1 . Masks that helped save lives during the coronavirus pandemic are proving a deadly threat for wildlife.
Macaques (猕猴) have been spotted chewing the straps off old and tossed-aside masks in the hills outside Malaysia’s capital Kuala Lumpur — a potential choking threat for the diminutive monkeys. And in an incident that captured headlines in Britain, a gull (海鸥) was rescued by the RSPCA in the city of Chelmsford after its legs became tangled (缠绕) in the straps of a disposable (一次性的) mask for up to a week. The animal welfare charity was alerted after the bird was spotted, motionless but still alive, and they took it to a wildlife hospital for treatment before its release.
The biggest impact may be in the water, with green groups alarmed at the flood of used masks, latex (乳胶) gloves and other protective gear finding their way into already polluted seas and rivers. Conservationists in Brazil found one inside the stomach of a penguin after its body washed up on a beach, while a dead pufferfish was discovered caught inside another off the coast of Miami.
French campaigners Operation Mer Propre found a dead crab trapped in a mask in a saltwater lagoon near the Mediterranean in September.
Masks and gloves are “ particularly problematic” for sea creatures, says George Leonard, chief scientist from US-based NGO Ocean Conservancy.“When those plastics break down in the environment, they form smaller and smaller particles. Those particles then enter the food chain and impact entire ecosystems,” he added.
There has been a shift towards greater use of reusable cloth masks, but many are still choosing the lighter single-use varieties. Campaigners have urged people to throw them away properly and cut the straps to reduce the risk of animals becoming trapped. Oceans Asia has also called on governments to increase fines for littering and encourage the use of washable masks.

5 . Although we're surrounded by millions of bricks every day, most of us don't think about them too often. For thousands of years, the humble clay-fired bricks haven't changed.
They're made from natural materials, but there are problems with bricks at every step of their production. Bricks are made from clay—a type of soil found all over the world. Clay mining is harmful to plant growth. In conventional brick production, the clay is shaped and baked in kilns(窑) mostly heated by fossil fuels, which contributes to climate change. Once made, bricks must be transported to construction sites, generating more carbon emissions. With so many bricks produced globally, their impact adds up.
Gabriela Medero, a professor at Scotland's Heriot-Watt University, decided to find solutions to that. With her university's support, Medero set up Kenoteq in 2009. The company's signature product is the K-Briq. Made from more than 90% construction waste, Medero says the K-Briq—which does not need to be fired in a kiln—produces less than a tenth of the carbon emissions of conventional bricks. With the company testing new machinery to start scaling up production, Medero hopes her bricks will help to build a more sustainable world.
The K-Briq will be comparably priced to conventional bricks. Additionally, as a new product, the K-Briq has been subjected to strict assessment and authoritative certification. Reusing old bricks is an expensive process and there is no standardized way to check the strength, safety or durability (耐久性) of recycled bricks. Medero says that K-Briq could solve both these problems. She claims that K-Briq is stronger and more durable than fired clay bricks.
Over the next 18 months, Medero plans to get K-Briq machines on-site at recycling plants. "This will reduce transport-related emissions because trucks can collect K-Briq when they drop off construction waste," says Medero.

6 . Keeping curious kids from disrupting wildlife
Interacting with the wild, naturally curious kids tend to collect seashells at the beach or keep small wildlife as pets.
Take an interest, not things. Kids show interest in picking flowers, rocks, or shells outdoors. They’re part of wildlife's habitat and play an important role.
Admire animal afar, not disrupt nearby. The urge to take a photo with a squirrel, bird, or slow-moving turtle can be strong for kids.
Take well-worn paths, not off-road romps (嬉戏). Kicking piles of leaves, stepping on bushes, and walking through forested areas can unintentionally scare wildlife. If surprised animals defend their homes, everyone could get hurt. Nobody likes having a guest come in and destroy their home and act rudely.
| A．Keep snacks away from animals. |
| B．Share food if animals are hungry. |
| C．Exposure to them develops kids’ love and curiosity. |
| D．The same rule applies to visiting wildlife in their homes. |
| E．Animals rely on plants for hiding; rocks and shells, for homes. |
| F．Approaching animals disrupts what they do for survival, such as eating. |
| G．Despite innocent purposes, kids’ curiosity accidentally damages the wild. |
Pollution's serious effects on the environment have become more obvious in recent years. Most scientists agree that efforts are necessary to protect our environment from further harm.
As we know, the construction industry consumes a large quantity of energy and resources and creates a huge amount of pollution. So green buildings are in great need.
The environmental benefits of green buildings includes the protection of ecosystems and biodiversity(生物多样性)，improved air and water quality, less waste flowing into streams and the protection of natural resources. Green buildings can also result in lower operating costs because they typically use less energy and fewer materials and improve indoor air quality, improving the health of people who live there.
The process of building green houses includes technical and artistic planning with nature protection in mind. Building designs often reflect the surrounding environment and natural resources and use renewable building materials such as bamboo and straw. In addition, recycled resources found locally are used for green buildings, reducing the cost and air pollution associated with transporting materials long distances.
Care site selection is important to minimize human effects on the surrounding environment. For example, placing a structure in an area that allows it to take advantage of cool breezes and sunlight can reduce energy use and expenses. More energy and expenses are needed for large buildings as well? so it is important to build the small ones.
Green roofs are another feature of green houses that reduce energy use and costs. These roofs are partially or completely covered with plants? which helps to keep heating and cooling costs low? prevent water running off and deal with pollutants.
Other features of green buildings often include energy and water protection, recycling and waste reduction. In addition, renewable energy sources such as solar power, water power and wind power are used for heat and electricity, which greatly reduces costs and decreases the influence on the environment.
8 . If you wear contact lenses (隐形眼镜), you might not know the best way to deal with old ones. Washing them down the sink or flushing them down the toilet is not the way to go. Yet one in five people who wear contact lenses do just that. However, the plastic in their lenses can linger (存留), polluting both water and land.
Rolf Halden, an engineer at Arizona State University in Tempe, and his team created an online survey. More than 400 contact lens wearers took part. The questions asked how many got rid of their lenses inappropriately. About 20 percent — one in five — sent their used contact lenses down sink drain or toilet. Assuming all contact lens wearers in the U. S. do that at the same rate, the researchers then calculated how much plastic would be flushed away each year. Their estimate: 6 to 10 metric tons! That's about the weight of two to three adult African forest elephants. Contact lenses are a tiny part of the world's plastic pollution. But the unique plastic used in contact lenses could make them a big concern.
To figure it out, researchers exposed contact lenses to the microbes (微生物) used to clean wastewater in water-treatment plants. These microbes made the plastics begin to fall apart, but they weren't fully broken down. Instead, they created a lot of tiny pieces called microplastics.
Halden worries that these small plastic bits will cause trouble in the food chain. In water, the plastics from contact lenses sink. Animals could view these tiny bits as food. But because the plastic won't provide them with nutrition, this could threaten the health of animals who dined on it.
And that's already happening. Many studies have shown that corals, larval fish and shellfish are mistaking microplastics for food. Over time, they risk accumulating even higher levels of plastic in their bodies. Also the pollution has already shown up in bottled water, sea salt and fish sold for human consumption.

