1 . Have you ever wondered what happens to your mobile phones and laptops after you throw them out to make way for a newer model? According to its latest Global E-Waste Monitor, India is the third top producer of e-waste in the world. E-waste in Indian landfill goes on to pollute soil and groundwater, affecting food supply systems and water sources.
Thankfully, the country has a new group of artists who are changing these thrown mechanical items-from mobile phones to old televisions- into large murals (壁画) and artworks to creatively show their concern for the waste problem.
Over the past quarter of a century, Mumbai’s Haribaabu Naatesan has transformed hundreds of tonnes of e-waste into art, integrating elements from nature and industry. “I get my waste material from friends, relatives and neighbours who know my interest in e-art and send me bags of thrown electronic appliances,” says Naatesan. Over his career, he has created huge murals for several companies. He has also showed his work at the India Art Fair, as well as several other national displays.
Another artist Vishwanath Davangere has also long worked with e-waste. He likes to take apart old laptops and reassemble (重新组装) them into birds, animals and plants. After retirement, he started pursuing this hobby more seriously and started selling his creations across the world. His most outstanding works include a robotic Egyptian statue with glowing red eyes and a Milky Way made from keyboard keys. He hopes to enable others to reconsider their own consumption habits and make more environmentally conscious choices.
“By giving e-waste a second chance, I aim to raise awareness about the environmental impact of electronic waste.” says Davangare, who today has a collection of more than 600 eco-art objects.

2 . A shocking 53.6 million metric tons of electronic waste was discarded last year, a new UN-backed report has revealed. The report shows that e-waste is up by 21% from five years ago. This isn’t surprising, considering how many more people are adopting new technology and updating devices regularly to have the latest versions, but the report also shows that national collection and recycling strategies are nowhere close to matching consumption rates.
E-waste contains materials including copper (铜), iron, gold and silver, which the report gives a conservative value of $ 57 billion. But most are thrown away or burned rather than being collected for recycling. Precious metals in waste are estimated to be worth $ 14 billion, but only $ 4 billion-worth is recovered at the moment.
While the number of countries with national e-waste policies has grown from 61 to 78 since 2014, there is little encouragement to obey and a mere 17% of collected items are recycled. If recycling does occur, it’s often under dangerous conditions, such as burning circuit boards to recover copper, which “releases highly poisonous metals” and harms the health of workers.
The report found that Asia has the highest amounts of waste overall, producing 24.9 million metric tons (MMT), followed by Europe at 12 MMT, Africa at 2.9 MMT, and Oceania at 0.7 MMT.
But whose responsibility is it? Are governments in charge of setting up collection and recycling points, or should companies be responsible for recycling the goods they produce? It goes both ways. Companies do need to be held accountable by government regulations and have incentives to design products that are easily repaired. At the same time, governments need to make it easy for citizens to access collection points and deal with their broken electronics in a convenient way. Otherwise, they may turn to the easiest option — the landfill.

4 . A man named Randy liked to look for big trees and old trees. He made maps to show where these trees were. He did not want to cut them down. He wanted people to take care of them.
Randy was told that there was a very tall tree on Vancouver Island. The tree was said to be 314 feet tall. That would make it the tallest tree in Canada. Randy started to find the tree.
But someone else found it first. It was found by a logger (伐木工). Loggers wanted to cut down Canada’s tallest tree and all the trees around it.
Randy made a path in the forest so people could see the tallest tree. The tree was so big and beautiful that it would bring them enjoyment. More and more people wanted to save that forest. Thanks to these people, that forest is now a park. Canada’s tallest tree is still there.

5 . The earth is struck daily by 60 tons of rocks from outer space. However, finding these ancient rocks is no easy task. Most meteorites (陨石) fall directly into water. And those that hit land can be difficult to spot among other rocks.
Fortunately for researchers there is one place on Earth where meteorites find it difficult to hide: Antarctica. “There are probably fewer meteorites falling per acre of land in Antarctica than in other parts of the world,” said Ralph Harvey, a professor at Case Western Reserve University. “But if you want to find things that fell from the sky, lay out a big white sheet. And Antarctica is a 5,000-kilometer-wide sheet.”
Finding meteorites in Antarctica is so relatively “easy” compared to the rest of the world that an estimated two-thirds (around 45,000) of those ever discovered have come from the icy continent. The challenge, however, comes not only from the terrible conditions, but also from knowing where to look to make any expedition worthwhile.
In an effort to greatly improve the collection rate of Antarctic meteorites, a Belgian—Dutch team of scientists has unveiled (展示) what they’re calling a “treasure map” for the region. “We expect the treasure map to be 80% accurate,” said Veronica Tollenaar, who led the study.
After landing in the snow in Antarctica, a meteorite will either be directed into the ocean or brought back to the surface of what’s known as a “blue ice” area. As meteorites come out in these special “blue ice” areas, their color contrasts (对比) against the deep blue ice, making them easy to spot. The treasure map marks more than 600 special “blue ice” areas. They estimate that these sites may contain anywhere from 340,000 to 900,000 surface meteorites.
The researchers add that these locations also likely contain rare meteorites, such as angrites, brachinites or even Martian meteorites.
“Collecting these ancient rocks will further improve the understanding of our Solar System,” they write.

