1 . Sri Nihal Tammana, age 13, of Edison, New Jersey, was named a winner of the 2022 Gloria Barron Prize for Young Heroes. The Barron Prize annually honors 25 outstanding young leaders who have made a significant positive impact on people, their communities, and the environment.
Nihal founded Recycle My Battery to promote and facilitate the recycling of used batteries. His nonprofit places free battery recycling bins(箱子)and educates young people and adults about battery recycling. In just three years he has built a team of more than 250 student volunteers across the globe who have recycled nearly 200,000 batteries and educated millions of people. Nihal learned at age 10 that 15 billion batteries are thrown away each year and that most end up in landfills(垃圾填埋地)where they pollute groundwater, harm the ecosystem, and can cause catastrophic fires. Inspired to tackle the problem, he began collecting used batteries from his community. He put them in free recycling bins at stores like Staples until he was told he was bringing too many and had to stop.
Undeterred, he reached out for help from Call2Recycle, the largest battery recycling nonprofit in North America. Call2Recycle agreed to assist and provided recycling bins for free, which were placed in schools, libraries, and other public places. Nihal’s organization now operates across the U.S. and is expanding to other countries including Canada, Switzerland, and India. “Earth gives us so much — oxygen, food, water — everything! So it’s important that we give something back when we can,” says Nihal.
The Barron Prize was founded in 2001 by author T. A. Barron. “Nothing is more inspiring than stories about heroic people who have truly made a difference to the world,” says T. A. Barron. “And we need our heroes today more than ever. Not celebrities, but heroes — people whose character can inspire us all. That is the purpose of the Barron Prize: to shine the spotlight on these amazing young people so that their stories will inspire others.”

3 . It is late autumn—millions of gardeners across the northern hemisphere, pulled on their thickest sweaters, spent hours clearing large piles of leaves and packed them into plastic bags at the end of driveways.
In the US alone, nearly 10 million tonnes of garden waste go to landfill every year. That is a large amount of effort, not just from an environmental viewpoint but from that of our aching backs, too. So where does this advice come from? Well, it largely comes from the belief that thick fallen leaves can make plants under them unable to breathe, especially shorter grass. They shut down important photosynthesis (光合作用) and get in the way of the growth of the shorter grass. However, this received wisdom has recently been questioned by researchers at Wisconsin University.
The key finding of their new research was that although clearing fallen leaves is one of the most common gardening practices, it makes very little sense. In natural ecosystems, fallen leaves help return nutrients necessary for healthy plant growth to the soil, which greatly improves soil condition. Removing leaves year after year breaks this ecological (生态的) balance. Letting some leaves stick around to cover your garden is a great way to help your grass and the local ecosystem.
They further explained that if up to 50percent of your grass lawn (草坪) is covered by fallen leaves, you might as well go back indoors and put your feet up. The advantages of this light leaf coverage far outweigh the disadvantages—the leaves will quickly break down and help next year’s lawn grow far better than if you had cleared them. Only at over 50 percent coverage do the Wisconsin researchers recommend clearing.
So why not consider leaving the leaves? Save time, carbon and effort, and in exchange get a healthier lawn from this garden waste—that seems like a pretty good deal. And how many plastic bags could be saved by simply not binning fallen leaves every year? In the US alone, about 700 million.

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. |
8 . From Dec 7 to 19, delegates from around the world met at the 15th meeting of the Conference of the Parties to the United Nations Convention on Biological Diversity (also known as COP15), in Montreal, Canada. After two weeks of intense debate at COP15, delegates agreed on Dec 19 to adopt a landmark plan to halt and reverse biodiversity loss by 2030. “Finally, we reached our destiny. We adopted the Kunming-Montreal Global Biodiversity Framework,” Huang Runqiu, COP15 president and China’s minister of ecology and environment, announced on Dec 19.
The new framework is a commitment by 196 parties to the Convention on Biological Diversity to conserve at least 30 percent of the Earth’s land and ocean area by the next decade. It also will increase the expected annual financial assistance from developed countries through 2030 to help developing nations with biodiversity protection.
The aim of COP15 is to ensure biodiversity loss is changed by 2030, and that humans are able to live in harmony with nature by 2050.To realize these objectives can be very challenging. At COP10 in Nagoya, Japan in 2010, the parties agreed on the 20 Aichi Biodiversity Targets (爱知生物多样性目标). But, as of now, none of the 20 objectives has been fully realized.
It is important to turn consensus into effective actions. Yet, as recent talks have shown, an aspect of effective international action on stopping climate change is the cooperation of developed countries. Developed countries, however, have fallen short of their responsibility as they have failed to fulfill the obligations according to the COP convention to provide funding and technology to poorer nations who lack the means to combat climate change.
To solve this problem, the framework creates a new biodiversity fund within the UN’s existing Global Environment Facility. This came about as a compromise between developing nations, which wanted a new fund, and developed countries, which did not. In addition, a global youth initiative (倡议) was also released, hoping young people to be leaders and advocates for biodiversity conservation.
1. What is the aim of COP15?| A．To save at least 30 percent of the Earth’s land and ocean area by next decade. |

9 . Roads and railways have made it easy for people to travel around the UK, but have had the precisely opposite effect for insects. Alongside housing developments, transport infrastructure (基础设施) has separated insect habitats, leaving many pollinators (传粉昆虫) stuck on decreasing islands of biodiversity.
A new conservation project aims to address that by creating a network of wildflower superhighways across the UK. The B-Lines network aims to join the dots between meadow habitats, enabling pollinators and other wildlife to move freely between them. Ten years in the making, the B-Lines initiative was launched by the insect charity Buglife on Tuesday and has already generated interest from unexpected quarters. “After the launch, some house builders rang up asking how they could include the network into house building, so it could have a really positive effect,” said Buglife’s Paul Hetherington.
Buglife has spent the last decade mapping potential routes for the insect superhighway. Hetherington said the proposed highway could give the UK’s weak insects a boost and a route out of habitats that become too hot due to the climate crisis and it can make a huge difference in easing declines. “The things that have really hammered pollinators are habitat loss, loss of connectivity of habitat, climate change and pesticides—this deals with everything except pesticides,” said Hetherington.
The B-lines network is not just a concept. Pilot sections have already been completed, including the South Wales B-Lines near Cardiff. “Since that was done, there have been recordings of one of our rarest bees in Cardiff town centre, which shows this connectivity can work,” said Hetherington. And in Norwich, Buglife has been working with Network Rail to plant wildflowers along the track. Anyone living along the proposed route can get involved in the project. All they need to do is let their lawns grow, or even just create a small herb garden, which Hetherington likened to creating a “motorway service station for bees”.
