Gardeners who use pesticides (杀虫剂) are contributing to the decreasing population of British songbirds, a study suggests. Researchers have advocated stopping using poisonous chemicals in gardens in order to reduce the loss of birds and adopt wildlife-friendly practices instead. The results of the University of Sussex study, which researchers call the first of its kind, were published in the journal Science of the Total Environment.
The study, which examined information on pesticide use and garden management from 615 garden owners in Britain, found 32 percent of gardens used pesticides, and the number of house sparrows was 25% lower when glyphosate-based herbicides was used regularly. Slug pellets (鼻涕虫杀虫剂) also seemed to have an impact on bird sightings; in gardens where Slug pellets were used, house sparrow numbers were down by almost 40%.
Prof. Dave Goulson, of the school of life sciences at the University of Sussex, said, “The UK has 22 million gardens, which collectively could be a fantastic shelter for wildlife, but not if they are overly tidy and sprayed with poisons. We just don’t need pesticides in our gardens. Many towns around the world are now pesticide free. We should simply ban the use of these poisons in cities, following the example of France.” The Royal Horticultural Society, the UK’s leading gardening charity, said the use of pesticides and herbicides should be avoided if possible and they should only be used, if ever, in small and targeted applications.
The research also found that those who adopted wildlife-friendly practices such as planting native bushes and flowers, or digging a wildlife pond, saw more birds than those who did not. Cannelle Tassin de Montaigu, a PhD researcher within the school of life sciences and an author of the study, said, “It’s encouraging to find that simple measures, such as planting native bushes and trees and creating a pond, together with avoiding the use of pesticides, really make a measurable difference to the number of birds you will see in your garden.”

【推荐1】In the Watertown offices of planning and design firm Sasaki Associates, there’s a wall that asks employees to respond to the question, “What makes you happy?” Standing out among a sea of sticky notes listing things like “yoga” and “my cat,” one post says “CHICKENS.”
At most companies it would sound like a joke, but not here. Sasaki, which has an on-site, employee-run garden featuring 30 different kinds of fruits, vegetables, and herbs, is soon adding a chicken coop (笼子) to the mix, and workers seem delighted.
In 2015, Sasaki partnered with Green City Growers, a Somerville —based company that installs (安装) and helps maintain urban farms and vegetable gardens, to give its employees a chance to grow their own produce and experience urban agriculture firsthand.
“It builds a culture of inclusion and community,” said James Miner, a managing principal at Sasaki, who brought the farming idea to the company’s parking lot. “It’s something people can get behind and enjoy. You can just take 10 to 12 minutes away from your screen, get your fingers dirty, talk to your neighbors, and hopefully harvest something.”
While Miner hoped a handful of employees would be excited to take part in the gardens, he was happily surprised when nearly 40 percent of the Watertown office’s employees jumped onboard.
Completely, funded by Sasaki, the company’s urban gardens are owned and tended by employees, who can sign up to manage crops by themselves or in groups. Workers bring home whatever produce they grow —cucumbers, tomatoes, eggplants, and scallions are just a few of the foods they’ve had success with.
After the addition of the bright pink chicken coop — which will be designed and 3D —printed in Sasaki’s offices —the employees hope to add a garden and explore beekeeping on the building’s roof. Quite a few closet beekeepers, gardeners, and birdwatchers have emerged from the company’s woodwork to lead the charge on these plans.
“People are looking for a higher sense of meaning at work,” Miner said. “The gardens show what it means to be a part of Sasaki.”

【推荐2】I’d been telling Sandy about my children, Emma and Tucker, aged seven and four. Sandy, in turn, was telling me about her four children: Jane, Joe, Christopher and eighteen-month-old Kim. She seemed so pleased to have kids move into the neighborhood. That was, until the door opened and out ran Emma and Sam.
Sam was our shiny black dog we had adopted three years earlier. Sam loved to hang with the kids, serving as both playmate and protector. But Sandy began to back up as Sam approached, I had never met anyone who feared dogs. As I saw her reaction, I quickly grabbed Sam by the collar and made him sit.
“I have to get the kids ready to go to their grandmother’s,” Sandy said as she backed away from me, graciously trying to remove herself from the situation.
Suddenly her door opened, and out ran her kids. “Don’t go near it!” she screamed. The kids were circled around their mom, closely watching Sam. Emma showed Joe the proper way to slowly approach a dog. Sam accepted Joe’s affection. The kids were won over, but I knew it would take some time before Sandy would change.
From that time forward, we were careful not to let Sam cross the street to our neighbors without my company. One day, the kids were across the street playing together. Then I noticed the eighteen-month-old heading toward a little hill. Seeing a car approaching, I screamed, “Watch the baby!”
Sam stormed out the door and ran across the street toward the baby. He ran up the hill, stopping just short of knocking into her. He gently pushed her away from the approaching car. The kids, too involved in play to realize the seriousness of the situation a few minutes ago, ran toward her and Sam. The kids all cheered that Sam had come to play.
Within a year, Sam made friends with all the neighbors, and almost every family on our street had a dog. Even Sandy would occasionally come and give Sam a hug.

