1 . A powerful earthquake hit Morocco, killing thousands of people and causing huge damage over a large area.
The earthquake struck around 11 pm on Friday night. It was not only one of the most powerful earthquakes ever recorded in Morocco, but also the country’s deadliest earthquake in over 60 years. So far, the earthquake is reported to have killed over 2,900 people. The earthquake was especially precarious as it happened at night, when most people were asleep at home.
The center of the earthquake was in the Atlas Mountains, about 72 kilometers southwest of Marrakesh, a large city popular with tourists in the center of Morocco. Fortunately, many of its modern buildings survived the earthquake. However, the old part of the city, called the Medina, whose buildings are over 1,000 years old, was hit hard, leaving many of those buildings in ruins.
Outside of Marrakesh, the earthquake caused even more damage. In the Atlas Mountains, the earthquake’s center, there were many small villages. Many people in the area lived in simple houses made of mud, a traditional way of building in Morocco. But they’ re not strong enough to survive earthquakes and many of these houses simply fell apart, turning into sand. The Moroccan government has laws requiring buildings to be built more safely, yet these rules were often overlooked.
In larger cities, rescue efforts seemed to be going well. But it took a lot longer for help to reach remote (偏远的) areas in the mountains. That meant the local people in those areas had to deal with the situation on their own. They had to dig through the ruins with their hands, searching for survivors who were trapped. Moreover, many people were sleeping outside, unsure if their houses were safe enough.
More help was on the way. Many outside countries offered teams of experts and emergency supplies. But the government said too many different rescue teams could make the situation more confusing.

2 . As newer, more advanced technologies come out, huge amounts of electronics (电子产品) are thrown away, instead of being reused. These goods often end up in landfills, where the chemicals inside them may be a danger to the environment. Electronics can contain harmful materials. If these materials get into the ground or water, the pollution can cause serious problems. Most electronics require metals. These metals must be mined from the Earth. Often the mining process creates serious pollution.
A group known as Waste Electrical and Electronic Equipment (WEEE) Forum is trying to make people more aware of the problems of e-waste. Recently, the WEEE Forum asked researchers from the United Nations (UN) to study a kind of e-waste that’s often not noticed because people don’t consider the goods to be electronics. The WEEE Forum calls this kind “unable-to-be-seen” e-waste.
The UN study shows that about 1/6 of all e-waste is “unable-to-be-seen”. Though it’s “unable-to-be-seen”, it’s certainly not a small amount. The “unable-to-be-seen” e-waste weighs about 9 billion kilograms. The WEEE Forum says that if this e-waste were put into 40-ton trucks and the trucks were then lined up, the line of trucks would be about 5,630 kilometers long.
The surprising kind leading the “unable-to-be-seen” e-waste group was toys. Worldwide, roughly 7.3 billion electronic toys are thrown away each year. These include goods like car racing sets, electric trains, and musical toys. They also include toys with electronic parts, like dolls that speak or games with electronic timers. In all, toys make up about 35% of “unable-to-be-seen” e-waste. But the problem is far larger than just toys. The report also shows that other everyday goods like home alarms, smoke alarms, power tools, and computer cables (电缆) are also big sources of “unable-to-be-seen” e-waste.
The WEEE Forum is hoping that as more people and governments become aware of e-waste, they will make a much greater effort to make sure electronics get reused.

4 . Five years ago, we cut nearly every single tree across 19 acres here, piled and burned the branches and left the trunks where they lay. The goal was to restore one of the Ozarks’ rarest ecosystems, a type of dry and rocky grassland.
Logging down trees to bring back grass may seem puzzling in a time of climate change, as forest conservation and tree planting have become popular ways to keep carbon out of the atmosphere. But it is exactly what we should do in some parts of the Southeast. The climate and biodiversity crises are problems to be solved together. We can’t afford to rob biodiversity to pay for the climate. And grasslands are surprisingly good at pulling carbon out of the atmosphere. A single sunflower might not be the carbon grab that an oak tree is, but grass’s deep root systems store the element deep underground, where it can take hundreds or thousands of years to return to the atmosphere.
For the past century, the commonly held belief was that forests once covered most of the region from the Atlantic Ocean to the Mississippi River. But we now know that’s not true. Much of the Southeast was a string of large and small grassland ecosystems with enormous biodiversity. All of these unique grasslands are under threat, but not all by tree invasion. The few remaining grasslands in Arkansas are being converted to grow rice, Virginia grasslands are being flattened by housing developers, and low-lying coastal grassy plain is facing sea-level rise. Because grasslands are so easily navigated (导航) and settled, they may be the most threatened ecosystems in the world.
And it’s obvious that everywhere, grasslands remain undervalued. Many conservation organizations working in the Southeast are still focused on tree planting and preserving existing forests. The Nature Conservancy’s Cumberland Forest Project covers 253, 000 acres of land in Kentucky, Tennessee and Virginia, part of an effort to store carbon and create continuous habitats for species migration during climate change. In fact, recent laws are beginning to lead us in the right direction.

