2 . A new study warns that more than a fifth of all reptile (爬行动物) species are threatened with extinction, which may have a bad impact on the planet.
The largest ever analysis of the state of the world’s reptiles, published in Nature, has showed that 21% of the reptile species are facing extinction. The study says from lizards to snakes, such a loss could have disastrous impacts on ecosystems around the world.
Although many reptiles live in dry environments such as deserts, most species occur in forests, where they suffer from threats such as logging of land for agriculture.30% of the forest-dwelling reptiles are at risk of extinction, compared with 14% in dry habitats. Hunting is also a major threat to reptiles, especially turtles and crocodiles, many of which are at risk of extinction. Another major contributing factor is the introduction of invasive species.
“If we removed reptiles, it could change ecosystems fundamentally, with unfortunate knock-on effects, such as increases in pest insects,” said Neil Cox, co-leader of the study. “Biodiversity, including reptiles, supports the ecosystem services that provide a healthy environment for people.”
Our hope is that this first-ever assessment of the world’s 10,000-plus reptiles helps put them in the spotlight and goes some way to highlighting this diversity, and just how much we have to lose. As well as controlling rats, mosquitoes and other pests, reptiles deliver many other benefits. “They help spread seeds, especially in island environments,” said researcher Hoffmann. “We’ve also achieved many medical advances from studies of reptiles.”
The results of the study are not all doom and gloom. Scientists have found, surprisingly, that if they set out to protect places where threatened birds, mammals and amphibians (两栖动物) live together, they’ll meanwhile protect many more threatened reptiles.

3 . Plastic is everywhere in our modern world. Its toughness makes it an extremely useful material from household items to vehicle parts, but that same toughness makes it hard to break down for recycling or disposal (处理). However, Japanese scientists at the University of Tokyo have developed a new plastic material that can be broken down more easily and can self-heal and remember past shapes.
Based on a kind of plastic called an epoxy resin vitrimer, which is brittle (脆性的), the new plastic boasts a huge range of advantages. Once scratched with a knife, it can completely patch itself up after being heated to 150 ℃ for just 60 seconds. When shaped into the shape of a crane, then flattened, it can fold itself back into the crane shape by being heated up. It does all of this much faster than others of its type.
The new plastic can also break down easier. Even if it’s discarded (丢弃) into the environment, it still poses less of a, problem than other kinds of plastic, which the team demonstrated by placing it in seawater for 30 days. It biodegraded by 25% and released molecules (分子) that are essential food for marine life.
The new plastic is more resistant to breaking. It can also repair itself, and can recover its original memorized shape. It even biodegrades safely in a marine environment, according to Shota Ando, a researcher of the study.
The material can be used in a variety of applications, “Infrastructure materials for roads and bridges are often composed of epoxy resins mixed with compounds such as concrete and carbon,” said Ando. “By using the new plastic, these would be easier to maintain as they would be stronger and healable using heat. Unlike conventional epoxy resins, this new material is hard but stretchable, so it could also be expected to strongly bond materials of different hardness and stretch.”

4 . Landscape architect Kotchakorn Voraakhom has designed a new green roof on the Rangsit Campus of Thammasat University, about 25 miles north of central Bangkok, Thailand. Her imaginative work challenges the common thinking that urbanization has a negative impact on the planet, whether flooding, excess (过度的) energy use, disrupted (扰乱) biodiversity or the heat island effect.
The 236, 806-square-foot structure, which opened in December 2019, includes a flood water management system and Asia’s largest rooftop organic farm. It combines modern landscape architecture with traditional agricultural knowledge, creating a green and friendly environment.
The green roof, containing an H-shaped landscape, looks like a futuristic hill with a brick building beneath it. The hill features a complex pattern of zigzagging terraces (之字形梯田) of planted beds, leading all the way down to the bottom. When rainwater hits the roof, it flows down the zigzags while being absorbed by the soil in the beds, The excess water is directed into four storage ponds — with a capacity of up to 3 million gallons. The process slows down the flow speed of rainwater runoff compared to a normal concrete rooftop. This keeps the area from flooding during heavy rains.
The roof’s terraces are filled with organically grown crops, including a drought tolerant variety of rice, many local vegetables and herbs. The farm can supply the canteens on campus with a large amount of rice, herbs and vegetables a year. The food waste is composted (把……制成堆肥) to fertilize the farm, and water from the storage ponds is used to water plants, creating an entirely localized and circular system.
The farm serves as an outdoor classroom and a source of local jobs, too. Farmers offer workshops on sustainable agriculture and nutrition as part of the university’s sustainability curriculum. “Students and community members are invited to participate in seasonal seeding, harvesting, and so on,” says Voraakhom. “The urban farm is training a new generation of organic farmers with real-world skills. It also promotes a sense of community.”