【推荐3】Saving the giant panda from extinction isn't just good for the bears-it's good for the bottom line too,a new analysis by an international team of scientist shows.
The results,published in the journal Current Biology,highlight the economic benefits that they say go hand in hand with environmental conservation. In order to protect giant pandas,the government must protect their forests,which provide a host of often-under appreciated services to the communities that live in and around them. For example,forests allow for the growing of crops and the grazing(放牧)of animals,store clean fresh water and supply firewood,lumber(木材)and many useful plants.They manage storm runoff and help prevent erosion(侵蚀)。
The pandas themselves also hold enormous cultural value that has risen rapidly in recent decades among Chinese residents,the study also points out. "From 1980 to 2010,the cultural values of pandas and their reserves almost doubled,largely driven by tourism use,rising 500-fold from 1980 to 2010, "they said.
Taking all of these factors into account,the scientists calculated a total economic value of Approximately $2. 6 billion in 2010 in China. Keep in mind,the costs of preserving panda habitat at current levels come to about$255 million. The study authors said that including the global cultural Value of the animals would increase the total economic value to $6. 9 billion per year-or about 27 times the cost of habitat preservation.
The researchers also noted that the investment in panda habitat has improved the living conditions of local residents. They pointed to data from the Chinese Statistical Yearbook showing that the annual income in Sichuan, Shanxi and Gansu provinces,which sit next to panda reserves,rose by an average of 56%from 2000 to 2010. Farmers in counties within these provinces that were next to the panda reserves saw their annual incomes rise by 64%,on average.
The findings provide a promising example of how conservation efforts can pay off,and they could be applied to many other threatened and endangered species,the study authors said.

【推荐1】If you’ve never had hot pot, you’re absolutely missing out. Not only is it delicious, but it’s also a fantastic meal to share with friends or family. But it also generates a lot of waste oil. In fact, hot pot is reportedly responsible for 12,000 tons of waste oil per month just in the Chinese city of Chengdu alone. Instead of just throwing away that oil, one company decided to turn it into jet fuel (航空燃料).
Bloomberg recently published a great article about Sichuan Jinshang Environmental Technology, a company that began exporting hot pot waste oil to be turned into biofuel that can power planes. It’s not exactly a perfect solution to the greenhouse gas emissions that the aviation (航空) industry is responsible for, but it’s a step in the right direction. “Our mission is to make waste oil fly to the sky,” Zhong Guojun, the company’s vice president, told Bloomberg.
Based in Chengdu, Sichuan Jinshang Environmental Technology takes waste oil from around the city and refines it into something called industrial mixed oil. The refined oil is then exported to be turned into jet fuel or biodiesel (生物柴) by companies such as BP or Neste Oyj, the biggest producer of sustainable jet fuel in the world. And with new requirements for airlines to use more biofuel in their planes, there’s a lot of demand despite the fact that it’s still more expensive than regular jet fuel.
“When there is a demand, the supply will catch up, and the demand is already here,” said Chong Cheng Tung, Associate Professor at the China-UK Low Carbon College, Shanghai Jiao Tong University told Bloomberg. “So either you switch your fuel to green fuel, like bio-jet fuel, or you have to meet additional payments for travelling.”
Last year, Neste announced plans to spend more than $2 billion expanding its capacity to produce sustainable jet fuel. By 2026, it hopes to be able to produce 1.2 million tons of the stuff. Other companies such as Chevron, BP. and Total Energies are producing it on a smaller scale (规模) but also plan to increase their output soon.

