King Canute couldn’t stop the ocean’s tide from rolling in — can Africa hold back the desert?That’s certainly what the continent is tying to do with its proposed “Great Green Wall”, 800km (almost 500 miles) worth of trees that officials hope will stop the advancement of the Sahara Desert, which has been rapidly expanding southward.
The idea was introduced in the 1970s when the once-rich region turned barren (贫瘠的) due to climate change and intensive land use. But it’s not a new idea; China has its own desert vegetation project to hold back the Gobi Desert! Thanks to the Chinese plan, the African project aims to plant 100 million hectares of trees by 2030 across the entire Africa. The initiative is a decade in, and around 15% completed, and there have already been benefits for many communities and wildlife. It’s bringing life back to the continent’s degraded landscapes at an unprecedented scale, providing not only food security and jobs but a reason to stay for the millions who live along its path.
The creators of the wall hope it will bring an urgently needed solution to the threats facing the African continent, creating 10 million jobs in rural areas, as well as preventing 250 million tons of carbon. The initiative is Africa-driven, which for those on the continent, is vital, and may hold the key to success. “The Great Green Wall…is about ownership, and that has been the failure of development aid because people were never identified with it,” said Elvis Paul Tangam, African Union Commissioner for the Sahara and Sahel Great Green Wall Initiative.“But this time they identify. This is the very thing of us!”
The wall may seem like a moonshot, but all the best ideas usually are. As Thomas Sankara, former president of Burkina Faso said in 1985, “You can not carry out fundamental change without a certain degree of madness. The courage to turn your back on the old formulas, the courage to invent the future.”

【推荐2】By the twentieth century, New York City had long since reached its destiny of becoming the most powerful city in America. In less than 300 years it had grown from a tiny Dutch outpost in the wilderness to the business capital of the world. It was a city built on dreams,
But it was made out of bricks and cement that had come from the banks of the Hudson. The river which had fed all those dreams was now fading into the background. New York didn’t seem to need the river anymore, except as a sewer. And that’s what it became.
Industry on the river had made some New Yorkers filthy rich. But it had just made the river filthy. Garbage, factory waste, plant chemicals and the raw sewage of the cities and towns along its banks were dumped directly into the river. The water turned greenish brown, except by the GM plant, where it turned red or yellow or whatever color they were painting the cars that day.
The fishing industry collapsed. The few fish that survived were too poisonous to eat. Smog from the factory smoke and dust from the cement plants blanketed the valley. And it was all legal.
Most people don’t start out which dreams of polluting a river. But it was often the result of people chasing their dreams of wealth with little care of how they reached it. The Hudson Valley had always drawn them.
But now there were other dreamers in the valley, with their own dreams of wealth. They dreamed of the wealth of wildlife in a healthy forest, the abundance of fish in oxygen—rich water, and the great fortune of living in a beautiful river valley.
So perhaps it was a matter of time before the two types of dreamers would meet each other—in court. In 1963, Con Edison, New York City’s power company, proposed a plan for constructing the largest hydroelectric pumping station ever built. The plan called for carving out a gigantic hole in the side of majestic Storm King Mountain on the Hudson River.
But then they met Franny Reese, a longtime valley resident with a simple point to make: the mountain could not speak for itself. If she didn’t speak for it, who would?
Franny and a group of like—minded people founded Scenic Hudson and took on the power company in a landmark court case. Con Ed challenged the right of private citizens to participate, but the court sided with the citizens, in the ruling now known as the Scenic Hudson Decision.
After dragging out the case for seven years, Con Ed finally gave up and Storm King survived unblemished. It was the beginning of the environmental movement in this country, and and again, the Hudson Valley was the birthplace.

【推荐3】A librarian in Indonesia's Java island is lending books to children in exchange for trash to clean up the environment and get the kids to read more.

