1 . Conservation scientist Kim Williams-Guillen was trying her best to come up with a way to save endangered sea turtles (海龟) from egg thieves when she had an “aha” moment: If she placed a fake (假的) egg containing a GPS tracker in the reptiles’ nests, she might be able to track the thieves.
Williams-Guillen found a flexible plastic material to mimic (仿造) the shell of real eggs. She and colleagues then used a 3D printer to produce the fakes of the same size, weight, and texture and put the smallest GPS tracking devices inside each. The researchers then went to four Costa Rican beaches, where green sea turtle come ashore to make their nests. As mothers laid their eggs under cover of night, the researchers slipped a fake egg into each nest. Once the fakes are covered in sand and mix with the real eggs, it’s very difficult to tell the difference between the two.
Of the 101 fake eggs, 25 were taken by thieves. The farthest moving egg traveled 137 kilometers inland. The fake egg sent its final signal the next day from a residential property, suggesting that the research team had tracked the eggs through “all of the players in the entire chain.”
By understanding that chain, Williams-Guillen says researchers can identify trading hot spots. She emphasizes that the tracker is not a way to catch local thieves, many of them living in poverty, but a tool to better understand their routes, which could help them and eventually law enforcement (执法部门) identify larger players in the chain.
In the meantime, Williams-Guillen and her colleagues are working to get their fake eggs to other sea turtle conservation organizations. Ultimately, though, scientists and nonprofits are going to engage communities with local outreach and education programs to save sea turtles. She says, “The real meat and potatoes of conservation isn’t going to come from deploying (布署) eggs.”

F.It will aid with your insurance company if anything needs to be replaced. |
G.These dangerous storms can bring damage to your home and belongings. |
4 . When Malaika Vaz was a kid, living in Goa, India, she was constantly surrounded by nature. Among her childhood experiences, she recalls journeys to the Arctic and Antarctic, climbing mountains, diving, and windsurfing.
At some point in her late teens, Vaz realized adventure didn’t really mean anything if there wasn’t an intention to protect the natural spaces we were exploring in. Motivated by her passion for filmmaking, she began to seek a way that would both satisfy her appetite for adventure and allow her to advocate the protection of the species and ecosystems she interacted with.
Today Vaz wears many hats in the filmmaking world, as a documentary director, producer, and presenter. After falling in love with manta rays (蝠鲼), she discovered they were being hunted illegally and started to dress herself as a seafood trader to get as close as possible to the issue. She traced sellers to figure out why the threatened species were being killed. She shared the shocking details in Peng Yu Sai, her Green Oscar-nominated film on the matter.
The subjects that grab her attention, Vaz admits, run the gamut. When she was asked to define her focus, she replied that she preferred variety. She always argues that the issues she looks into are more interrelated than they may initially appear. “I think that it’s exciting to dive into the different aspects of environmental stories,” she says.
Her work doesn’t stop at recording important stories; she also ensures the message is heard. From Vaz’s viewpoint, real improvement in planetary protection lies in the hands of each of us rather than just those of several environmentalists. “If you’re an engineer and you care about the natural world, you can change the kind of construction materials you use. If you’re a teacher loving nature, you can bring that into the learning for your class.” she says.
As a filmmaker, Vaz believes it’s important to figure out ways that attract the audience who can push for the protection of the natural world.

One morning on my way to school, noticed an elderly woman dressed in a yellow vest (马 甲)carrying a garbage bag and one of those rubbish claws (爪形器具)."What's that lady doing?" I asked mum. "Vest Lady. She just picks up rubbish around here for fun," mum said. "Why would someone think picking up rubbish looking like a construction worker is fun?" I puzzled.
For several years I'd witness this mysterious Vest Lady—rain or shine — on my way to school. I had thought she was crazy for picking up rubbish. Eventually I smiled and waved at her each time I saw her. Later, I moved to high school. The time I saw rubbish here and there I felt really annoyed. Then I'd think, "Why isn't anyone picking up this rubbish? People are so inconsiderate I" However, shortly after, I realized picking up the rubbish was not someone ease's problem.
Now I couldn't walk past litter without feeling guilty. I volunteered to clean up rubbish around our school. Strange as it might sound, picking up litter was kind of a thrill for me! In fact, I was so determined that for my 17th birthday I bought myself a rubbish claw, reusable gloves and a reflective safety yellow vest with my own name on it.
During my first attempt in my stylish equipment, met with unfriendly looks from others as if I were a criminal doing community service. One day,I had an epiphany(顿悟):"I'm acting just like Vest Lady!"
But there was too much rubbish around, cigarette ends littered about, cans rolling on the street,pieces of paper hidden in the grass and plastic. alone was too weak J How would I get more volunteers involved in rubbish removal? A smart idea flashed into my mind.

