On a hot September afternoon, Peter and his friend Isabel were on their way to the library. When they passed by Tubman park, Isabel suggested cutting through it to get to the library. As they entered the park, the sight of the swings (秋千) and the merry-go-round brought back a flood of memories of their childhood spent there. But now everything looked so old, sad, and dirty. Litter lay on the ground next to an overflowing trash bin. There were still young schoolchildren playing there but they had to avoid the trash that littered the playground. A little boy told them that the city took the other trash cans away and the remaining one never got emptied often.
As they headed toward the library, the two high school students wrinkled their forehead. In the library, they encountered Mrs. Evans, their kind-hearted fifth-grade teacher, retired yet still passionate. Mrs. Evans listened as Isabel and Peter eagerly explained what they’d seen. Finally, she recommended them to go to the City Hall to voice their concerns.
The next day, Isabel and Peter went into the building of the City Hall but were met with an impatient officer. They were informed that the city couldn’t help with their problem due to a tight budget. Discouraged, they left and turned to Mrs. Evans for help.
Under her guidance, they decided to ask Go Green, a non-profit organization whose goal is to protect the environment, for help. “This group is good at raising money for projects just like yours, ” said Mrs. Evans. She promised to arrange them to present their ideas to Go Green. Hearing this, their face lit up.
Two main tasks remained ahead: researching ways to clean up the park and preparing a convincing presentation. As Isabel was good at researching while Peter always had a talent for speaking, they cooperated quite well. Isabel learned from a science magazine that a new type of trash bin can squeeze the trash down without being emptied often, which saves time, money, and energy. Based on this, Peter practiced his presentation over and over again.

The rechargeable lithium-ion (锂离子) battery market is worth more than ＄50 billion. Lithium-ion batteries, whose demand continues to go up day by day, are used in a wide range of electronic devices. They are made of four main components, and cathode (阴极) is one of them. The cathode’s active material type is what determines the capacity of a battery.
A recent study, led by Wang Yan, a material scientist of Worcester Polytechnic Institute, finds that lithium-ion batteries made with recycled cathodes work better than those with new cathodes.
“The battery industry is expected to grow sharply in the next decade. This high demand has led companies to go to extremes, like increasing deep-sea mining, to gain access to the minerals used in lithium-ion batteries,” Wang said. “Mining minerals will have environmental impacts. Recycling spent lithium-ion batteries offers a way out.”
But until now, the prospect of using recycled materials in lithium-ion batteries has some manufacturers (制造商) worrying that it could impact performance. Thus, lithium-ion batteries are still not widely recycled. Aware of decreasing resources and environmental impact, Wang and other researchers set out to find a way to make recycling lithium-ion batteries economically practical. Through experiments, they could recover more than 90% of the key metals from spent batteries. These recovered metals became the basis of the new recycled battery’s cathode’s active material.
In tests between Wang’s team’s recycled batteries and brand-new batteries of the same composition, the recycled batteries outperform the new ones in their ability to maintain capacity. It took 11,600 charge cycles for recycled cathode batteries to lose 30 percent of their original capacity. That was about 50 percent better than the 7,600 observed cycles for new cathode batteries, the team reported. Those thousands of extra cycles could translate into years of better battery performance, even after repeated use and recharging.

5 . The scientists who re-engineered the plastic-eating enzyme(酶) PETase have now created a new enzyme called “cocktail” , which can digest plastic up to six times faster.
PETase breaks down PET back into its building blocks, creating an opportunity to recycle plastic and reduce plastic pollution. PET is the most common thermoplastic(热塑性塑料) used to make single-use drinks bottles, which takes hundreds of years to break down in the environment, but PETase can shorten this time to days. The initial discovery set up the prospect of a revolution in plastic recycling, creating a potential low-energy solution to tackle plastic waste.
Now, the same trans-Atlantic team have combined PETase and its “partner”, a second enzyme called MHETase, to generate much bigger improvements: simply mixing PETase with MHETase doubled the speed of PET breakdown, and engineering a connection between the two enzymes to create a “super-enzyme”, increased this activity by a further three times.
The team was co-led by the scientists who engineered PETase, Professor John McGeehan and Dr Gregg Beckham. Professor McGeehan said: “Gregg and I were chatting about how PETase attacks the surface of the plastics and MHETase chops things up further, so it seemed natural to see if we could use them together. Our first experiments showed that they did work better together, so we decided to physically link them. It took a great deal of work, but it was worth the effort — we were delighted to see that our new enzyme is up to three times faster than the separate enzymes.”
The original PETase enzyme discovery indicated the first hope that a solution to the global plastic pollution problem might be within grasp, though PETase alone is not yet fast enough to handle the tons of PET bottles. Combining it with a second enzyme, and finding together they work even faster, means another leap forward has been taken towards finding a solution to plastic waste. PETase and the new combined MHETase-PETase both work by digesting PET plastic. This allows for plastics to be made and reused endlessly, reducing our reliance on fossil(化石) resources.

