1 . The maleo (塚雉), a bird with black feathers and a pink chest, is native to Indonesia’s Sulawesi island and a few neighboring ones. The International Union for Conservation of Nature (IUCN), which identifies wildlife across the world currently facing threats, estimates only 800 to 1,400 adult maleos remain in the wild. Experts do not know how many maleos still live across West Sulawesi island. They were only able to record the presence of nesting grounds in 23 villages based on reports from locals in the area. But of those, only 18 are considered active nesting areas.
Recently, the birds have been faced with new threats, which accelerate their decline. The Indonesian government plans to move the nation’s capital from Jakarta to a new city on Borneo island, which is just a six-hour boat trip apart from Sulawesi island. The island takes on the building of new roads and seaports to be used to transport materials to the new capital. Activities also include tree clearing, digging, and removing stones. The process already has changed the forest environment on West Sulawesi and is harming maleo nesting areas near the beach. These changes have made the trip for maleos to lay their eggs increasingly difficult.
Another problem has been poachers. The Associated Press reports that, regardless of official ban, they steal maleo eggs that the males’ parents have hidden in the sand, and sell the eggs for about $1 to people as food. The eggs are a traditional gift for many people in Mamuju and other parts of Sulawesi.
“As far as I know, maleo birds are in decline,” said Andi Aco Takdir, chief of the West Sulawesi Forestry Agency. He pointed to several reasons for the decline, including destruction of beach areas, and expanding human development activities. He added that government officials there are prepared to take steps to protect the maleos even with the new capital development. Andi said, “Nature conservation must be used as an achievement and must not be built leaving behind problems.”

2 . Sara Dykman is on a 10, 000-mile bike trip, following the monarch butterfly from Mexico through the UnitedStates and Canada and back again. The purpose of her journey is not just to mark the butterfly’s migrating (迁徙) road, but to warn about the threat it faces — and what we can do to help it.
When I reached Dykman by phone, she was biking through Iowa cornfields. She said she feels more upset than usual, because of what she is seeing — or not seeing — on her travels: Fewer butterflies and milkweed. “In the last two decades, the butterfly population has declined by about 90 percent as a result of the loss of milkweed, a native plant that the butterflies need as part of their life cycle,” she said.
Butterflies go through a four-stage life cycle. In February and March, the adult monarch butterflies come out of winter sleep to look for a mate. Then they migrate north and east to lay their eggs on milkweed plants. It takes about four days for the eggs to hatch. Then the baby caterpillars (毛毛虫) spend much of their time eating milkweed in order to grow. About two weeks later, the fully grown caterpillars will attach themselves to plant branches or leaves to change into butterflies.
But Dykman is not in total despair. A solution, she says, exists within the reach of everyone who owns a home; simply planting some milkweed in the yards to help the butterflies on their journey.
Dykman lives a life as simple and rootless as the butterflies she loves. She doesn’t own a house or car or eat out at restaurants. She carries only what she needs; a sleeping bag and clothing. People help along the way by providing a place to stay and a meal.
“I have failed at everything normal, but I’m pretty good at doing the less normal things,” she admits in her new book Cycling With Butterflies.
“But this trip is about solutions, and it’s about helping people see the consequences of their actions,” she said on the phone.

3 . Humans can make do with scarves, coats and gloves in cold weather. Some animals can hibernate (冬眠) for the winter. A new study finds that reptiles (爬行动物) and birds do something that is similar to hibernation, but a little different. In very cold weather, their body temperatures greatly drop into an energy-saving state in order to survive. The ability to thermoregulation (体温调节) for reptiles and birds is possible.
In Texas, where the city of Beaumont reached a low of 18 degrees Fahrenheit last month, it looked as if alligators (短吻鳄) had died of cold — yet alive in iced-over water. By ensuring their long noses stayed above the water line, the cold-blooded creatures were able to lower their body temperatures to survive the sudden short period of very cold weather. The process, in the case of cold-blooded animals like reptiles, is called brumation — it’s like a short state of hibernating. While in this state, reptiles become sleepy and they can go for a long time without eating or drinking. For example, alligators can be in brumation from just a few hours to months.
Like reptiles and mammals, birds can go into a state called torpor in order to save energy under very cold conditions. “Torpor is somewhere between a short sleep and hibernation,” said Justin Baldwin, a PhD candidate in biology at Washington University in St. Louis. Baldwin studied 29 species of hummingbirds living in Colombia. Researchers found that hummingbirds can enter into deep or shallow torpor, depending on several factors, including their size and weather conditions. In deep torpor, the birds are much more likely to be affected by disease. And what’s more, they would be easily harmed by their enemies.
Some bird lovers want to help the birds when they are in torpor. For example, the Bird Alliance of Oregon offers a few tips on how to keep the birds from danger.

