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 . “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.”

4 . A recent global study, which surveyed 10,000 young people from 10 countries, showed that nearly 60 percent of them were extremely worried about the future state of the planet. The report, which was published in The Lancet, also showed that nearly half of the respondents said that such distress affected them daily, and three quarters agreed with the statement that “the future is frightening.” This, along with many other studies, shows clearly that climate change is not just a threat to the environment that we inhabit. It also poses a very real threat to our emotional well-being. Psychologists have categorized these feelings of grief and worry about the current climate emergency, a common occurrence among youth today, under the label of “eco-anxiety”.
Eco-anxiety doesn’t just affect young people. It also affects researchers who work in climate and ecological science, burdened by the reality depicted by their findings, and it affects the most economically marginalized (边缘化的) across the globe, who bear the damaging impacts of climate breakdown.
In 2024, eco-anxiety will rise to become one of the leading causes of mental health problems. The reasons are obvious. Scientists estimate that the world is likely to breach safe limits of temperature rise above pre-industrial levels for the first time by 2027.
In recent years, we’ve seen wildfires tear through Canada and Greece, and summer floods ruin regions in Pakistan that are home to nearly 33 million people. Studies have shown that those impacted by air pollution and rising temperatures are more likely to experience psychological distress.
To make matters worse, facing climate crisis, our political class is not offering strong leadership. The COP28 conference in Dubai will be headed by an oil and gas company executive. In the UK, the government is backtracking on its green commitments.
Fortunately, greater levels of eco-anxiety will also offer an avenue for resolving the climate crisis directly. According to Caroline Hickman, a researcher on eco-anxiety from the University of Bath, anyone experiencing eco-anxiety is displaying entirely natural and rational reactions to the climate crisis. This is why, in 2024, we will also see more people around the world join the fight for climate justice and seek jobs that prioritize environmental sustainability. Campaigners will put increased pressure on fossil fuel industries and the governments to rapidly abandon the usage of polluting coal, oil, and gas.
It’s now clear that not only are these industries the main causes for the climate crisis, they are also responsible for the mental health crisis, which is starting to affect most of us. Eco-anxiety is not something we will defeat with therapy, but something we will tackle by taking action.

5 . Falcons are powerful birds that may be trained to hunt in cooperation with humans. The art of training falcons as “hunting dogs of the skies” is called falconry (训鹰术). It was developed in the ancient Arabian Desert around 4000 B. C. In the past, falconry mainly involved hunting with falcons to supplement one’s diet. But now, it has become the favorite sport and pastime in the Arabian Peninsula.
Falconry includes three major processes: acquiring the falcons, training them, and hunting with them. Every year, falconers begin capturing wild falcons in June and July, the migration season. The best birds to catch are the ones with naturally nurtured hunting skills, aged one or two years. Once the falcons are captured, their heads are immediately covered with a leather hood. This is essential because they imprint as their master whomever they see first after the hood is removed. Right after a bird is caught, the training process starts. It begins by depriving (剥夺) the bird of food to make it easier to tame. The birds are taught to know their own name and respond to their master when called. Arab falconers live with their birds day and night in order to build a strong relationship with them.
By the end of October or mid-November, the trained falcons are ready to hunt in the desert. They have excellent vision, 2. 6 times greater than that of a human. They are also the fastest divers on the planet. One hunting technique that sets them apart from other animals is that they can be trained to deliver their prey, without killing it first. This is vital in Islamic culture because animals used for food must still be alive to ensure that the meat is halal, that is, properly prepared according to Islamic law.
Falcons have played such a crucial role in traditional Islamic cultures that a number of countries in the Middle East have made them their national bird. Falconry has grown so popular that specialist hospitals have been established to take care of these magnificent birds. Falcons are even issued their own passports. They are the only animals in the United Arab Emirates that are legally allowed to travel inside planes, enjoying a level of luxury that some humans can only dream of.