6 . According to a new study, human noise is a “major global pollutant” that harms a wider range of animal life than we tend to think. Published in the journal Biology Letters, the study suggests noise pollution not only harms lots of animals, but also threatens the survival of more than 100 different species.
Lots of species rely on sound for communication, for example, including many amphibians, birds, insects and mammals which use sound for vital business like finding mates or warning about predators (捕猎者). If noise pollution drowns out enough of these messages. it can threaten survival and the stability of their populations.
On the other hand, noise pollution can make it harder for some predators to find food Bats and owls rely on sound to hunt, for instance, which may not work if noise pollution drowns out the sounds of their prey like insects and mice. Even if noise pollution is mild, it might still force them to spend more time and energy searching for food, which could be enough to cause a decline.
Noise pollution is a well-known risk for whales and dolphins, but it threatens other sea animals, too. The researchers cite fish larvae, which are easily drawn to the sounds of coral reefs (珊瑚礁). This is how they find suitable habitats, but if their journey features too much noise from ships and other human sources, more fish larvae may get lost or move into wrong reefs, potentially reducing their lifespan.
Similarly, noise pollution influences the way animals migrate (迁徙), which in turn can have chain effects for ecosystems along migration routes. Some migrating birds avoid areas with noise pollution, the researchers note, which may change not only where they travel, but also where they establish long-term homes and raise their young. Many ecosystems and non-migrating species have come to depend on the arrival of migrating birds, and many others may be unprepared for their sudden absence, so this could cause a series of ecological changes.
“Noise must be considered as a global pollutant and we need to develop strategies to protect animals from noise for their livelihoods,” says Kunc, the lead author of the study.

8 . Solar stills (蒸馏器) provide a clever and simple means of purifying dirty or salty water, but they work at a rather slow rate. A new material has been shown to boost their performance, and it’s made from fruit waste which would otherwise be thrown away.
In its most basic form, a conventional solar still consists of a basin of undrinkable water that is set beneath a cover. The water evaporates (蒸发) as it’s heated by the sun, condensing (凝结) on the inside surface of the cover. That condensation—which is pure, clean water-drops down the cover and is collected in a separate container for drinking. In order to warm the dirty/salty water at a faster rate, scientists have developed materials that float on its surface, transforming sunlight into heat. They commonly use carbon obtained from coal.
To seek a less costly and more environmentally-friendly alternative, Prof. Edison and colleagues at Singapore’s Nanyang Technological University looked to something that is free for the taking—fruit waste. More specifically, the scientists tried out coconut peels, orange peels and banana peels.
In a simple carbonization process, the fruit waste was heated at 850℃for a few hours, and mixed with a kind of chemical substance. Doing so transformed the fruit waste into a new material which has a very highlight-to-heat transforming efficiency.
When tested in a small solar still, this new material proved to be very effective at transforming sunlight into heat, causing the dirty/salty water to evaporate much more rapidly. And because the material is full of holes, the waters team is able to rise right through it, subsequently condensing on the inside of the still’s cover.
Prof. Edison and his team found material obtained from the coconut peels worked best, as it transformed sunlight to heat with an efficiency rate of 94%. They are now developing the technology further, and are seeking industry partners to help with its commercialization.

9 . The popular documentary series Aerial China (航拍中国) recently returned to the small screen. The latest and fourth season of it gives a perspective that is both excellent and informative. As the final of the series, the new season was shot across 11 provincial-level regions and started in the spring of 2020.
“The experience from the previous three seasons makes us more capable to follow wild animals while avoiding disturbing them,” says Yu, chief director of the series. China has made great efforts to protect endangered wildlife species and their habitats in recent years, and it has become much easier to spot rare species in the wild. Taking Tibetan antelopes as an example, the plateau-based creatures were difficult to encounter in the past, but the expansion of their population and enhanced research on their living patterns have allowed the camera crew to tailor plans to follow the animals.
Most close-ups for the season were shot by photographers from helicopters or cameras installed on drones (无人机). The vital moment for a successful shot depends on the mood of the animals or how good the weather is,” Yu says. In an attempt to fully show China’s huge changes over the past decade, the documentary series consulted experts from different fields to help select the most attractive shooting sites. In the final season, Aerial China has used 73 helicopters and 320 drones to shoot footage over an area of 900,000 kilometers, and selected around 1,000 staffers. More than 30 teams were assigned to shoot in different cities for the fourth season.
The previous three seasons have been watched by 850 million TV viewers and seen online over140 million times. For fans of the series, the director says he hopes that the new season will draw a bigger audience with its unusual perspective to show them China like never seen before.
