1 . The Atacama Desert in northern Chile stretches from the Pacific to the Andes across an expanse of red-orange rock mountains and peaks. It’s a dream destination for tourists. But the Atacama Desert is also one of the world’s fast-growing dumps (垃圾场) of abandoned clothes. The scene in northern Chile has been shown in one online video-large amounts of abandoned clothes stretch as far as the eye can see.

Chile is home to one of South America’s largest duty-free ports-located in the coastal city of Iquique. The duty-free port was established in 1975 to help generate jobs and improve local economy. As fast fashion exploded, so did imports. Millions of tons of clothes arrive annually from all over the world.

“The free zone was a ’true transformation’ for the city’s residents,” says Bernardo Guerrero, a sociologist that studies Iquique’s history and culture. “They suddenly had access to things they could never have imagined.” Clothing began washing in and out of Iquique like waves as global fashions changed. Guerrero recalls a time when almost everybody in the city wore the same style of puffer jacket.

The free zone has also developed into a sorting site for abandoned clothes. Mehmet Yildiz, who operates a clothing import business, brings in clothes from the United States and Europe. Once the clothes reach Iquique, workers separate them into four categories according to quality. Yildiz then exports the best to other countries for resale. Clothing that the importers don’t want will be delivered a few miles outside Alto Hospicio, where it goes through another cycle of sorting and resale in street markets. Clothing that doesn’t sell at the market is sent to the desert, and much of it is made from materials that won’t biodegrade (生物降解).

As helpful as resale markets might have been in an earlier era, they’ve been flooded with the large amounts of the mounting discards. New efforts, large and small, are under way to deal with clothing waste, and attention to the mess in the desert may inspire additional projects.

Using animals to test drugs intended for humans is controversial, with critics arguing there are other ways to ensure new medicines are safe and effective. But the scientists who carry out the research say animal studies remain necessary. Statistics indicate that in the UK around three million mice are being used for research and tens of millions worldwide.

Despite the difference in appearances, the genetic similarities with humans are     1    . The mouse genome (基因组) shares over 95% of its genes with humans. The animal acts as a “model”, genetically     2     to develop a human disease. But the use of mice, like any animal, in research is criticized by some.

Animal Defenders International (ADI) is one of the groups that campaigns for an end to the use of animals in research. “We would argue that it is extremely outdated, and not very good science for humans,” says Fleur Dawes of ADI. Ms. Dawes believes the suffering that the animals go through does not legalize their     3     to science and medicine for humans.” There is a big problem with that because there are huge differences between the species. And even though there are similarities with humans and mice, they react very differently to each other when experimented on. So what works in one animal is not an indication that that is how things work in other animals.”

However, Dr. Wells from Mary Lyon Centre (MLC) says they are constantly trying to     4     the process to reduce the suffering of mice.” If it’s a procedure where you can anaesthetize (麻醉) the mice, then you do it to reduce their stress. And if there is a (n)     5     method that doesn’t involve mice, you are not legally and normally allowed to do the procedure.”

If we     6     animal research, are there alternatives? Dr. Wells says, “There is a massive field     7     on alternatives, and we are very supportive of that field and we always keep track of what is going on in that field, because maybe we can replace one of our models. “Those alternatives include chips on human organs to study their function, micro-dosing treatments in humans and     8     models.” Lots of people say that there is a computer now to model what is going to happen in diseases,” Dr. Wells adds, “But we still don’t know enough to program those computers with     9     knowledge to be able to model what’s happening in every disease.”

Fleur Dawes agrees one alternative is not enough. But she says, “By combining the different alternatives, you can actually get a much better picture that is of much better     10     to humans.”

“A decade-long moratorium (中止) on fishing was imposed on the country's longest river in 2021     1     the aim of restoring its ecological health. After three years, the fish population in the river has recovered obviously, but the moratorium still faces constant threats from illegal fishing,”Tang Renjian, minister of agriculture and rural affairs, said at a news conference.

In     2     (respond) to that, Tang said, “Authorities will step up nighttime surveillance (监视) as well as patrols near river sections close to provincial borders. Relying on automatic and     3     (intelligence) monitoring methods, we are strengthening round-the-clock monitoring and supervision of critical water areas.”