She told Reuters the is helping promote reading in the kids as well make them aware of the environment. As soon as she shows up, little children, many accompanied by their mothers, surround her “Trash Library” and shout for the books. They are all carrying trash bags and Raden's three-wheeler quickly fills up with them as the books fly out. She's happy the kids are going to spend less time on online games as a result.
“Let us build a culture of literacy from young age to lessen the harm of the online world,” Raden said. “We should also take care of our waste in order to fight climate change and to save the earth from trash,” Raden said. She collects about 100 kg of waste each week, which is then sorted out by her colleagues and sent for recycling or sold.

Kevin Alamsyah, an 11-year-old book lover, search for waste lying in the village. “When there is too much trash, our environment will become dirty and it's not healthy. That's why I look for trash to borrow a book,” he says.
Jiah Palupi, the head of the main public library in the area, said Raden's work strengthened their efforts in a novel way to battle online gaming addiction among the youth and promote reading.
The literacy rate for above-15-year-olds in Indonesia is around 96 percent, but a September report by the World Bank warned that the pandemic will leave more than 80% of 15-year-olds below the minimum reading proficiency (阅读水平) level identified by the Organization for Economic Cooperation and Development.

【推荐1】Now several cities and states are considering passing laws when it comes to people who walk while texting (发短信). A law passed in Honolulu allows police officers to fine pedestrians(行人) between $15 and $99 for staring at their phones while crossing the street.
“Unluckily, we’re a major city with more pedestrians on the crosswalks, particularly our old people, than almost any other city in the country,” said Honolulu mayor Kirk Caldwell at a meeting. “So, passing a law is necessary and timely.”
The town of Montclair, California, took it one step further and passed a law making it illegal to talk, text or use earbuds (耳塞) on the phone when crossing the street. For the first time, people will be given a warning, and after that, the fine is $ 100. What’s more, farther north in Ontario, under the “Phones Down, Heads Up Act”, pedestrians can be fined if caught crossing the road while holding and using the phones. Fines start at $ 50.
This movement to pass such laws has a reason: Pedestrian deaths are on the rise. According to the National Safety Council, there were 5,987 pedestrian deaths—the highest number since 1990. This problem isn’t new, nor is it limited to deaths. There are a rising number of injuries from texting while crossing a street.
According to research, texing resulted in a higher rate of incidents than failure to look right or left when crossing. By comparison, talking on the phone led to only a slight increase of accidents and listening to music had no influence on safety. The results were published in the journal Injury Prevention.
So, in the opinion of David Canepa, a member of the Board of Supervisors in San Mateo Country, California, the government should tell people where to look when they’re walking down the street. He said, “At the end of the day, people will understand the value of public safety. Making the laws will save lives.”

【推荐2】A simple, yet powerful UK program has been fighting elderly loneliness by recruiting young adults as volunteers to read to seniors with vision problems and mental diseases.
Lily has benefited from the program having her vision “restored” by 15-year-old Amy, a school girl who was paired with Lily through the Reading Friends project. Lily was a librarian and enthusiastic reader who would read “two to three books every week”. After developing a terrible disease, however, Lily found herself unable to read or watch television for any length of time without her eyes hurting. Not only have Lily’s regular reading sessions with Amy helped to reconnect her with her passion for literature, they have also built a song inter-generational friendship between the two ladies. “I chose a book and she would come along and read it to me,” Lily said. “But we have only got through two books so far because we end up catting too much. We have read two historical novels and get on very well.” Research shows that reading together can help older people to build social networks and connect with others. Evidence also shows that reading has a positive impact on the elderly’s will-being and can reduce the risk of developing mental diseases.
Rose, a teacher, is responsible for connecting school children like Amy with the program—and she says that it has had an amazing impact on the youngsters. “We have wonderful young people at our school and we wanted to get then into the community,” Rose said. “It has been fantastic to see them blossom as well as improving their literacy and social skills. They are meeting community members like Lily that they are making friendships with and library staff can help them, not only with education but outside as well.”