【推荐2】Climate change disproportionately affects the world’s most vulnerable people, particularly poor rural communities that depend on the land for their livelihoods and coastal populations throughout the tropics. We have already seen a chain of tough suffering that results from extreme weather events, such as hurricanes, floods, droughts, wildfires, and more.
For remedies, advocates and politicians have tended to look toward cuts in fossil-fuel use or technologies to capture carbon before it enters the atmosphere—both of which are crucial. But this focus has overshadowed the most powerful and cost-efficient carbon capture technology in the world. Recent research confirms that forests are absolutely essential in reducing climate change, thanks to their ability to absorb and isolate carbon. In fact, natural climate solutions such as conservation and restoration of forests, along with improvements in land management, can help us achieve 37 percent of our climate target of limiting warming to a maximum of two degrees Celsius above preindustrial levels, even though they currently receive only 2.5 percent of public climate financing.
Forests’ power to store carbon dioxide is staggering: one tree can store an average of about 48 pounds in one year. Intact(完整的)forests could take in the CO2 emissions of some entire countries.
For this reason, policymakers and business leaders must create and enforce policies to prevent deforestation, foster, reforestation of degraded land, and promote the sustainable management of standing forests in the fight against climate change. Protecting the world’s forests ensures they can keep performing essential functions such as producing oxygen, filtering water and supporting biodiversity. Not only does the world’s entire population depend on forests to provide clean air, clean water, oxygen and medicines, but 1.6 billion people also rely on them directly for their livelihoods.
Unfortunately, a huge amount of forest continues to be converted into agricultural land to produce a handful of resource-intensive commodities - despite zero-deforestation commitments from companies and governments. So now is the time to increase forest protection and restoration. This action will also address a number of other pressing global issues. For example, in less developed, rural areas - especially in the tropics - community-based forest-management programs can forge pathways out of poverty. In the Peten region of Guatemala, for instance, community-managed forests boasted a near-zero deforestation rate from 2000 through 2013, as compared with 12 percent in nearby protected areas and buffer(缓冲)zones. These communities have built low-impact, sustainable forest-based businesses that have stimulated the economy of the region enough to fund the creation of local schools and health services. Their success is especially noticeable in a location where, outside these community-managed zones, deforestation rates have increased 20-fold.

【推荐3】The UN this week launched a report urging companies to stop issuing false net-zero targets that amount to greenwashing.
Greenwashing is a term used to describe situations where companies mislead consumers by claiming to be eco-friendly or sustainable as a marketing plan rather than as a core principle of their business model. Often, these industries spend more money making themselves appear sustainable than they do taking actual sustainable measures into their company.
Cities, financial institutions, and scores of companies have announced plans to reduce their emissions to zero, which, in principle, should help the fight against climate change.
“The problem is that the criteria for these net-zero commitments have varying levels of precision and loopholes (漏洞),” said UN Secretary-General Antonio Guterres during the launch of the report.
Many net-zero plans contain far-away or unclear targets and often call for the use of unproved technologies like carbon capture and tree planting, which effectively allow companies to continue polluting the atmosphere. Studies show that most of these net-zero plans will do little to stop temperatures from rising. For example, many oil majors have announced plans to reduce emissions from their operations to zero by 2050 that do not take into account the carbon emitted by the fossil fuels they sell, which would allow them to increase production. Far from decreasing, fossil fuel production is going strong.
To close these net-zero loopholes, the UN this week released a report that includes 10 recommendations to ensure that companies, cities, regions, and other non-state actors issue credible and accountable net zero commitments. “Their plans cannot rely on cheap carbon credits instead of immediately cutting their own emissions,” Guterres said.
Financial institutions need to cut down emissions from all their investments and businesses need to bring down the carbon footprint of their supply chain, the report said. The report’s lead author, Catherine McKenna, urged companies to release new net-zero targets within a year. The updated targets must contain concrete actionable details.
1. What does “greenwashing” refer to?A.A green technology. | B.A misleading statement. |
C.A business model. | D.A spending target. |
A.To prove oil majors are really responsible. |
B.To set some good examples for other companies. |
C.To show some net- zero commitments make no sense. |

