic bags. They were then instructed to imagine how these items ended up on the beach in the first place. The writing project showed that children were more likely to think about ways of preventing litter from entering the environment, rather than just cleaning it up. According to the researchers, the most popular solutions suggested in the stories were the regeneration and reduction of litter.
Overall, nearly 90 children participated in the study and in more than half of the stories, the children showed awareness of the dangers of plastic pollution in the marine (海洋的) environment, including the risk of animal involvement. Many stories described consequences of animals ingesting plastic, such as injuries or death.
“Stories offer a new and different way to explore what people believe and how they understand their environment,” said lead study author Estelle Praet. “The results were truly inspiring and showed the children’s awareness of plastic’s impact on marine life and the environment.”

9 . The UK will ban all new petrol and diesel-powered vehicles from its roads beginning in 19 years for environmental reasons, a government report says.
The plan aims to start removing petrol and diesel engines in 2040. It follows a similar official statement in France and comes after the British government was ordered by the High Court to develop new plans to reduce NO2 in the air. Judges ruled that previous clean-air plans were not enough to meet European Union pollution limits in the coming years.
The British government has said the poor air quality has an unnecessary and avoidable negative effect on citizens’ health, and costs up to $3.5 billion in annual lost productivity.
Part of the new plan involves an offer of $260 million to local governments to change rules where vehicle emissions (排放量) are over EU standards. Ideas so far include changing road layouts, reprogramming traffic lights and charging a fee for the oldest and most polluting cars on the road.
The plan also includes $1.3 billion for government purchase of extreme-low-emission vehicles, nearly $130 million to improve infrastructure for electric vehicle charging stations and $378 million for remodeling existing vehicles.
Climate change is also a reason for the plan to get these vehicles off the road. “We can’t carry on with petrol and diesel cars,” Environment Secretary Michael Gove said. “It’s important that we all prepare for a significant change which deals not just with the problems of health caused by emissions, but the broader problems caused in terms of accelerating climate change.”
Gove added that local communities are partly responsible for coming up with ways to limit emissions, including possible limitations on commuters (上下班往返的人) and the addition of cleaner mass transportation options. Local leaders are called on to draw up “appropriate plans” to deal with climate challenges related to emissions, he said.

Last month, our school launched a campaign which intention was to promote environmental protection. The campaign last for one week. Firstly, there was a photo display to show the seriously pollution caused by human activities. Secondly, there was a lecture on many small step that we could take in our daily life protect the environment. For example, taking the bus and using the bike-sharing system would be a good way. Last but not the least, we students were encouraging to decorate our classrooms with recycled materials. Through the campaign, they have benefited a lot. We realize that it is our responsible to leave a better, cleaner and healthier planet for future generations.