Ma Youxiang, a vice-minister of agriculture and rural affairs, told the news conference,     4     it has increased by a quarter since 2021,     5     total fish population in the Yangtze is only     6     (slight) more than a third of the preindustrial (工业化前的) level. To restore fish populations is a long task. Tang described the ban as a long-term, complex and hard historical task closely     7     (link) to the Chinese nation's sustainable development.

“    8     you may see, the current state of the Yangtze can     9     (regard) as being in the early stages of recovery from a serious illness after decades of overfishing and pollution,” Tang said.

Ministry of Public Security data show it has solved more than 20,000 cases     10     (involve) violations of the ban since 2021. Over that period, illegal fishing in the main waterways of the Yangtze has decreased by almost a third, and less than 10 percent involves more destructive organized crimes.

5 . For uncounted generations, trillions of coral polyps (珊瑚虫) have lived and died, leaving behind a material called limestone. Throughout History, limestone was used to construct the Great Pyramid of Egypt, as well as many churches and castles.       1    . We can call them reefs (礁体). They can be even larger in scale than the most impressive buildings and structures made by humans.

    2    

Indeed, a living coral reef is remarkable, a “city beneath the sea” filled with a rich variety of life. Most coral reefs can be found in warm, shallow oceans. They occupy just a small part of the ocean floor, but host 25 percent of all ocean life. Each reef is full of colorful fish as well as coral that forms wonderful patterns. In addition to their beauty, the reefs are an important food source for fish, and for. humans.

Threats to coral reefs

    3    . For example, reefs can be damaged when the coral is taken for use in building materials or jewelry-making. Illegal fishing methods also harm reefs. These methods can help fishermen get a good catch, but their negative effects on the reefs are significant. Blast fishing involves setting off bombs in the water to kill as many fish as possible.     4     In addition, global warming has caused many reefs to become sick. A 2018 UN Report predicted that up to 99 percent of the world’s coral reefs may decline if global warming continues.   

Reasons for hope

These threats to coral reefs are very serious, but there is reason to hope that they will survive. If we take steps toward coral reef conservation, it is likely that these tiny creatures — which survived natural threats for millions of years — will be able to rebuild. As conservationist Robert Richmond says, “    5    . ”

6 . Have you ever paid attention to the color of the airplane seats? They’re almost always blue and there are very few exceptions to this rule. Some people think it reminds us of the sky. But the explanation isn’t that simple!

It is calming.

Color psychology plays an important role in selecting the fabric for airplane seats. “The idea is to help passengers feel at home, with relaxing colors and restful designs,” explained Shelly Zundell in a Boeing press release.     1     Blue is a calming color that suggests peace, calmness, and relaxation.

    2    

In a study reported by Popular Science, 48 percent of participants thought soda in a blue glass was more thirst-quenching (解渴的) than that served in glasses of other colors, probably because they connected blue with cold. Colors such as red and orange can make people feel warmer. Although it’s not unheard of, red is a less common color for airplane seats.     3    

It is a universally well-liked color.

    4     It’s a universal color that’s appealing to most. This is also the same reason why many brands have blue logos. People universally connect the color with positive things — such as clean water and blue skies — so they tend to like it. Across ages and across cultures, it’s the world’s favorite color.

The right shade hides stains (污渍) well.

Dark blue seats are also just practical. Imagine how many people sit in them per day.     5    

Darker shades are better at hiding stains and don’t show their wear as easily. Those dark blue seats will look fresher and newer for longer.

7 . The sun near the equator is never-ceasing, bearing down as I lead Elaine, a dark brown horse, through thick bushes. It’s been a long day on horseback. My legs ache and our camp signals across a ridge of ancient folding hills in the Lolldaiga Range of northern Kenya, a mosaic (马赛克) of twisted landscapes and communities.

Suddenly Elaine’s ears flick into alert, and the muscles of her body tense beneath me. Our guide Nicholus stretches out a lean arm toward a bush just meters away. My eyes focus, trying my best to see what the others already have: two amber balls glowing from a shadowed form. It’s a young lion, quick and strong, in the middle of the high grass.

A wild silence hangs between us.

