3 . Students at St. Stanislaus High School in Mississippi are among the volunteers along US coasts raising oysters (牡蛎) to help restore, or repair weakened reefs (礁). Oyster reefs are an important part of coastal environments. Each oyster cleans 95 to 190 liters of water a day. The reefs provide living space for shrimp, crabs and fish. They also protect coastlines. In the states of Maryland, Virginia, Mississippi, and Alabama, now there are more than 1,000 oyster gardens. Most of them are in wire cages hanging from private ports.
Colin Wood, one student looking after the St. Stanislaus garden, said he was excited by the hands-on work. “I didn’t realize oysters had a big influence on the environment. And 50,000 to 55,000 adult oysters grown here each year go to reefs in Mobile Bay,” he said.
In the 1950s, an average of 37,400 tons of oysters were taken yearly from partly salty waters in the US. But US oyster harvests fell sharply in the 1990s. Data showed the cause of the drop could be overharvesting, pollution, pests and other problems. Then oyster gardening started.
Oyster gardening uses many of the same methods as farming. Farmers around the country grow oysters near the surface of water. Oysters develop much faster where the water holds more food they eat and enemies can be more easily removed. But the oysters are not being grown to be eaten. Oyster gardens get pulled from the water every seven to ten days. The time out of the water is used to clear out small animals, keep oysters from growing through the wires, and dry and clean off plant-life growing on the wires.
Bob Stokes, the director of the Galveston Bay Foundation in Texas, says, “Oyster gardening is as much about education as it is restoration.”

6 . Do you know that about 71 percent of our planet is covered by the ocean (海洋) ?
Without oceans, life couldn’t exist. Scientists don’t know the exact number, but they think that oceans are home to 50 percent to 80 percent of all species on Earth, from large whales to tiny plankton. Oceans absorb carbon dioxide and give out oxygen (氧气).

7 . Nirvaan Agarwal found out early how powerful a kid’s voice can be. He was taking part in a protest against the mistreatment of animals at a local circus (马戏团) when he was 3 years old. “I passed out almost half copies of brochures,” Nirvaan told TIME for Kids. “People kept taking them from me because I was a little kid.”
Since then, Nirvaan, now 12, has been speaking out on a range of issues affecting animals, from their use in the fur (毛皮) industry to horse racing. That commitment shows in his personal life, too, He’s a vegan, which means he doesn’t eat food that comes from animals. He says, “It’s important to make a voice for animals because they can’t speak for themselves.” In the meantime, Nirvaan encourages other kids who care about animals to take action. “It’s never too early to help animals,” he says.
In 2022, he spoke before county officials in his hometown of Edison, New Jersey, relaying animal advocates’ concerns about the Johnson Park zoo, in Piscataway, which was always hit by flood, threatening the animals’ life, Nirvaan got results, Months later, it was finally closed and the animals were moved to shelters, Later that year, Nirvaan was recognized for his work by the animal-rights organization PETA Kids. He was named one of its Kids’ All-Star for Animals. The honor gave him a new viewpoint on his duty. “It makes me feel like I have the power to do something,” he says. “I feel like I can change the world.”
Even with all of his accomplishments, Nirvaan has big plans for the future, He says, “Ending the mistreatment of animals happens one step at a time. You can slowly break down the pillars (柱子) of a structure. Eventually, when you break down all of those pillars, the whole structure falls.” He hopes to be a chef and create vegan recipes someday.