9 . More than half the world’s population live in cities, and by 2050 the UN expects that proportion to reach 68%. This means more homes, roads and other infrastructure. In India alone, a city the size of Chicago will have to be developed every year to meet demand for housing. Such a construction increase is a bad sign for dealing with climate change, because making steel and concrete, two of the most common building materials, generates around 8% of the world’s CO2 emissions (排放). If cities are to expand and become greener at the same time, they will have to be made from something else.
Wood is one of the most promising sustainable (可持续的) alternatives to steel and concrete. It is not, however, everyday wood that is attracting the interest of architects.
Rather, it is a material called engineered timber. This is a combination of different layers, each designed to meet the requirements of specific parts such as floors, panels and beams (横梁). Designers can use it to provide levels of strength like steel, in a product that is up to 80% lighter. In addition, engineered timber is usually made into large sections in a factory for future use, which reduces the number of deliveries to a construction site.
According to Michael Ramage of the University of Cambridge, a wooden building produces 75% less CO2 than a steel and concrete one of the same size. However, if building with wood takes off, it does raise concern about there being enough trees to go round. But with sustainably managed forests that should not be a problem, says Dr Ramage. A family-sized apartment requires about 30 cubic metres of timber, and he estimates Europe’s sustainable forests alone grow that amount every seven seconds. Nor is fire a risk, for engineered timber does not burn easily. Besides, fireproofing layers can be added to the timber. All in all, then, it looks as if wood as a building material may get a new lease of life.

10 . Biofuels (生物燃料), gained from plants and animal matter, are a key solution to the environmental problems caused by fuels like coal. “Bioalcohol (生物酒精) is the most common biofuel and is produced by sugars found in materials such as corn. With some engine redesigned, it can be used directly by cars, buses, etc.,” says Professor Daniel Tan, “12 percent of transport fuel could come from biofuels, especially bioalcohol, by 2030.”
But a 2016 study of biofuels said, “Bioalcohol presently is mostly produced with food crops. Altogether, the environmentally-friendly biofuels rely on about 2-3 percent of the global water and land used for agriculture, which could feed a large number of hungry people.”
Energy experts have therefore been trying to deal with the problem. Recent research led by an international team found that the agave (龙舌兰) plant might offer a way out. This plant tends to be the right bioalcohol source to supersede others such as sugarcane (甘蔗) and corn.
Daniel Tan explains that the agave can be grown in unfavorable conditions and is not a major food crop. “It can grow in areas that lack water and rainfall without being watered by farmers, and it does not compete with food crops or put demands on limited water. This kind of useful plant is recently being grown in Australia. It can survive Australia's hot summers,” he says.
The study finds that sugarcane produces just a little more fuel per square meter each year than the agave. However, the agave outperforms sugarcane in a range of areas, including pollution to the earth, and water using. The agave uses 69 percent less water than sugarcane and 46 percent less water than corn for the same amount of fuel produced. As for corn，it produces less fuel per square meter each year than the agave.
However, Daniel Tan states: “The first generation of bioalcohol from the agave recently faces a big competition from oil, whose recent low price makes it far more attractive to customers. Without some policy support from the government, bioalcohol production from the agave faces big challenges.”
