The day starts early for Shi Xiaogang, a wildlife ranger (护林员) at the Wolong National Nature Reserve in Southwest China’s Sichuan province. He monitors the population of giant pandas and conducts long-range patrols (巡逻) in some of the most extreme environments,     1     is a challenging and, often, dangerous job.

    2     (cover) about 200,000 hectares, Wolong National Nature Reserve is home to one of the largest remaining giant panda populations in China. Thanks to the rangers’ like Shi’s efforts,     3     number of wild giant pandas in the reserve has increased from 104, in 2015, to 149 today. In 2016, the International Union for Conservation of Nature     4     (announce) that the giant panda’s status had been changed from “endangered” to “vulnerable” on its Red List of Threatened Species.

As well as “the home of giant pandas”, the reserve is     5     (wide) known as a “bio-gene bank”. It features a great number of threatened species of plants and animals, including other famous     6     (creature), such as the red panda, snow leopard and clouded leopard among the 121 species of mammals (哺乳动物)     7     (record). There are also 392 bird species.

To mark the rangers’ hard work and contribution to wildlife     8     (protect) in the reserve, last year, 20 rangers     9     (recognize) with special commendations (表扬) at an online award ceremony for the IUCN World Commission on Protected Areas’ International Ranger Awards.

The commission speaks highly of their work, saying that they help stop biodiversity loss and protect the important ecosystems that serve     10     natural solutions to climate change and other global challenges.

3 . The Atlantic salmon (鲑鱼) of Scotland are hardy and determined animals. Each spring and summer, they return from the North Atlantic Ocean to lay eggs in Scotland’s shallow rivers,leaping up waterfalls and over barriers, pushing themselves upstream in enormous efforts. Some fail, and others succeed, but today they face yet another challenge.

During the mid-1980s, there were between eight and ten million salmon swimming around Scotland’s Atlantic coast; that number has now dropped sharply. There’s evidence of reducing the availability of the salmon’s prey (猎物) as climate change warms and acidifies oceans. New research suggests climate change is also bearing down on rivers, which is bad news for salmon.Adapted to life in cold water, salmon experience slow growth and population changes at high temperatures. Heat influences their health and reduces their resistance to disease.

“Now salmon are struggling to deal with the rising temperatures. There are recent records of 27°C in the upper reaches of the Dee catchment,” says Peter Cairns, director of an environmental charity. In 2018, Scotland recorded the lowest pole catch for salmon since records began. Evidence suggests that the degraded quality of river worsens the impact of our changing climate. “Atlantic salmon evolved using river systems in Scotland that were once way more forested and therefore shaded.” Yet Scotland is today one of the least wooded countries in Europe, with just 3 percent of its native woodland undamaged. Scientists have found that just 35percent of rivers in Scotland have enough tree cover for salmon survival.

A movement to get trees back on riverbanks is gathering pace. “Broad-leaf trees close tothe bank can reduce the light that enters the water,” explains fisheries scientist Anthony Hawkins. A new initiative called Riverwoods — led by the Scottish Wildlife Trust and supported by Scottish Water and several other government and regulatory bodies — aims to create a network of woodlands along Scotland’s riverbanks, and has already received a number of large funds.“Money is not the pressing business. River health is complex, but tree planting is one of the most basic things we can get started with right away,”says Cairns.

7 . 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.

9 . 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.

10 . 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.”
