2 . Yang He, a 64-year-old man from Yichang, Hubei, has observed the changes in finless porpoises (江豚) population with his camera for six years. As a(n) _________ of the finless porpoise, he has taken more than 100,000 photos of them so far.

Every day, Yang wakes up early and drives to the _________ of the Yangtze River. He waits _________ there for hours for finless porpoises to capture (捕捉) their _________ with his camera. Yang _________ finless porpoises very well. They are just like his children. As soon as one of them comes out from the water, he can tell which family it _________ .

The Yangtze finless porpoise is so _________ to the Yangtze River that any change in the health of its living environment can support or _________ its survival. “When I was a teenager, I could see many finless porpoises. I would often observe them _________ boats in the river,” Yang says. “But __________ human activities, finless porpoises became fewer.”

However, the situation has changed as __________ measures have been taken to protect the species. In 2017, Yang was __________ enough to take a photo of a finless porpoise after a long waiting. In 2019, he was able to take more photos, including images of the porpoises __________ fish near the riverbank.

Thanks to his camera, he once discovered and __________ a porpoise whose tail became entangled (缠住) with a rope. “I will make it my life’s work to __________ this amazing creature.” Yang says.

3 . Steller or Northern Sea Lions are sometimes confused with California Sea Lions but are much larger and lighter in color. Males may grow to 11 feet in length and weigh almost 2,500 pounds.     1     Steller Sea Lions are light brown to reddish-brown in color. They have a boxy, bear-like head and a very thick neck.

Stellers are not often seen in bays or rivers. Steller pups are born on offshore islands from mid-May to mid-July and weigh 35—50 pounds.     2     Then they spend roughly equal amounts of time hunting and nursing pups on land. Pups usually nurse for a year, but some in Alaska continue to nurse for up to three years. During the breeding season, males do not leave their territories.

    3     They hunt schooling fish, squid, rockfish, and occasionally salmon. In turn, they are hunted by killer whales, white sharks, and sea elephants.

The current population of Steller Sea Lions is about 40,000 along the entire Pacific coast. There is great concern about this species. The western Aleutian stock has dropped by 80 percent in the last 30 years. In 1997, the western stock in Alaska was listed as endangered.     4     However, researchers believe possibilities include a decline in specific species of fish they eat, competition with commercial fisheries in the Gulf of Alaska, and possible hunting by killer whales. Drowning, being caught in nets, and gunshots are other reasons for the Stellers’ decline. Stellers are protected under the Endangered Species Act and the Marine Mammal Protection Act.     5    

4 . A 36-year-old man is attempting to set a new record by rowing 5,000 miles solo from Hawaii to Australia while dedicating his journey to saving the planet.

Tez Steinberg, of Boulder, Colorado, plans to leave Hawaii on December 20 on his solo trip across the Pacific Ocean. Actually, it’s the second leg of an adventure that began in 2020 when he rowed solo for 71 days from Monterey, California, to Oahu, Hawaii.

Steinberg began to experience depression while he was in college. At the time, he found a solution by participating in endurance sports. “It helped me feel better,” he said. “But as I went farther and farther, pushing myself through marathons and triathlons, I discovered this belief in myself that I’m so much stronger than I thought I was.”

However, in 2016, his life took a big turn after the sudden death of his dad. The blow caused him to challenge himself even more by solo rowing across an ocean. After successfully completing the task without any prior professional experience, Steinberg realized he could use his story to inspire other people to believe in themselves and their potential to change and grow.

Recalling the first journey at sea, he said, “I was so surprised by how beautiful the ocean was, and also how much plastic I saw. So it was that realization at sea that led me to want to go back out again.” Inspired by his first expedition, Steinberg’s new mission is to focus on ocean conservation, and specifically ocean plastics. “All the plastic I saw at sea was just heartbreaking,” he said.

The upcoming voyage will be part of an attempt to break a Guinness World Record. Nevertheless, breaking records isn’t his priority. “Personally, although a world record is exciting, that’s not why I’m in it. The world record is fun for media attention, but through it we can get more donations, support and action for ocean plastics,” Steinberg said.

5 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.

In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.

Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.

Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.

This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

6 . The spotlight shines brightly on the dancers as they gracefully leap across the stage. But what sets this performance apart from others is not just the skill and grace of the dancers but the unique and meaningful use of recycled materials in their costumes and set design.

The famous Japanese ballet company, K-Ballet, recently showed their new production “Plastic”, which aims to raise awareness about the global plastic pollution crisis. The costumes worn by the dancers are made from used bubble wrap, the stage is surrounded by four massive walls constructed from recycled plastic bottles, and even the 100 umbrellas used in the performance were found abandoned in the streets of Tokyo.

The dancers, including guest star Julian MacKay, look like space-age creatures with hand-cleaned plastic bottles tied to their bodies as they dance on stage. MacKay, from the United States, notes that the issue of plastic waste “really hasn’t gotten that spotlight” in the dance world and believes that the performing arts can inspire people to take action.

The problem of plastic waste is a pressing one. According to the Organisation for Economic Cooperation and Development (OECD), plastic waste has doubled globally in the past 20 years, and only 9 percent of it is successfully recycled. The United Nations predicts that the volume of plastic entering the oceans will nearly triple (成为三倍) by 2040.

K-Ballet plans to keep its costumes and set design for at least a year with the hope of restaging the show and after that, the bottles will be recycled by Shirai, a waste management company. The chow’s experience and message moved audience members who attended the performance. Ayumi Kisaki, a 30-year-old actor, said, “It’s an issue I don’t usually think about. But these dancers highlighting the issue of plastic call me and all of us to find ways to recycle and reuse the plastic.”