【推荐1】A book is made of wood. But it is not a tree. The dead cells have been repurposed to serve another need.
Now a team of scientists has repurposed living cells—scraped(刮落)from frog embryos—and assembled them into entirely new life forms. These millimeter-wide “xenobots” can move toward a target, perhaps pick up a payload(like a medicine that needs to be carried to a specific place inside a patient)—and heal themselves after being cut.
“These are novel living machines,” says Joshua Bongard, a computer scientist and robotics expert at the University of Vermont who co-led the new research. “They're neither a traditional robot nor a known species of animal. It's a new class of artifact:a living, programmable organism.” “We can imagine many useful applications of these living robots that other machines can't do,” says co-leader Michael Levin, “like searching out nasty compounds or radioactive contamination(污染物), gathering microplastic in the oceans, traveling in arteries(动脉)to scrape out plaque.”
People have been manipulating(操纵)organisms for human benefit since at least the dawn of agriculture, genetic editing is becoming widespread, and a few artificial organisms have been manually assembled in the past few years—copying the body forms of known animals. But this research, for the first time ever, “designs completely biological machines from the ground up," the team writes in their new study.
Many people worry about the implications of rapid technological change and complex biological manipulations. "That fear is not unreasonable,” Levin says. "When we start to deal with complex systems that we don't understand, we're going to get unintended consequences.” “If humanity is going to survive into the future, we need to better understand how complex properties, somehow, emerge from simple rules,” says Levin. Much of science is focused on "controlling the low-level rules. We also need to understand the high-level rules." In other words, “this study is a direct contribution to getting a handle on what people are afraid of, which is unintended consequences,” Levin says.

【推荐2】A child’s early years of language development are important for the basics of school readiness, such as literacy (读写) skills and social and emotional growth. In a recent study, University of Miami Assistant Professor of Psychology Lynn Perry and a team of fellow researchers who examined child speech communications over the course of a year found that children benefit from conversations with their peers (同龄人) and their teachers. The study examined how language use and development in 2-and 3-year-old children was influenced by what they heard from their teachers and their peers.
“Previous research on language development looked mostly at the role of parent-child communication within a home setting or a lab environment, which means we’re missing a big part of a child’s everyday life — the classroom,” said Perry. “We know that parent language is important for children’s development and their academic achievement, but we don’t have much research on what happens in the kindergarten or preschool setting.”
Using a device (设备) called a Language Environment Analysis (LENA) recorder, Perry collected hundreds of hours of audio recordings. Children wore the LENA recorder once a week. LENA software then assessed whether the recorded audio was speech or not, and whether the speech came from the child wearing the recorder or from an adult or another child talking to them.
After studying the audio data, Perry found that the speech children heard from other children was positively related to their own language use, meaning children who heard the most from their peers learn more new words and vocalize more during the course of the year. Additionally, there was a positive association between a teacher talking and children’s language use and development — but only when that teacher talked to the child in a back-and-forth conversation, rather than just talking to the child with no opportunity for the child to respond.
“One important aspect of the study that stands out to me is how important it was to see those conversational turns with teachers, and that back-and-forth conversation with the child is very beneficial. We talked to the teachers about the results, and they are very excited about this finding and currently brainstorming additional opportunities to have conversations with children,” adds Perry.

【推荐3】Long-term pain may not be an inevitable consequence of bad posture, but the notion that “good” posture is beneficial isn’t completely ill-founded. Certain postures can lift your spirits.
An awareness of a link between our body and our emotions goes back to the 19th century, when philosopher William James suggested that we don’t laugh because we are happy, but rather we are happy because we laugh.
This idea is now known as “embodied cognition”, where the body influences our thoughts. For instance, when you meet a loved one, your heartbeat may increase and you might feel their skin against your own as you embrace. The brain, which is constantly assessing changes to information from the outside world and from our internal body, combines this new data and generates the appropriate emotion. Only then do we consciously sense the feeling of love, or joy.
Several experiments support this idea, for instance, studies by Elizabeth Broadbent at the University of Auckland, New Zealand. Her team randomly split people without depression into two groups, using physiotherapy tape to strap their back into either a bent or upright seated position. The participants then gave a speech. Afterwards, the upright group not only reported a more positive mood, but were less stressed as measured by blood pressure.
In another experiment, students were initially shown positive and negative words and asked how well each word described them. They were then guided into walking in a style that resembled that of someone who was unhappy or extremely happy.
At the end of the study, the participants were given a surprise test—to remember as many words from the start of the study as possible. Participants recalled more negative words when walking in a style that resembled individuals who are sad than they did when walking with a happier gait (步态). The researchers suggest that the walking style may have triggered a change in emotional state, which then affected memory recall.