6 . More than 45,000 years ago, by the shore of present-day Tasmania, a local person picked up a large piece of thick, dark brown seaweed. And he realized that this giant piece of seaweed could be used to make a watertight(不透水的) bag. And 45,000 years later on mainland Australia, people are again turning to seaweed to solve pressing problems. Today, it is used to address the world’s climate crisis.
Winberg, a marine ecologist, has spent decades studying seaweed. She believes seaweed’s fast growth rate and ability to absorb vast amounts of carbon dioxide can help fight climate change, clean the oceans, and change the way we farm, not just in the oceans but also on land.
Realizing seaweed’s potential as a climate solution, Winberg opened Australia’s first land-based, commercial seaweed farm in 2013. On her farm Winberg produces seaweed juices that are used in food, and medicines. Like plants on land, seaweed absorbs CO2 and grows biomass(生物量). Coastal marine systems can absorb carbon at rates up to 50 times greater than forests on land. Globally, seaweeds are thought to sequester nearly 200 million tons of CO2 every year — as much as New York States annual emissions. And when the seaweed dies, much of the carbon locked up in its tissues is transported to deep oceans.
The potential for seaweed doesn’t stop in the oceans. Winberg has found there are benefits on land, too. She believes that seaweed farming offers “huge potential” to not only address the climate crisis, but also feed a growing population in a sustainable way. According to Winberg, one hectare of a seaweed farm can produce more protein than the same amount of land used for cattle. “We’re sitting on undiscovered, renewable, sustainable resources,” she says.
In the thousands of years of human experimentation with seaweed, the scale of the challenges that seaweed can help solve has grown largely. But some things are still the same. To the Aboriginal Australians living in Tasmania who first discovered some of seaweed’s uses, it might have seemed like a wonder material as they made watertight bags out of it. To seaweed experts like Winberg today, this old idea is still ringing true.

7 . How to Reduce Gift Wrap Waste
Wrapping paper may have “paper” in its name, but that doesn’t automatically mean it can be recycled.
Reuse what you have.
Use different materials.
Ask for better paper. Shops store what customers want, and recyclability should be a top priority, so let that be known when you’re out shopping. As explained by Simon Ellin, CEO of the Recycling Association, a trade body that represents about 90 waste management companies and paper merchants in the United Kingdom, “It’s a campaign we’ve been on all year — do you really need to design a non-paper wrapping paper? Make paper with recycling in mind!”
| A．Try zero waste. |
| B．Shop with that in mind, too. |
| C．You don’t have to choose shining paper to decorate a present. |
| D．In fact, many types of wrapping paper cannot due to their materials. |
| E．When wrapping paper is extremely thin, it has few good quality fibers for recycling. |
| F．Wrapping paper can be used many times if care is taken to unwrap it without tearing. |
| G．Having a mix of recyclable and non-recyclable papers is a real problem for companies. |

9 . It is a well-known fact that plastic bottles, which take hundreds of years to rot, are harmful to our environment. However, efforts by environmentalists to encourage consumers to switch to alternatives, like water fountains or reusable bottles, have not been very effective. The U.S. alone uses over 50 million plastic bottles annually, 80% of which end up in landfills.
To try to stop that, Rodrigo García González, Pierre Paslier and Guillaume Couche from the Imperial College London have been working on a revolutionary solution — water wrapped inside an eatable container made mostly from seaweed. All the customer has to do to relieve his/her thirst is pop the entire drop into the mouth.
The inventors, who have been working on the Ooho bubble since 2014, use a simple two-step cooking process called spherification (球化) to create the delicate container. They begin by dipping a frozen ball of water or juice into a chemical solution (溶液). This helps form a layer around the liquid. The ball is then absorbed in a solution made from seaweed extract. This creates a second layer, helping strengthen the structure so that the water or juice does not leak. In addition to saving our environment, the biodegradable (可降解的) packaging costs just two cents each, making it cheaper to produce than plastic.
After three years of perfecting the design, the inventors, who recently raised over 1 million USD from a financial activity, are ready to bring the Ooho bubble to local market. However, there are a few challenges that still need to be overcome before the product’s launch. In addition to getting accustomed to the taste of the covering, each eatable container contains just a mouthful of water, requiring consumers to drink multiple bubbles to relieve their thirst. There is also the issue of finding an eco-friendly packaging to transport the bubbles so that they remain clean and do not burst. Hopefully, the inventors will find ways to handle the issues so that we can reduce, or perhaps even remove, plastic bottles.

10 . Coral reefs in Florida have lost an estimated 90% of their corals in the last 40 years. This summer, a marine heat wave hit Florida’s coral reefs. The record high temperatures created an extremely stressful environment for the coral reefs, which are currently also experiencing intense coral bleaching (白化).
A coral is an animal, which has a symbiotic relationship with a microscopic algae (藻类). The algae gets energy from the sun and shares it with the coral internally. The coral builds a rock-like structure, which makes up most of the reef, providing homes and food for many organisms that live there. Coral bleaching is when the symbiotic relationship breaks down. Without the algae, the corals appear white because the rock skeleton becomes visible. If the bleaching continues for an extended period, the corals can starve to death without the energy.
Florida is on the front lines of climate change. It is also on the cutting edge of restoration science. Many labs, institutions and other organizations are working nonstop to protect and maintain the coral reefs. This includes efforts to understand what is troubling the reef, from disease outbreaks to coastal development impacts. It also includes harvesting coral spawn (卵), or growing and planting coral parts. Scientists moved many coral nurseries into deeper water and shore-based facilities during this marine heat wave. They are digging into the DNA of the coral to discover which species will survive best in future.
There are some bright spots in the story, however. Some corals have recovered from the bleaching, and many did not bleach at all. In addition, researchers recorded coral spawning. Although it’s not clear yet whether the larvae (幼虫) will be successful in the wild, it’s a sign of recovery potential. If the baby corals survive, they will be able to regrow the reef. They just have to avoid one big boss: human-induced climate change.