Without the defensive hunting vehicle, I feel completely exposed. Peering into the bush, I’m suspended between wonder and terror, the distance between myself and the Savannah’s most notorious hunter unbelievably small. Usually, I’m the one tracking the lion, camera in hand. Now, the lion shifts in my consciousness from object to subject. I shift, too, strongly aware of the soft flesh of my own body.

Nicholus nods his head in the other direction, a safer distance away. He points to shallow holes in the dust. “Look, this is a big lion, and these are young ones, some cubs,” he says. “Probably a mother.” Pawprints marked the earth, each telling the story of more lions, moving in different directions.

It was time to go.

Horseback safaris are still the most immersive way to view wildlife in Kenya. To journey on horseback is to break down the walls — meant to protect, but also to separate us from the natural world. And as we’re absorbed in the thrill of the experience, we’re vividly reminded of the importance of protecting these wild spaces.

Out here your horse is your translator, responding to the low hiss of a leopard, the soft scent of an elephant herd, the cool morning breeze descending from Mount Kenya’s glacial peaks. Your job is to learn how to listen.

8 . A woman in a cap wanders calmly along. Except for the lava (熔岩) erupting behind her, she could be walking in the park. The woman turns to watch the molten rock flow for a moment then walks calmly toward the camera. The footage(镜头) is from Werner Herzog’s book to volcanoes and volcano hunters, Into the Inferno, and the woman pictured is perhaps one of the most important volcanologists of all time, Katia Krafft.

Born in France, in 1942, Katia developed an interest in volcanoes at an early age. Later, she met Maurice Krafft. The pair bonded over their shared love of volcanoes before marrying in 1970. The Kraffts wrote about 20 books on volcanoes across the globe.

Katia and her husband made great progress in educating the general public in volcanology. Their footage had more than scientific value. For instance, when Mount Pinatubo in the Philippines began to show signs of an eruption in 1991, the Kraffts were able to present Philippine President Cory Aquino with video footage of the effects of the 1985 eruption of Nevado del Ruiz in Colombia, asking him to call for an evacuation of those in the danger zone.

In 1969, Katia was awarded the prize of the Vocation Foundation for her work on active volcanic sites.

The couple lost their lives, along with more than 40 others during the eruption of Mount Unzen in Japan on June 3.1991. when they were caught in a flow of rock, gas and ash moving at speeds of over 100 miles per hour, with temperatures of more than 800 degrees Fahrenheit. Katia was 49; Maurice, 45.

Katia’s impact on volcanology has reached far beyond her death and has encouraged many young women to study our restless planet. “Katia Krafft is definitely the reason why I’m doing this job,” says Carla Tiraboschi, a postdoctoral researcher at the University of Minster, Germany. Carla first saw Katia in a documentary when she was just six or seven years old and has been crazy about volcanoes ever since.

10 . Beneath the blue waters of Trinidad and Tobago, plastic pollution is causing serious damage to marine ecosystems. Every year, over 88,600 tonnes of plastic waste is deposited(沉积)into the ocean around the Caribbean nation, harming marine life and impacting human health.

A new app is aiming to help young people in Trinidad and Tobago, along with other small island developing states, battle against the damage done by plastic pollution. Called Tide Turners, the app was developed by the United Nations Environment Programme with the help of young people. It challenges users to record their plastics consumption and develop an action plan to reduce their use of plastics. It also encourages young people to switch to reusable products and go plastic-free where possible: lifestyle changes that experts say can help stop the flow of plastic into the world’s oceans.

Reducing plastic pollution will take a joint effort from governments, businesses and, especially, youth. Children account for around 30 percent of the population in small island developing states in the Caribbean.

To tackle the plastic pollution challenge, the new app builds on UNEP’s Tide Turners Plastic Challenge Badge, which has so far engaged more than 500,000 young people in youth groups. Along with calling on youth to use less plastic, it encourages them to start campaigns and raise awareness about the dangers of plastic pollution.

In Trinidad and Tobago, Sarah Sobrian, who tested an early version of the app and advised on its development, is keen to get started. “The Tide Turners app is an incredible tool that educates and empowers us to change the situation we face,” she says. “I am incredibly eager to be a part of this and share this experience with those in my life. With this app, we can and will work together to create the impact that we have long wanted to see.”
