1 . A new study suggests classic paintings by well-known Impressionists Joseph Turner and Claude Monet may have been influenced by air pollution during the Industrial Revolution.

Scientists don’t know exactly how polluted the cities were during that time for lack of data. However, researchers say that examining the works of Turner and Monet can give a picture of long-term environmental change with the air pollution.

The study, published in Proceedings of the National Academy of Sciences by authors from Harvard and Sorbonne universities, analyzed 60 oil paintings by Turner from 1796 to 1850 and 38 paintings by Monet from 1864 to 1901. Scientists successfully measured painters’ representation (再现) of nature, focusing on the colors as well as differences in local weather patterns which influenced coloring. They significantly found that paintings composed in Britain generally feature a greyer blue sky than works in other parts of Europe.

Researchers particularly believe changes in local sulfur dioxide (二氧化硫) emissions from burning coal may explain changes in the color contrast and intensity (亮度) of Turner’s and Monet’s works, even after taking into account the artistic trends and subject matter of the time.

Generally, artists can historically accurately represent their environment. Turner and Monet were chosen because they are famous for their landscape and cityscape paintings and also because they were active during the Industrial Revolution, when air pollution grew at a rate never seen before.

Additionally, researchers say that since the air in London was much polluted, the cities would appear grey and dull to the eyes as well as in photographs. By comparing the paintings of Turner and Monet to photos from the era, they were able to determine the painting works were definitely influenced by the change in emissions.

3 . Nanako Hama gets a lot of mail, mostly from strangers who live in her home city of Tokyo. In light envelopes, they send locks of their hair, hoping to recycle it.

People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change.

But hair possesses useful qualities and it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子) out of it for removing oil leaks,

Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mats, which are then used to clean up the floating oil.

“Hair is particularly well-suited for this,” says MoT co-founder Lisa Gautier, “That’s because its rough sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks, including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.

In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney, in Australia found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair — significantly more than polypropylene (聚丙烯), a type of plastic that’s typically used to clean up floating oil.

Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen (氪), a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.

“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes-for oil and soil, ” Hama says.

5 . Drive through any suburb in the U. S. today, and it’s hard to miss the recycling bins that have become companions to America’s trash cans. Recycling has become common, as people recognize the need to care for the environment. Yet most people’s recycling awareness extends (延伸) only as far as paper, bottle, and cans. People seldom find themselves facing the growing problem of e-waste.

E-waste rapidly increases as the techno-fashionable frequently upgrade to the most advanced devices, and the majority of them end up in landfills (填埋). Some people who track such wastes say that users throw away nearly 2 million tons of TVs, VCRs, computers, cell phones, and other electronics every year. Unless we can find a safe replacement (替代品), this e-waste may get into the ground and poison the water with dangerous toxins (霉素), such as lead, mercury, and arsenic. Burning the waste also dangerously contaminates the air.

However, e-waste often contains reusable silver, gold, and other electrical materials. Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals, which can destroy ecosystems.

A growing number of states have passed laws to ban (禁止) getting rid of e-waste. Still, less than a quarter of this waste will reach lawful recycling programs. Some companies advertising safe disposal (处理) in fact merely ship the waste to some developing countries, where it still ends up in landfills. These organizations prevent progress by unsafely disposing of waste in an out-of-sight, out-of-mind location.

However, the small but growing number of cities and corporations that do handle e-waste responsibly represents progress toward making the world a cleaner, better place for us all.

6 . Looking to make the biggest impact during a crisis? This guide will help you get the necessary resources to the right people quickly and easily, as well as help you prepare for a potential emergency.     1    .

Put simply, more people equals more money, and creating your own fundraiser is a great way to encourage people who want to help. If you’re dealing with a local natural disaster, start by raising money through your community     2    , on the organization’s site or through an app; thus, you won’t have to deal with transferring donations through your personal account.

    3    . Start by checking an organization’s website; they often have lists of what is needed and where to send it. Or call community offices in the affected area to see what specific needs they have.

You can contact your local emergency services, to see if they are seeking a helping hand. If you don’t have a particular skill, offer your time to help with clean up afterward. However, always call or check online first.     4    . In reality, you will be adding one more person to the already strained situation.

    5    .

One of the most helpful things you can do in a natural disaster is to prepare yourself ahead of time. Not only will these preventive measures protect you, but they will also limit damage in case disaster strikes. The first step is to find out which disasters are most likely to affect you. The second step is stocking up on essential emergency items.

Located in Ordos, North China’s Inner Mongolia Autonomous Region, Kubuqi Desert (库布齐沙漠) is the closest desert to China’s capital Beijing. It was once known as the “sea of death”. However, in the past 30 years, the government, social organizations and local farmers     1     (work) together to control desertification (沙漠化) in Kubuqi Desert.

Historically, Kubuqi was a rich city filled with water and grass. But due     2     climate change and over-exploitation from humans, the farmlands gradually turned to desert. Controlling desertification was the only way out for people still living in Kubuqi. With the first highway going through the desert     3     (build) here, people started planting trees in     4     whole desert. It was common for planted trees to die. But the next year, people just continued to plant more trees.     5     (ultimate), their hard work inspired the term “Kubuqi spirit”, encouraging local people     6     (devote) themselves to the desert greatly. Over three decades, tree planting technology saw further     7     (improve) in Kubuqi. Now workers can plant a tree in just ten     8     (second), and the survival rate of trees is over 80 percent.

The 102,000 residents in the desert have enjoyed the benefits of managing with desertification. Meng Keda,     9     family has lived deep in Kubuqi Desert for generations, began a tourism business in 2006     10     earned about 300,000 yuan last year.

9 . An earthquake can strike without warning. But many injuries and deaths from this kind of natural disaster can be prevented if people follow these safety tips.

If you’re inside a building, stay there! One of the most dangerous things to do in an earthquake is to try to leave a building.     1     Drop down onto the ground. Get under an object that is not easily damaged. Hold on to it until the shaking stops. You can also get to a corner formed by two walls with your arms over your head. If you’re in bed when the quake hits, stay there and protect your head with a pillow.

    2     Don’t take shelter under trees, streetlights, telegraph poles or tall buildings. If you are driving stop as quickly as possible and stay away from overpasses, buildings, bridges or anything else that might fall or collapse over you.     3    

If you are trapped in the ruins, cover your mouth with a handkerchief or a piece of clothing. Use your cellphone to call for help if possible. Don’t shout.     4     Tap on a pipe or the wall so rescuers can find you.

Be prepared for aftershocks    5     However, sometimes they even happen months later. Therefore, if you are not in a safe position after the first shock, you should move quickly but carefully to a safer place.

10 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.