South Koreans have enjoyed their first close-up look of new baby giant pandas at a name-revealing ceremony that is also     1     early celebration of the 100 days since the twins’ birth.

What to name the twin sisters was widely discussed among netizens after they were born on July 7 in theme park Everland. The names were     2     (ultimate) decided on through two public voting     3     (procedure). One is named Rui Bao, which means wise treasure, and the other is Hui Bao or shining treasure. Half a million panda lovers helped choose their names with a handful of lucky fans     4     (invite) to the ceremony. “They are even     5     (cute) in real life than they appear on screen,” said a college student in attendance.

The baby pandas,     6     have just begun teething and crawling, are very healthy. Everland has shared videos documenting the pandas’ growth online. The twins’ birth has gained 640,000 views since it     7     (upload). “This feels like a great opportunity to call for better     8     (preserve) of pandas,” said Donghee Chung, head of the park’s zoo. Chung noted that between 40% and 50% of panda births result     9     twins.

Everland said it would monitor the twins’ health     10     (determine) when the twins are ready to be open to the public.

8 . Scientists have been experimenting with playing sounds to plants since at least the 1960s, during which time they have been exposed to everything from Beethoven to Michael Jackson. Over the years, evidence that this sort of thing can have an effect has been growing. One paper, published in 2018, claimed that an Asian shrub known as the telegraph plant grew substantially larger leaves when exposed to 56 days of Buddhist music — but not if it was exposed to Western pop music or silence. Another, published last year, found that marigolds and sage plants exposed to the noise of traffic from a busy motorway suffered growth difficulty.

Plants have been evolving (进化) alongside the insects that eat them for hundreds of millions of years. With that in mind, Heidi Appel, a botanist now at the University of Houston, and Reginald Cocroft, a biologist at the University of Missouri, wondered if plants might be sensitive to the sounds made by the animals with which they most often interact. They recorded the vibrations made by certain species of caterpillars (毛毛虫) as they chewed on leaves. These vibrations are not powerful enough to produce sound waves in the air. But they are able to travel across leaves and branches, and even to neighbouring plants if their leaves touch.

They then exposed tobacco plant — the plant biologist’s version of the laboratory mouse — to the recorded vibrations while no caterpillars were actually present. Later, they put real caterpillars on the plants to see if exposure had led them to prepare for an insect attack. The results were striking. Leaves that had been exposed had significantly higher levels of defensive chemicals, making them much harder for the caterpillars to eat. Leaves that had not been exposed to vibrations showed no such response. Other sorts of vibration — caused by the wind, for instance, or other insects that do not eat leaves — had no effect.

“Now speakers with the right audio files are more often being used to warn crops to act when insects are detected but not yet widespread,” says Dr. Cocroft. “Unlike chemical pesticides, sound waves leave no dangerous chemicals.”

With more and more scientists saying we no longer have a climate problem but a climate emergency, the call for all hands to be part     1     the solution is bringing people of all     2    (age) to be ready. Leslie Wharton, spokesperson for Elders Climate Action(ECA), is in the midst of organizing a     3    (grow) number of “old hands” into a nationwide network of people who, instead of just talking, are getting together     4     (close) and taking action.

In 2014, after attending one of Al Gore’s Climate Reality training workshops, Paul Severance, a member of Elders Action Network(EAN), started ECA, which     5     (hold)its first in-person conference in September 2015 in Washington, D. C., with other climate activist groups. “That’s how I got     6     (involve),” Wharton says. “I was there in 2015 and I just felt such a community, such energy and support and focus, that I was just overwhelmed. At the end, I was given a form that asked if I would be willing to be     7    volunteer. I said yes.” Although most ECA members are in     8    (they) 50s through 80s and even 90s, some are as young as 18.

ECA’s mission is to reach out to older individuals and let them join, so they can use their expertise, experience and knowledge     9     (help) build a sustainable future. Those things can provide the support, encouragement, initiative     10     energy to get more and more people out there doing whatever they can do, right where they are.

10 . A team of leading environmental experts have warned that the current war on plastic is detracting from the bigger threats to the environment. In an article, they say that while plastic waste is an issue, its prominence in the general public’s concern for the environment is overshadowing greater threats, for example, climate change and biodiversity loss.

The team argue that much of the bad talk about plastic waste is based on data that is not always representative of the environments that have been sampled. The dislike of plastic associated with this could encourage the use of alternative materials with potentially harmful effects.

The authors warn that plastic pollution dominates the public’s concern for the environment and has been exploited politically, after capturing the attention of the world, for example, through the images of wildlife caught in plastic was alarmist headlines. They say small political gestures such as law banning cosmetic microplastics, taxing plastic bags, and financial rewards for using reusable containers, as well as the promotion of products as “green” for containing less plastic than alternatives, make people neglect other environmental problems that are not as noticeable as plastic pollution.

The article also highlights that plastic is not the only type of polluting materials, originating from human activity that pollutes the environment. Other examples include natural textile fibres such as cotton and wool, and brake-wear particles from vehicles — all of which are present in different places. The authors note that these materials are often much more abundant than microplastics and some are associated with “plastic alternatives” that are marketed as solutions to plastic pollution. The impacts of these materials are less well-known than plastic and microplastic pollution, yet they could have huge impacts.

The article states that solutions are likely to come from a greater focus on designing materials and products that can be recycled, that have their end-of-life, and that markets and facilities exist to recycle.