5 . Most of us have heard of the 3Rs: reduce, reuse and recycle. It is the core principle of a sustainable (可持续的) life, but few of us can apply it in our own lives. Now, there’s a “lab” you can explore and discover a way toward living sustainably.
3R Lab is located in Xuhui district, Shanghai. It offers exhibitions, activities and goods that showcase the 3R principle. The key to a sustainable life, according to Vincent T. M. Fong, the 32-year-old from Hong Kong who created the lab, is to make it a long-term promise. “A sustainable life should be sustainable itself in the first place. You can’t lead a sustainable life on a whim. Small and comfortable changes are exactly what you need,” Fong said.
The lab regularly hosts ugly fruit markets, offering these strange fruits which are often thrown away by traditional markets and consumers at a quite attractive price. “They’re thrown away simply because of their appearance. Buying fruit regardless of how they look reduces food waste significantly in our daily life,” Fong commented.
A water tank with two types of straws is another equipment in the lab. “One type is made from normal plastics widely used in our daily life while the other is from PHA, a new replacement for plastics, and the water is sourced from the Suzhou River,” explained Ni Li, an employee of the lab. Visitors can see how the PHA straws degrade (降解) into a thin layer in just one month, while the others remain unchanged.
“Leading a sustainable life does not necessarily mean sacrifice,” said Fong. Consuming ugly fruit and using degradable plastics are small changes that are good for the environment and easy to stick to. Only in this way can the 3R principle become part of our lives, he added.
After working there for six months, Ni, who wasn’t mindful of the 3R principle before arriving at the lab, now uses her cup every time she buys a coffee. “The job has reshaped my life,” Ni said.

7 . Last Friday, Britain’s Prince William announced the winners of this year’s Earthshot Prize. The prize is meant to encourage new ideas and rapid action to help protect the planet. Below are parts of this year’s prize-winning projects in each category.
Protect and Restore Nature
Kheyti won the prize for protecting and restoring nature with its “Greenhouse-in-a-box” idea. Kheyti is already working with 1, 000 farmers across India, which is one of the most climate-affected countries in the world. The company says the greenhouses allow farmers to use 90% less water and produce seven times as much food. Kheyti hopes to get its greenhouses to 50,000 farmers by 2027.
Clean Our Air
Charlot Magayi won the prize for cleaning the air. Ms. Magayi developed a stove (炉子) that uses a fuel that’s cheaper and pollutes far less than charcoal stoves. Currently, over 200,000 of her Clean Stoves are being used in Kenya.
Build a Waste-Free World
A London-based company called Notpla(for “Not Plastic”)won the prize for building a waste-free world. They’ve created a plastic substitute(替代品)from plants found in the ocean. Unlike most plastic, their products break down naturally with no microplastics. Notpla believes their products can help end the plastic pollution that’s filling landfills and polluting oceans.
Fix Our Climate
The Earthshot Prize for working toward fixing our climate went to a company called 44.01 from Oman. 44.01 has come up with a way to turn polluting carbon dioxide(CO2)into a rock called peridotite. Once the CO2 has been turned into rock, it can no longer be released into the atmosphere again. The method that 44.01 uses is fast, cheap and permanent.

9 . On September 7, 1991, the costliest hailstorm (雹暴) in Canadian history hit Calgary’s southern suburbs. As a result, since 1996 a group of insurance companies have spent about $2 million per year on the Alberta Hail Suppression Project. Airplanes seed threatening storm cells with a chemical to make small ice crystals fall as rain before they can grow into dangerous hailstones. But farmers in east-central Alberta — downwind of the hail project flights — worry that precious moisture (水分) is being stolen from their thirsty land by the cloud seeding.
Norman Stienwand, who farms in that area, has been addressing public meetings on this issue for years. “Basically, the provincial government is letting the insurance companies protect the Calgary-Edmonton urban area from hail,” Mr. Stienwand says, “but they’re increasing drought risk as far east as Saskatchewan.”
The Alberta hail project is managed by Terry Krauss, a cloud physicist who works for Weather Modification Inc. of Fargo, North Dakota. “We affect only a very small percentage of the total moisture in the air, so we cannot be causing drought.” Dr. Krauss says. “In fact, we may be helping increase the moisture downwind by creating wetter ground.”
One doubter about the safety of cloud seeding is Chuck Doswell, a research scientist who just retired from the University of Oklahoma. “In 1999, I personally saw significant tornadoes form from a seeded storm cell in Kansas,” Dr. Doswell says. “Does cloud seeding create killer storms or reduce moisture downwind? No one really knows, of course, but the seeding goes on.”
Given the degree of doubt, Mr. Stienwand suggests, “It would be wise to stop cloud seeding.” In practice, doubt has had the opposite effect. Due to the lack of scientific proof concerning their impacts, no one has succeeded in winning a lawsuit against cloud-seeding companies. Hence, private climate engineering can proceed in relative legal safety.