8 . Any parent of growing teenagers knows their kids’ appetite (食欲) can be extremely large. Now, imagine having a young dinosaur checking the fridge. The out size appetites of growing dinosaurs reshaped food chains in their environment and crowded out other carnivores (食肉动物), according to a new study.
Most groups of animals have many small-sized species, somewhat fewer medium-sized species and the fewest large-sized species. However, the extinct dinosaurs—especially carnivores had plenty of species no bigger than modern-day chickens and also many extremely big species, but few medium-sized ones.
Scientists wondered whether teen dinosaurs crowded out medium-sized adults by taking advantage of the habitats and food sources those species might have taken. To test the idea, Katlin Schroeder, a Ph. D. student at the University of New Mexico (UNM), combed a global collection of data to determine the size of more than 550 dinosaur species in 43 ancient ecosystems.
“In most communities, plant-eating dinosaurs were in multifarious sizes. But carnivores were completely different,” Schroeder says. Plant-eating dinosaurs came in a range of sizes, while carnivorous dinosaurs between 100 and 1, 000 kilograms were quite rare. “The size of the carnivorous dinosaur is surprising. It’s as if you went to the savanna, a large flat area of grassy land, and saw nothing in size between a small fox and a lion,” Schroeder says. “Patterns in all the dinosaur communities studied are very similar. We saw the gap in species’ sizes for years, but never measured it.”
Schroeder and paleontologists Eelisa Smith of UNM and Kathleen Lyons of the University of Nebraska, Lincoln, modeled the role that young carnivorous dinosaurs might have played in ecosystems. “If the teen dinosaurs are really using up this space, how many of them would you expect?” Smith says. Their study showed that “the teenagers fill the gap,” she says. “If you fill them in, then you get a community that looks like what you’d expect.”
“The effect maybe stronger in meat eaters because each carnivorous dinosaur species hatched (孵化) from small eggs; then they grew very quickly. They had to change diets and hunting methods to adapt to their new sizes and compete with a range of other species along the way,” Erickson, another scientist, says.
“The study’s stress on how animals’ niches (生态位) can change as they grow offers fresh understandings,” says Mike Benton, a scientist at the University of Bristol.

9 . For eight years, Handshouse Studio has worked to create toys for Emily and Ruth, two Asian elephants at the Buttonwood Park Zoo in New Bedford.
The founders of the organization, Rick and Laura Brown, are both art teachers and created the “Toys for Elephants” program to challenge their students to make toys for Emily and Ruth and raise the quality of their lives at the zoo. Emily and Ruth were saved from a failed circus (马戏团) in Asia and were badly treated in their youth.
In the spring, the art students make the toys out of wood and other materials (材料). At the end of the semester, the class sends them to Emily and Ruth at the zoo.
This year, the Norwell Fire Department gave away old fire hoses (消防水龙带) to the class. “It’s interesting what use people find in old hoses,” Fire Chief Andrew Reardon said. “To create toys for elephants was certainly a first.” Reardon said they were happy to give Handshouse the old hose to make toys for the elephants and that it was a special chance to be a part of that. “It’s not every day you get to help make toys for elephants,” Reardon said.
Once at the zoo, the students set up their toys around the empty elephant house and quickly leave so Emily and Ruth may come in to play with their new toys. “The students have really embraced this and they really want to have a part to play in solving the serious problem of keeping animals in captivity (圈养),” Rick said.
Handshouse Studio decided to work with other zoos and art and design organizations around the world with the “Toys for Elephants” program. Already, they have been getting calls from all over the world, including New Zealand, Germany and Thailand.

10 . Animals, including humans, feel sound as well as hear it, and some of the most meaningful communication happens at frequencies (频率) that people can’t hear. Elephants, for example, use these low-frequency sounds to, among other things, find family or a mate across long distances. Whales do it, too.
But you don’t have to weigh a ton to make a sound. In fact, you don’t have to be bigger than a pea. Consider, for example, the tree-hopper, a curious little animal that lives on the stems (茎) of the leaves. University of Missouri biologist Rex Cocroft has spent much of his time listening closely to tree-hoppers with his team.
The team discovers that all the sounds being heard from tree-hoppers are produced by males. They do it by vibrating (振动) their abdomens (腹部) to make a wide variety of strange sounds. There is almost no airborne sound produced with these vibrational sounds. Cocroft explained, “If a tree-hopper were to stand on your finger and produce a sound, you would feel the vibration but hear no sound.”
They showed that some sounds, not surprisingly, seem to be aimed at attracting females. And some are aimed at other males.
Cocroft explained, “When two males meet each other, or when they are mate-searching on a branch, we’re hearing ‘purring, bdddddrrrr…’ sounds that males give.” Normally, a person couldn’t hear any of this, because the sound travels along the stem, inside it. And that’s how other tree-hoppers detect it.
Cocroft said tree-hoppers have very sensitive legs. And they stand around on stems, which are good at spreading vibrations. So they just use what nature gives them to communicate with each other.
“They have so many different forms of social behavior and grouping,” Cocroft explained. “And once there are animals living in groups, then there will be all sorts of interesting possibilities for communication.”