6 . American researchers say they have developed a method to remove carbon dioxide (CO2) from the sea. The researchers say the process can be an additional way to help reduce CO2 from the environment to fight the effects of climate change.
Plants and currents in the ocean absorb large amounts of CO2 from the atmosphere. The sea is estimated to have drawn in about 30 percent of carbon emissions since the Industrial Revolution. But carbon emissions also make oceans more acidic (酸性的). It can hurt coral reefs, which are sensitive to ocean acidity. Reef damage then do damage to the growth of many kinds of sea life.
Gaurav Sant, director of UCLA’s Institute for Carbon Management, said the technology is meant to use the ocean’s natural abilities to reduce carbon levels in the sea. The process sends an electrical charge through seawater flowing through tanks on a large boat. That sets off a series of chemical reactions that turn the carbon emissions into a solid mineral that includes calcium carbonate (碳酸钙). The seawater then returned to the ocean and can pull more carbon dioxide out of the air. The calcium carbonate settles to the sea floor.
The process has already been demonstrated in California. Researchers are working on plans to launch another project in Singapore. The two projects are expected to be fully operational by 2025. Researchers say they are expected to remove thousands of tons of CO2 per year. If successful, the plan is to build additional centers to remove millions of tons of carbon each year.
But experts say even if that amount of carbon can be removed, that is still thousands of times less than what will be needed to effectively reduce climate change. Margaret Leinen, director of an ocean research center, said, “While the process will likely be effective, I question how much effect it will have on climate change over a long period.” Sant said the success of such technology will greatly rely on “how fast you can build the centers”.

7 . 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.

8 . 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 . Keeping plants at home is a healthy and comfortable way of life. The following houseplants can create a most beautiful piece of green for your home.
Bird’s Nest Fern (蕨)The bird’s nest fern is a good choice for anyone with a house that wouldn’t support sun-loving species. It’s a hardy fern variety adapting to living on forest floors, where the air tends to be cool and damp. It likes to be misted as well, but this doesn’t always mean you need a misting bottle—spraying (喷洒) it in the sink or hanging it near a shower often works as well.
Chinese Money PlantThis is a flowering species that might be most appropriate for experienced plant gardeners looking for a new challenge. It prefers a moderate amount of indirect light, and tends to dry out slightly between watering sessions. It produces new plants easily without any input, directly from its root system. These can coexist in the same pot for a time.
Resurrection PlantThis native of the Mexican desert has adapted to surviving in extreme drought by curling (蜷缩) into a ball and remaining in seemingly lifeless state for years, if necessary. In this form, it can be transported by the wind across the dry landscape to areas with water. It will revive within hours in a shallow bowl of water, unfolding and transforming into a fresh and green moss (苔藓).
Snake PlantThis is a striking houseplant that can be an especially good option for new plant owners who you might not trust to keep a plant alive. It grows happily in almost any condition. While it prefers bright light, it doesn’t mind shade or even artificial light. Plus, thanks to its thick, fleshy leaves, it stores water with remarkable efficiency, which makes it survive without water in the earth.

10 . New research shows that removing black rhinos’ horns (犀牛角) to make them less attractive to illegal hunters is reducing their territory (领地) sizes and making them less sociable with each other.
The study, published in the journal PNAS, found that dehorned South African rhinos have home ranges that are 45 per cent smaller than those of complete animals, and that they were 37 percent less likely to engage in social interactions.
“The big, dominant bulls that used to have very large territories that overlapped with a lot of females may now have much less territory and much less reproductive (繁殖的) success,” says Vanessa Duthé, who led the work at Switzerland’s University of Neuchâtel.
“It’s really hard to predict the effects of this,” she says. “It doesn’t mean that population success will necessarily decline, because it might open up gaps for younger males that would not have had the space or the means before.” Indeed, a University of Bristol study published last year showed that dehorning (去角) does not negatively affect populations overall.
But such unintended behavioral consequences necessarily feed into judgments about whether this highly invasive procedure is worthwhile. Remarkably, perhaps, there is little hard evidence either way. “No one’s put all the data together to say whether it’s a really effective measure,” says Duthé.
“What is clear is that the introduction of dehorning and a decline in illegal hunting has occurred at the same time,” she adds. “But dehorning has been accompanied by other conservation measures that may be more effective.”
“It’s incredibly complicated,” says Lucy Chimes, a member of the Bristol team. “There are so many other factors involved. You have to consider what other security measures are being carried out — fencing, patrols, staff numbers — and poverty levels surrounding parks, their nearness to national borders and whether there is community engagement.” Chimes is currently planning a project that aims to separate these and other factors. In the meantime, Duthé believes that dehorning is a worthwhile tool of last course of action. “A rhino that is behaving a little bit strangely is better than a dead rhino.”
