4 . For the past 13 years, Martin Burrows has been working as a long-distance truck driver. Spending up to five nights a week on the road can be a lonely business, leaving him with plenty of time to notice his surroundings. “I kept seeing more rubbish everywhere and it was getting on my nerves. I decided I had to do something about it,” he says. One day, he stopped his vehicle, took out a trash bag and started picking up the garbage. The satisfaction after clearing a small area was remarkable.

Before his time on the road, Burrows spent over two decades in the military as a vehicle driver. His service saw him stationed throughout Europe and also on tours in Afghanistan. After returning to civilian life, he was diagnosed with PTSD (创伤后应激障碍) and had a mental health crisis in 2017. His involvement in fundraising for Help for Heroes led him to meet a man who used model-building as a distraction from PTSD. Burrows realized that his act of roadside cleanup had a similar calming effect on his mental well-being.

By 2019, Burrows had begun using his free time on the road to regularly clean up garbage. A passerby encouraged him to set up a Facebook group, which he called Truckers Cleaning Up Britain. “I was worried I’d be the laughing stock of my town for putting videos and photos up of me cleaning but people started to join,” he says. “I was amazed. The local council stepped in and gave me litter-picking supplies and we’re up to almost 3,000 members now.”

Since truckers are so often on the move, the Facebook page acts as a means of raising awareness rather than a platform for organizing cleanups. Burrows expressed his intention to continue the cleanup efforts as long as his physical condition allowed, as he still found joy in the process.

5 . Damon Carson calls himself a matchmaker (媒人) of the never-ending waste of American society, trying not to pair people with people, but things with people.

In the late 1990s, Carson was on break from business school in Vail, Colorado, when he discovered the vast world of waste. He began thinking about creating a secondhand store that would sell old materials and keep them out of being wasted. As a result, in 2010, his company, Repurposed Materials appeared.

For nearly ten years, his company, Repurposed Materials, has not been looking to recycle the waste he gets — breaking it down to make something new — but rather finding new homes for thrown-away goods in their original forms.

Carson, a husband and father of three adult children, is far from wasteful. Frugal is how he describes himself. The clothes he’s wearing all came from a charity shop; his truck was bought with 290, 000 kilometers driven.

“Why break something down, why melt something down, if it still has value?” he asks. An old oil-field pipe might be melted down and turned into a car bumper, but it still takes an amount of power to finish the complete change. Why not leave it as a steel pipe? Why not turn it into a fence post on a farm? The only cost is transport.

American industrial facilities create and throw about 7.6 billion tons of unwanted industrial materials every year. For the moment, Carson’s unique business finds new lives for millions of kilograms of industrial waste every year.

6 . For years, twice a day Aadya Joshi walked past a dump filled with smelly rubbish in her neighbourhood of south Mumbai on her way to and from school. Originally it was meant to be the garden of the local police station. When she was 15, during her summer holidays, Joshi decided to do something about it. “I walked into the police station and was like, ‘Can I please clean your garden?’” recalls Joshi. “It took three or four weeks to eventually convince them that I was not going to give up halfway and leave them with more work.”

The plot of land covers an area of 60 square meters, about a quarter of a tennis court. But, over the course of four Sundays in the summer, with help of local residents, Joshi did more than clear it. She replanted it with native Indian plants and trees. Joshi said, “The first day that we cleaned up I made the mistake of not wearing gloves and I was sick for two weeks.”

The idea for native planting came from Joshi’s reading on the Miyawaki method of afforestation (植树造林) and the work of University of Delaware ecologist Douglas Tallamy. These both argue that planting the right trees can have a significant impact on restoring insect and animal biodiversity. The results in Mumbai were instantaneous: monkeys now hang out at the police station, and butterflies and birds have made the garden their home.

After creating the garden, Joshi developed a database of 2,000 plants unique to the Indian subcontinent and last year was awarded the annual Children’s Climate prize, founded by Swedish energy company Telge Energi. Her advice for others looking to follow in her footsteps: “If you bite off more than you can chew in the beginning, you will be stuck and lose motivation,” she says. “But something small, like your neighbourhood police station, it’s very manageable.”

7 . Coral reefs are the rainforests of the ocean. They exist on vast scales and are equally important havens of biodiversity. Reefs occupy 0.1% of the oceans.     1    

Corals are useful to people. Without the protection which reefs afford from crashing waves, low-lying islands such as the Maldives would have flooded long ago, and a billion people would lose food or income. However, reefs are under threat from rising sea temperatures. Heat causes the algae (海藻) with which corals are living together to generate toxins (毒素) that force those coral to leave.     2    

Research groups around the world are coming up with plans of action to see if that will help, such as identifying naturally heat-resistant corals and cross-breeding such corals to create a new type.     3     Without carbon reduction and decline in local, coral-killing pollution, even resistant corals will not survive the century.

Doubters doubt humanity will get its act together in time to make much difference.

    4     Carbon targets are being set and ocean pollution is being dealt with. Countries that share responsibilities for reefs are starting to act together. Scientific workarounds can also be found. Natural currents can be applied to facilitate mass breeding. Sites of the greatest ecological and economical importance can be identified to maximize bang for buck.

    5     It could serve as a blueprint for other ecosystems. Hard-core greens — those who think that all habitats should be kept unspoiled — may not approve. But when entire ecosystems are facing destruction, the cost of doing nothing is too great to bear.

About 385, 000 people from 192 countries take part in the yearly project to count birds. The event    1    (launch)for the first time 25 years ago.

Steve and Janet Kistler from the American state of Kentucky are among those     2    (involve) themselves in it. They’ve done so every year    3    the now-international tradition started in 1998. For Moira Dalibor,     4     schoolteacher from nearby Lexington, this is her first event. She’s leading a group of students and parents to a garden     5    (collect) data.

Becca Rodomsky-Bish,    6    works at the Cornell Lab of Ornithology in New York, is the project’s leader. The Lab organizes the Great Backyard Bird Count (GBBC) along with the National Audubon Society and Birds Canada. “Every year we see increased participation, and 2022 was a big jump,” Becca said. In India, which had the     7    (high) participation outside the US last year, tens of thousands of people submitted bird checklists.

The worldwide data goes into the eBird database used by scientists for research on different bird     8    (population). The GBBC is part of a rise in “citizen science" projects in which volunteers collect data about the    9    (nature) world for use by researchers. The information helps researchers track the numbers of different kinds of birds, which then helps with their     10    (protect).