5 . Issues such as global warming and sustainability have become passionate concerns for many of the concert industry’s fans and increasingly for the musicians. Coldplay, a pop band whose members scored their first big hit in 2000 with a song called Yellow, announced in November that it wouldn’t go on tour to promote its latest album, Everyday Life, until it could find a way to make concerts more sustainable and greener to the environment.
It’s not always easy to walk the talk. A growing number of artists, including Peggy Gou, have environmental demands built into their contracts when they tour, such as bans on plastic tableware. But there’s almost no way of avoiding carbon emissions produced by a tour, which involves moving hundreds of people and tons of equipment across large distances.
Lisa Pomerantz, who books travel for acts says that real change will require action by venue owners, concert promoters, and the fans. Major acts like Coldplay can afford to stop touring while figuring out how to lessen their environmental impact. But lesser-known artists can’t stay off the road, since streaming earnings haven’t been able to compensate (弥补) for the collapse in CD and downloaded music sales. Even when concerts are aggressive about being more sustainable, the impact of audience travel can easily swamp (淹没) their efforts. For bigger acts, this can represent as much as 80% of the carbon footprint, according to a 2015 study. Another analysis showed that roughly a third of the tour’s carbon footprint came from a venue’s power consumption.
Still, even the most green-conscious bands must balance their desire to be more sustainable against the financial necessity of touring. “I absolutely think you can go on tour and have a concern about the environment. It’s a matter of just keeping our carbon footprint as low as possible,” says Flavian Graber, lead singer of We Invented Paris.
1. Why did Coldplay stop its promotion tour?| A．Because it had already released a hit. | B．Because it wanted a more environmentally friendly concert. |
| C．Because its latest album needed further improvement. | D．Because they could afford the money. |
| A．Make it. | B．Talk it. | C．See it. | D．Appreciate it. |

6 . Hotter, drier conditions over the past four decades have been decreasing the rainforest birds’ body size while lengthening their wings, a study published in the journal Science Advances said on Friday. “This maybe an adaptation to hotter temperatures. Even in the middle of the primitive Amazon rainforest, we are seeing the global effects of climate change caused by people,” said Vitek Jirinec, lead author on the study.
The scientists have studied measurements and weigh-ins of 77 different bird species in the Amazon rainforest since the early 1980s. Nearly all of the bird species have gotten lighter as time goes on. On average, most species became about 2% lighter every decade. These birds don’t vary that much in size,” said co-author Philip Stouffer, a professor of conservation biology at Louisiana State University. “But when everyone in the population is a couple of grams smaller, it’s significant.”
The researchers found that bird species living in higher parts of the forest—as opposed to closer to the forest floor —saw the most pronounced changes in terms of body composition. Those are the species most exposed to high temperatures. Longer wings and smaller bodies mean that birds have to useless energy to move around, helping them stay cool.
Brian Weeks of the University of Michigan in 2019 researched the average sizes of 52 species of migratory birds in North America from 1978 to 2016. He also found all of them had smaller bodies and longer wings in 2016. This is another example of climate change-human actions globally—affecting a fundamental thing such as the size and shape of the birds. The same effect is likely to be true of other species across the world living in extreme environments.

Spotted lanternflies (斑点灯笼蝇) are an invasive species. Since 2014, they have been seen all across the eastern United States. The insects are harmful to many plants, and can disturb entire ecosystems. State officials have urged people to kill spotted lanternflies wherever they see them.
When Joy saw the pests in her school courtyard, she thought she had to do something. “I’ve always wanted to take environmental action,” she says, “and show people that no one is ever too small to make a difference.”
So she started a club called Squash (压扁). Its mission is to kill spotted lanternflies around the school. More than 20 students have joined. At first, they trapped the pests in empty water bottles and then squashed them. In a single day, the club managed to kill more than a hundred spotted lanternflies.
Joy wanted to do more. With research, she discovered a plant called milkweed. It’s nutritious for pollinators (传粉昆虫) such as monarch butterflies but poisonous to spotted lanternflies. Joy thought that using milkweed along with the traps made specifically for spotted lanternflies would be a better way to kill them. The issue was that they didn’t have enough money to buy milkweed and the traps.
The kids were hoping to raise money for their school to address the big problem. Their goal was to raise $200, the cost of the equipment needed to kill spotted lanternflies around their school. They got part of the way there, with about $75. They decided to attract more fundraisers. “We discovered that if you find your voice,” Joy says, “you can do much more.”
In May, Joy and other students from Squash gathered in Columbus Park, in New York City. They set up a table with lemonade, cookies, and origami figures for sale. The money will be used to buy milkweed and the traps.

10 . Can you name a famous elephant? Babar, perhaps? Or Dumbo? Though these names may be memorable to humans, they sound nothing like the names elephants give each other. “If you’re an elephant, your name is something more like a low, rumbling sound (隆隆的声音),” scientists say. Researchers have found that African elephants emit sounds in response to individuals in their social group, and the receivers respond accordingly.
Researchers recorded 527 elephant calls in northern Kenya and 98 calls in southern Kenya. They then distinguished which members were separated from the herd at the time of each call, or which members were close to the herd. Researchers correctly identified the receivers of 20.3% of the 625 recorded calls. This marks a step forward in understanding how these highly intelligent animals communicate.
“There’s a contact rumble, an anti-predator rumble and a greeting rumble. If you look at a spectrogram (声谱图) with your eyes, they all look almost exactly the same,” said Caitlin O’Connell-Rodwell, an elephant biologist at Harvard Medical School. “That’s why artificial intelligence(AI)has been exciting. It allows us to really figure out what the elephants are saying.”
As it turned out, the calls were distinct to the receivers. Even calls from different callers to the same receiver were similar. The pattern was less obvious than it was between a single caller and his or her receiver. This may be because rumbles encode multiple messages at the same time, so the AI system in computer model may not have been able to pick out the “name” used in each call. “It just highlights the complexity of what’s going on. And we’re not skilled enough in these measurements to figure out what’s going on,” said Caitlin.
However, the research shows how elephants are navigating through a large landscape and can still keep in touch with specific individuals. It allows them to spread out much further and still have very close tabs on individuals, not just the group.