6 . Before the year has even come to a close, climate experts are certain that 2023 will be the hottest year in recorded history.
On Dec. 6, the Copernicus Climate Change Service (C3S) — part of the European Union's space program — revealed that this year's average global temperatures have been 2.6℉ (1.46°C ) higher than temperatures in preindustrial times and 0.2°F (0.13°C) higher than January to November in 2016. These “extraordinary” temperatures mean that 2023will be “the warmest year in recorded history,” C3S deputy director Samantha Burgess said in a statement.
The researchers note that this year's record heat was partly caused by the latest El Nino event — a phenomenon where warmer water near the equator triggers warmer global air temperatures — that began in June. Some other experts have suggested that the January2022 eruption of Tonga's underwater volcano, which pumped record levels of water vapor into the atmosphere, may also be partly responsible.
Despite these factors, the major cause of climbing temperatures is global warming caused by runaway greenhouse gas emissions, which, noted in a C3S statement, have trapped more than 25 billion atomic bombs' worth of energy in our atmosphere over the last 50 years. And still worse, the global carbon emissions have reached a new high this year, according to scientists at the United Nations Climate Change Conference of the Parties (COP28) On Dec 4.
The effects of global warming are becoming more obvious. In 2023, research revealed that climate change is causing major US cities to sink and more than half of the world's largest lakes and reservoirs to shrink. Studies also predicted that the Gulf Stream, which plays a vital role in ocean circulation, could collapse by as early as 2025, and that rising sea levels could swamp the U S coastline by 2050.
However, scientists say that we still have time to prevent further disaster. Leading climate change expert Michael Mann, from the University of Pennsylvania, recently wrote that “we can still stop the worst effects of climate change” if we stop emitting greenhouse gases as soon as possible.

7 . The students stand on a pier (码头) over the Harlem River in New York City. They stare down into the brown water. Their teacher, Mr. Rodman, pulls a long rope out of the river. Fastened to the end of the rope is a metal cage and inside are oysters (牡蛎). Taking turns, the students measure all the oysters, and then compare notes. The biggest oyster is over 2 inches long, much bigger than a healthy size for its age! They also measure the level of oxygen. As more oysters grow, the water should become clearer and hold more oxygen. Also, other animals should move in.
Oysters are soft-bodied animals, and share the underwater community with plants, fish, and other life. They are food for crabs and other animals. As new oysters grow, they attach their shells to older ones,forming big reefs with many small spaces where other animals live. Oysters eat algae (藻类). If algae grow too fast,they can decrease oxygen from the water-and even fish need oxygen to breathe!
But what happened to the oysters 100years ago in New York Harbor? Before then, lots of oysters lived in these waters. They were shipped to restaurants around the world. By the early 1900s, people were eating them faster than they could grow. Pollution was pouring into the waters. The harbor became seriously polluted. Since the 1970s, new laws have helped reduce poisonous waste. Some fish started to swim through again. But oysters were still missing-until recently.
The Billion Oyster Project began in 2014 to help bring oysters back to New York Harbor. The project has recruited (招募) more than 6,500 students at more than 100 middle schools and high schools to help grow, distribute, and study the oysters.
Finally, the students put the oysters back in the cage. Mr. Rodman lowers the cage into the river. In a few months, they will check the cage again. When the oysters are big enough, they will be moved to join a healthy reef in the middle of the harbor.

9 . Leave-No-Trace Camping
For those of us who love spending time in the great outdoors, wild spaces are very special. These are places we visit to recharge, or to fill our hearts with natural beauty.
Its principles are to treat the wilderness the way a decent visitor would and leave everything just as you found it, with no evidence that you passed through.
You can carry out these ideals in a number of ways. Begin by packing out all your litter. Whenever you go camping, take an empty trash bag with you and put all garbage into the bag. In addition, try not to damage vegetation.
It’s also important that you should not take things away from the wilderness. Rocks, plants, flowers and seashells are all part of the natural landscape.
Leave-No-Trace camping is about being respectful and thoughtful. It’s about honoring the natural world and the creatures that live in it. If you love seeing an untouched mountain stream or a lovely field of wildflowers, then you’ve already taken the first step.
A.This means not stepping into a wild animal’s space. |
B.This is also called “low impact” or “no impact” camping. |
C.Once taken away, they won’t be there for others to enjoy. |
D.An increasing number of people take up camping in the wilderness. |
E.When you put up your tent, try to find a place that’s already bare of plants. |
F.We hate to see them littered with rubbish or any reminders of previous visitors. |
G.Follow these basic practices and you can be models of the Leave-No-Trace philosophy. |
10 . Introduced species have a bad reputation. It has been believed that the species mix in a particular place should remain as unchanged as possible. But this is just an opinion. Other opinions are possible. A study published recently by Dov Sax of Brown University, thus asks how the benefits of introduced species might be better assessed, so that opinions can be more informed. Specifically, he identifies several aspects for that.
Initially, whether introduced species provide direct human advantage is taken into account. Dr. Sax and his colleagues ignored crops, since their benefits are obvious. But they included transplanted grass species that have gone wild,yet provide grazing(牧草)for domestic animals, and introduced forest trees that produce wood for construction.
Another factor is their possible benefit to the ecosystem into which the introduction has happened. Such introduction is sometimes made to reduce the risk of a localised species becoming extinct. Pyne’s ground plum(李子),native to a handful of sites in the central basins of Tennessee but now transplanted to others, falls into this category.
The last value is experienced on an emotional rather than a practical level. Lots of people feel good about native wildlife, which is generally the main motive for its conservation. But that feel-good factor can extend to introduced species as well. Such value can cut both ways, however. For example, ring-necked parakeets, an Asian and African species, have been spreading through Britain for several decades. Some find them a colourful addition to the local wildlife, others a noisy competitor for native birds.
In light of their analysis, Dr. Sax and his team therefore suggest that researchers studying introduced species should in future create a clear distinction in their studies between changes that have happened and judgments about the value of those changes. In addition, when making those judgments, they should acknowledge all types of values, rather than focusing narrowly on one or two of them.
That done, many species will surely still be accused of possible damage. But others, badly thought of in the past, may not.