8 . For Cruz, who grew up in Peru’s mountainous region of Cuzco, fog represents a massive opportunity. As a boy, he had to hike for more than an hour every day across hills to collect water from the nearest source. But over time, he realized that during the rainy season, droplets of water would gather in the large leaves of banana trees. So one day he and his father tried to build a canal system with the leaves to collect water and it turned out a success. But afterwards, he moved to Lima at the age of 25.
There, shocked by the water shortages and expensive water supply that some of the city’s poorest residents were faced with, Cruz set up El Movimiento Peruanos sin Agua in 2005. The idea was to deploy the method he learned in his hometown on a larger scale, which would provide free, independently sourced and easily accessible water to those who needed it most. He began installing (安装) a traditional fog catcher model developed in the 1980s.
At the highest point of Los Tres Miradores, there is a curious set of large structures that resemble a fleet of ships in the sky. They are so-called “fog catchers”. Netted devices, made of high density Raschel polyethylene and spanning several meters wide, are lined up at the top of a misty mound and linked by a network of tubes that lead to storage containers. The 40 fog catchers there provide enough water for 180 families, whether to bathe, clean, drink or to irrigate crops on small garden patches.
Supporters believe that fog catchers have the potential to improve water supply for communities around the world among the ever-challenging circumstances. German researcher Lummerich says, “They are cheap, easy to construct.” In a world searching for water supply systems, it is one important puzzle piece that can make an essential difference locally.
However, there are some issues. For one, fog catchers require space, which is not always easy to come by in cities, let alone urban slums. At the same time, fog catchers must be properly cleaned and maintained to stay effective. Most crucially, appropriate climate conditions are required. Fog isn’t everywhere.

9 . It has been more than 40 years since anyone spotted a Japanese river otter (水獭). And the once common Tangtze River dolphins have either disappeared or are very rarely seen.
A huge challenge scientists and conservationists encounter is tracking species facing extinction in order to help them.
In Brazil, AI quickly analyzed over 150, 000 satellite images, revealing that the world’s largest tropical wetlands lost 74 percent of its surface water.
The use of AI has helped to accelerate action and increase conservationists’ ability to protect the natural world for generations to come.

| D．Saving them was challenging because their whereabouts (行踪) were relatively unknown |
| E．These are just a few of the species that have been listed as extinct or locally extinct in recent years |
| F．However, because of weather conditions, researchers knew next to nothing about their winter behavior |
| G．This is where AI has brought about a revolution in the way data on these species is collected and analyzed |
10 . Lying in the Mexican state of Oaxaca, the fishing village Huatulco is home to nine bays, 36 beaches and thousands of baby turtles that apparently needed me. I had three open days on my calendar, and a desire to save some turtles. And so, away I went to Huatulco with Wildcoast, a group of champions-for-change who were protecting coastal and marine ecosystem in the U. S. and Mexico.
I was taken to La Escobilla to experience Wildcoast in action. Just one hour north of Huatulco, this protected beach is where mass turtle nesting happens. This natural phenomenon lasts just four days during rainy season, hundreds of thousands of female sea turtles swinging their way ashore to lay their eggs.
Between threats of dogs, crabs, development and oil spills, the little creatures have the whole world against them. As recently as 2002, turtles hunting was not only a common practice, but an important part of the culture and diet in the Oaxaca communities. Luckily, Wildcoast rescues turtle eggs and recreates habitats by monitoring temperatures and humidity. Thanks to their efforts, the sea turtles have made a major comeback, with now over 72 million turtles being born on the beaches that Wildcoast protects.
I got to hold 50 of the tiny creatures in a bowl. Despite an average laying of 100 eggs, just one in 1, 000 baby turtles will make it to adulthood. Gazing into the bowl, I so badly wanted them to taste the sea and find shelter somewhere deep in the ocean. Finally, it was time to liberate those little creatures. Out spilled the creatures, some moving full steam ahead while others barely paddled in place. Literally, hundreds of them began to spread out across the beach.
With each set of waves, we witnessed the survival of the fittest, some pushing past the whitewash while others crashed back to shore. Their fight for life made my eyes wet. A flock of birds were ready to dive into the sea for their moving targets. “One in 1, 000.” Nature was cruel and compassionate at the same time. After 30 long minutes, the last creature made his way to the sea.
